    INTRO: Brief Introduction


    Welcome to The Ruddle Show. I’m Lisette and this is my dad, Cliff Ruddle. How are you doing?


    Ready to do 50.


    Well, we have a very special show for you today, and we’re pretty excited about it and it’s going to be a busy show, so we’re going to get going right away.

    MAIN SEGMENT: 50 Shows Special


    Today we are shooting our 50th regular season show, and it’s hard to believe we’ve done 50 shows, but we have. So today, we wanted to show you some highlights from those shows. Now some of you might remember that the symbol for The Ruddle Show is a triangular pyramid, with the sides representing education, community, innovation, and lifestyle. So, let’s start with education, or as you fondly refer to it, the meat and potatoes. What have we covered in terms of education?


    Well, we’ve done quite a bit. In fact, I’m a little stunned as I sit here trying to grasp it all, but we have a lot of diversity in our audience, and they’re international, and we have tens of thousands of people that join, so we have to recognize their backgrounds, their experiences, their training. The skill levels may be a little bit different. We have young dentists, students, still residents. We have young dentists, old dentists, even older than myself.

    So, we’ve tried to, I think, take all that into account and have compelling shows that would cover, I would say, all aspects of clinical endodontics which is my meat and potatoes that you referred to. So diagnostically, we’ve talked a little bit about clinical findings, we’ve talked about vital pulp therapy, we’ve talked about diagnostic things using two-dimensional films, digital, we’ve talked about CBCT and how all that works. We’ve talked about access, orifice directed, ninja and complete access, and then how to find orifices.

    I think we even had a thing, 14 tips or tricks on how to find those aberrant calcified or previously missed canals. After glide – we talked about glide path management and it was like stainless steel, is it NiTi, is it mechanical driven, is it a manual idea, working length, patency, securing canals. We’ve talked about shaping and all those different controversies, terminal diameter, we’ve talked about apical one-third taper. We’ve talked about how that relates to minimally invasive endodontics, so yeah, that’s shaping. And of course, we shaped to clean. We’ve talked a lot about cleaning, haven’t we?




    I mean we’ve talked about not only the aspect of cleaning and getting into the uninstrumented portions of the canal, we’ve talked about the advantages of lasers. We’ve talked about GentleWave, the EndoActivator, and how to agitate those solutions and get them to move into these hard to – well, to all four corners of the root canal system. We’ve talked about different ways to fill. And there was, of course, the new single cone and we’ve talked about that idea. We’ve talked about vertical condensation with warm gutta-percha. We’ve talked about carrier-based obturators.

    I had a big discussion about Ker Pulp Canal Sealer, and we talked about, of course, bioceramics, you know, the tri-calcium silicates, so we’ve talked about a lot. When cases fail, we’ve talked about how to disassemble. We’ve talked about how to remove cores and all metal posts. We’ve talked about gutta-percha removal, silver points, a lot of things like that.

    Broken instruments, we’ve talked about that and even now we’re moving on past staging platforms and those kinds of things as we get into more conservation of root structure. And of course, we’ve had a few flaps up and we’ve talked about flaps and microsurgery. We’ve talked about exploratory treatment. That took us into some osseous crypts to discover why cases might be failing. So, yeah, that was kind of a glimpse across the clinical aspect.


    I think we’ve covered it all. What are we going to talk about next season?


    Well actually, I’ve just gotten started. I mean seriously, we’ve broached on a lot of these things, but we can drill down, and believe me, we will be drilling down and going into much more detail in our next continuums.


    Well, we’ve also done Q&As on a variety of subjects, calcium hydroxide, game changers, pro-taper, glide path management, incorporating new technologies, to just name a few. And we welcomed guests who have expertise in a certain area. Dr. Shanon Patel has talked to us about CBCT. Dr. Gordon Christensen has told us some interesting things about the new glass ionomers. So, why don’t we see some of our education highlights right now? And for those of you who are new to The Ruddle Show, this is what you’ve been missing.

    [video playing]


    How to remove broken instruments. So, whether you broke the instrument, or it’s been referred to you to be removed, there’s several things we need to consider. Cyclic fatigue and torque failures would be the scientific reasons instruments break, but usually it’s related to glide path or the absence of the glide path, and so we did a lot of talk last section, the segment just before, on getting a good, smooth, reproducible glide path.


