Abstract

The technique of greater palatine nerve block is widely used mainly in oral surgery. The technique's success is the knowledge of anatomy, specifically the location of greater palatine foramen. There are studies tracking it through skulls, but few studies through computed tomography images and any study linking it to the upper molars, which are the main reference for the clinical anesthetic technique. Therefore, the aim of the study is to evaluate the positioning of the greater palatine foramen (GPF) for maxillary molars, alveolar ridge and palatal suture, using cone beam computed tomography of Brazilian adults in order to establish a reference and to contribute in the anesthetic technique of nerve block greater palatine. 100 Cone beam computed tomography (CBCT) of jaw will be evaluated obtained from the archive of images of ICAT Clinic Radiology Department of Stomatology, Bauru School of Dentistry, University of São Paulo. The pictures must be of patients with the 1st, 2nd and 3rd molar or not erupted, and age above 18 years. It will be used the reconstruction axial in the depth of the teeth to be drawn five tangent lines to the points of contacts of the molars, parallel to each other. The tangents are superimposed on the depth of the GPF and its position is classified. Also, be measured the diameter of the GPF and the presence of possible anatomical variations.
