Effect of Gingival Stimulation with a Toothbrush on Periodontal Diesease.

对16例牙周病患者在SPT期用牙刷刺激牙周的效果进行了研究。附着牙用GS，探诊深度4~6 mm。患者接受标准化的GS训练，并在常规刷牙后1个月左右在实验点(ES，30个点)使用GS技术。在对侧，他们被要求只使用他们的常规方法作为对照部位(CS，19个部位)。在实验前后分别进行临床评估和牙周微循环功能(GMF)的测定。牙周炎(ES)组(2.0~1.4)和牙周炎(CS)组(2.1~1.7)牙龈指数评分下降。ES组下降显著(p=0.0013)，CS组下降接近显著水平(p=0.0520)。斑块指数在ES组和CS组无明显变化，而PD在ES组(4.3 mm~3.9 mm，p=0.0007)和CS组(4.6 mm~4.0 mm，p=0.0002)显著降低。依恋水平在两个网站上没有显著变化。在GMF参数中，仅ES组的龈沟液流量(65.0~47.4，p=0.0020)和袋温度(35.6~35.9，p=0.0418)发生显著变化。提示GS可改善牙周微循环功能，提示GS可能有助于牙周症状的恢复。

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
