| The lingula of the mandible is a bone projection that limits medially the mandibular foramen, which is the region where the inferior alveolar neurovascular bundle penetrates. The lingula is an important anatomical landmark used in maxillofacial surgeries and to block the inferior alveolar nerve. The aim of this study was to analyze the different types of lingula found in mandibles of Brazilian individuals, considering aspects such as gender and race. One hundred thirty-two macerated mandibles of Brazilian adult individuals of both sexes, black and white skin colors, were used. The lingula was classified into four types: triangular, truncated, nodular and assimilated. The data were analyzed using Chi-square test and Fisher's exact test. The truncated shape... |

| The presence of the Accessory Foramina of the Mandibular Ramus (AFMR) may be related to anaesthetic failures in the inferior alveolar nerve block and complications in the ramus surgeries. The purpose of the present investigation was to determine the occurrence of the AFMR in adults and, when present, measure its distance to the Mandibular Foramen (MF), to the Mandibular Lingula (ML) and to the posterior margin of the mandibular ramus (PM), comparing data obtained in both sides of the mandible. Thirty dry human mandibles were selected to the present study. The AFMR was considered as every foramina identified between the MF and the PM. When present, its distance to the MF, to the ML and to the PM was measured. The AFMR was identified in 15 of the 30 examined... |

| Paralysis of the mental nerve is one of the principal complications of surgery of the mandibular canal and mental foramen region. Therefore, identification of mental foramen is important for dental surgeons in nerve block and surgical procedures like apico curettage of mandibular premolars, amalgam filling, peridental surgery etc. to avoid injury to neurovascular bundle. Accessory mental foramina tend to exist in the apical area of the first molar and posterior or inferior area of the mental foramen. The accessory branches of the mandibular canal showed common characteristics in the course of gently sloping posterosuperior direction in the buccal surface area. Verification of the existence of accessory mental foramina would prevent accessory nerve injury... |

| The purpose of this study was to evaluate the newly formed bone, comparing two different carriers for rhBMP-2, using the decortication and nondecorticatication surgical technique in Wistar rat mandibles, evaluated by radiographic densitometry method. It was used fifty six animals according to specific treatment, which were sacrificed after 3 and 6 weeks after this. It was concluded that the decortication surgical technique was able to optimize the osteoinduction properties of the rhBMP-2, independently of the material carrier used and the period of time, according to radiographic densitometry technique. |

| The angle of mandible is formed by the tangent line joining the posterior margin of the ramus and the base of the mandible. The angle of mandible has population-specific characteristics therefore; it is imperative to the field of forensic anthropology for age and sex determination. Literary reports regarding the use of the angle of mandible for age and sex determination vary, as some studies support it, while other studies have documented inefficiencies. Therefore, the aim of this investigation was to document the morphometry of the angle of mandible and to determine if a correlation between the angle of mandible, age and sex exists. Sixty four digital panoramic radiographs (n=128) of individuals between 16-30 years were morphometrically analysed using the... |

| The aim of this study was to correlate the morphodigital characteristics of the trabecular mandibular bone, in this way, it is possible to observe osteoporosis clue in patients of both sex, using panoramic radiograph for analysis. The results of this study showed statistical difference between men and women considering the bone trabecular measures (p<0.05), but it was not found statistical difference between the sides in each analyzed group (p>0.05). Male group presented a more strongly trabecular and complex bone than the female group, this finding is important index to osteoporotic risk, being possible to affirm that the male bone is less probable to suffer a osteoporotic fracture |

| 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... |

| Loth & Henneberg (1996) described a simple morphological feature for sex determination by observing the flexure of the posterior margin of the mandibular ramus, at the level of the plane occlusal. The purpose of this study is to analyze the level of agreement for determining the sex by observing the parameters described by Loth and Henneberg, in ortopantomography of totally dentate Chilean young adults. This study is based on 188 files of ortopantomography acquired from the Department of Radiology of the Dental School of Universidad de Talca, Chile. In brief, our studies indicated that in the ortopantomography of females 63.25% (62-64.5%) was correctly sexed, whereas the prediction accuracy was only 48.25% (46.550%) for men. The success... |

| Morphological variation of the ramus mandibulae of wild Sus scrofa was described and correlated to sex and age differences. Young forms (n=27, 15 males, 12 females) and adults (n=23, 13 males, 10 females) were analyzed through Geometric Morphometrics (2-D) to assess differences between groups. We found significant differences between age- and sex-related shape variations at ramus mandibulae level. Young wild boars present bulky angular process with backward oriented coronoid process, while adults show slender jaw vertical ramus, and orthogonally oriented coronoid process. The ramus mandibulae in female wild boars is more robust and bulky than in males. The morphological changes between young and adult forms are related to alterations in the osteo-muscular... |
