Bio-Ceramic Sealer Extrusion Inside Sinus Tract Mimicking Root Perforation or Root Resorption: A Case Report.

This report shows atypical sealer extrusion of permanent mandibular left first molar (tooth #19) after nonsurgical root canal treatment which is mimicking root perforation or root resorption. The chief complain was slight discomfort with round opening next to the tooth. Depends on the clinical and radiographical finding, tooth #19 was diagnosed as necrotic pulp with chronic apical abscess. Nonsurgical root canal treatment was provided using ProTaper gold (Dentsply Tulsa Dental, Tulsa, OK, USA) to size F3. 4 canals were located (2 mesial canals and 2 Distal canals). The tooth was obturated with single cone and Calcium Silicate-based Bioceramic Root Canal Sealer (CeraSeal). The sealer was extruded which looks like root perforation or root resorption. Finally, the tooth was crowned with single crown The patient had no symptoms, no periodontal pocket, no mobility after 3 years. The sealer can extrude not only in the apical area but also it may fill and follow the trac of sinus tract. However, it doesn’t affect the success rate of root canal treatment with proper cleaning and shaping, 3-dimentional obturation, and a good crown. [ABSTRACT FROM AUTHOR]
