The purpose of this study was to evaluate the gubernacular tract in unerupted supernumerary teeth by cone beam computed tomography. Sixty-four unerupted su-pernumerary teeth were selected from 44 patients (21 females, 23 males, 12-68 years). Gubernacu-lar tract characteristics were evaluated in five dif-ferent groups: No alteration, bending of gubernac-ular tract, contraction of gubernacular tract, oblite-rations of gubernacular tract, difference between erupted direction. Unerupted supernumerary teeth were classified according to their position. The presence and characteristics of the gubernacular tract in the supernumerary teeth were evaluated by cone beam computed tomography.In our study, the frequency of the gubernacular tract was found to be 31.7%. There was no signifi-cant difference between the presence of gubernac-ular tract and gender, age and gubernacular tract characteristics. It was found that gubernaculartract characteristics did not change according to gender, quadrant, age and unerupted positions. Cone beam computed tomography is an efficient method for the evaluation of the gubernacular tract in unerupted supernumerary teeth. Conducting these studies in larger populations will provide more detailed information about the prognosis of impacted supernumerary teeth. ER -
