Avaliação da percepção de cirurgiões dentistas na avaliação imaginológica de terceiros molares retidos e estruturas adjacentes

Abstract

Oral surgeries of impacted third molar tooth, are frequent. Under these circumstances, the analysis of radiography panoramic previously effectuated has the purpose to visualize the position and the interactions between the tooth and its surroundings structures, minimizing possible complications during and after the surgical procedures, as communication between mouth and maxillary sinus to the lower alveolar nerve. In situations that are high risk to important structures injuries, the coronectomy can be recommended as an alternative solution. Therefore, the objective of this paper was, by means of a objective questionnaire, to verify surgeons` knowledge about radiographic signs which could indicate proximity between the mandibular canal and the lower third molars, or between maxillary sinus and upper third molars, or even signs that may indicate external resorption of the second lower molar caused by intimate contact of the impacted lower third molar. So, an online inquiry was made to the dentists with questions about panoramic radiographs analysis. Based on this data, it was concluded that most of this dentists have the knowledge to evaluate radiographic signs of proximity between third molar and inferior nerve, then, with the results about the coronectomy it was possible to affirm that the dentist has a little knowledge about it, and the most fear related to the technique was the surgery re-intervencion to remove the root, that didn't prove itself as a negative thing in literature findings. This study could presume radiographics signs of external root resorption coming from the dentist result evaluation.