    Victims of trauma arrive in your office. There’s a lot of times parents involved because these are a lot of times kids or young adults, and oftentimes, there’s a lot of anxiety. There’s tension. And of course, somebody went from a beautiful smile ten minutes ago to now they have puffy lips, broken teeth, maybe broken bones. You can understand, though, that this person is in trouble.


    Improved glass ionomers, what the heck is improved about them? A lot. Anti-microbiologic restoratives. This is the first time in the history of dentistry when something in a resin material will kill the bugs that light on it, and it doesn’t dissipate. We’ll get on to that in a minute.


    Schilder was doing even in 1960, notice, filling root canal systems. Notice, filling root canal systems. Schilder used to say as you get away from the heat source, the gutta-percha will move a little bit laterally, but probably the rest of this could be sealer, so like a car engine where you have a piston and a cylinder block, as you get a piston of gutta-percha moving, it will drive sealer in front of it and get the hermetic seal. So, I wanted it noted Schilder said to keep the foramen as small as practical. I better write that out because a lot of people around the world are trying to go with “possible.” That’s not what Schilder said, he said “practical.” It might be a 20 or a 25 or a 50, it depends.


    So, what advice or tips would you give to a clinician new to CBCT but who wants to become more proficient? Practice?


    Yeah, basically practice or what I would say is taught to endodontists because we use high resolution CBCT scanners, small field of view as well.


    We’re going to – we have a full segment for you on Q&A because we’ve gotten a lot of questions lately, so I have some questions here. We’re going to get through as many as we can. What position do you deem to be the optimal position for working length and why?


    Okay, Schilder said when we see the file, when we see the file and the edge of the periodontal ligament, he said that would be called the radiographic terminus. We’re looking usually at a 10, a 10 file. It could be a 15 or 20, depends on the case, but usually a 10 file we can read radiographically. Usually, we get less false positives with apex locators when we use a little bigger file.

    [video ends]


    Okay, great. So, another aspect of The Ruddle Show is innovation, so why don’t you talk to us about innovation because yes, it does include inventing dental products.


    Well, I’ve talked about the inventor’s journey and, you know, all the way from that nighttime original idea that was sparked in the dead of night to finally grinding along with the years to market version products, so I’ve given you a little bit of discussions on some of my ideas that we’ve worked with, the team concept, you know, ProTaper, WaveOne, glide path instruments, blah, blah, blah. It doesn’t really matter.




    Yeah, oh thank you. The EndoActivator was really fun on that fishing trip. But anyway, some of the guests that came on were very inspiring. Cherilyn Sheets, you’ve already mentioned her, but she did that quantitative diagnostic percussive instrument. I think it was called [InnerView / Perimetrics LLC]. And that would be a way to distinguish between fractures, cement failures, coronal fractures versus radicular fractures. That was pretty cool.

    Then we had that guy from northeast Ohio. I think his name was Nuzum, and Micah basically helped us learn how to practice in a more safe environment in these difficult times, so it was really fun to have him on, and I hear people around the world now that have got a Nuzum unit in their office.


    They have the microscope shield.


    They have the shield. Gordon Christensen, you know, he did a really great one on hot topics, and it was glass ionomers and those new micro or anti-microbiological composites that are coming in, and that was really informative for me. Randy Cross, I always call him “the kid,” but you know, he just graduated, but he gave us this idea about how we could measure residual bacterial loads using biomarkers. That’s going to usher in a whole new future of when are you done shaving and cleaning.

    And then finally, I think we got to Nathan Li, the godfather, the polymer chemist, the micro polymer pulling of the chains and ending those nanoparticles, and he is now the guru, the godfather, of the modern cone. Notice it’s not a point; it’s a cone.


    Well, we’ve also talked about – well okay, let me just say that innovation for us is more than just inventing dental products.




    Cause our goal on the show is to inspire creativity and get you to challenge your assumptions and break old thinking patterns and maybe see the world through fresh eyes. So, when we talk about controversies like those surrounding GentleWave, BC Sealer, access cavities, excessively heat-treated files, minimally invasive endodontics, well we’re challenging you to see something in a different way than maybe you normally would, but we also just don’t want you to believe everything we say, either. We want you to question and think critically because questioning, that’s how innovation starts in the first place. So, let’s look at some of our innovation highlights.

    [video playing]


    We talked about how John, you had the idea in the U.S. in the early 90’s about variable tapers on a single file and then at the same time across the Atlantic in France, Pierre was working on developing prototypes for variably tapered files.


