Background: This study aimed to assess the dental caries and erosion status of 12-year-old Hong Kong children and study the determinants of dental caries and dental erosion of these children. Methods: The survey was performed from 2011 to 2012 with ethics approval. Stratified random sampling was adopted to select 12-year-old children in 7 primary schools in Hong Kong. The participating parents were asked to complete a self-administered questionnaire concerning their children's diet and oral health habits. The children were examined for caries status with WHO criteria by 3 calibrated examiners. Detection of dental erosion followed Basic Erosive Wear Examination (BEWE) criteria. Results: A total of 704 children were recruited and 600 (316 boys, 53%) participated in the survey. There were 124 children (21%) with caries experience (DMFT > 0) and their DMFT was 0.34 +/- 0.76. About half of their decay was unfilled (DT = 0.16 +/- 0.52) The DMFT of girls and boys were 0.45 +/- 0.89 and 0.23 +/- 0.61, respectively (p = 0.001). Girls also had a higher DT (0.21 +/- 0.62 compared with 0.11 +/- 0.41, p = 0.013) and FT than boys (0.23 +/- 0.63 compared with 0.12 +/- 0.44, p = 0.016). Most children (75%) had at least some sign of erosion (BEWE > 0), but no severe erosion (BEWE = 3). Logistic regression showed girls who consumed soft drinks and took vitamin C supplements had higher caries risk. Dental erosion was more severe among the children who had caries experience and consumed fruit juice. Conclusions: The 12-year-old Hong Kong children had low caries experience, and almost
