| Morphological and topographic knowledge of the mandibular canal is of paramount importance during dental procedures in the jaw, as structures that go through this canal must be preserved. The aim of this study was to make a morphologic and morphometrical analysis of the course and relations of the mandibular canal of adult men and women, in two different age groups. The sample was composed of 300 panoramic radiographs divided into 4 groups: Groups F1 and F2: women (ranging between 18-40 years, and over 40 years of age, respectively); Groups M1 and M2:men (ranging between 18-40 years and over 40 years of age, respectively). Seven linear vertical measurements were performed in the radiographs to describe the course of the mandibular canal, and its and... |

| The retromolar foramen allows the passage of the neurovascular bundles that contribute to nutrition and innervation of the pulp and periodontium of the lower teeth. Knowledge of this anatomical variation may prevent complications in the anesthesia and surgical procedures in this area and serve as an anatomical landmark for ethnic identification. The aim of this study was to evaluate the impact of the retromolar foramen in human mandibles of adult Brazilians and discuss the clinical and ethnic related to the presence of this foramen. Were evaluated 222 human mandibles, dry, adults, Brazilians, independent of gender. The evaluation was performed by two examiners who standardized search from a previous anatomical study. The mandibles were analyzed: the... |

| To prevent injury to the inferior alveolar nerve during dental procedures, knowledge of its anatomical location and course of the mandibular canal is imperative. The aim of this study was evaluate the location on panoramic radiographs of the mandibular canal in relation to the apices of the permanent mandibular molars and base mandible, and relate the type of mandibular canal with Angle classes I, II and III. We evaluated 748 panoramic radiographs distributed according to sex and occlusal class (Angle I, II and III) of fully dentate individuals, 1851 age group. The radiographs were divided according to Angle classes based on cephalometric tracing, clinical data from the medical records of each individual and the analysis of of the maxillar and mandibular... |

| This study evaluated the stress distribution based on the canine pillar geometry in human skull, using a finite element analysis. Computed tomography of human skull was used to build a finite element model, which was composed by all bony structures of canine pillar: canine eminence, canine fossa, frontal process of maxilla, glabellum and superciliary arch. A support on the bite contact of maxillary canine tooth and a resultant force of the masticatory muscles was applied in the simulation. Equivalent Von-mises and maximum principal stresses were analyzed along the structures that compose the canine pillar geometry. Von-mises stress presented high stress concentrated at the canine fossa and frontal process of maxilla. Maximum principal stress showed... |

| Craniofacial implants are being increasingly used to treat patients with sequelae of oncological resections, trauma, and congenital deficiencies, among other issues. The aim of this investigation was to establish the minimum and maximum bone dimensions present in the most used places for the insertion of craniofacial implants. A descriptive study was designed analyzing 40 human skulls using cone-beam computed tomography; in the volumetric reconstruction the points most often used in clinical investigations for the insertion of implants were selected, representing the orbital, perinasal, zygomatic bone and periauricular regions, measuring the distance between the cortical bones on the sagittal, axial and coronal planes; comparisons between gender and with... |

| Las mandíbulas encontradas en diferentes regiones del mundo presentan considerables diferencias morfológicas, provocando dudas sobre las alteraciones y las características morfológicas de las mandíbulas humanas. La pluralidad racial y la consecuente mezcla de la población brasileña deben promover cambios morfológicos. Esta investigación analizó y comparó las características morfológicas de 100 mandíbulas humanas brasileñas con las dimensiones de las mandíbulas de individuos australianos, asiáticos, europeos y africanos, usando 13 dimensiones mandibulares definidas por Humphrey et al. (1999). Las diferencias significativas entre los valores medios fueran calculados través del test t student (p<0,05 e 0,01). Hubo diferencias significativas en las... |

| The recognition of emissary foramens is important not only for understanding the regional neurovascular anatomy, but also to distinguish normal from potentially abnormal structures. Thus, the aim of this study was to review the literature on anatomical and clinical aspects of the mastoid, parietal and sphenoid emissary foramens. It was found that the emissary foramen presents importance in clinical practice because it acts as a route of spread of extracranial infection to the intracranial structures and also possible complications in neurosurgery, due to its influence in the performance of techniques such as radiofrequency rhizotomy for treatment of trigeminal neuralgia. The anatomical knowledge of the emissary foramens is important due to variability in... |