    The literature was really kind of up and down. If you look at the older literature, instrumentation caused micro cracks. That was pretty much a foregone conclusion. The more recent literature in the advent of micro-CT said no, there aren’t any, so which is correct? So –


    We agreed, and she shook hands on three things. I said I shall continue if I can, one, to use machine to make those points instead of hand rolling. That was very labor intensive. Two, okay, if I can make a gutta-percha cone with progressive tapers, multiple tapers, to match, precisely match, the ProTaper universal, Ni-Ti files, and three, if I can change the six-year-old formula to better adapt warm gutta-percha condensation technique.


    Why don’t you tell us a little bit about Dr. Cross, how you met him, and maybe tell us a little bit about what he’s working on.


    I met him at Ruddle with the Residents Program that Phyllis set up many years ago, and he was one of the kids out there in the audience and we connected, and then what we connected on was his new innovation, his idea. At that time, it was just a concept about a chairside method to determine the level of remaining bacterial load with a biomarker. So, that was very impressive.


    One thing that really struck me in the presentation, and part of the reason it struck me because we had talked about it on a previous show when we did a segment on the future of endodontics, and in that segment, you had said that there was a trend moving away from mechanical solution toward biomedical solutions, and that seems to be what we are seeing here with the Infinix product which is an antimicrobiologic composite with the benzalkonium chloride in the molecule itself, and that makes any organism that touches it die.


    I was sitting in the plane, and I was going like, you know, I have an idea, and the idea is what if we had a line that was a polymer and we could activate it, sub-orifice level, in a natural tooth, and we could agitate the fluids and get better exchange. So, that’s what I learned on the fishing trip. I came – they got fish; I came home with an idea.


    So, you saw the strong, flexible line and the agitation of the water and so you started –


    Oh, that’s good.


    – thinking, you know, in terms of irrigation, I guess.


    I’m a Pisces.


    So, this is what happens when a master endodontist goes fishing and doesn’t fish.

    [video ends]


    So next up is community, because The Ruddle Show is not just about Ruddle. We want to connect with others in the dental community, share ideas, see what motivates them, and learn how people do things in other parts of the world.


    Very good.


    So, believe it or not, COVID has actually been very helpful in – to enable us to accomplish this goal. Why don’t you explain?


    Well, remember we said crisis, danger, and opportunity. So, basically, what COVID did is it changed things a little bit, but before COVID, we took our first two guests right here from town. I think we had Jesse Brisendine. Wasn’t he the life coach?




    And he gave us some tips on, you know, how to reduce stress. And then we got to my dear pal, Terry Pannkuk, a consummate endodontist, your endodontist, my endodontist, and he basically gave us ways to think about trends in education and how things might be going in the future, and then COVID did come, and that stopped all the personal guests, cause they were in here onsite. And so, we were a little bit dismayed, but then we discovered Zoom.

    And we started Zooming and Zooming and more Zooming and we’re Zoomers, and I hope you are Zooming with us. So, anyway, we got into Zoom and all of a sudden that opened up a lot of possibilities, cause instead of people – we imagined they’d fly in here, take a hotel room, I’d go to dinner with them, and I mean this was going to be great fun for Ruddle, and I was going to hang with these stars cause they were people I admired, and all that went away and we could Zoom, but then we still got them on, so that was great.

    Some of them joined us in Zoom live. Some of them sent in shows, like Gordon Christensen and future shows that we were already working on, just send in the canned show. So, that was all interesting.

    And then we had the COVID specials; we had two of them, and we had five guests on that reported from international what was going on like in Singapore, South Korea, you know, Amsterdam, Canada. We had these people weighing in from Paris, France. So, it was quite interesting to hear how they surmised what was going on early in the game of that pandemic.

    And then later the AAE came around. We had five more guests, and they all basically came on and told us why we should tune in to the AAE’s virtual meeting and watch what they were going to talk about. We had some really interesting people. So –


    Yeah, we’ve explored like what you just said. We’ve also explored community in terms of dental meetings, whose job, which discipline, does certain jobs, you know, certain procedures, we’ve explored that.




    How to maximize your relationship with your dental reps. Patient interactions we’ve talked about. Choosing a dental school or like where do you want to set up your practice.


    Oh yes.


    That’s all community, too.


    Wow, we did all that?


    Even dental service organizations we talked about and concierge dentistry.


    Ah, Gary Glassman, yes.


