The value of therapeutic ultrasound (US) for reducing inflammation was tested in a double-blind controlled study in 150 patients following surgical removal of impacted lower third molars. Facial swelling, trismus, pain and serum C-reactive protein (CRP) were significantly reduced in the US-treated groups and in a placebo group ('mock' US) compared with an untreated control group. The majority of the anti-inflammatory activity was attributable to the placebo effect, and the highest intensity of US (1.5 W.cm-2) was consistently less beneficial than the lower intensities (0.1 and 0.5 W.cm-2) and the mock US.
在一项双盲对照研究中,对150例拔除下颌阻生第三磨牙的患者进行试验,以检验治疗性超声(US)减轻炎症的效果。与未治疗的对照组相比,接受超声治疗的组和安慰剂组(“模拟”超声)的面部肿胀、牙关紧闭、疼痛及血清C反应蛋白(CRP)均显著减轻。大部分抗炎活性归因于安慰剂效应,而且超声最高强度(1.5W/cm²)的疗效始终低于较低强度(0.1和0.5W/cm²)以及模拟超声。
