A random sample of 1019 elderly home dwelling persons participated in this study. There were 809 dentate respondents, 28.6% of whom wore removable partial dentures. They were examined for coronal and root caries, gingival recession, pocket depth and loss of gingival attachment. The removable partial dentures were also evaluated. Abutment teeth were found to be more likely to have caries and periodontal disease than all other teeth. Using a MANOVA statistical procedure, the analysis indicated that the partial denture itself, irrespective of any professionally determined problems with the denture, appears to affect coronal and root caries on the teeth of partial denture wearers. Partial dentures judged to need repair or adjustment were related to periodontal status. The data on adverse effects of partial dentures suggest a need for patient education by the dentist and through public health measures, and good oral self care and regular professional recall for people who wear removable partial dentures.
1019名居家老年人的随机样本参与了本研究。有809名有牙颌受访者，其中28.6%佩戴可摘局部义齿。对他们进行了冠龋和根龋、牙龈退缩、牙周袋深度及牙龈附着丧失情况的检查。同时对可摘局部义齿进行了评估。发现基牙比所有其他牙齿更易患龋病和牙周疾病。采用多变量方差分析统计方法，分析表明局部义齿本身，无论义齿存在任何专业判定的问题，似乎都会影响局部义齿佩戴者牙齿的冠龋和根龋。被判定需要修复或调整的局部义齿与牙周状况有关。局部义齿不良反应的数据表明，牙医需要通过患者教育和公共卫生措施，以及让佩戴可摘局部义齿的人做好口腔自我护理并定期进行专业复诊。
