The effect of smoking on nonsurgical periodontal treatment (SRP) is known, but the adjunct use of photobiomodulation (PBMT) to SRP has not been fully investigated in smokers. This study aimed to assess the effect of 820 nm diode laser on SRP in smoker/nonsmoker. Sixty patients (smokers/n = 30, nonsmokers/n = 30) were enrolled in this parallel-arm clinical study. All patients were divided into two main groups: SRP and PBMT + SRP. In PMBT + SRP groups, 7.96 J cm⁻² energy was applied by 820nm diode laser at baseline and first, second and third weeks after SRP. Periodontal pocket depth (PPD), gingival index (GI), plaque index (PI) and clinical attachment level (CAL) were recorded, and also gingival crevicular fluid (GCF) samples were collected at baseline and 6w after SRP. Total antioxidant capacity (TAOC) and total oxidative status (TOS) in GCF were analyzed. PBMT + SRP groups showed a statistically significant decrease in PPD and CAL, not in GI and PI compared with SRP alone. There were no statistically significant differences between smokers and nonsmokers in clinical data at six weeks after treatment. Although TAOC levels were increased in PMBT groups, TOS levels were decreased in all groups at the comparison of baseline and 6w after SRP. Adjunct use of 820 nm diode laser on SRP may improve the clinical parameters in smoker or nonsmoker patient with periodontitis.

820 nm 二极管激光对吸烟者和非吸烟者进行非手术牙周治疗的光生物调制疗法：一项单盲平行随机临床试验

吸烟对非手术牙周治疗 (SRP) 的影响是已知的，但尚未在吸烟者中对 SRP 辅助使用光生物调节 (PBMT) 进行充分研究。本研究旨在评估 820 nm 二极管激光对吸烟者/非吸烟者 SRP 的影响。60 名患者（吸烟者/ n = 30，非吸烟者/ n = 30）参加了这项平行组临床研究。所有患者分为两个主要组：SRP 和 PBMT + SRP。在 PMBT + SRP 组中，7.96 J cm ^-2在基线和 SRP 后的第一、第二和第三周通过 820nm 二极管激光器施加能量。记录牙周袋深度（PPD）、牙龈指数（GI）、菌斑指数（PI）和临床附着水平（CAL），并在基线和SRP后6周收集龈沟液（GCF）样本。分析了 GCF 中的总抗氧化能力 (TAOC) 和总氧化状态 (TOS)。与单独的 SRP 相比，PBMT + SRP 组的 PPD 和 CAL 有统计学意义的下降，而不是 GI 和 PI。治疗六周后，吸烟者和非吸烟者的临床数据无统计学差异。尽管 PMBT 组的 TAOC 水平升高，但在基线和 SRP 后 6 周的比较中，所有组的 TOS 水平都降低了。
