An in vivo study of glass ceramic (Dicor®) inlays Preliminary report

Abstract

For the purpose of evaluating the clinical quality of glass ceramic (Dicor®) inlays 15 patients with 37 inlays were examined 1 to 22 months after placement. In addition to certain periodontal variables, the inlays were rated by two independent examiners using the California Dental Association (CDA) quality evaluation system. The results of the present study showed that dental plaque was seen less often on proximal surfaces with inlays than on homologous proximal surfaces. Three patients reported hypersensitivity of the dental pulp. The examination using the CDA criteria showed that 54% of the inlays had a slight color mismatch, and slightly roughened surfaces were occasionally seen (35.5%). In nearly 30% of the inlays there was visible evidence of ditching along the margins. At present, no judgement can be made about the longevity of ceramic inlays.
