SEM study on dentin/resin interface in primary teeth

Dentinal adhesives Excite, Single bond, Prime bond, Prompt-L-pop Adper, Xeno III and AdheSe were applicated into class I cavities preparated into extracted primary teeth and they were restored with EvoCeram. The teeth were prepared for investigation under scanning electron microscope using Epovac and Struers Tegra polishing system. There was no substantial difference in morphology of the dentine/resin interface between the techniques studied. This fact may be of importance in the restoration of primary teeth because the number of steps and the procedure duration can be significantly reduced.
