Here's a podcast that I regularly listen to: dentalcast hosted by Dr. David Dodell. The podcasts are generally aimed at the professional populations (dentists, hygienists etc.) and offer quite a bit of good information. (e.g. Episode 24 -Bisphosphonate Associated Osteonecrosis of the Jaw)
You can subscribe to the podcast in iTunes or go to the website here: Dentalcast
