Objectives: Test the hypothesis that 12% SDF is more effective than 5% fluoride varnish (FV) in arresting and preventing caries.

Methods: A randomized controlled trial comprising 227 six-year-old schoolchildren with untreated decay in the deciduous teeth. 120 individuals received 12% SDF (Cariestop®, Biodinâmica), and 107 received 5% FV (Duraflora®, Medicom). DMFT compared caries arrest and incidence at baseline, 6 and 12 months. Chi-square, Fisher exact test, McNemar, t-test, F test, ANOVA and Bonferroni were used.

Results: At baseline, DMFT indexes were 5.66 ± 3.62 for the SDF group and 5.42 ± 3.4 for the FV group (p = 0.628). SDF was significantly more effective than FV (p < 0.001), and the average numbers of arrested caries after 6 and 12 months were 2.17 ± 1.78 (preventive fraction= 46%; number needed to treat= 1) and 1.62 ± 1.48 (PF = 44%, NNT = 1), respectively. Neither group exhibited caries halt in the permanent dentition.

Conclusions: The results suggested that 12% SDF, applied annually, is more effective in arresting caries in deciduous teeth than 5% FV. No significant difference in the incidence of caries in permanent dentition was showed.