    Right now, we’re going to look at a few of our community highlights. Now you’ll notice that the guests that we talked about that we Zoomed with, aren’t going to be in this particular video because we have saved something special for them at the end. So, let’s look at our community highlights.

    [video playing]


    In the United States, there’s roughly 350 million people, and there are 180,000 U.S. trained dentists. That’s everybody. In China, you have 1.4 billion people, and you have the same exact number of dentists, 180,000. So, the challenge I speak of is how does a society that’s becoming – emerging rapidly into westernized dentistry, how do we get healthcare out to all those people?


    Okay, today we’re going to talk about censorship in the dental profession. Is that all right with you? Oh, it looks like you’ve been censored.


    Ruddle uncensored.


    The reps are really good at what’s trending. So, an example, if there’s something new in diagnostics or you name it, there’s a lot of competition in the endodontic field, so if the rep either has the new technology that he’s familiar with or that she’s familiar with, they’re going to be really excited about it, but they’ll also tell you what the competitor is selling and what’s new, and they’ll be able to tell you quite a bit of information. So, they’re very good at trending, they’re very good at knowing what’s going on in your community cause they have their fingers on the pulse.


    The International Federation of Endodontic Association, we were supposed to be there physically, live, during this exact period, but because of COVID and the increasing outbreaks, the whole meeting was cancelled, and so it became an online congress and most people said it was impossible to do it.

    So, I want to acknowledge the Indian Endodontic Society. They had – they threw an army of people behind it. And in conjunction with IFEA and their organization, those two organizations put together this technical event that was very, very difficult to do, but it came off flawlessly.


    And the first is Dr. Shimon Friedman from the University of Toronto and so let’s hear what he’s going to be presenting.


    Ah Shimon, let’s play it for you, baby.


    Hello there. I’m Dr. Shimon Friedman from Toronto, Canada, and I invite you to attend my lecture at AAE21 in a short session with my friend, Dr. Carlos Boveda from Caracas, Venezuela. The session is titled, Contracted Endodontic Cavities for Extended Tooth Survival – Is Less More?


    In your opinion are there situations in which discounts are warranted?


    I might want to do it with certain referrals. So, I’ll do it for that. We didn’t get to family, but yeah, we throw family in there. We throw staff in there, and they get all the stuff for free. So, family, staff, and your best referrals, teaching cases, and then sometimes we would do live demos.


    Today we wanted to discuss practice culture and invite you to take a serious look at the culture you have created in your dental office and assess if it is the culture you want to have. To put it in simple words, the culture of your practice revolves around the morals, outlook, goals, values, attitudes, and customs that are shared by the people you work with.


    And then I also heard you say that just this friendly environment. So, once you get into a school and you go and visit there you can see right away whether or not you might fit in.

    [video ends]


    Those community memories were excellent. They really inspired me, and it needs to inspire you to get out and act in your community.


    Okay, so the fourth side of the triangular pyramid is lifestyle because sometimes you just need to get away from work, maybe get outside, get some exercise, go on a trip, have some fun, laugh a little, maybe even just spend all day relaxing, watching the Olympics. But it’s necessary to do this for balance so you don’t get burned out.

    So, we have taken some time on The Ruddle Show to show you some highlights from our family vacation to Hawaii, we’ve shown you some footage from the gym that my mom designed, and we’ve also shown you some – we’ve shared some stories to give you a little glimpse into our family life through Ruddle Flashback.

    Maybe some of you might remember the winning on the slot machine in Las Vegas or the Christmas tree in the fireplace bonfire or the skill saw accident. And then we’ve also revealed some hidden talents like woodworking, and we’ve had some emotional Show and Tells.


    Yes, and we even popped up at the crack of dawn to go out on a wharf. It’s the oldest wharf on the west coast of the United States and we were out there for a sunrise show. Do you remember that? If not, you better go back and check it out. There were a lot of birds out there on that sandspit over on the yacht side.


    We also saw your workspaces.


    Oh yes, and then we toured where Cliff hangs out so we went through the house and we went out to the office and there was the Histo Lab and my granite table, so if you’re ever in town, you know, you could drop by and probably catch me in one of those three places.


    Okay, well let’s see some highlights from our lifestyle segments.

    [video playing]


    We spent a lot of time with the family, we spent a lot of time together. I’m a big outdoorsman, and I have a passion for wine, as you know, Cliff and Lisette, so much that I bought my own vineyard in Mendoza, Argentina. I’ve learned a lot doing that. So, you know, with all those things I guess the key message here is bringing balance to your life.


