RESUMO
Background: Resin infiltration is a technique in which a low-viscosity resin penetrates the proximal carious lesions and stops caries progression. Aim: This study aimed to compare the progression of proximal enamel caries of primary molars following the application of resin infiltrant clinically and radiographically vs Tooth Mousse. Materials and methods: This case-control split-mouth study evaluated 64 proximal surfaces of primary molars in 32 patients. Each patient had one pair of noncavitated proximal caries in two primary molars from different quadrants with radiographic evidence of enamel involvement. The carious lesions in each patient were randomly treated with resin infiltrant and Tooth Mousse. Progression of carious lesions was evaluated clinically and radiographically after 12 months. The two groups were compared by Fisher's exact test. Results: No caries progression was noted in the resin infiltrant group at 12 months, and all 32 surfaces (100%) showed cessation of caries. Four surfaces (12.5%) in the Tooth Mousse group showed caries progression. The two groups were not significantly different in this regard (p = 0.242). Conclusion: Resin infiltrant and Tooth Mousse were both effective in stopping the progression of proximal enamel caries of primary molars.
