Effect of gingival stimulation (GS) with a toothbrush on periodontal disease was investigated in 16 periodontal patients during SPT phase. GS was applied to attached gingiva with probing depth (PD) of 4-6mm. The patients were trained for GS with a standardized manner and were asked to use the GS technique at experimental sites (ES, 30 sites) following their routine tooth brushing for about 1 month. In the contra lateral side, they were asked to use only their routine method for use as control sites (CS, 19 sites). Clinical assessments and measurements of gingival microcirculatory function (GMF) were performed before and after the experimental period. The Gingival index score decreased in ES (2.0-1.4) and CS (2.1-1.7). The decrease was significant in ES (p=0.0013) and approached significant level in CS (p=0.0520). No significant change was found for the Plaque index score in ES and CS.PD decreased significantly in ES (4.3mm-3.9mm, p=0.0007) and CS (4.6mm-4.0mm, p=0.0002). Attachment level did not change significantly in both sites. Among parameters of GMF, significant changes occurred in gingival crevicular fluid flow (65.0-47.4, p=0.0020) and pocket temperature (35.6-35.9, p=0.0418) in ES only. These result indicated that GS could improve gingival microcirculatory function, and suggested that GS might contribute to recovery of periodontal symptom

对16例牙周病患者在SPT期进行了牙龈刺激（GS）治疗。GS应用于附着牙龈，探测深度（PD）为4 - 6mm。患者接受标准化的GS训练，并在常规刷牙约1个月后，要求在实验部位（ES，30个部位）使用GS技术。在对侧，要求他们仅使用常规方法作为对照部位（CS，19个部位）。在实验期前后进行临床评估和牙龈微循环功能（GMF）的测量。牙龈指数评分在ES（2.0 - 1.4）和CS（2.1 - 1.7）中降低。在ES中降低显著（p = 0.0013），在CS中接近显著水平（p = 0.0520）。ES和CS的斑块指数评分无显著变化。ES（4.3 mm-3.9 mm，p = 0.0007）和CS（4.6 mm-4.0 mm，p = 0.0002）的PD显著降低。两个部位的依恋水平均无显著变化。在GMF参数中，仅ES组的龈沟液流量（65.0 - 47.4，p = 0.0020）和囊袋温度（35.6 - 35.9，p = 0.0418）发生显著变化。提示GS能改善牙龈微循环功能，可能有助于牙周症状的恢复
