| Knowledge on internal dental morphology is extremely important to the correct execution of the treatment and modeling of root canals. The aim of the present study was to analyze, "in vitro", the configuration of the canal system in the mesial root of 180 maxillary first molars obtained from a Brazilian sample. The teeth diaphanized in order to confirm the presence of the MB2 canal and to determine the internal anatomy. Only in 41 % of the teeth the orifice of MB2 canal emerged from the pulp chamber floor. Among teeth two apical foramina were found in 23.3 %, a single apical foramen was observed in 15,5 % and three apical foramina were present in 2,2 %. Considering the hole sample, the MB2 canal was observed in 65.4 %, merged with the MB1 or branching from... |

| The aim of this study was to evaluate, by the use of clinical and radiographic records, the prevalence of internal resorption in anterior permanent teeth of patients from the Clinic of Specialization in Endodontics of Federal University of Pernambuco, Brazil; related to the period of September of 2001 to June of 2007. 888 medical records from the archives of the clinic were analyzed. Among them 232 referred to anterior teeth. The presence and the location of the resorption were radiographically observed. The obtained results verified that the internal resorption was prevalent in 2.16% of the cases, with 0.86% located in coronal region, 0.44% in root region and 0.86% in both regions. We concluded that, despite of being a pathology of low incidence, the... |

| The aim of this study was to investigate and classify the internal morphology of the mesiobuccal root of upper first permanent molar, using the cone beam computed tomography. A total of 60 first permanent molars, not healthy and with intact pulp cavity, belonging to the Postgraduate dentistry bank, underwent the computed tomography. Axial images of each tooth were analyzed, and results showed that according to the number of conduits, 21 specimens (35%) had single conduit and 39 exhibited two conduits (65%). In reference to the types of internal configuration most commonly found according to Vertucci classification; type I (single channel that extends from the pulp chamber to the apex) was the most frequent (35%), followed by type II (two separate canals... |
