Numerous studies have documented the clinical outcomes of laser therapy for untreated periodontitis, but very few have reported on lasers treating inflamed pockets during maintenance therapy. The aim of this study is to compare the effectiveness of scaling and root planing (SRP) plus the adjunctive use of diode laser therapy to SRP alone on changes in the clinical parameters of disease and on the gingival crevicular fluid (GCF) inflammatory mediator interleukin-1β (IL-1β) in patients receiving regular periodontal maintenance therapy.
This single-masked and randomized, controlled, prospective study includes 22 patients receiving regular periodontal maintenance therapy who had one or more periodontal sites with a probing depth (PD) ≥ 5 mm with bleeding on probing (BOP). Fifty-six sites were treated with SRP and adjunctive laser therapy (SRP + L). Fifty-eight sites were treated with SRP alone. Clinical parameters, including PD, clinical attachment level (CAL), and BOP, and GCF IL-1β levels were measured immediately before treatment (baseline) and 3 months after treatment.
Sites treated with SRP + L and SRP alone resulted in statistically significant reductions in PD and BOP and gains in CAL. These changes were not significantly different between the two therapies. Similarly, differences in GCF IL-1β levels between SRP + L and SRP alone were not statistically significant.
In periodontal maintenance patients, SRP + L did not enhance clinical outcomes compared to SRP alone in the treatment of inflamed sites with ≥ 5 mm PD.
众多研究记录了激光疗法治疗未经治疗的牙周炎的临床结果，但很少有关于激光疗法在维持治疗期间治疗炎症牙周袋的报道。本研究的目的是比较在接受常规牙周维持治疗的患者中，龈下刮治术和根面平整术（SRP）联合二极管激光辅助治疗与单纯SRP治疗对疾病临床参数变化以及龈沟液（GCF）中炎症介质白细胞介素-1β（IL-1β）的影响。
这项单盲、随机、对照的前瞻性研究纳入了22例接受常规牙周维持治疗的患者，这些患者有一个或多个牙周位点探诊深度（PD）≥5mm且探诊出血（BOP）。56个位点接受了SRP联合激光辅助治疗（SRP+L）。58个位点仅接受了SRP治疗。在治疗前（基线）和治疗后3个月测量临床参数，包括PD、临床附着水平（CAL）和BOP，以及GCF中IL-1β水平。
接受SRP+L和单纯SRP治疗的位点在PD和BOP方面均有统计学意义的降低，CAL有所增加。两种治疗方法之间的这些变化没有显著差异。同样，SRP+L和单纯SRP治疗在GCF中IL-1β水平上的差异也没有统计学意义。
在牙周维持治疗患者中，对于PD≥5mm的炎症位点，与单纯SRP相比，SRP+L并没有改善临床疗效。
