دورة مع الدكتور عمر الزهراني - Endodontic retreatment

Root Canal Retreatment in Endodontics is a clinically oriented lecture designed to guide dentists through the diagnosis, decision-making, and technical steps involved in managing failed or persistent endodontic cases. The lecture focuses on understanding the causes of post-endodontic disease, including missed canals, inadequate coronal seal, recurrent caries, procedural mishaps, fractures, and persistent microbial infection.

Participants will learn how to assess whether a case is suitable for non-surgical retreatment, when alternative treatment options should be considered, and how to improve predictability through proper case selection, CBCT interpretation, coronal disassembly, ultrasonic use, conservative access preparation, and identification of missed anatomy. The lecture also emphasizes the importance of evaluating the existing restoration and underlying tooth structure before retreatment to improve long-term prognosis.

Learning Objectives

By the end of this lecture, participants will be able to:

1. Identify the main causes of endodontic treatment failure.

2. Differentiate between cases suitable and unsuitable for non-surgical retreatment.

3. Recognize the role of CBCT in detecting missed canals and complex anatomy.

4. Understand the importance of coronal disassembly in retreatment planning.

5. Apply clinical principles for conservative access and canal location.

6. Appreciate the role of ultrasonics in improving visibility and treatment efficiency.
