The aim of this study was to assess the prevalence of approximal enamel lesions from radiographs in groups of 14, 17, 20 and 23 years old, and to determine the relation with dentine lesions and restorations present.
Per age group, the bitewings of 120 persons were randomly selected and assessed for enamel lesions from the distal surface of the first premolar to the mesial surface of the second molar. A second examiner assessed 20% of the material for enamel lesions to determine the interexaminer agreement (Cohen's kappa = 0.63).
An enamel lesion was found in 12-15% of the unfilled surfaces. The mean number of surfaces with enamel lesions was almost three per person. For all age groups it was found that about 20% of the persons had at least four enamel lesions and the number of enamel lesions was significantly correlated with the number of dentine lesions. Of all enamel lesions 20% were found in persons without any dentinal lesions or restorations.
The bitewing radiographs showed a considerable number of enamel lesions for these age groups. This seems to justify its use on a routine base as a diagnostic tool at the age of 14-16 years.
本研究旨在评估14岁、17岁、20岁和23岁人群中通过X线片检查发现的邻面釉质病变的患病率，并确定其与现存牙本质病变及修复体的关系。
在每个年龄组中，随机选取120人的咬合翼片，评估从第一前磨牙远中面到第二磨牙近中面的釉质病变情况。另一位检查者对20%的材料进行釉质病变评估，以确定检查者间的一致性（科恩kappa值=0.63）。
在未充填的牙面上，12% - 15%发现有釉质病变。每人有釉质病变的牙面平均数近3个。在所有年龄组中，约20%的人至少有4处釉质病变，且釉质病变数量与牙本质病变数量显著相关。在所有釉质病变中，20%见于无任何牙本质病变或修复体的人。
对于这些年龄组，咬合翼片显示出相当数量的釉质病变。这似乎证明在14 - 16岁时将其作为常规诊断工具使用是合理的。
