Abstract

BACKGROUND

The regular consumption of acidic foods and drinks may be associated with dental erosion, and soft drink consumption appears to be increasing both in developed and developing countries. Dentists are aware that an acidic diet can contribute to the development of erosion; however, there may be confusion within the profession concerning the general health message of eating five portions of fruits and vegetables each day.

OBJECTIVE

The aim of this study was to investigate associations between dental erosion and the consumption of acidic foods and beverages in schoolchildren in south-east Brazil. The objective was to gather information, by means of a dietary questionnaire, on frequency of intake and patterns of consumption of acidic foods and drinks in a group of schoolchildren. The hypothesis was that the experience of dental erosion among the study sample was associated with the frequency and pattern of consumption of soft drinks, fruit juices, fruits, and yogurt.

METHODS

A cross-sectional study was conducted in Três Corações, south-east Brazil. A sample of 458 schoolchildren, mean age 13.8 (SD 0.39) years, completed the study. Information about potential dietary risk factors for dental erosion was collected through a questionnaire survey completed by the schoolchildren. For the dental examinations, the subjects were examined for dental erosion in a school room. Associations between dental erosion and the variables under study were investigated through processes of bivariate and multivariate analyses. The statistical significance level was set at 5%.

RESULTS

Analysis of the questionnaire surveys showed that the frequency of consumption of sugared carbonated drinks was the only variable independently associated with the erosive process, with subjects who had a daily consumption of such drinks having a greater likelihood of having erosion (P = 0.015, odds ratio 1.752, 95% confidence interval 1.116-2.750).

CONCLUSIONS

Of all tested factors in this sample of schoolchildren the consumption of sugared carbonated drinks is most associated with dental erosion.

摘要

背景

经常食用酸性食物和饮料可能与牙齿侵蚀有关，而且在发达国家和发展中国家，软饮料的消费量似乎都在增加。牙医们意识到酸性饮食会导致牙齿侵蚀；然而，对于每天食用五份水果和蔬菜这一总体健康建议，业内可能存在困惑。

目的

本研究旨在调查巴西东南部学童牙齿侵蚀与酸性食物和饮料消费之间的关联。目的是通过饮食问卷收集一组学童酸性食物和饮料的摄入频率及消费模式信息。假设是研究样本中的牙齿侵蚀情况与软饮料、果汁、水果和酸奶的消费频率及模式有关。

方法

在巴西东南部的特雷斯科拉索斯进行了一项横断面研究。458名平均年龄为13.8岁（标准差0.39）的学童完成了该研究。通过学童填写的问卷调查收集有关牙齿侵蚀潜在饮食风险因素的信息。进行牙齿检查时，在教室对受试者进行牙齿侵蚀检查。通过双变量和多变量分析方法研究牙齿侵蚀与所研究变量之间的关联。统计学显著性水平设定为5%。
