The purpose of this investigation was to determine if statistically significant differences existed in the gingival health of subjects who brushed with a rotary electric toothbrush (Rota-dentR when compared to a conventional toothbrush (Oral B-35R). A randomized, two group research design was employed using forty subjects. At baseline and at two week intervals for six weeks, gingivitis and supragingival dental plaque were measured by the Loe and Silness Gingival Index and the O'Leary Plaque Index, respectively. Multivariate analysis revealed that the Rota-dentR was superior to the conventional toothbrush in reducing dental plaque accumulation and equally effective at reducing gingival inflammation. When area specific multivariate analysis was performed, superiority of the Rota-dentR at reducing gingival inflammation in the anterior region was found. Results suggest that the Rota-dentR is a safe and effective home care device when utilized properly.
