title: Clinical evaluation of plaque removal with a double-headed toothbrush.
abstract: A blind, two-way, crossover clinical trial, completed by 44 adult subjects, instructed in specific oral hygiene techniques, was carried out to compare the effectiveness of plaque removal between a new Scandinavian double-headed toothbrush and a popular single-headed brush, each used for one week. The results showed that the double-headed brush was significantly more effective in removing plaque overall than a conventional brush. The effect was most evident on all lingual surfaces, especially in the lower arch and molar regions. It was also particularly pronounced when the double-headed toothbrush was allocated for use in the 2nd week of the study. There was no significant difference in the cleaning ability of the 2 brushes on the buccal surfaces of the teeth.
