Abstract：
BACKGROUND: Soft tissue anesthesia (STA) following inferior alveolar nerve block (IANB) anesthesia lasts 3-5 h. It is important to reverse STA after treatment to prevent soft tissue injury (STI).
OBJECTIVE: This study evaluated photobiomodulation using a 660 nm diode laser on STA reversal and its impact on STI following IANB anesthesia.
METHODS: A randomized controlled clinical trial was conducted on 32 children, aged 5-8 years, allocated into the test and control groups. Anesthesia was administered; the operative procedure was performed followed by exposure to laser. STA reversal was monitored through lip tapping, current perception threshold (CPT) tests, and paediatric Functional Assessment Battery.
RESULTS: The test group showed significantly faster recovery to normal sensation following exposure to laser than the control group which did not undergo any reversal (p < .0001), with a median time of 115 and 60 min according to lip tapping and CPT tests, respectively. The test group also showed significantly faster recovery to normal function (p = .016). The incidence of STI in the form of redness was significantly higher in the control group (p = .022).
CONCLUSIONS: Photobiomodulation using a 660 nm diode laser can be considered as an efficient approach to minimize STA and STI after dental interventions.

摘要：
背景：下牙槽神经阻滞（IANB）麻醉后的软组织麻醉（STA）持续3-5h。重要的是在治疗后逆转STA以防止软组织损伤（STI）。
目的：本研究评估了使用660nm二极管激光对STA逆转的光生物调节及其对IANB麻醉后STI的影响。
方法：对32名儿童进行了一项随机对照临床试验，5-8岁,分配到测试组和对照组。进行麻醉；进行手术程序，然后暴露于激光。通过轻敲唇监测STA逆转，电流感知阈值（CPT）测试，和儿科功能评估电池。
结果：与未发生任何逆转的对照组相比，暴露于激光后，测试组显示出明显更快的恢复正常感觉（p<0.0001），根据嘴唇敲击和CPT测试，中位时间为115和60分钟，分别。测试组还显示显著更快地恢复至正常功能(p=.016)。红肿形式的STI的发生率在对照组中显著较高(p=0.022)。
结论：使用660nm二极管激光进行光生物调节可以被认为是在牙科干预后最大程度地减少STA和STI的有效方法。
