To evaluate the age-specific prevalence of erosive tooth wear in Japanese adults.
The study sample consisted of a total of 1108 adults aged 15-89 yrs in Tokyo, Japan. The subjects were asked to complete a self-administered nutrition-related questionnaire. Two examiners evaluated tooth wear in a full-mouth recording, using a modified tooth wear index developed based on the Smith and Knight Tooth Wear index. Subjects who had frequent acid consumption or gastric reflux and at least one tooth with an initial enamel wear were placed in an erosive wear positive group, and the rest of subjects were placed in the erosive wear negative group.
The median (IQR) prevalence of erosion was 19.1 (1.8) at enamel level and 6.5 (3.7) with dentin exposure. There were statistical differences in prevalence of erosive wear among different age groups (p<0.05). Dietary habits found to be frequent in erosive wear positive group included acidic juices for younger subjects (15-39 yrs), and acidic fruits for older subjects (60-89 yrs). The prevalence of gastroesophageal reflux and eating disorder was 3.5%. A severe loss of dental tissue was observed on labial and incisal surfaces of anterior teeth in the erosive wear positive group.
In the studied sample of Japanese adults, 26.1% had signs of erosive wear.
Erosive wear, in combination with abrasion and attrition, results in severe loss of tooth tissue. Frequent consumption of acidic fruits and drinks was significantly associated with erosive tooth wear at different age groups.
评估日本成年人中侵蚀性牙齿磨损的年龄特异性患病率。
研究样本包括日本东京的1108名年龄在15 - 89岁的成年人。受试者被要求完成一份与营养相关的自填式问卷。两名检查者使用基于史密斯和奈特牙齿磨损指数开发的改良牙齿磨损指数，在全口记录中评估牙齿磨损情况。将经常食用酸性食物或有胃食管反流且至少有一颗牙齿出现初始牙釉质磨损的受试者归入侵蚀性磨损阳性组，其余受试者归入侵蚀性磨损阴性组。
牙釉质水平的侵蚀患病率中位数（四分位间距）为19.1（1.8），牙本质暴露时为6.5（3.7）。不同年龄组的侵蚀性磨损患病率存在统计学差异（p<0.05）。在侵蚀性磨损阳性组中发现常见的饮食习惯包括年轻受试者（15 - 39岁）饮用酸性果汁，老年受试者（60 - 89岁）食用酸性水果。胃食管反流和饮食失调的患病率为3.5%。在侵蚀性磨损阳性组中，前牙的唇面和切缘表面观察到严重的牙体组织丧失。
在所研究的日本成年人样本中，26.1%有侵蚀性磨损迹象。
侵蚀性磨损与磨耗和磨损共同导致严重的牙体组织丧失。不同年龄组中频繁食用酸性水果和饮料与侵蚀性牙齿磨损显著相关。
