Data sources Medline, EMBASE, PubMed and Scopus databases were used as the data sources for the systematic review. Articles published between 1 January 1990 to 31 October 2018 were included with no language restrictions. A manual search of the references lists of the selected studies and review articles was conducted.Study selection Two independent researchers identified observational studies that investigated at least one risk factor of root caries in the study population. Studies were only included if they demonstrated statistical analysis of data on root caries, had a sample size of >100 and were in vivo. A third researcher was consulted to achieve consensus if there was disagreement. Methodological quality was evaluated via the modified Newcastle-Ottawa Scale for cross-sectional studies.Data extraction and synthesis Data was extracted and pooled into descriptive summary tables with study characteristics and results. Data on the presence and extent of root caries was recorded in addition to information on the relationship between the studied factors and root caries found in the unadjusted and adjusted data. Due to heterogeneity of key aspects among the included studies, meta-analysis was not conducted. Data were grouped under six categories - sociodemographic, general health behaviour, general health condition, fluoride exposure, oral health behaviour and oral health condition - and qualitatively analysed.Results Following screening of 984 articles, 62 were included in methodological quality assessment. Twenty-five were classified as moderate quality, 37 as low quality and 18 excluded. Of the 44 included articles which were qualitatively analysed, a higher association of dental caries was found in tobacco users and those with low socioeconomic status, gingival recession, poor oral hygiene and in older age groups.Conclusions Based on the present evidence, there are a number of factors associated with root caries. More high-quality observational analytical studies are needed in this field in future studies.
资料来源 系统评价使用了 Medline、EMBASE、PubMed 和 Scopus 数据库作为数据来源。纳入了 1990 年 1 月 1 日至 2018 年 10 月 31 日期间发表的文献，无语言限制。对所选研究和综述文章的参考文献进行了手工检索。
研究选择 两名独立研究人员确定了观察性研究，这些研究在研究人群中调查了至少一个根龋风险因素。只有当研究显示了对根龋数据的统计分析、样本量大于 100 且为体内研究时，才将其纳入。如果存在分歧，将咨询第三名研究人员以达成共识。使用改良的 Newcastle-Ottawa 量表对横断面研究进行了方法学质量评估。
数据提取和综合 从描述性摘要表中提取和汇总数据，其中包括研究特征和结果。除了记录根龋的存在和程度外，还记录了研究因素与未调整和调整后数据中根龋之间关系的信息。由于纳入研究的关键方面存在异质性，因此未进行荟萃分析。数据分为六个类别 - 社会人口统计学、一般健康行为、一般健康状况、氟化物暴露、口腔健康行为和口腔健康状况 - 并进行了定性分析。
结果 在筛选了 984 篇文章后，有 62 篇文章纳入了方法学质量评估。25 篇被归类为中等质量，37 篇为低质量，18 篇被排除。在进行定性分析的 44 篇纳入文章中，发现吸烟和社会经济地位较低的人、牙龈退缩、口腔卫生不良和年龄较大的人患龋齿的相关性更高。
结论 根据目前的证据，有许多因素与根龋有关。未来的研究需要在这一领域进行更多高质量的观察性分析研究。
