The aims of the study were to determine the periodontal status of the teeth in contact with removable partial dentures (RPDs) and to compare them with other teeth in the opposing arch not related to any prosthesis. The periodontal status was also assessed in relation to the age of the dentures. Four hundred and twenty-seven patients treated with RPDs from 1981 to 1986 were recalled for examination. Prior to prosthetic treatment they were given periodontal treatment and fillings when required. Initially all were given oral hygiene instructions and motivation. They were reviewed regularly only on a short-term basis. Eighteen patients were suitable for the present study comprising of eight males and 10 females whose mean age was 41 years. The RPDs were in use from 1.5 to 8 years (mean 4.6 years). The following parameters were assessed: Plaque index (P1I), Gingival index (GI), loss of attachment (LA) and tooth mobility. The wearing of RPDs resulted in higher P1I, GI and LA compared to the controls and these differences were statistically significant. There was an increased frequency of higher P1I, GI and LA with the increase in denture age. Minor changes in tooth mobility were observed. It was concluded that the wearing of RPDs was detrimental to periodontal health in patients whose oral hygiene was less than adequate.
本研究的目的是确定与可摘局部义齿（RPD）接触的牙齿的牙周状况，并将其与对颌弓中与任何修复体无关的其他牙齿进行比较。还根据义齿的使用年限评估了牙周状况。对1981年至1986年接受RPD治疗的427名患者进行了回访检查。在进行修复治疗之前，根据需要对他们进行了牙周治疗和补牙。最初，所有患者都接受了口腔卫生指导和激励。他们只是在短期内定期接受复查。18名患者适合本研究，其中包括8名男性和10名女性，平均年龄为41岁。RPD的使用时间为1.5至8年（平均4.6年）。评估了以下参数：菌斑指数（P1I）、牙龈指数（GI）、附着丧失（LA）和牙齿松动度。与对照组相比，佩戴RPD导致P1I、GI和LA更高，这些差异具有统计学意义。随着义齿使用年限的增加，P1I、GI和LA较高的频率增加。观察到牙齿松动度有轻微变化。得出的结论是，对于口腔卫生状况欠佳的患者，佩戴RPD对牙周健康有害。
