AbstractOBJECTIVES: This study aimed to compare the effectiveness of three topical fluoride application protocols in arresting dentin caries in primary teeth of preschool children. METHODS: Children aged 3-4 years who had at least one dentin caries lesion were recruited from 16 kindergartens in Hong Kong and were randomly allocated into three different intervention groups: Group 1 - annual application of 30% silver diammine fluoride (SDF) solution; Group 2 - three applications of 30% SDF solution at weekly interval; and Group 3 - three applications of 5% sodium fluoride (NaF) varnish at weekly interval. Information about the children‘s demographic and socio-economic background, and oral health related behaviors was collected by a questionnaire completed by their parents. The 18-month follow-up examinations were carried out by a masked examiner to assess whether the treated caries lesions had become arrested. RESULTS: A total of 304 children with 1670 tooth surfaces with dentin caries received treatment at baseline. After 18 months, 275 children (91%) were examined. The caries arrest rates at tooth surface level were 40%, 35% and 27% for Groups 1, 2 and 3, respectively (p<0.001). Using a Bayesian approach in analyzing clustered interval-censored data, both of SDF groups shortened the arrest time of dentin caries compared with the intensive NaF Group. Tooth type, tooth surface and presence of plaque at lesion had significant effects on caries arrest rates. CONCLUSIONS: Annual or intensive application of SDF solution is more effective in arresting dentin caries in primary teeth than intensive application of NaF varnish.
