Comparative evaluation of apical micro leakage in root canals obturated with different bio ceramic sealers

Apical microleakage remains a major cause of endodontic failure, emphasizing the need for root canal sealers with superior sealing ability. This in vitro study comparatively evaluated apical microleakage in 200 single-rooted teeth obturated using BioRoot RCS and Meta CeraSeal bioceramic sealers. Standardized canal preparation and obturation were performed and apical microleakage was assessed using a dye penetration method under stereomicroscopic evaluation. Statistical analysis revealed no significant difference in mean apical microleakage between the two groups (p > 0.05), indicating comparable sealing performance. This study advances current knowledge by demonstrating that both BioRoot RCS and Meta CeraSeal provide equally effective apical sealing, supporting evidence-based selection of bioceramic sealers in clinical endodontics.
