Electric current is used to promote wound healing in medical field. The present study examined the effect of electric stimulation by the manufactured toothbrush on gingival tissue in both the animal and clinical study. In the animal study, 50uA and 100uA of electrical stimulation exhibited a lower density of collagen in gingival tissue than 0uA of stimulation, indicating the effect of remodeling in periodontal lesions. The clinical study showed that electrical stimulation combined with mechanical vibration effectively induced the % of sited with bleeding on probing
