Abstract:
Objective To determine the prevalence of symmetry of C shaped root canal system in mandibular second molars.MethodsA total of 70 madibular second molars with C shaped root canal system to be considered as needing root canal therapy were included in this study,of which 68 contralateral X ray apical films were obtained.The symmetry of the root and the root canal system was analyzed using magnifying glass.ResultsOf the 68 mandibular second molars with C shaped root canal system diagnosed clinically,62 cases with C shaped root canal system bilaterally,with the prevalence 91.18%.ConclusionThe anatomic feature of mandibular molars with C shaped root canal system is complicated,and the prevalence of symmetry is very high,which is in favor of estimating the anatomic feature from contralateral tooth.
