Keywords:dental caries, DMFT, oral hygiene, fluoride supplement, perception of oral health
A cross-sectional analytical study involved 365 first and second year students in Thaibinh Medical University, Vietnam. The purpose of the study was to ascertain prevalence of dental caries (as measured by score for decayed, filled, and missing teeth [DMFT]), and risk factors for caries, in study subjects. The prevalence of caries (DMFT > 0) was 70.4 and the mean DMFT was 2.28 ± 2.18. The mean filled teeth score was low (only 0.05 ± 0.46). Only a limited percentage of subjects (56.7%) had ever visited a dentist, and an even smaller proportion had visited for a dental checkup (13.5%). Just above 50% of participants had ever used at least one type of fluoride supplement (not including fluoridated toothpaste). A significant positive association was observed between mother’s education and use of fluoride supplements. Brushing after getting up and having regular brushing schedule were protective factors against dental caries. Perceptions of tooth damage and school absence due to oral health were significantly associated with increased dental caries.
