Objectives: The purpose of this study was to evaluate the effect of periodontal health promotion and oral hygiene in children using a vibrating toothbrush. Methods: Forty-seven volunteers aged between 7-15 years participated in this study at local care centers from January to February 2013. A vibratory toothbrush for children was designed with the bristles operating on a self-vibration system that separated the head-neck part of the toothbrush from the handle. The toothbrush was designed with the aim of massaging the gingiva and reducing gingival inflammation. The papillary marginal attachment (PMA) index and O`Leary plaque index were measured by oral examinations before and at 4 weeks after brushing with the vibrating toothbrush. Results: The PMA index and O`Leary plaque index were reduced from 39.20 to 25.42 (P<0.001) and from 5.56 to 2.78 (P<0.001), respectively. Conclusions: These results suggested that vibrating toothbrushes designed for children can be helpful in promoting gingival health and improving oral hygiene.
