Obturation Errors: Causes, Consequences, and Prevention in Endodontics.

Abstract

Obturation is a critical phase of endodontic therapy, essential for creating a hermetic seal within the root canal system to prevent bacterial reinfection and ensure treatment longevity. This process, involving biocompatible materials that seal the cleaned and shaped root canal, directly influences the outcome of endodontic treatments. However, various errors—such as underfilling, overfilling, void formation, missed canals, and improper material handling—pose significant risks to treatment success, potentially leading to post-treatment complications like persistent infections and tooth loss.
