The effect of resin infiltration on proximal caries lesions in primary and permanent teeth. A systematic review and meta-analysis of clinical trials

Overall, there was strong evidence that proximal caries lesion progression was less likely to occur in permanent teeth following treatment with resin infiltration plus oral hygiene measures as compared to non- invasive methods (oral hygiene instructions) for follow up 18 months to 2 years (3 studies: OR = 0.14; 95% CI: 0.08, 0.25; P < 0.001) as well as 3 years (4 studies: OR = 0.15; 95% CI: 0.06, 0.36; P < 0.001). The quality of the evidence was rated as moderate to low respectively.
