It was examined, in this study, whether the tannin-fluoride preparation (HY preparation), which might have a caries reductive, plaque inhibiting and astringent action, could reduce the incidence of gingival inflammation around abutment teeth for removable partial dentures. Zinc oxide eugenol cement mixed with HY preparation filled in the cavity prepared in the resin base facing the abutment tooth. Crevicular fluid (Periotron unit: GCF), gingival index (GI), plaque index (PII), probing depth and caries activity around the abutment tooth were measured during 12 months. The following results were obtained: 1. GCF decreased at 1 month later and showed low values at 2, 3, 6 and 12 months. 2. The percentage of low GI value showed an increasing tendency during the experimental period. 3. There was slight variation in PII and probing depth during the experimental period. 4. Caries activity showed a decreasing tendency. These results indicate that the tannin-fluoride preparation reduces not only caries activity but also gingival inflammation around abutment tooth.
本研究旨在探讨可能具有防龋、抑制菌斑和收敛作用的单宁氟制剂（HY制剂）是否能降低可摘局部义齿基牙周围牙龈炎症的发生率。将氧化锌丁香酚水门汀与HY制剂混合，填充于树脂基托面向基牙制备的窝洞内。在12个月内测量基牙周围的龈沟液（Periotron装置：GCF）、牙龈指数（GI）、菌斑指数（PII）、探诊深度和龋活性。获得以下结果：1. 1个月后GCF降低，在2、3、6和12个月时呈低值。2. 在实验期间，低GI值的百分比呈上升趋势。3. 实验期间PII和探诊深度有轻微变化。4. 龋活性呈下降趋势。这些结果表明，单宁氟制剂不仅能降低龋活性，还能减轻基牙周围的牙龈炎症。
