Abstract
1800 pre-made cone beam computed tomograms (CBCT) were examined, of which 202 CBCT were selected. It was revealed that a prevalence of three-rooted mandibular first molar was 2,5 %, second molars - 4,5 %. First molar supernumerary root was always distolingual root (radix entomolaris). Second molar supernumerary root was distolingual root in 2,5 % (radix entomolaris), in 2 % mesialbuccal root (radix paramolaris)., The prevalence of double-root in the mandibular first premolar was 2 %, in the second premolar was 1 %, in the mandibular canines was 5 %, the bifurcation was located in the apical and middle third root canals of canine and premolar, which makes endodontic treatment of such teeth as difficult as possible.
