Abstract

Introduction: A tooth that is unable to erupt completely due to some physiological barrier is called impaction. The extraction of the impacted mandibular 3rd molar is the most frequent procedure in oral surgery. The removal of 3rd molar is associated with complications like damage to the inferior alveolar nerve which causes paresthesia of the lower lip depending upon the severity of the damage. Objectives: This study assesses the diagnostic efficacy of orthopantomograph in predicting the association between mandibular third molar roots and inferior alveolar canal and its juxtaposition with intra-operative surgical findings. Material and methods: This cross-sectional research was conducted in the department of Oral & Maxillofacial Surgery, King Edward Medical University/Mayo Hospital, Lahore, requiring extraction of mandibular third molars surgically. Patients underwent extraction under local anesthesia. The association between M3 and IAC by comparing OPG findings with intra-operative surgical findings was assessed by chi-square analysis. Results: One hundred and twenty patients requiring mandibular third molar extraction were included in the study. The age of the patients involved in the study ranged from 21-70 years. There were 5 cases of nerve injury in the age group of 31-40 and 1 case in each age group of 21-30 and 41-50. Conclusion: The chances of nerve damage also increase significantly when there is more than one radiographic sign present and the tooth is deeply placed in the mandible nearest to the IAN.
下颌第三磨牙与下牙槽神经的骨解剖关系
由于某些生理障碍而不能完全长出的牙齿被称为嵌塞。下颌阻生第三磨牙的拔除是口腔外科中最常见的手术。第三磨牙的移除会带来并发症,比如下牙槽神经的损伤,这会导致下唇感觉异常,这取决于损伤的严重程度。目的:本研究评估骨断层摄影在预测下颌第三磨牙根与下牙槽管之间的关系及其与术中手术结果的对比方面的诊断效果。材料和方法:本横断面研究在拉合尔爱德华国王医科大学/梅奥医院口腔颌面外科进行,需要手术拔除下颌第三磨牙。患者在局部麻醉下进行拔牙。通过比较OPG表现与术中手术表现,采用卡方分析评估M3与IAC的相关性。结果:120例需要拔除下颌第三磨牙的患者被纳入研究。参与研究的患者年龄在21-70岁之间。31 ~ 40岁年龄组神经损伤5例,21 ~ 30岁和41 ~ 50岁各1例。结论:当有多个影像学征象且牙位在下颌最靠近牙槽嵴的位置时,神经损伤的可能性明显增加。
