The aim of this study was to investigate the effect of photobiomodulation therapy (PBMT) as pre-treatment on pain level during injection in the anterior maxillary region. 56 Patients were randomly divided into 3 groups, Group 1:980 nm diode laser (n = 22) (experimental), Group 2:980 nm diode laser probe placed in vestibule without radiation (placebo) (n = 22), Group3: no pre-treatment before injection (n = 12) (control). Pain level during injection was evaluated by visual analog scale (VAS). The severity of pain in Group 1(experimental) and Group 2 (placebo) was significantly lower than Group 3 (control). Group 1 had a lesser pain level than Group 2, but the difference in pain level between them was not significant. PBMT with 980 nm wavelength decreased pain level during local anesthesia injection without superiority over placebo.
本研究旨在探讨光生物调节疗法 (PBMT) 作为上颌前区注射前预处理对疼痛程度的影响。56 名患者被随机分为 3 组，第 1 组：980nm 二极管激光（n=22）（实验组），第 2 组：980nm 二极管激光探头置于前庭但不辐射（安慰剂）（n=22），第 3 组：注射前无预处理（n=12）（对照组）。通过视觉模拟评分（VAS）评估注射过程中的疼痛程度。第 1 组（实验组）和第 2 组（安慰剂）的疼痛程度明显低于第 3 组（对照组）。第 1 组的疼痛程度低于第 2 组，但两组之间的疼痛程度差异无统计学意义。980nm 波长的 PBMT 可降低局部麻醉注射过程中的疼痛程度，但与安慰剂相比并无优势。
