The aim of our study was to evaluate and compare pain perception following photobiomodulation (PBM), topical anesthesia, precooling of the injection site, and vibration during administration of local anesthesia injection in pediatric patients aged 6-13 years.
In this split-mouth study, a total of 120 patients between the age group of 6 and 13 years were selected and randomly divided into three equal groups with 40 subjects in each. Pain was assessed using visual analog scale (VAS) and the Wong-Baker Faces Pain Rating Scale after the administration of local anesthesia. Behavior during the procedure was assessed using the Face, Legs, Activity, Cry, Consolability (FLACC) scale filled by the operator. Pulse rate was recorded before and during the administration of local anesthesia using pulse oximeter. After the procedure, patient compliance was also recorded using validated questionnaire. The level of significance was set at < 0.05.
The study showed PBM exhibited the lowest mean scores of anxiety/pain using VAS, Wong-Baker Faces Pain Rating Scale, FLACC scale and pulse rate as compared to precooling, vibration, and topical anesthesia. The differences in pain scores recorded were found to be statistically significant. Children were not anxious about the PBM method and exhibited good compliance ( < 0.001).
Photobiomodulation (PBM) was found to be effective means of reducing injection pain, demonstrating much better efficacy than other tested methods.
Photobiomodulation (PBM) can be used effectively to better manage procedures that patients frequently find painful without the need for prescription drugs, which frequently have several side effects.

本研究旨在评估和比较6至13岁儿科患者在局部麻醉注射过程中，光生物调节（PBM）、表面麻醉、注射部位预冷以及振动后的疼痛感知情况。
在这项双侧对照研究中，共选取了120名年龄在6至13岁之间的患者，并随机分为三组，每组40名受试者。在局部麻醉给药后，使用视觉模拟量表（VAS）和面部表情疼痛评分量表评估疼痛情况。手术过程中的行为表现由操作人员使用面部、腿部、活动、哭闹、安慰度（FLACC）量表进行评估。使用脉搏血氧仪记录局部麻醉给药前和给药过程中的脉搏率。手术后，还使用经过验证的问卷记录患者的依从性。显著性水平设定为<0.05。
研究表明，与预冷、振动和表面麻醉相比，使用VAS、面部表情疼痛评分量表、FLACC量表和脉搏率评估时，PBM表现出最低的焦虑/疼痛平均得分。记录的疼痛评分差异具有统计学意义。儿童对PBM方法不感到焦虑，且表现出良好的依从性（<0.001）。
发现光生物调节（PBM）是减轻注射疼痛的有效方法，其疗效比其他测试方法好得多。
光生物调节（PBM）可有效用于更好地管理患者常认为痛苦的操作，而无需使用经常有多种副作用的处方药。
