Dental procedures commonly involve the injection of local anesthetic agents, which causes apprehension in patients. The objective of dental practice is to provide painless treatment to the patient. The purpose of this study was to evaluate the effect of Low Level Laser Therapy (LLLT) in reducing the pain due to local anesthetic injection.
A prospective, split-mouth study was conducted on 25 patients. In Condition A, LLLT was administered followed by the administration of a standard local anesthetic agent. Patients' perception of pain with use of LLLT was assessed based on a Visual Analogue Scale (VAS). In Condition B, LLLT was directed to the mucosa but not activated, followed by the administration of local anesthesia. VAS was used to assess the pain level without the use of LLLT.
Comparison between Condition A and Condition B was done. A P value < 0.001 was considered significant, indicating a definite statistical difference between the two conditions.
In our study, we observed that LLLT reduced pain during injection of local anesthesia. Further multi-centric studies with a larger sample size and various modifications in the study design are required.
牙科手术通常需要注射局部麻醉剂，这会使患者产生焦虑情绪。牙科治疗的目标是为患者提供无痛治疗。本研究的目的是评估低强度激光疗法（LLLT）在减轻局部麻醉注射所致疼痛方面的效果。
对25例患者进行了一项前瞻性、双侧对照研究。在A组中，先进行LLLT治疗，然后注射标准局部麻醉剂。根据视觉模拟量表（VAS）评估患者使用LLLT时的疼痛感受。在B组中，将LLLT照射于黏膜但不启动，然后进行局部麻醉。使用VAS评估未使用LLLT时的疼痛程度。
对A组和B组进行了比较。P值<0.001被认为具有显著性，表明两组之间存在明显的统计学差异。
在我们的研究中，我们观察到LLLT可减轻局部麻醉注射时的疼痛。需要进一步开展样本量更大且研究设计有各种改进的多中心研究。
