| Abstract | ||
| The lower third molar is the most teeth failed to erupt in the alveolar process and the surgical extraction of lower third molar is widely carried out in the dental clinic due to pathologic change and prophylactically purpose, the damage of the inferior dental canal can be occurred when the lower third molar located deep and its root is closely to the inferior dental canal, the aim of this study was to investigate the prevalence of the types of impacted lower third molar between male and female and to determine the radiographic relationship of the inferior dental canal to the root apices of different types of the impacted lower third molar using dental panoramic radiograph, eighty (80) panoramic radiographic images ,40 male 40 female aged (18-41) were selected from the pool of data stored in the computer of the digital panoramic machine, the teeth were divided according to the relation to the lower 7th molar (angulation), and the relation of the root apices to the inferior dental canal according to the distance of root apices from the inferior dental canal either far, close , superimposed. The result of this study showed that the mesioangular type of impaction is the most closely positioned to the inferior dental canal , and this may represent an independent risk factor for postoperative paraesthesia, the majority of patients showed the position of the inferior dental canal varies in relation to the root apices of impacted mandibular third with the majority being in adjacent position , The superimposed relation of roots apices of the mesioangular impaction in male was 32% while in female was 46% so the risk of the damage to the mandibular canal in female more than the male during the surgical extraction of lower third molar, this variation should be appreciated by the oral surgeon when undertaking surgical extraction of the impacted mandibular third molars. | ||
