The present study aimed to examine the extraction of impacted mandibular third molars by using rotatory and piezosurgery equipment. Twenty-five patients of both genders who required surgery to remove their third molars were split into two groups (control group and research group). In the surgical extraction of the impacted mandibular third molar, in the study group, a piezotome was used to remove the bone, while in the control group, a bur was used. Patients' acceptance of bone cutting, the length of the operation, discomfort and bleeding during the procedure, postoperative pain, swelling, trismus, and wound healing were evaluated. A statistically insignificant difference was observed for age and difficulty index. The intraoperative bleeding was similar in both groups. Both the groups tolerated the bone cutting well, with slightly better values for the piezo group. Based on Pederson's difficulty index, the scores of difficulty of extraction of the impacted tooth were measured between the groups. The slight difficulty was observed in 9 (36%) each in the study group and control group. The moderate difficulty in 14 (56%) of control group and 15 (60%) of study group. Severe difficulty was found among 2 (8%) in the control group and 1 (4%) in the study group. The difference was not significant ( > 0.05). Intraoral bleeding was moderately seen in 25 in both groups. Among the study and control groups respectively no intraoperative pain was seen in 14 and 16, mild intraoperative pain in 11 and 7, and moderate intraoperative pain in 0 and 2. Among group I and II acceptance to bone cutting was comfortably seen in 24 and 23, bearable in 1 and 2 respectively. The difference was not significant ( > 0.05). Piezosurgery and bur were comparable in evaluating patient acceptance, intraoperative duration, intraoperative bleeding and pain, postoperative pain, edema, trismus, and wound healing.
本研究旨在探讨使用旋转设备和超声骨刀设备拔除下颌阻生第三磨牙的情况。25例需要手术拔除第三磨牙的患者被分为两组（对照组和研究组）。在拔除下颌阻生第三磨牙的手术中，研究组使用超声骨刀去除骨组织，而对照组使用牙钻。评估了患者对切骨的接受程度、手术时间、术中不适和出血情况、术后疼痛、肿胀、张口受限以及伤口愈合情况。在年龄和难度指数方面观察到无统计学意义的差异。两组术中出血情况相似。两组对切骨的耐受性都较好，超声骨刀组的值略高。根据佩德森难度指数，测量了两组中阻生牙拔除的难度评分。研究组和对照组各有9例（36%）存在轻度困难。对照组14例（56%）和研究组15例（60%）存在中度困难。对照组2例（8%）和研究组1例（4%）存在重度困难。差异无统计学意义（>0.05）。两组均有25例出现中度口腔内出血。研究组和对照组分别有14例和16例术中无疼痛，11例和7例有轻度术中疼痛，0例和2例有中度术中疼痛。在第一组和第二组中，分别有24例和23例对切骨的接受程度为舒适，1例和2例为可忍受。差异无统计学意义（>0.05）。在评估患者接受程度、术中持续时间、术中出血和疼痛、术后疼痛、水肿、张口受限以及伤口愈合方面，超声骨刀和牙钻相当。
