Clinical Criteria for Caries Dentin Removal with Carisolv™ System

Abstract

The purpose of this study was to evaluate the efficacy on caries dentin removal of caries detecting dye (Caries Check)in combination with DIAGNOdent® at dentin after Carisol™ treatment, compared with conventional methods. Twenty human extracted teeth with shallow caries on tooth crown and another twenty with deep caries were chosen and divided into two groups. After Carisolv™ treatment, existence of residual caries was detected by traditional ways: visual inspection with hardness checking or by Caries Check with DIAGNOdent®. After caries removal and conventional filling of prepared cavities with light-curing resin, samples were soaked in rhodamine B, and then bisected to be examined by stereoscopy and SEM. As a result, 20% of shallow caries and 50% of deep ones were dyed with Caries Check in the traditional inspection groups. Marginal leakage test and SEM examination showed traditional inspections had led to the formation of a gap between dentin and filled resin, and there was a significant difference in deep caries group, compared by Caries Check with DIAGNOdent®. It was suggested that to judge caries dentin removal using Carisolv™, the combination of Caries Check and DIAGNOdent® is required. Especially, at deep caries dentin removal, it is thought that this new judgment after Carisolv™ treatment is necessary.
