The purpose of this study is to evaluate the efficacy of a lithium battery toothbrush in improving gingivitis. The experimental toothbrush had a 3-volt lithium battery installed in the handle and gave a small electrical charge to the teeth or gingival tissue. The control toothbrush was completely the same but without the battery against the experimental one. A double blind study was conducted for 16 weeks on 26 volunteer students aged 18-24. Gingival conditions of subjects were assessed by probing depth and according to the modified Papillary Bleeding Index. The modified Papillary Bleeding Index of experimental groups showed a significant decrease, although probing depth of experimental groups showed a similar tendency to that of control groups. This finding suggests that improvements in gingivitis might be expected through charging gingival tissue electrically in addition to mechanical plaque removal by toothbrush itself.
