BACKGROUND
There is insufficient clinical and microbiological evidence to support the use of diode laser and air-polishing with erythritol as supplements to scaling and root planning(SRP). The aim of the current study is to evaluate the clinical and microbiologic efficacy of erythritol subgingival air polishing and diode laser in treatment of periodontitis.
METHODS
The study encompassed twenty-four individuals seeking periodontal therapy and diagnosed with stage I and stage II periodontitis. Eight patients simply underwent SRP. Eight more patients had SRP followed by erythritol subgingival air polishing, and eight patients had SRP followed by diode laser application. At baseline and six weeks, clinical periodontal parameters were measured, including Plaque Index (PI), Gingival Index (GI), periodontal Probing Depth (PPD), and Clinical Attachment Level (CAL). The bacterial count of Aggregatibacter actinomycetemcomitans(A.A), Porphyromonas gingivalis (P.G) was evaluated at different points of time.
RESULTS
The microbiological assessment revealed significant differences in the count of A.A. between the laser and erythritol groups immediately after treatment, indicating a potential impact on microbial levels. However, the microbial levels showed fluctuations over the subsequent weeks, without statistically significant differences. Plaque indices significantly decreased post-treatment in all groups, with no significant inter-group differences. Gingival indices decreased, and the laser group showed lower values than erythritol and control groups. PPD and CAL decreased significantly across all groups, with the laser group exhibiting the lowest values.
CONCLUSION
The supplementary use of diode laser and erythritol air polishing, alongside SRP, represents an expedited periodontal treatment modality. This approach leads to a reduction in bacteria and improvement in periodontal health.

背景
目前尚无充分的临床和微生物学证据支持二极管激光和使用赤藓糖醇的空气抛光作为牙周刮治和根面平整（SRP）的补充治疗。本研究旨在评估赤藓糖醇龈下空气抛光和二极管激光治疗牙周炎的临床和微生物疗效。
方法
本研究纳入了 24 名寻求牙周治疗且诊断为 I 期和 II 期牙周炎的个体。8 名患者仅接受 SRP 治疗。8 名患者在 SRP 后接受赤藓糖醇龈下空气抛光治疗，8 名患者在 SRP 后接受二极管激光治疗。在基线和 6 周时，测量了牙周临床参数，包括菌斑指数（PI）、牙龈指数（GI）、牙周探诊深度（PPD）和临床附着水平（CAL）。在不同时间点评估了伴放线放线杆菌（A.A）和牙龈卟啉单胞菌（P.G）的细菌计数。
结果
微生物评估显示，激光组和赤藓糖醇组在治疗后即刻 A.A 的计数存在显著差异，表明对微生物水平有潜在影响。然而，微生物水平在随后的几周内波动，无统计学差异。所有组在治疗后菌斑指数均显著下降，组间无显著差异。牙龈指数下降，激光组的值低于赤藓糖醇组和对照组。所有组的 PPD 和 CAL 均显著下降，激光组的值最低。
结论
在 SRP 基础上联合使用二极管激光和赤藓糖醇空气抛光作为牙周辅助治疗方法，是一种加速牙周治疗的手段。这种方法可以减少细菌数量，改善牙周健康。
