可摘局部义齿基牙健康状况的研究

A clinical observation on abutment teeth status in the patients wearing removable partial denture

目的 对比患者不同的口腔卫生习惯、不同的义齿设计、不同的义齿材料等 ,以分析可摘局部义齿(removablepartialdentures,RPDs)对口腔微生态的影响。方法 在患者戴入RPDs 3年后 ,用龋病、牙周病常用指数及口腔卫生指数来检查基牙健康状况 ,用 χ2 检验分析它们之间的结果有无差异。结果 患者的口腔卫生习惯、义齿的不同设计均与基牙健康密切相关。而两种不同材料的义齿对基牙的损坏无显著性差异。结论 RPDs基牙的健康与多因素有关 ,而口腔卫生状况是决定RPDs口腔微生态的重要因素。

Objective To compare the effect of different factors(①oral hygiene habits,②designs of dentures,③material of dentures) on abutment teeth of removable partial dentures (RPDs).Methods The abutment teeth status were examined before and after they had worn RPDs for three years on items of caries,periodontal and oral hygiene habits.The results were analyzed with χ 2 statistics.Results The patient's oral hygiene habits and different designs of dentures had close relation with abutment teeth status,but different material of dentures had no effects.Conclusion The abutment teeth status are related many factors,but oral hygiene is a most important factor.
