The cleaning efficiency of different toothbrushes in children

A 2-way, blind, cross-over study was carried out to compare the plaque-removing effects of a double-headed toothbrush with a popular single-headed flat toothbrush in 34, 11- to 13-year-old boys. Both brushes were used with a modified Bass technique for 3 weeks each. The results of the study indicated that lingually, the double-headed brush was superior to the single-headed brush whilst bucally no difference was found. Although the overall plaque-removing effect of both brushes was similar, 95% of the children preferred the single-headed brush to the double-headed brush.
