A comparison of two electric toothbrushes with respect to plaque removal and subject preference.

Abstract

Plaque levels were significantly reduced by both toothbrushes (P = 0.001), but the efficacy of the 3D electric toothbrush was significantly greater than that of the sonicare toothbrush (P = 0.001) for all comparisons. Plaque reduction was particularly marked in the interproximal areas, reaching 87% with the 3D product, compared with 68% for sonicare (P = 0.001). In the responses to the questionnaire, the majority of subjects stated that they preferred the 3D toothbrush (88% vs 12%), mainly because of the smaller size of the brush, ease of control and overall maneuverability.
