"It doesn’t matter what lost what matter is what remains” R.D.T (Remaining Dentin Thickness): A review

Abstract

Thickness of residual dentin following cavity preparation or intra-radicular procedures is the factor as it affects the pulp vitality, permeability of tooth, and also fracture resistance of the root. Although, various methods were described to calculate the residual dentin thickness in vitro over the decades of research the brief description about different methods for calculating it is not considered, and also methods to measure RDT in vivo is never discussed. Thus, this review discusses various methods of calculating RDT in patients as well as in the laboratory.
