摘要: The aim of this study was to investigate the effects different direct current intensities on dentine bonding effectiveness Clearfil S(3) Bond and cell viability human dental pulp cells (HDPCs). Thirty-five-third molars were sectioned ground provide flat surfaces. applied under conditions for 30 s then resin composite built up. Specimens processed microtensile bond strength (µTBS) testing nanoleakage investigation using scanning electron microscopy. Primary HDPCs isolated from premolars stimulated with electric s. Then, tested 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. bonded application electrical 50, 60, 70, 90 µA exhibited a significant increase in immediate µTBS compared all other groups. Bonded interfaces prepared electrically assisted showed reduced interfacial upon Electric application, 20 70 µA, had no effect HDPCs. This provides further evidence its future clinical use.
