Photobiomodulation (PBM) has gained increasing interest due to its effectiveness in pain reduction in various fields of dentistry. However, the number of studies evaluating the effect of PBM on injection pain in children is very limited. The aim of the study was to evaluate the efficacy of PBM with three different application parameters (doses) + topical anesthesia on reducing injection pain and to compare these results with the placebo PBM + topical anesthesia in children during supraperiosteal anesthesia administration. 160 children were randomly divided into 4 groups, 3 experimental and 1 control, with 40 subjects in each. In the experimental groups, before the anesthesia administration, PBM with a power of 0.3 W was applied for 20, 30 and 40 s in groups 1, 2 and 3, respectively. In group 4, a placebo application of laser was performed. The pain felt during the injection was assessed using the Wong-Baker Faces Pain Rating Scale (PRS), and also the Face, Legs, Activity, Cry, Consolability (FLACC) Scale. Statistical analyses were performed to evaluate the data ( < 0.05). The mean FLACC Scale pain scores were 3.02 ± 2.93, 2.92 ± 2.54, 2.12 ± 1.89 and 1.77 ± 1.90 for the placebo group, and Groups 1, 2, and 3, respectively. Furthermore, the mean PRS scores were 1 ± 1.03, 0.95 ± 0.98, 0.80 ± 0.822 and 0.65 ± 0.921 for the placebo group, and Groups 1, 2 and 3, respectively. The "no pain response" rate was higher in Group 3 as compared to Groups 1, 2, and placebo according to the FLACC Scale and PRS; however, no difference was found between the groups ( = 0.109, = 0.317). Injection pain in children did not differ with placebo and PBM applied with a power of 0.3 W for 20, 30 and 40 s.
光生物调节（PBM）因其在各种牙科领域减轻疼痛的有效性而引起了越来越多的关注。然而，评估 PBM 对儿童注射疼痛影响的研究数量非常有限。本研究旨在评估三种不同应用参数（剂量）+局部麻醉的 PBM 在减轻注射疼痛方面的疗效，并将这些结果与安慰剂 PBM+局部麻醉在儿童行骨膜上麻醉时进行比较。160 名儿童被随机分为 4 组，每组 40 人，其中 3 个实验组，1 个对照组。在实验组中，在麻醉前，1 组应用功率为 0.3W 的 PBM 20s，2 组应用功率为 0.3W 的 PBM 30s，3 组应用功率为 0.3W 的 PBM 40s。第 4 组则行激光假照射。采用 Wong-Baker 面部疼痛评分量表（PRS）和面部、腿部、活动、哭泣、安慰（FLACC）量表评估注射时的疼痛。采用统计学方法对数据进行分析（<0.05）。安慰剂组、1 组、2 组和 3 组的平均 FLACC 量表疼痛评分分别为 3.02±2.93、2.92±2.54、2.12±1.89 和 1.77±1.90。此外，安慰剂组、1 组、2 组和 3 组的平均 PRS 评分分别为 1±1.03、0.95±0.98、0.80±0.822 和 0.65±0.921。根据 FLACC 量表和 PRS，与 1 组、2 组和安慰剂组相比，3 组的“无疼痛反应”率更高；然而，组间无差异（=0.109，=0.317）。与安慰剂和应用功率为 0.3W 的 PBM 行 20、30 和 40s 相比，儿童的注射疼痛无差异。
