To compare the frequency of denture stomatitis (DS) under maxillary complete dentures (CDs) in patients with opposing mandibular distal extension removable partial dentures (RPDs) and CDs.
Participants included 365 maxillary CD wearers (241 women, mean age 70.5 ± 13.2 years; 124 men, mean age 71.5 ± 10.4 years) from 7 rest homes in Istanbul. A total of 268 had mandibular CDs; 97 had mandibular distal extension RPDs. Two independent, calibrated examiners performed oral examinations. Presence of maxillary denture-related stomatitis and the effect of risk factors on DS were evaluated and recorded.
The frequency of palatal DS (Newton I-III) was 45.1% (n = 121) in the mandibular CD group and 49.5% (n = 48) in the mandibular distal extension RPD group, a statistically insignificant difference (p= 0.4). Factors significantly associated with palatal DS were maxillary denture age (p= 0.02), reduced occlusal vertical dimension (p= 0.04), and nocturnal denture wear (p= 0.03).
In this study, DS beneath maxillary CDs did not differ between mandibular distal extension RPD and CD wearers. The presence of mandibular anterior teeth did not influence the occurrence of palatal DS.
比较上颌全口义齿（CD）和下颌远中游离端可摘局部义齿（RPD）患者中义齿性口炎（DS）的发生率。
参与者包括来自伊斯坦布尔 7 家养老院的 365 名上颌 CD 佩戴者（241 名女性，平均年龄 70.5 ± 13.2 岁；124 名男性，平均年龄 71.5 ± 10.4 岁）。共有 268 名患者佩戴下颌 CD，97 名患者佩戴下颌远中游离端 RPD。两名独立的、经过校准的检查者进行了口腔检查。评估并记录上颌义齿相关口炎的存在以及危险因素对 DS 的影响。
下颌 CD 组的腭部 DS（Newton I-III）发生率为 45.1%（n=121），下颌远中游离端 RPD 组为 49.5%（n=48），差异无统计学意义（p=0.4）。与腭部 DS 显著相关的因素包括上颌义齿使用年限（p=0.02）、垂直距离减小（p=0.04）和夜间戴义齿（p=0.03）。
在本研究中，下颌远中游离端 RPD 和 CD 佩戴者的上颌 CD 下 DS 发生率无差异。下颌前牙的存在并不影响腭部 DS 的发生。
