背景:没有足够的临床和微生物学证据支持使用二极管激光和赤藓糖醇的空气抛光作为鳞片和根部规划(SRP)的补充。本研究的目的是评估赤藓糖醇牙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:该研究包括24名寻求牙周治疗并诊断为I期和II期牙周炎的个体。八名患者仅接受了SRP。另有8名患者接受了SRP,然后进行了赤藓糖醇龈下空气抛光,8例患者接受了SRP,然后应用了二极管激光。在基线和六周,测量牙周临床参数,包括斑块指数(PI),牙龈指数(GI),牙周探伤深度(PPD),和临床依恋水平(CAL)。放线菌的细菌计数(A.A),牙龈卟啉单胞菌(P.G)在不同的时间点进行评价。
结果:微生物学评估显示,治疗后立即激光组和赤藓糖醇组之间的A.A.计数存在显着差异,表明对微生物水平的潜在影响。然而,微生物水平在随后的几周内出现波动,没有统计学上的显著差异。各组治疗后斑块指数显著下降,组间无显著差异。牙龈指数下降,激光组显示低于赤藓糖醇和对照组。PPD和CAL在所有组显著下降,激光组表现出最低值。
结论:补充使用二极管激光和赤藓糖醇空气抛光,与SRP一起,代表加速牙周治疗方式。这种方法导致细菌的减少和牙周健康的改善。

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.
CONCLUSIONS: 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.
