AbstractBackground: Dental erosion is a neglected problem. Adolescents is supposedly a vulnerable group to dental erosion. This study, targeting adolescents in Hong Kong, aimed to characterize their dental erosion status, evaluate their awareness, compare the effectiveness of professionalled and peer-led health education, and provide basic dental services. Methods: Two schools with similar sociodemographic and academic background were selected and randomly assigned into control and experimental groups, for receiving professional-led and peer-led education, respectively, on dental erosion prevention. Secondaryfour students were recruited and completed questionnaires on knowledge of dental erosion and related behaviors at baseline and two weeks post-intervention. Participants’ erosion status was assessed using the Basic Erosive Wear Examination (BEWE) index. Dental check-ups, oral hygiene instructions, dietary advice and fluoride application were provided. Results: A total of 206 (90 males and 116 females) adolescents participated and completed both baseline and follow-up questionnaires. Their mean age was 15.5 years (SD=0.66). Only approximately one-quarter (26.7%) of the participants had heard about dental erosion. The common behaviours related to erosion were frequent intake of citrus fruits (69.9%) and soft drinks (34.0%). Both control and experimental groups presented with significant knowledge gain (p<0.001) after intervention. The total knowledge score increased by 298% and 171% for control and experimental groups respectively, with significantly greater knowledge gain in the control group (p=0.005). Both groups did not generate significant changes in related behaviors (immediate brushing after eating, induced vomiting, and frequent intakes of acidic drinks and foods) (all p>0.05). There was no significant difference in the behavioural change between the two groups (p=0.133). A total of 157 participants received the oral examination and dental services. Among them, 56 (35.7%) exhibited any signs of erosion (BEWE>0). Under the BEWE criteria, 134 (85.4%) were defined as “no risk of erosion” (i.e. BEWE=0-2). Conclusions: Dental erosion is common among adolescents in Hong Kong. Their awareness of dental erosion is extremely low. Both peer-led and professional-led education are effective in improving knowledge on dental erosion, whereas professional-led approach generates greater knowledge gain. Behavioural changes, however, are limited in both groups. Concerted efforts from all stakeholders (health authority, public health workers, healthcare providers, schools, parents and students) are needed for the control of dental erosion.
