【摘要】 目的:观察埋伏阻生牙拔除术后应用低强度超声照射对缓解疼痛、肿胀、干槽症和促进骨愈合的效果。方法:在门诊患者中,依据曲面断层X线片选择两侧埋伏阻生程度相近者为研究对象,一侧创口术后照射低强度超声,另一侧进行常规处理。应用SPSS10.0软件对患者手术后疼痛、肿胀、干槽症和创口完全骨愈合的情况进行统计学分析。结果:实验组和对照组比较,实验组疼痛4例,对照组16例(P<0.05);实验组肿胀11例,对照组13例(P>0.05);实验组发生干槽症患者0例,对照组4例(P<0.05);实验组创口完全骨愈合35例,对照组21例(P<0.01)。结论:埋伏阻生牙拔除术后应用低强度超声,可以显著缓解术后疼痛,降低干槽症发生率,并促进创口骨愈合,但是对术后肿胀的治疗效果不明显。更多还原

【Abstract】 PURPOSE: To observe the clinical effects of low intensity ultrasound in extraction of totally impacted third molars. METHODS: 40 patients with totally impacted third molars on both sides of the mandible verified by X-ray were selected. After extraction of the teeth , the socket on one side was treated with low intensity ultrasound while the other side underwent no treatment.Statistical analysis was performed with SPSS 10.0 on all patients in form of pain, swelling, dry socket and bone healing. RESULTS: In the experimental group, 4 patients complained of severe pain while 16 patients in the control group(P<0.05). Moderate or severe swelling were not uncommon in both experimental and control groups(P> 0.05);No patients suffered from dry socket in the experimental group and 4 patients suffered from dry socket in the control group(P<0.05);There were 35 patients with complete bone healing in the experimental group while 21 patients with complete bone healing in the control group(P<0.01). CONCLUSIONS: The use of low intensity ultrasound in extraction of totally impacted mandibular third molars reduced the severity of post-operative pain and the incidence dry socket ,and it also stimulated bone healing ,but it showed no effect on relieving post-operative swelling.更多还原
