Non-Surgical Retreatment of Maxillary Lateral Incisor with Apical Radiolucency and Coronal Reinforcement

🔍 Clinical Examination: Defective coronal restoration with marginal leakage Noticeable tooth discoloration, indicating compromised pulpal status 🩻 Radiographic Findings: Short obturation of the root canal Periapical radiolucency suggestive of apical periodontitis 🎯 Diagnosis: Previously treated tooth with inadequate obturation and apical pathology 🛠️ Treatment Plan: Non-surgical root canal retreatment to: Eliminate intracanal infection Re-establish apical seal Reinforce coronal structure ⚙️ Clinical Procedure: 1. Access & Caries Removal Complete removal of existing restoration and caries Use of caries detector dye (Nishika) to ensure thorough excavation 2. Retreatment Phase Gutta-percha removal using rotary retreatment files (SuperFile RC) Adjunct use of ultrasonic activation Canal renegotiation to re-establish patency 3. Cleaning & Disinfection Irrigation protocol with sonic activation to enhance penetration and biofilm disruption…
