Abstract：
OBJECTIVE: The aim of this study was to evaluate the clinical outcomes of diode laser as an adjunct to nonsurgical periodontal therapy (NSPT) for residual periodontal pockets in mandibular second molars.
METHODS: Sixty-seven mandibular second molars (154 residual periodontal pockets) were recruited into the study and randomly assigned to the Laser + NSPT group and the NSPT group. The Laser + NSPT group underwent NSPT adjunct with diode laser radiation (wavelength: 810 nm, power: 1.5 W, 40 s maximum), while the NSPT group underwent nonsurgical periodontal therapy alone. Clinical parameters were measured at baseline (T0) and 4(T1), 12(T2), and 24(T3), weeks after treatment.
RESULTS: Periodontal pocket depth (PPD), clinical attachment loss (CAL), and bleeding on probing (BOP) in both groups showed significant improvements at the end of study compared to baseline. The reductions of PPD, CAL, and BOP in the Laser + NSPT group were significantly greater than NSPT group. At T3, the Laser + NSPT group had a mean PPD of 3.06 ± 0.86 mm, CAL of 2.58 ± 0.94 mm and BOP of 15.49%, while the NSPT group had a mean PPD of 4.46 ± 1.57 mm, CAL of 3.03 ± 1.25 mm and BOP of 64.29%.
CONCLUSIONS: The diode laser as an adjunct to nonsurgical periodontal therapy may contribute to clinical outcomes for residual periodontal pockets. However, the approach may cause reduction of keratinized tissue width.
BACKGROUND: This study was registered in the Chinese Clinical Trial Registry ChiCTR2200061194.

摘要：
目的：本研究的目的是评估二极管激光作为非手术牙周治疗（NSPT）辅助治疗下颌第二磨牙残留牙周袋的临床效果。
方法：将67个下颌第二磨牙（154个残留牙周袋）纳入研究，随机分为激光NSPT组和NSPT组。激光+NSPT组接受NSPT辅助二极管激光辐射(波长:810nm,功率:1.5W,最大40s)，而NSPT组仅接受非手术牙周治疗。在基线（T0）和4（T1）测量临床参数，12(T2),24（T3）治疗后几周。
结果：牙周袋深度（PPD），临床附着丧失(CAL)，与基线相比，两组的探查出血（BOP）在研究结束时显示出显着改善。PPD的减少，CAL,激光+NSPT组BOP明显大于NSPT组。在T3时，激光+NSPT组的平均PPD为3.06±0.86mm，CAL为2.58±0.94mm,防喷器为15.49%,而NSPT组的平均PPD为4.46±1.57mm，CAL为3.03±1.25mm,防喷器为64.29%。
结论：二极管激光作为非手术牙周治疗的辅助手段可能有助于牙周袋残留的临床结局。然而,该方法可能导致角化组织宽度减小。
背景：本研究已在中国临床试验注册中心ChiCTR2200061194注册。
