Year-End Q&A Clinical Questions and Ruddle’s Take on 2025

As the holidays approach, many of us take part in festive traditions; in the Opener, Ruddle and Lisette talk about their Christmas caroling cooperation. Then, the two are at the Board, doing a classic clinical Q&A – one important question for each stage of endodontic treatment. After, the questioning continues at the desk; Lisette grills Ruddle on his best and worst of 2025. Season 12 concludes with the 5th Grandkids segment; this time, we meet the youngest, Luca Ostovany, a standout junior tennis competitor with aspirations to play at the professional level. Remember, you saw it here first!
