Evaluation of mandibular accessory canals using cone-beam computed tomography(CBCT) a select population of Tabriz in 1393-94

Abstract

The present study aimed at evaluating of Mandibular Accessory Canals Using Cone-beam Computed Tomography (CBCT) a select population of Tabriz in 1393-1394. Methods: A retrospective analysis of 450 successive cone beam CT scans, for patients of both genders was performed. They were exposed at the School of Dentistry, Medical Sciences of Tabriz University. After applying the exclusion criteria (the presence of severe ridge resorption, pre-existing implants, a previously reported history of craniofacial malformations or syndromes, a previous history of trauma or surgery, inadequate image quality and subsequent scans from the same individuals), 450 scans were ultimately included in this study. Results: Of the 450 scans (246 females and 204 males) that qualified for inclusion in this study, accessory canals were identified in 193 cases (42.9%; 111 females and 82 males). Conclusions: A network of accessory canals bringing into communication the inner and outer cortical plates of the jaws was identified. According to these findings, clinicians should carefully assess for the presence of accessory canals prior to any surgical intervention to decrease the risk for complications.
