To evaluate the effectiveness of a therapeutic laser in the control of postoperative pain, swelling, and trismus associated with the surgical removal of impacted third molars.
A double-blind, randomized, controlled clinical trial was conducted in 2 groups of 15 patients each undergoing surgical removal of impacted lower third molars under local anesthesia. The experimental group received 4 J/cm(2) of energy density intraorally and extraorally, with a laser with a diode wavelength of 810 nm and output power of 100 mW in a continuous wave. The control group received only standard management. The degree of postoperative pain, swelling, and trismus was registered for both groups.
The experimental group exhibited a lower intensity of postoperative pain, swelling, and trismus than the control group, without significant statistical differences. Patients of both groups required rescue medication; however, the time lapse between the end of the surgery and the administration of the medication was shorter for the control group.
The use of therapeutic laser in the postoperative management of patients having surgical removal of impacted third molars, using the protocol of this study, decreases postoperative pain, swelling, and trismus, without statistically significant differences.
评估治疗性激光在控制与拔除阻生第三磨牙手术相关的术后疼痛、肿胀和牙关紧闭方面的有效性。
进行了一项双盲、随机、对照临床试验，两组各15例患者，均在局部麻醉下接受阻生下颌第三磨牙的拔除手术。实验组在口内和口外接受能量密度为4 J/cm²的照射，使用二极管波长为810 nm、输出功率为100 mW的连续波激光。对照组仅接受标准处理。记录两组术后疼痛、肿胀和牙关紧闭的程度。
实验组术后疼痛、肿胀和牙关紧闭的程度低于对照组，但无显著统计学差异。两组患者均需要使用急救药物；然而，对照组从手术结束到用药的时间间隔更短。
按照本研究方案，在接受阻生第三磨牙拔除手术的患者术后管理中使用治疗性激光，可减轻术后疼痛、肿胀和牙关紧闭，但无统计学显著差异。
