OBJECTIVE The aim of this study was to assess the effect of energy and pulse repetition rate of the Er:YAG laser (2.94 microm) on dentin ablation ability and substrate morphology. BACKGROUND DATA Previous studies have demonstrated the ability of the Er:YAG laser for ablating dentin substrate. METHODS Fifteen crowns of molars were sectioned in four fragments, providing 60 samples, which were ground to expose dentin. Initial mass was obtained by weighing the fragments. Twelve groups were… CONTINUE READING
