"A step-by-step guide to predictable results"”. This webinar is organised with the support of the Hellenic Association of Endodontists. Attendees will be credited 1,5 CE credits (MEEO).

Abstract
Retreatment in endodontics is among the most demanding and stressful challenges in everyday clinical practice. Failed primary treatments, persistent symptoms, radiographic findings, and technical difficulties often generate uncertainty and hesitation for the practicing clinician.
In this webinar, we will explore why endodontic treatments fail, how to identify critical errors, and—most importantly—how to correct them in a systematic and predictable manner. Through clinical cases, radiographs, and practical tips, step-by-step protocols will be presented for the safe removal of previous filling materials, identification of missed anatomy, effective cleaning, and proper reshaping of the root canal system.
This webinar is aimed at general dentists and early-career endodontists who wish to approach retreatment cases with greater confidence, a clear strategy, and the goal of achieving predictable, long-term clinical outcomes.