    And I was using a saw to dado out slots to put the treads in. The treads are the steps that you get on up to the second level. And I remember perfectly I did not think I was taking a chance, but the saw bound, and it jumped and went across my thumb, so my thumb was just hanging down, it was bleeding. So, I called for Philly, Phyllis, and Phyllis came running and got a towel and off we went to ER.


    When I was going to put a Christmas tree into the fireplace, it might seem stupid to you, but I did, and it was a thing of beauty for about 30 seconds. And long story short, the tree and the house – the tree did burn down; the house was saved.


    And Daniel Nobs said, “Would you like to go across the street and see one of the most famous stadiums in Europe?” And I said, “What would that be?” And he said it was Santiago Bernabéu where Real Madrid plays. They had a whole past, a whole museum about the great games, the great players.


    This picture is of me and Isaac. It’s 10 years ago, and this is on the Great Wall in China, and we were going to train at the Shaolin Temple, and we were going to also rank test, and I tore my ACL one week before the trip.


    And it took me a little bit. I like jumped and then I flopped off, and then I jumped and it would be like blah, and then I’d like go off again, but finally I like got myself together and then I went on the board and it was definitely really cool cause we saw some turtles and stuff, but then, yeah, I remember I had no idea that my grandparents were going to be going kayaking, so when I saw then, their unison was like undeniable, their communication, they were all going at the same time. It was really cool to see that.


    I was saying well I could last for awhile with popcorn. A bowl of popcorn a day will keep the doctor away. Good roughage.


    We’re going to get started on that in a second. But I would recommend, you know, in your location, that you get out to some special spot where for a sunrise. It’s a great way to start the day and it’s a great way to start the rest of your life and for us it’s a great way to start to get inspired.


    So, let’s get inspired here okay. We’ll see you on the set soon.

    [video ends]


    All right, so a lot of what we’ve talked about so far is included in the main body of our shows, but we also have openers and closes that have become fan favorites, and for the openers a lot of times we might talk about a news article or maybe sports or just something that’s interesting to us. So, some things that we have covered in our openers are CBD in dentistry, Ingles’ new textbook, dentistry in the movies, summiting Mount Everest in our book review of Into Thin Air, teledentistry, music therapy, power outages, rivalries, wildlife, astrology, documentation and creativity, to just name a few of them.


    Well, the openers have always been fun for me, but it’s not without effort. I mean you gave me some assignments, and I find myself permanently not available for a couple days just to prep out for that five-minute opener. Anyway, we’ve also done some really cool closes, I think, and I think you liked them. I mean some of you were commenting on them, all three of them, right? No, we get a lot of comments on different aspects. Now the closes aren’t really people commenting on them, but we did the Good News/Bad News Dilemma. We did Superlatives, What Phyllis Thinks, and you know she has a lot to say about music and books, and I don’t know what all she does – movies, exercise.




    Camping, oh yeah, she’s a prolific camper, Big Sur comes to mind. Yes, I did some Ruddle Rants. Sometimes it’s good to clear my mind of some of the nuisance thinking and some of the misinformation in the marketplace. I won’t do one now. We did Ruddle One-Liners, and we went and did Flashbacks, Show and Tell. Then I think we did some Demotivators. I liked the Demotivators a lot because I like how they’re so funny but yet there’s a message inside. So, I hope you’re getting – when we throw Demotivators we’re not trying to kill you; we’re trying to get you to laugh a little bit and think about things in a different context.


    And because we think they’re hilarious, so hopefully you do too.


    Yeah, in fact I might send out some demotivators after this show to some of you out there just to get you.


    All right, well let’s see some highlights from our openers and closes.



    [video playing]


    First, I know what I did this weekend, and you probably did the same was watch a lot of sport.


    This was John’s, it turned out, because he passed away in 2017, but this was his last meeting he ever attended, and so that’s a group picture of us.


    Well and here’s the book. It’s called Into Thin Air, and it’s by John Krakauer. Maybe some of you have heard of it. Climbing Mount Everest is not so different than being an endodontist because if you think about it, you’re going to a place where very few people have been before, whether it be the summit of a mountain or inside the canal of a tooth that’s never had endodontics before. You need the latest technology, you need a lot of training, so –


    The view you’re going to see shortly is me on my balcony about 20 yards from the chopper. Well actually the helicopter pilot told the guys on the ground to go get ahold of that little white-haired guy up there on that balcony because dammit, there could be a problem.


