Intratubular crystal deposition and remineralization of carious dentin.
An analysis of accumulated experimental results, the mechanism of intratubular crystal deposition in the transparent layer and remineralization of the matrix of carious dentin has led to a more rounded concept and understanding of dentin caries relevant to clinical practice. The transparent layer of carious dentin is not sclerotic but is part of the demineralized softened dentin. The crystal precipitation in the tubules is an intermediate product in a slow demineralization process. Physiological remineralization occurs in matrix of the inner carious dentin which has crossbanded collagen fibers and odontoblastic processes. The overall process of dentin caries is re-examined and described in view of these concepts.
