Fluorescence-aided caries excavation (FACE), caries detector, and conventional caries excavation in primary teeth.

Purpose: The purpose of this paper was to compare the ability of fluorescence-aided caries excavation (FACE) to remove infected dentin in primary teeth with that of conventional methods.

Methods: Sixty-six extracted carious primary teeth were divided according to lesion size into 3 groups of 22 teeth. Caries excavation was carried out with a slow-speed handpiece and round burs for all groups.
