To determine the prevalence of dental erosion in a stratified sample of 5-year-old children and to investigate whether demographic and dietary factors were associated.
Cross sectional study in Cork City and County.
A sample of 202 5-year-old children stratified on fluoridation status was selected. Measurement of erosion used a scoring system and criteria based on those used in the UK. Wear on the palatal and labial surfaces of primary maxillary teeth considered to be predominantly erosive was assessed. Demographic and dietary details were collected via a parental questionnaire. Statistical analysis was stepwise logistic regression.
In lifetime residents of fluoridated areas (n = 114) 47% had evidence of erosion; in 21% erosion had progressed to the dentine or pulp. The corresponding figures in non-fluoridated areas (n = 76) were 43% and 21% respectively. The variables significantly associated with erosion to dentine or pulp were low socio-economic status, measured by low family income and the frequency of fruit squash and carbonated drink consumption.
The prevalence of dental erosion overall was 47%, in 21% erosion affected the dentine or pulp. Levels in fluoridated and non-fluoridated areas were similar. Low socio-economic status and frequency of fruit squash and carbonated drink consumption were associated with erosion extending to dentine or pulp.
确定5岁儿童分层样本中牙齿侵蚀的患病率，并调查人口统计学和饮食因素是否与之相关。
在科克市和郡进行的横断面研究。
选取202名按氟化状态分层的5岁儿童样本。采用基于英国使用的评分系统和标准对侵蚀情况进行测量。评估上颌乳前牙腭面和唇面主要被认为是侵蚀性的磨损情况。通过家长问卷收集人口统计学和饮食细节。统计分析采用逐步逻辑回归。
在氟化地区的常住居民（n = 114）中，47%有侵蚀迹象；21%的侵蚀已发展到牙本质或牙髓。在非氟化地区（n = 76），相应数字分别为43%和21%。与侵蚀发展到牙本质或牙髓显著相关的变量是社会经济地位低，以家庭收入低以及果汁饮料和碳酸饮料的消费频率来衡量。
牙齿侵蚀的总体患病率为47%，21%的侵蚀影响到牙本质或牙髓。氟化地区和非氟化地区的水平相似。社会经济地位低以及果汁饮料和碳酸饮料的消费频率与侵蚀扩展到牙本质或牙髓有关。
