To investigate any association between dental erosion and its potential dietary risk factors in a group of schoolchildren in Benghazi, Libya.
A cross-sectional observational study.
A random sample of 12-year-old schoolchildren in 36 randomly selected schools completed a questionnaire to provide dietary data and underwent dental examination. Dental erosion was assessed using UK National Diet and Nutrition Survey (2000) criteria. Associations between erosion and dietary variables under study were investigated through processes of bivariate and multivariate analyses.
Of 791 schoolchildren dentally examined, 40.8% had dental erosion; erosion into enamel affecting 32.5%, into dentine affecting 8% and into pulp affecting 0.3% of subjects. Bivariate analysis showed frequency of fruit-based sugary drink intake was statistically significantly and positively associated with erosion (p=0.006, Odds Ratio; 1.498, 95% CI; 1.124, 1.996) as was the length of time taken to consume acidic drinks (p≠0.005, Odds Ratio; 1.593, 95%CI; 1.161, 2.186). Additionally, multivariate analysis showed frequency of consumption of fruit other than bananas, sugared tea with milk and flavoured milk to also be positively associated with erosion (p=<0.05).
In this group of Libyan 12-year-olds, frequency of consumption of fruit-based sugary drinks and length of time taken to consume acidic drinks were the primary statistically significant positive risk factors for dental erosion.
调查利比亚班加西一群学童中牙齿侵蚀与其潜在饮食风险因素之间的任何关联。
一项横断面观察性研究。
从36所随机选择的学校中随机抽取12岁学童样本，完成一份问卷以提供饮食数据，并接受牙科检查。使用英国国家饮食与营养调查（2000年）标准评估牙齿侵蚀情况。通过双变量和多变量分析过程研究侵蚀与所研究饮食变量之间的关联。
在接受牙科检查的791名学童中，40.8%有牙齿侵蚀；侵蚀到牙釉质的占32.5%，侵蚀到牙本质的占8%，侵蚀到牙髓的占0.3%。双变量分析显示，以水果为基础的含糖饮料摄入频率与侵蚀在统计学上显著正相关（p = 0.006，优势比；1.498，95%置信区间；1.124，1.996），饮用酸性饮料的时间长度也是如此（p≠0.005，优势比；1.593，95%置信区间；1.161，2.186）。此外，多变量分析显示，除香蕉外的水果、加牛奶的甜茶和调味牛奶的消费频率也与侵蚀呈正相关（p < 0.05）。
在这群利比亚12岁儿童中，以水果为基础的含糖饮料消费频率和饮用酸性饮料的时间长度是牙齿侵蚀的主要统计学上显著的正风险因素。
