目的:比较涡轮钻劈法和劈冠凿骨法拔除下颌低位阻生智齿的临床效果。方法:选择下颌低位阻生第三磨牙160例,随机分为观察组和对照组各80例。观察组采用高速涡轮钻劈法拔除,对照组采用传统劈冠凿骨法拔除,比较两组操作时间、术后疼痛和局部肿胀程度的差异。结果:观察组操作时间为(17.5±4.2)min,对照组为(27.4±5.4)min,观察组显著短于对照组(P<0.05);两组术后1天、3天、5天疼痛评分和局部肿胀情况比较,均差异显著(P<0.05)。结论:采用高速涡轮钻劈法拔除下颌阻生齿临床效果较好。
OBJECTIVE: To compare the clinical effects of turbomachinery and split crown chisel extraction of mandibular lower impacted wisdom teeth. Methods: 160 cases of mandibular third molar impacted lower jaw were randomly divided into observation group and control group with 80 cases each. The observation group was excised by high-speed turbine drilling and the control group was removed by traditional split crown chisel method. The difference of operation time, postoperative pain and local swelling were compared between the two groups. Results: The operation time in the observation group was (17.5 ± 4.2) min and in the control group (27.4 ± 5.4) min, the observation group was significantly shorter than that in the control group (P <0.05). The pain relief in the observation group was 1 day, 3 days and 5 days Scores and local swelling were significantly different (P <0.05). Conclusion: High-speed turbine drilling split extraction of mandibular impacted teeth clinical effect is better.