    I guess your house was in a possible crash zone.


    The biggest rivalry in my day was Frank Weine from Chicago and Herb Schilder from Boston.


    I don’t know if you can guess what movie this is from, but they are Neo and Trinity from The Matrix. So, do you remember anything about that, where it was taken?


    It was –


    Oh, I remember.








    San Diego.


    At the moment we are here on the second day of the seminar. It’s Saturday morning, around – a little bit before 8:00. I’m preparing for a lunch later on and Rik’s relaxing himself a little bit by playing his guitar.


    Documentaries, I love any of the musician documentaries, like the history of the Go-Go’s or the Bee Gees or Gordon Lightfoot, and they’re fascinating to me how hard and how long they worked to get to where they got.


    Well, the best advice I heard this year has to do with people that I’ve lost, and I remember very clearly my dad’s comment, “Plan for the future but live every day as if it were your last.” So, that’s pretty good advice cause nobody promises you tomorrow, so like have a lot of fun today, get it done.


    Attitudes are contagious. Mine might kill you.


    Oh my, balancing this work and life is really important, and then it helps your attitude. When we have a great attitude it’s infectious.


    And yeah, and apparently a bad attitude is also infectious.


    Bad attitude, you’re going to take the whole staff down.


    Okay, so we’re going to close our show today with another Ruddle Rant. Okay, don’t start it yet. And we have this little like timer here that’s a minute, so he gets to talk until it runs out, and then he gets cut off. Leaving Bacteria Behind.


    Oh, that makes me really angry.


    After all is said and done, more is said than done.


    Well, that’s probably one of my favorites. I’m in R&D. I just think of so many meetings. You might have that Zoom meeting for one month and it might just keep going repeat, repeat, and you’re talking and all of a sudden, I’ll look at another clinician and we’ll go we’ve been over this like 10 times. So, let’s quit talking about it; let’s do it.

    [video ends]


    Well one segment we did that was one of our favorites was the one we did on AI. I also personally like cognitive dissonance and culture a lot, but this one on AI was very good and we talked about how AI was used in dentistry, and most of the time it’s used for like diagnosis, like detecting caries or fractures. But we also thought of a way it could be used in education.


    Oh right, that’s where they took a Holocaust survivor and through algorithms and AI, they have him interacting – well let’s take a look.


    They made an interactive hologram, yeah.




    So, let’s see this clip.

    And so, we were thinking like what if this – like how could this be applied to dental education, like what – like, for example, what if we made a hologram of you and then you – any dental student could buy the software and you could be their private tutor. They could ask you questions.


    Well, I’d sure get a lot of bull----.


    I mean that would be interesting. Like imagine if you – if they had done this with someone like Dr. Herb Schilder, and now you could have a conversation with him. And say they – he is able to extrapolate and deep learn and all that. You could even ask him about things like what he thinks about GentleWave or something, and he’d be able to give an intelligent answer.


    That company, Conscience Aware – or no, I’m sorry, Conscience Display, that’s the company that combined with USC. They said that these holograms can learn, and they can learn way into the future. So, you could take a new problem that happened – not a problem or a challenge or something, or technology, and you could ask Dr. Herb Schilder who’s been – passed away for many years now. You could ask him a question about future disinfection technologies. You could ask him about regenerative endodontics.

    You could ask him what he thinks about some new technique he’s never heard of, but he would have learned too, see, so he would be able to answer it. So, I thought that was kind of in perpetuity to be able to tap into some of the great ones and keep hearing that perspective. It would be a great influence, wouldn’t it?


    Yeah, it would be really a neat thing if this could be applied to education, you know, not even just in dentistry, but in education in – on any field that you’re studying.

    [video ends]


    Okay, so we hope you’ve enjoyed this little celebration of our first 50 shows. It’s been quite an experience, but I think we’ve learned a lot.


    We have learned a lot. And I hope the shows are bringing you some inspiration, that you’re learning a little bit, and maybe even laughing from time to time. Those are good ingredients. For me personally, I want to thank you. You have carved out some amazing scripts that we use from week to week, and your effort to do that – deep acknowledgment, and fun working with you.

    And then, of course, her son, Isaac, my grandkid, he’s the shooter, and he’s fun to work with and he makes us laugh a lot. In fact, sometimes when we start these segments there’s a little bit too much laughing, I’m told, but it’s because of the joke we had first.

