A cone-beam computed tomographic study in complicated root canal morphology mandibular teeth for endodontic therapy

Abstract

We studied 229 previously obtained CBCT images. It is revealed that a incidence complicated root canal morphology of mandibular teeth (two root and two root canals in mandibular incisors, canines, premolars; C-shaped second molars and premolars) were two root canals in mandibular incisors - 47,2%, first premolars - 20,5%, two root and two root canals in canines - 6,1%, second premolars - 3,5%,C-shaped second molars - 2,9%. The incidence of C-shaped canals in mandibular first premolars were 14,4%, in mandibular second premolars - 0,9%, in second premolars - 2,9%.
