Bonding to caries affected dentine

Carious dentin consists of two distinct layers: an outer bacterially infected layer of dentine, and an inner layer of affected dentine [1]. The caries-infected layer (CID) is highly demineralized, physiologically unremineralizable and contains irreversibly denatured collagen fibrils with a virtual disappearance of cross-linkages [2,3]. On the other hand, the caries-affected layer (CAD) is uninfected, partially demineralized and physiologically remineralizable [2 –4]. High porosity and exposure of collagen fibers along with a decrease in the surface energy are seen in the inter-tubular CAD [2–4].
