BACKGROUND Surgical extraction of third molars related to the inferior alveolar nerve can cause paraesthesia. With coronectomy, the full extraction can be achieved without complications or with minimal complications. The present study aimed to compare the amount of eruption and the parameters of edema, interincisal clearance, and pain in coronectomy procedures performed in patient in different age groups and to evaluate the development of endodontic lesion. MATERIAL AND METHODS Seventy-three patients aged 18-55 years were included in the study. The patients were divided into 2 age groups: 18-30 years (n=40) and 31-55 years (n=33). After performing the coronectomy, the roots were left in place. Interincisal opening, percentage of edema, and pain scores were recorded preoperatively and on the 3rd and 7th postoperative days. Panoramic radiographs were taken at 6 months to assess root migration. RESULTS The distance of interincisal opening and the percentage of edema on the 3rd day were lower in the 18-30 age group (P<0.001). In both 2 groups, interincisal opening and percentage of edema on the 7th day were close to the preoperative values (P>0.05). In the 18-30 age group, the pain scores on the 3rd and 7th days were higher (P<0.001). Root migration in the 18-30 age group was 2.50±0.42 mm and 2.26±0.56 mm in the 31-55 age group. No significant difference was found between the 2 groups (P=0.288). There was no endodontic lesion formation detected during the 6-month follow-up. CONCLUSIONS Coronectomy is a practicable approach for mesio-angular impacted third molars in close proximity to inferior alveolar nerve (IAN) in individuals aged 18-55 years old.
背景 与下牙槽神经相关的第三磨牙手术拔除可能导致感觉异常。采用牙冠切除术，可实现完全拔除且无并发症或仅有轻微并发症。本研究旨在比较不同年龄组患者进行牙冠切除术后的萌出量、水肿参数、切牙间隙和疼痛情况，并评估牙髓病变的发展。
材料与方法 本研究纳入了73例年龄在18 - 55岁的患者。患者被分为2个年龄组：18 - 30岁（n = 40）和31 - 55岁（n = 33）。进行牙冠切除术后，将牙根留在原位。术前及术后第3天和第7天记录切牙开口度、水肿百分比和疼痛评分。术后6个月拍摄全景X线片以评估牙根移位情况。
结果 18 - 30岁年龄组术后第3天的切牙开口度距离和水肿百分比更低（P < 0.001）。在两个年龄组中，术后第7天的切牙开口度和水肿百分比均接近术前值（P > 0.05）。18 - 30岁年龄组术后第3天和第7天的疼痛评分更高（P < 0.001）。18 - 30岁年龄组的牙根移位为2.50±0.42 mm，31 - 55岁年龄组为2.26±0.56 mm。两组之间未发现显著差异（P = 0.288）。在6个月的随访期间未检测到牙髓病变形成。
结论 对于18 - 55岁、近下牙槽神经（IAN）的近中阻生第三磨牙，牙冠切除术是一种可行的方法。
