The effect of ameloblastoma and keratocystic odontogenic tumor on the displacement pattern of inferior alveolar canal in CBCT examinations
Background. The inferior alveolar canal should be examined as a significant anatomical landmark, particularly in the posterior body and ramus of the mandible, for dental and surgical procedures. In the present study, the effects of two pathological lesions, ameloblastoma and keratocystic odontogenic...

The inferior alveolar canal should be examined as a significant anatomical landmark, particularly in the posterior body and ramus of the mandible, for dental and surgical procedures. In the present study, the effects of two pathological lesions, ameloblastoma and keratocystic odontogenic tumor, on canal displacement were investigated. Methods. This study had a single-blinded design. Twenty-six patients with lesions in the mandible referred to Imam Reza Hospital, Tabriz, Iran, were studied in two equal groups (13 patients with a histopathological diagnosis of ameloblastoma and 13 with a histopathological diagnosis of odontogenic keratocyst). After confirming the initial incisional biopsy and pathological report, cone beam computed tomography (CBCT) of lesions larger than 3 cm mesiodistaly and those involving the mandibular posterior body and ramus were included in the study. Two maxillofacial surgeons in association with an oral and maxillofacial radiologist examined three points on CBCT images to determine the mandibular canal position relative to the lesions from the lingual and buccal aspects. Results. The results of statistical analyses showed that in ameloblastoma, the inferior alveolar canal had been displaced more buccally in the ramus area (point A) (84.6%) but in the distal region (point C), the displacement was less buccal (41.6%). The canal was displaced buccally in 53.8% of cases at point A and in 46.2% of cases at point C in KOT lesions. Finally chi-squared test did not show any statistically significant differences between these two lesions. Conclusion. The results of this study showed no relationship between these lesions and the displacement of the mandibular canal.http://dentistry.tbzmed.ac.ir/joddd/index.php/joddd/article/view/2729/521Ameloblastomakeratocystic odontogenic tumormandibular canalodontogenic tumors |
