Abstract
Mandibular second molars have many variations in canal configuration. Technical modifications in cleaning, shaping and obturation are required. The purpose of this study was to investigate the root canal anatomy of mandibular second molars. 86 teeth of 85 patients were accessed and evaluated with taking radiographs for working length determination. 27 teeth(31.4%) had C-shaped canals, 43 teeth(50%) had 3 canals, 11 teeth(12.7%) had 4 canals, 5 teeth(5.8%) had 2 canals. Incidence of C-shaped canal was 31.7% in male and 31.1% in female. 30.9% of left mandibular second molar and 31.8% of right mandibular second molar showed C-shaped canals.
