Pain is a multidimensional construct that involves sensory, emotional, and cognitive processes. It is an essential component of child behavior guidance. The injection of a local anesthetic agent during pediatric dental treatment is one of the most painful and distressing procedures performed, stimulation of acupoint LI4 provides an analgesic effect in the orofacial region, thus decreasing the pain during injection.
To compare and evaluate the effect of low-level laser on LI4 acupoint and surface-acting 20% benzocaine gel during local anesthesia.
Children of age-group between 5 years and 9 years receiving bilateral local anesthesia were scheduled for dental treatment. Split-mouth cross-over study was planned and was divided into two groups, receiving low-level laser acupuncture on LI4 acupoint with placebo as a moist cotton swab in the first visit and 20% benzocaine gel with placebo as low-level laser acupuncture off mode in second visit and vice versa. Pain intensity was evaluated using the sound eye motor scale as subjective scale, Wong-Bakers pain rating scale. Pulse rate was measured before, during, and after the procedure using a pulse oximeter.
The average heart rate, Wong-Bakers pain rating scale, and Sound Eye Motor scale were significantly lower in the group having low-level laser when compared with the group having placebo low-level laser therapy.
The low-level laser can be used to control pain during local anesthesia in children.

疼痛是一个多维度的概念，涉及感觉、情感和认知过程。它是儿童行为引导的重要组成部分。在儿童牙科治疗期间注射局部麻醉剂是最痛苦和令人苦恼的操作之一，刺激合谷穴（LI4）可在口面部区域产生镇痛效果，从而减轻注射时的疼痛。
比较和评估低强度激光对合谷穴（LI4）与表面作用的20%苯佐卡因凝胶在局部麻醉期间的效果。
计划对年龄在5至9岁之间接受双侧局部麻醉的儿童进行牙科治疗。采用分口交叉研究，分为两组，在第一次就诊时，一组在合谷穴（LI4）接受低强度激光针刺，用湿棉签作为安慰剂；在第二次就诊时，另一组接受20%苯佐卡因凝胶，用低强度激光针刺关闭模式作为安慰剂，反之亦然。使用声眼运动量表作为主观量表、面部表情疼痛评分量表评估疼痛强度。在操作前、操作期间和操作后使用脉搏血氧仪测量脉搏率。
与接受安慰剂低强度激光治疗的组相比，接受低强度激光治疗的组的平均心率、面部表情疼痛评分量表和声眼运动量表得分显著更低。
低强度激光可用于控制儿童局部麻醉期间的疼痛。
