Dental caries are attributed to various factors including diet. The present crosssectional study determined the frequency of sugary food and drink consumption and defined its relationship to dental caries among preschool children. A total of 50 preschoolers (aged 5-6 years) in three kindergartens of the Department of Community Development (KEMAS) in Titiwangsa, Kuala Lumpur participated in this study. A set of structured questionnaires was used to assess the frequency of sugary food and drink consumption. Dental check ups were performed by a dentist. The dft index (decayed, filled teeth) was used to describe incidence of caries in subjects. Results showed that 62% of the subjects had dental caries. with the mean dft score being 3.72. The frequency of sugary food consumption by the majority of subjects was 2 times a day, while the frequency of sugary drink consumption was more than 3 times a day. There was no significant relationship between frequency of sugary food and drink consumption with incidence of caries. Subjects with high dft scores were more likely to report dental pain. The prevalence of dental caries in preschoolers in this study was high, indicating a need for effective dental health promotion to improve dental health status of this age group.
