Surgical Management of Caries Lesions: Selective Removal of Carious Tissues

Abstract

Traditionally, before placing a restoration, excavation of tissues affected by caries was recommended. The goal was to have all walls of the cavity on sound, hard dentin, even when at risk of pulpal exposure. Current understanding of the caries process indicates that preserving tooth structure can lead to better long-term outcomes. Selective caries excavation refers to preserving tooth structure by delineating excavation in the pulpal and axial wall according to lesion severity and depth as well as pulpal health while keeping all cavity margins on sound tooth structure. Compounding evidence indicates that when a good marginal seal is present, the lesion will arrest.
