This study was conducted to compare two different techniques used in odontectomy of impacted mandibular third molar; the modified lingual split technique and the conventional buccal technique as regarding the duration of surgery as well as the incidence of postoperative sequelae such as pain, edema, and trismus. This study was carried out on thirty adult male patients having class II, position B mesioangular impacted mandibular third molar scheduled for removal, the cases were divided into two equal groups. Group one using the conventional buccal technique and group two using the modified lingual split technique. Pain was categorized into a three grade scale according to the dose of the analgesic taken by the patients postoperatively. The degree of trismus was calculated by measuring the interincisal distance when the mouth was opened at a maximum using a graduated caliper both preoperatively and postoperatively. Edema was measured linearly using a tape between different predetermined facial anatomical landmarks in different planes. All measurements were carried out immediately before surgery and after one, two and seven days postoperatively. The collected data were tabulated and were statistically analyzed. There was a significant difference between the two techniques as regarding the duration of surgery in favour of the modified lingual split technique, with a mean of 36.3 minutes, in group two against a mean of 54.3 minutes in group I. As regarding pain there was no significant difference in the first and the second postoperative days, while there was a significant difference in favour of the modified lingual split bone technique in the seventh postoperative day. Trismus and edema were comparable in both groups.
本研究旨在比较在下颌阻生第三磨牙拔除术中使用的两种不同技术；改良舌侧劈开技术和传统颊侧技术，涉及手术时间以及术后后遗症如疼痛、水肿和牙关紧闭的发生率。本研究对30例计划拔除II类、B位近中阻生下颌第三磨牙的成年男性患者进行，病例分为两组，每组人数相等。第一组采用传统颊侧技术，第二组采用改良舌侧劈开技术。根据患者术后服用镇痛药的剂量，将疼痛分为三级。牙关紧闭程度通过术前和术后使用分度卡尺测量最大张口时的切牙间距离来计算。水肿通过在不同平面上不同预定面部解剖标志之间使用卷尺进行线性测量。所有测量均在手术前以及术后1天、2天和7天进行。收集的数据制成表格并进行统计学分析。在手术时间方面，两种技术之间存在显著差异，改良舌侧劈开技术更具优势，第二组平均手术时间为36.3分钟，而第一组平均为54.3分钟。在疼痛方面，术后第一天和第二天没有显著差异，而在术后第七天，改良舌侧劈开技术更具优势。两组的牙关紧闭和水肿情况相当。
