OBJECTIVE: The aim of the study was to analyze data collected from studies worldwide on the prevalence of edentulism and dental caries, in community-dwellers aged ≥ 45 years. DATA: Inclusion criteria; participants aged ≥ 45 years, community-dwellers. Exclusion criteria; participants aged < 45 years, in nursing homes, data obtained from dental clinics or pre-2005. The quality assessment tool by The National Heart, Lung and Blood Institute for Observational Cohort and Cross-sectional studies was used. Meta-analysis using the random-effects model (95% confidence interval) was done with data on participants who were edentulous and/or had active dental caries and stratified by regions of the world, age and Gross National Income per capita. Limitations in the data arose from several factors such as design of the studies included differences in socioeconomic status and access to health care among different countries. SOURCES: Embase, MEDLINE via Pubmed and Scopus, manual searches, from January 2016, restricted to English. Experts from different countries were contacted to identify National oral health surveys (NOHS) conducted from 2010 onwards. STUDY SELECTION: Eighty-six papers and seventeen NOHS were selected for data extraction. Majority of the studies (n = 69) were cross-sectional and of fair quality. 1.1%-70%, 4.9% - 98% prevalence of edentulism and dental caries, respectively. 22%, 45% estimated random-effects pooled prevalence of edentulism and dental caries, respectively. CONCLUSIONS: Within the limitations of this study, the findings indicate that untreated dental caries and tooth loss are prevalent on a global level with wide variations among different countries, age groups and socioeconomic status. CLINICAL SIGNIFICANCE: The findings demonstrate the reality of the new cohort of older adults, with higher tooth retention implying more dental caries incidence and the need for different care strategies to ensure better oral health. Large variations and difficulty in making comparisons among different countries highlight the need for more standardized, regular research.
目的：本研究旨在分析全球范围内针对≥45 岁社区居民的缺牙和龋齿患病率进行的研究数据。
数据：纳入标准；年龄≥45 岁的参与者，社区居民。排除标准；年龄<45 岁，疗养院，来自牙科诊所或 2005 年以前的数据。使用美国国立心肺血液研究所的观察性队列和横断面研究质量评估工具。对有缺牙和/或有活动性龋齿的参与者进行了荟萃分析，采用随机效应模型（95%置信区间），并按世界区域、年龄和人均国民总收入进行分层。数据存在局限性，这是由于包括研究设计在内的多种因素导致的，包括不同国家的社会经济地位和获得医疗保健的机会存在差异。
来源：Embase、通过 PubMed 和 Scopus 检索的 MEDLINE，从 2016 年 1 月开始，仅限于英文。联系了来自不同国家的专家，以确定从 2010 年开始进行的国家口腔健康调查（NOHS）。
研究选择：共选择了 86 篇论文和 17 项 NOHS 进行数据提取。大多数研究（n=69）为横断面研究，质量为中等。缺牙和龋齿的患病率分别为 1.1%-70%和 4.9%-98%。估计的缺牙和龋齿的随机效应汇总患病率分别为 22%和 45%。
结论：在本研究的局限性内，研究结果表明，未经治疗的龋齿和牙齿缺失在全球范围内普遍存在，不同国家、年龄组和社会经济地位之间存在广泛差异。
临床意义：研究结果表明，新的老年人群体的现实情况是，牙齿保留率较高意味着龋齿发病率更高，需要采取不同的护理策略来确保更好的口腔健康。不同国家之间的差异较大且难以进行比较，这突出表明需要进行更多标准化、定期的研究。
