The aim of this study, conducted in 1994, was to examine the association between approximal caries and sugar consumption in teenagers residing in three fluoride-deficient areas in Iceland while controlling for a number of behavioral, residential and microbiological factors. One hundred and fifty subjects (mean age 14 years) selected from the Icelandic Nutritional Survey (INS) were examined radiographically and they completed questionnaires about sugar consumption frequency. Total grams of sugar intake were obtained from the INS for each subject. Caries experience on approximal surfaces, diagnosed from radiographs, was used as the dependent variable in the analyses. Altogether 45.2% of subjects were caries free on approximal surfaces. The overall sample was found to have a mean DFS on approximal surfaces of 2.73 (s=4.36) per subject. Average daily total sugar intake was 170 g per subject and the mean number of sugar-eating occasions between meals was 5.32 (s=6.29) per subject. The regression model indicated that the frequency of between-meal sugar consumption was associated with approximal caries, with frequency of candy consumption being the most important of the sugar variables. In multivariate analysis, no relationship was found between dental caries and total daily intake of sugar, although a significant relationship between total sugar consumption and presence of caries was seen in bivariate analysis. Between-meal consumption of sugar remains a risk factor for the occurrence of dental caries, especially in populations with moderate-to-high levels of dental caries experience.
这项于1994年开展的研究旨在调查冰岛三个缺氟地区青少年邻面龋与糖消耗之间的关联，同时控制一系列行为、居住和微生物学因素。从冰岛营养调查（INS）中选取了150名受试者（平均年龄14岁）进行了影像学检查，并完成了关于糖消耗频率的问卷调查。从INS获取了每位受试者的糖摄入总量。分析中使用从X光片诊断出的邻面龋经验作为因变量。共有45.2%的受试者邻面无龋。总体样本的邻面平均DFS为每人2.73（标准差=4.36）。每位受试者的每日平均糖摄入总量为170克，每餐之间吃糖次数的平均值为每人5.32（标准差=6.29）。回归模型表明，餐间吃糖频率与邻面龋有关，其中糖果消耗频率是糖变量中最重要的因素。在多变量分析中，未发现龋齿与每日糖总摄入量之间存在关联，尽管在双变量分析中观察到总糖消耗与龋齿存在之间存在显著关联。餐间吃糖仍然是龋齿发生的一个危险因素，尤其是在龋齿发生率处于中高水平的人群中。