    I want to acknowledge Philly. Phyllis is the wind beneath all of our wings. She keeps us in elevated form, so our trajectory is true, right to the finish. And then Lori is the glue that holds is altogether, and as producer, I want to really acknowledge her. She’s a great kid to work with, and so I get to work with my family. You can see it’s not so bad.


    Yeah, it is a lot of work. Sometimes we do put in a lot of time trying to create high quality, relevant shows, but we do have fun also, so we’d like to leave you with this little clip that shows some behind the scenes footage about how much fun we actually have on The Ruddle Show.

    [video playing]


    …Now moving right along in this fabulous presentation – well we have a collapse here…


    …Is this going to work?...


    [cross-talk] We don’t want this to get over here. That’s a problem.


    Oh okay.


    …And you’ll come back and say five…


    …And they’re learning to do endodontics, but they’re also going to do restorative procedures. So, let’s cross this one off your list. Restart now, park, pick a time, remind me tomorrow. Well, I’m going to have you remind me tomorrow, but maybe we should restart now. What would that do?


    Oh no, it restarts the computer…


    …And we did SEM’s and we showed clean root canal systems as we did it in that era. Thank you very much.


    Okay, good job.




    …So, and it was never the same again, and I’m like why are they using that as an example? Why don’t they use Kevin Durant as an example. That just happened.




    I know, but I guess they don’t want to say he was never the same…


    So, I think what we should probably – you see that, don’t you?


    It’s – we’re using invisible ink today.


    That was probably Phyllis’ answer…


    …You might just want to keep it on the first count cause I’m going to look over.


    I know, I know. I – I know how to do my job!




    …3-2-1 action…


    …Well, the show’s meant a lot –


    Oh wait, okay, I actually start. I say, “Okay.”


    Well, we’re getting a whole season of bloopers.


    It’s my turn…


    …Okay, you’re going to be red if you don’t –


    You’re so red.


    You’re all, I’m red…




    …Welcome to the machine…


    …And that’s a wrap. Okay, dad…


    …Well, I’m trying to make it interesting –


    There was only one space [sounds like] –


    Because we talk about frame of reference and it’s interesting to change –


    Don’t make it too interesting.


    You should have a floor camera over here so every now and then I could go, “This is interesting, huh?”


    Oh wow.


    You guys listening? To my floor camera –


    I’m already rolling, so –


    Oh, should I start?...


    … You just say – I’m working on a new file, but what does that really mean? Does that mean you’re like thinking really hard about a file or talking on the phone about a lot? … On the phone all the time?…


    … System shutdown.

    CLOSE: Thank-Yous and Goodbyes


    So, that’s our show for today. We’re going to close out with a little video that’s a tribute to the guests we’ve had on our show. So, thank you to all of our guests and thank you to our viewers and hopefully we have another 50 shows.


    Well, remember, The Ruddle Show is not a secret. Tell your friends.

    [video playing]


    So, what I say is no worries, keep safe, love each other, and give Phyllis and your daughters and your whole family a big hug from us. For now, our hugs will be digital. See you and we love you. Bye… And Wilma wants to say goodbye.


    Bye, we love you. Take care, stay safe.


    Ground yourself in gratitude. I promise you whatever is going on in your life – we don’t have bad days; we have bad moments. Even in the worst days of our life there’s probably something really great that happened before.


    I’m an optimist and an extreme optimist. I believe that one person can change things, and one problem we have in education today is bias and corporate bias influencing the narrative of education and distorting the truth that we talked about earlier. So, I think in the future we have to balance this out better. We need technology, we need innovation, but we also need to have fair non-fraudulent science in education.


    I’m actually very inspired by your passion, so thank you for coming on the show today, and thank you both.


    Thank you, Cliff.


    Thanks, Lisette. Thanks, Terry. We’ll have you back cause you have a lot to give.


    Cliff is my brother because when I have something in my mind, I call him and I ask him what he is thinking about something, and at the end we always, always reach the same results, always, always. So, it’s very nice and John, my friend too, my second brother, I like to talk with you, John, because you make me laugh and you always are in good humor. I remember the session we spent at the plant talking, exchanging, and discussing. This was so nice. So, for me it’s unforgettable memories.


    Well definitely the dental profession is very lucky to have all of you as leaders, so thank you very much for participating in the interview and that was a great interview, thanks.




    Thank you, Lisette. It was really enjoyable. Thanks.


    Thanks, boys. The joy and the beauty of endodontics and the harmony and really get excited in life is about how we see it, how we get ready, like John said, mentally prepare to do it, prepare to win.


