摘要
目的：观察基牙牙体牙周组织的健康状况，以了解可摘局部义齿（RemovablePartialDentures，RPDs）对口腔微生态平衡是否有影响，以及影响特点及相关因素。方法：在戴用RPDs后6个不同时期，分别测定314颗基牙的牙周指数、龋齿及患者口腔卫生状况。结果：①戴用RPDs6个月时，就有基牙发生龋坏，随着戴用时间延长，其患龋率逐渐升高（P＜0．001）；②戴用RPDs第2周时，就有基牙发生牙龈炎，且在前6个月内逐渐增加（P＜0．005），6个月之后又逐渐减少（P＜0.005）；③患者基础口腔卫生状况及卫生习惯，与基牙健康有着密切关系。结论：RPDs对口腔微生态系有较大影响，其影响程度主要取决于患者口腔卫生的好坏，其影响时期关键是戴用后前6个月。
Aims: The health condition of the bald tissue and periodontal tissue of abutments were observed to study if any effect of removable partial denturs (RPDs) to the oral microecosystem existed and for their features and other relative factors. Methods:The periodontal index, caries and oral hygiene of the 314 abutments were investigated ther wearing RPDs at sts different periods. Results: ①Caries occurred in some abutments after RPDs were worn for half a year, and the incidence of calles increased gradually(P < 0. 001); ②Gingivitis of the abutment teeth teeth ther wearing RPDs for only two weeks and this bend increased during the first six month(P < 0 .005)but decreased ther that;③The basic oral hygiene and health habits of the patients were closely related to the abutmental health. Conclusions: The RPDs apparently effect oral microecosystem. It mainly depends on the Oral hygiene status of the patients, especially during the first sts month ther wearing RPDs.
