AIM: The present study aimed at evaluating the role of mental foramen and mandibular canal in gender determination using CBCT.METHODOLOGY: A total number of 73 volumes of CBCT of the mandible was evaluated. Four measurements were used to assess the bucco-lingual and supero-inferior location of mandibular canal and the supero-inferior location of mental foramen was determined using two measurements on both right and left sides of the mandible. Inter and intra-observer variability was analyzed with help of t-test.RESULTS: Good intra-observer and inter-observer agreement was noted with regard to all the six measurements. The mean of all the measurements of mental nerve foramen and mandibular canal was found to be higher in males than females, however, significant difference was noted with regard to Superior Mental foramen (SMeF) and Superior Inferior Alveolar Canal (SMC) (p=0.037, p<0.001 respectively) on the right side and SIAC and Inferior Inferior Alveolar Canal (IIAC), (p=0.015, p=0.046 respectively) on the left side.CONCLUSION: The results of the present study suggest that SMeF, SIAC and IIAC may be used for gender determination. Further, either side of mandible can be used for this purpose. CBCT was found to be a useful modality in this study for sexual dimorphism.

Introducción: Las lesiones iatrogénicas del nervio dentario inferior son complicaciones documentadas de diversos procedimientos quirúrgicos en la mandíbula. Debido a ello se justifica una descripción más detallada con referencias morfométricas de dicho conducto, como así también una correlación con imágenes. Materiales y métodos: Se realizó un estudio descriptivo observacional con una muestra de 44 hemimandíbulas secas y 100 tomografías computadas de mandíbulas de pacientes al azar. Se realizaron mediciones del foramen mandibular y mentoniano con respecto a bordes mandibulares. Se hicieron cortes en la rama y el cuerpo con sus respectivas mediciones. Se utilizaron Tomografías Computadas Cone Beam 3D de 100 pacientes las cuales fueron procesadas por el programa Compudent Navigator 3D®. Utilizando este programa se pudieron realizar las mismas mediciones que en los preparados anatómicos, como así también la reconstrucción del conducto. En una segunda etapa se realizó una correlación entre los valores morfométricos del estudio anatómico y se comparó con los estudios por imágenes (TC con reconstrucción 3D Dental Scan). Resultados: Se expresaron en tablas con diversas variables. Discusión: Los textos clásicos de anatomía y los libros de cirugía de la especialidad describen en detalle el recorrido y las relaciones del CAI, y presentan datos morfométricos pero no lo hacen en poblaciones locales. Como conclusión podemos afirmar que, tomando como punto de partida la anatomía y correlacionándola con la imagenologia, podemos llegar a evitar lesiones del nervio alveolar inferior en el transcurso de diversos procedimientos realizados en la mandíbula. Introduction: Iatrogenic inferior alveolar nerve injuries are documented complications of different surgical procedures in the jaw. It should justify a more detailed description with morphometric references of the duct and a correlation with images. Materials and method: A descriptive observational study with a sample of 44 dry hemijaws and 100 CT scans of patients. Measur-ements of the mandibular foramen and mental foramen with respect to jaw edges were made. Cuts in the branch and body were made with their respective measurements. Cone Beam Computed Tomography 3D (CBCT 3D) of 100 patients were processed by the Compudent Navigator 3D® program. The use of this program permited the same measurements done in the cadaveric jaws and the reconstruction of the duct. In a second stage we performed a correlation between the anatomic morphometric values compared with imaging studies (CT Dental Scan with 3D reconstruction) Results: They were shown in tables with different variables. Discussion: The classic texts of Anatomy and surgery books describe in detail the pathway and relations of the duct, and present morphometric data but not in local population. We may conclude that it is possible to avoid injuries of the inferior alveolar nerve during jaw surgery by considering the anatomy and its correlation with images.

ABSTRACT Objectives To study the radiographic location of the mental foramen and appearance of the inferior alveolar canal and the relationship between image gray values and the clarity of inferior alveolar canal on the digital panoramic images and to evaluate if the histogram equalization of the digital image would improve the visualization of the inferior alveolar canal outline on the digital panoramic images in the mandible. Methods Five hundred digital panoramic images were evaluated by two examiners using a specific inclusion criteria. Only the right side of the mandible was studied. Chi-square analyses were used for comparisons of distributions. Mean and median pixel values were analyzed separately with a one-way analysis of variance. Also, percentages were calculated to report the usefulness of the histogram equalization for visualization of canal. Results Results show variation in location of mental foramen. Most frequent location of the mental foramen was reported as first and second premolar region. Chi-square analysis showed that the frequency of occurrence of the mental foramen was equally probable for any of the three locations. The study did not find significant usefulness of the gray values obtained from the histogram equalization in predicting the clarity of inferior alveolar canal outlines. Clinical significance Knowing the normal relationship and the anatomical variation of the maxillofacial structures for each patient is important for surgical implant treatment planning to avoid future complications. It is also important to be familiar with the advantages and limitations of diagnostic aids available before making treatment planning decisions based on such findings.