    For most of us we don’t need necessarily need it in your tool belt [sounds like]. Don’t get me wrong. I love technology and anything that is present that’s out there or in here that’s going to make my job better, I’m engaged and enthralled. But most of us, rather than buying a tool just need a checkup from the neck up.


    Well, thank you so much for joining us and definitely there is a need for this right now, so we’re grateful to you for thinking about it, thinking of the idea, but then going all – taking all those other steps to actually make it available to everyone. So, thank you very much for joining us.


    It’s been my pleasure. Great to have this time with you both.


    Thanks, Micah. So, you only have so much money; microscope, CBCT? Which could you not live without?


    You need both. You need both.


    Good answer.


    It’s like salt and pepper. You need both.


    So, in your world it’s not an either/or; it’s an and/both.


    Yeah, you need both. You need one for diagnosis and management and then the other one to execute treatment.




    Yeah, that’s it. You need both.


    Shanon, thanks so much.


    My pleasure. Take care, guys.


    Thank you.


    You’re a great guy, and it was a big honor for me to have you one here.


    My pleasure. And stay safe, everyone, and hopefully we’ll be face-to-face in the future, soon.


    Thank you.


    Thank you.


    You said a very – I don’t know if it’s famous. It might have been Yiddish, but I think it was your grandparents that told you, and if you don’t say it, I’m going to say it, so I’m going to give you the chance to say the coaching about life, and then death.


    Okay, tell me what I said cause I –


    You said something about be sure to die early as late as possible.


    Right, the secret to life – the secret to life is to die – what is it? The secret to life – okay, that’s what it is. The secret to life is to die early as late as you can. Is that the, is that the quote? What I said was the secret to life is to die young as late as you can.




    Thanks very much.


    That actually makes a little more sense.


    Thanks, Gary.


    All right, thank you.


    That’s the – that’s the quote. I’m glad we got it right.


    And Cliff is the god of Endo. I hope you know that. Cliff, thanks for doing these little podcasts. I appreciate the opportunity to share a moment with you and hope the viewers got something out of this brief introduction. Watch now for oncoming anti-microbiologic materials. It’s the biggest jump we’ve had in restorative medicine in many years. Thank you.


    And I want to tell you, I mean you’re doing something that’s going to change the way we practice and approach our endodontic treatment internationally. So, for that, we’ll definitely want you back in the future, and stay in touch with me, big guy, because you know how much I think this is going to change the future of endodontics.


    Yes, thank you so much for joining us today and we really do want to follow you on this journey, so we will have you back again.


    All right. Thank you, guys, for having me one and again, if any of your guests have any questions of want to do research themselves, then you know, just feel free to reach out to me at ddscross@gmail.com. Thank you, guys, so much for having me on.


    Thanks, Randy.


    Yeah, thanks.


    Well Nathan, I want to thank you for joining us. I know – you’re a big book, and I really appreciate all of your knowledge, and I guess I’ll read you a little quote that I have. It’s from Aristotle. And it reminds me of your journey from the little kid in China to where you are today. And basically, your journey reminds me of, “We are what we repeatedly do. Excellence then is not an act; it’s a habit.” And for you, you’ve made excellence a habit. Thank you.


    Thank you, sir. Thank you, Lisette.


    Thank you.


    She’s way more than a dentist. She’s an entrepreneur, and one of her enterprises is dentistry, but we wove in the publications, but when she’s publishing it’s helping her in her practice. So, I’m talking about the synergism. When she started inventing because she had curiosity because clinically, she was being challenged by fractures of different kinds, she went after it, and all of a sudden, she’s publishing, she’s inventing.

    So, then there’s the Children’s Clinic, so I want to encourage everybody out there, you don’t have to be – God didn’t put you on this earth to sit chairside in four walls your whole life. You can do a lot. And I’m really proud of Cherilyn. She’s a fabulous clinician. I just found my new dentist.


    Thank you so much for joining us because I actually feel really lucky to have met you and to be able to ask you these questions. I mean it’s a great interview. Thank you very much.


    Oh, thank you. I mean this was really fun, and I have loved your dad for many years and just admired so much all that he’s contributed to dentistry, and also your family and your family unit. It just reminds me so much of the love that we have within our family too. And I think that that is really something to treasure for all of us, so this has been fun. Thank you for asking me to do it.


    Thank you, Cherilyn.
