Abstract

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 socioeconomic 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 socioeconomic factors, dental habits and oral hygiene. 1,204 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. This article is protected by copyright. All rights reserved.
