The aim of this study was to investigate data on the prevalence of tooth wear in adults and assess possible correlations using a systematic review.
A search of the literature, using PubMed and the Cochrane Library, from January 1980 to July 2007 was made using keywords "tooth + wear"; "dental + attrition + prevalence"; "dental + wear + prevalence"; "erosion + prevalence"; and "abrasion + prevalence". References were independently screened for inclusion and exclusion by two investigators and Cohen Kappa was used as the measure of agreement. Data were collected and converted into the Smith and Knight Tooth Wear Index.
One hundred eighty-six references were initially selected and subjected to the systematic review procedure; 13 survived the inclusion procedure. Four articles were suitable for regression analysis at tooth level (R2 = .593) and 3 at subject level (R2 = .736), using "age and age squared" and "age squared" as variables, respectively. Six studies reported males having significantly more tooth wear than females.
The predicted percentage of adults presenting with severe tooth wear increases from 3% at the age of 20 years to 17% at the age of 70 years. Increasing levels of tooth wear are significantly associated with age.
本研究旨在通过系统评价调查成年人牙齿磨损患病率的数据，并评估可能的相关性。
利用关键词“牙齿+磨损”“牙齿磨耗+患病率”“牙齿磨损+患病率”“侵蚀+患病率”和“磨损+患病率”，在1980年1月至2007年7月期间对PubMed和Cochrane图书馆的文献进行检索。由两名研究人员独立筛选参考文献以确定纳入和排除标准，并使用Cohen Kappa系数作为一致性的衡量指标。收集数据并转换为史密斯和奈特牙齿磨损指数。
最初选择了186篇参考文献并进行系统评价；13篇通过纳入程序。分别以“年龄和年龄平方”以及“年龄平方”为变量，4篇文章适用于牙齿水平的回归分析（R2 = 0.593），3篇适用于个体水平的回归分析（R2 = 0.736）。六项研究报告称男性牙齿磨损明显多于女性。
出现严重牙齿磨损的成年人预测百分比从20岁时的3%增加到70岁时的17%。牙齿磨损程度的增加与年龄显著相关。
