This study investigated the association between denture status [implant-supported fixed dentures (IDs) and removable partial dentures (RPDs)] and oral health-related quality of life (OHRQoL).
Consecutive patients with IDs and RPDs were recruited from the Prosthodontics Departments at Showa University and Tokyo Medical and Dental University. The Japanese version of the Oral Health Impact Profile (OHIP-J-49) was administered to each subject. For each OHIP-J-49 question, the subjects were asked to indicate the frequency with which they had experienced a dental problem during the last month. Responses were recorded on a 5 point Likert rating scale, with 0 being never and 4, very often. Summary scores were calculated and regression analyses conducted to investigate the association between denture status and OHIP-J-49 summary score.
In total 79 ID subjects (mean age±SD of 51.7±12.4 years, 44.3% men) and 109 RPD subjects (mean age of 66.5±8.6 years, 30% men) participated after giving informed consent. The regression analysis between the type of treatment and the OHIP-J-49 summary score revealed a significant association with a coefficient of 17.0 (Confidence interval, CI: 10.9-23.1). When age and duration of denture usage, which had significant associations with OHIP-J-49, were included in this model, the regression coefficient remained virtually unchanged at 17.4 (CI: 9.75-25.0), thus indicating little potential confounding by them.
OHRQoL in patients with implant-supported fixed dentures is generally less impaired than it is in those patients with RPDs.
本研究调查了义齿状况[种植体支持的固定义齿（IDs）和可摘局部义齿（RPDs）]与口腔健康相关生活质量（OHRQoL）之间的关系。
连续从昭和大学和东京医科齿科大学的修复科招募了 ID 和 RPD 患者。每位受试者均接受了日本版口腔健康影响量表（OHIP-J-49）的评估。对于每个 OHIP-J-49 问题，要求受试者指出在过去一个月中经历过的牙齿问题的频率。答案记录在 5 分 Likert 评分量表上，0 表示从未有过，4 表示经常有。计算综合评分并进行回归分析，以调查义齿状况与 OHIP-J-49 综合评分之间的关系。
共有 79 名 ID 受试者（平均年龄±标准差为 51.7±12.4 岁，44.3%为男性）和 109 名 RPD 受试者（平均年龄为 66.5±8.6 岁，30%为男性）在知情同意后参与了研究。治疗类型与 OHIP-J-49 综合评分之间的回归分析显示，两者之间存在显著关联，回归系数为 17.0（置信区间，CI：10.9-23.1）。当年龄和义齿使用时间这两个与 OHIP-J-49 有显著关联的因素纳入该模型时，回归系数几乎不变，仍为 17.4（CI：9.75-25.0），这表明它们的潜在混杂作用很小。
与 RPD 患者相比，种植体支持的固定义齿患者的 OHRQoL 通常受损程度较轻。
