OBJECTIVES: The purpose
of this study was to evaluate the effect of periodontal health promotion and oral hygiene in children using a vibrating toothbrush.
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.
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.
These results suggested that vibrating toothbrushes designed for children can be helpful in promoting gingival health and improving oral hygiene.
