Tooth wear lesion, otherwise known as tooth surface loss, is an insidious cumulative and multifactorial condition causing irreversible destruction of tooth enamel and dentine. Over time this lesion can threaten the affected individual's Oral Health-Related Quality of Life (OHRQoL). OHRQoL entails interaction among oral health systems: social factors, psychological factors, and the rest of the body. Though, previous studies done decades ago also reported a high prevalence of tooth wear among the elderly in Nigeria, before now there has been no study on the impact of tooth wear types and severity on the OHRQoL of the elderly in this environment, which is necessary for their comprehensive management. The study was done to assess the impacts of tooth wear lesions on the Oral Health-Related Quality of Life of the elderly in Ibadan.
It was a cross-sectional study, involving 1,200 elderly individuals. Using a multistage random sampling technique, participants were randomly selected from 2 Local Government Areas in Ibadan. Data were obtained using a structured interviewer-administered questionnaire and oral examination using the Simplified Tooth Wear Index, as well as Geriatric Oral Health Assessment Index. Data were analysed using descriptive statistics at p ≤ 0.05.
Out of these elderly participants with Tooth wear lesions, 667 (55.6%) had good Oral Health-Related Quality of Life and 552 (43.5%) had poor Oral Health-Related Quality of Life. Attrition and Abfraction were the most common 1,189(99.1%) and least 5(0.4%) types of tooth wear lesions respectively. The lesions were more severe on the posterior teeth than the anterior teeth and more on the lower than the upper teeth.
The majority of the elderly with Tooth wear lesions had good OHRQoL, as more of them had mild to moderate grade of tooth wear.
牙齿磨损病变，也称为牙齿表面丧失，是一种隐匿性的累积性多因素病症，会导致牙釉质和牙本质的不可逆破坏。随着时间的推移，这种病变会威胁到受影响个体的口腔健康相关生活质量（OHRQoL）。OHRQoL涉及口腔健康系统之间的相互作用：社会因素、心理因素和身体的其他部分。尽管几十年前进行的先前研究也报告了尼日利亚老年人中牙齿磨损的高患病率，但在此之前，尚未有关于牙齿磨损类型和严重程度对该环境中老年人OHRQoL的影响的研究，而这对于他们的综合管理是必要的。该研究旨在评估牙齿磨损病变对伊巴丹老年人口腔健康相关生活质量的影响。
这是一项横断面研究，涉及1200名老年人。采用多阶段随机抽样技术，从伊巴丹的2个地方政府区域中随机选取参与者。使用结构化的访谈者管理问卷获取数据，并使用简化牙齿磨损指数以及老年口腔健康评估指数进行口腔检查。使用p≤0.05的描述性统计分析数据。
在这些患有牙齿磨损病变的老年参与者中，667人（55.6%）的口腔健康相关生活质量良好，552人（43.5%）的口腔健康相关生活质量较差。磨耗和楔状缺损分别是最常见的1189例（99.1%）和最少见的5例（0.4%）牙齿磨损病变类型。病变在后牙比前牙更严重，在下牙比上牙更多。
大多数患有牙齿磨损病变的老年人OHRQoL良好，因为他们中更多人患有轻度至中度的牙齿磨损。
