Evaluation of Penetration Depth and Caries Progression using Resin Infiltrant in Natural White Spot Lesions of Primary Molars.

Abstract

Management of white spot lesions (WSLs) using resin infiltrants, like ICON®, is a novel technique that emphasizes the concept of minimally invasive dentistry. Evaluate penetration depth and its effect on caries progression of ICON® in natural WSLs of primary molars. A total of 30 human primary molars with natural WSLs were selected. A total of 15 samples each were randomly selected to evaluate penetration depth and caries progression. To evaluate penetration depth, lesion surfaces were sectioned into two halves, wherein one half served as control, while the other half received ICON® infiltration treatment. To evaluate the effect on caries progression, samples were sectioned into two halves, wherein one half served as a control to its experimental counterpart, which received ICON® infiltration. The initial depth of the subsurface lesion (baseline data) was measured, and all the sample subsets underwent pH cycling. Confocal laser fluorescence microscope (CFLM) evaluation was performed, and penetration depth was assessed using a laser scanning microscopy (LSM) image reader, while caries progression was evaluated using PhotoScape® software. ICON® resin infiltrant penetrated to significant depths into the WSLs (p < 0.001) and demonstrated significant inhibition of caries progression (p < 0.001). The novel technique using ICON® could be an invaluable tool in the management of WSLs in primary teeth. Babu G, Mallikarjun S, Vijayan V, et al.
