This study aimed to assess the prevalence of erosive tooth wear among 3- to 5-year-old children in Hong Kong and to determine the effect of socio-economic factors, dental habits, and oral hygiene on their dental erosive wear status.
Stratified random sampling was adopted. Their parents were asked to complete a questionnaire regarding their children's backgrounds. A single examiner evaluated the children for erosive tooth wear using Basic Erosive Wear Examination (BEWE) criteria. Multiple logistic regression was used to determine the relationship between erosive wear and the children's socio-economic factors, dental habits, and oral hygiene.
1204 children participated in this study. Prevalence of erosive tooth wear (BEWE score > 0) was 14.9%. Among these, 153 children (12.8%) had initial wear, 21 children (1.8%) had distinct tooth loss, and five (0.4%) had severe erosive wear. Prevalence of erosive wear among the 3-, 4-, and 5-year-old children was 10.7%, 15.0%, and 17.7%, respectively. Increasing age, the low education of mother and high plaque scores were risk factors of erosive wear (P < 0.05).
Prevalence of erosive tooth wear is low among preschool children in Hong Kong. The erosive tooth wear prevalence increased with increasing age, lower education of mother, and poorer oral hygiene.
本研究旨在评估香港3至5岁儿童中侵蚀性牙齿磨损的患病率，并确定社会经济因素、牙齿习惯和口腔卫生对其牙齿侵蚀性磨损状况的影响。
采用分层随机抽样。要求他们的父母填写一份关于孩子背景的问卷。由一名检查者使用基本侵蚀性磨损检查（BEWE）标准对儿童的侵蚀性牙齿磨损进行评估。采用多元逻辑回归分析来确定侵蚀性磨损与儿童社会经济因素、牙齿习惯和口腔卫生之间的关系。
1204名儿童参与了本研究。侵蚀性牙齿磨损（BEWE评分>0）的患病率为14.9%。其中，153名儿童（12.8%）有初期磨损，21名儿童（1.8%）有明显的牙齿缺失，5名（0.4%）有严重的侵蚀性磨损。3岁、4岁和5岁儿童的侵蚀性磨损患病率分别为10.7%、15.0%和17.7%。年龄增长、母亲教育程度低和牙菌斑评分高是侵蚀性磨损的危险因素（P<0.05）。
香港学龄前儿童中侵蚀性牙齿磨损的患病率较低。侵蚀性牙齿磨损的患病率随着年龄的增长、母亲教育程度的降低和口腔卫生状况的变差而增加。
