Overview

The aim of this study was the observation of the gingival metal pigmentationsdeveloped after application of metal prosthetic restorations made of the alloys usually used inthe Czech republic. By 23 patients (11 male and 12 female) the occurrence of the gingival metalpigmentations and the type of the dental metal alloys were examined. It was found that gingivalpigmentations developed most frequently by the teeth without pulp which were treated withconservative and prosthetic methods. Number of the gingival pigmentations positively corre-lated with the number of the dental metal alloys used for prosthetic restorations. For thisreasons is necessary to be carefully with the choice of dental metal alloys. Carbon posts and"metalfree" materials can be considered as perspective materials for prosthetic restorations.

Key words:
metal pigmentation – gingiva – prosthetic alloys
