Evaluation of the morphology and anatomy of mandib ular canal in panoramic radiography of patients over 25 years - old (Kerman-2008)

Background and Aim: Neurovascular bundle mandibular canal is one of the most important landmarks in mandible. It is necessary to know complete understanding of its topography and variations. The aim of this study was to assessment of anatomy of mandibular canal in panoramic view. Materials & Methods: In this Cross-Sectional study 394 panoramic view of patients with age 25-53 years old were selected. A data sheet containing age, sex, length and width of mandibular canal and distance of it from mandibular border line was completed. T test and Pearson and SPSS 15 soft- ware used to analyze the data. Results: The mean age was 34.59±6.79 years. The length and the width of mandibular canal were 77.4±3.8mm respectively. The distance between mandibular canal and borderline of mandible was 13.9 mm. there was significant differences between mental foramen to borderline of mandible. There was also significant correlation between age and sex and width of mandibular except second molar furcation area. Conclusion: According to these finding all dentists consider their patientsʹ panoramic view much more carefully to avoid unwanted neurovascular bundle injuries.
