Resin infiltration revolution in minimal invasive treatment – A review

The concept of the resin infiltration technique emerged for the very 1 st time in 1970 for the conservative management of initial smooth surface caries. The precept of resin infiltration is to halt the non-cavitated enamel by obstructing the subsurface porosity with resin, so-called caries infiltration. Infiltration of different types of resins into micropores is based on the approach that it will seal the diffusion pathways in enamel, further preventing demineralization without causing any harm to healthy tooth structure. Treatment of interproximal caries is always considered challenging due to a lack of access and the chances of unintentional removal of noncarious tooth structure. Recently, the introduction of resins on interproximal carious lesions proved that they can penetrate and seal the carious lesion, thus preventing the caries advancement.
