Aim: The aim of this clinical study was to evaluate the effectiveness of four different topical fluoride agents in arresting primary active dentin caries lesions.
Methods: Children aged 3-5 years who had at least one active dentin caries lesion were included in this study for a period of 24 months. Teeth were randomly allocated into 4 groups: Group (1): 38% silver diamine fluoride (SDF), Group (2): 5% sodium fluoride (NaF), Group (3): amine fluoride (1250 ppm) and Group 4: 1,23% acidulated phosphate fluoride (APF). Children were evaluated every 6 months to assess whether the treated lesions had become arrested.
Results: A total of 124 children (male: 66, female: 58 ) with 1120 tooth surfaces with dentine caries received treatment at baseline. After 24 months, 122 children with 1115 dentin caries lesions remained in the study. The carries arrest rates at tooth surface level were 55%, 43%, 34% and 26% for Groups 1, 2, 3 and 4, respectively. This study showed that SDF application could arrest more dentine caries lesions compared with the NaF, AmF and APF application. Presence of plaque on lesion, tooth type, tooth surface and other variables including demographic background, oral health related behaviours, and baseline caries experience had no statistically significant effects on caries arrest rates.
Conclusion: SDF appliation is more effective in arresting dentine caries lesions in primary teeth than NaF, AmF and APF application.
