One of the age old questions of endodontic treatment is “Can a complex root canal system be adequately cleaned to eliminate endodontic disease and definitively prevent disease in the future?”

In this interactive panel discussion, Drs. Barrington, Pannkuk and others will discuss actual cleared root sections with complex apical anatomy and then highlight treated clinical cases. The interactive webinar will include participation of leading endodontic program directors, their residents, and PDL subscribed registrants.

This is one of our annual webinars offered at no charge to further understanding of endodontic clinical science and stimulate thoughtful clinical discussion of the most important current issues of dental practice. This is sure to be a very popular webinar with lively discussion so register early.
