About

This study compared the removal of dental biofilm between soft and medium toothbrushes. The patients refrained from performing mechanical or chemical plaque control for 96 hours to allow dental biofilm accumulation on the tooth surfaces. After the period of dental biofilm formation, the quadrants were randomized and the participants brushed different quadrants with soft and medium toothbrushes, with or without dentifrice. The plaque indices were analyzed by a blinded examiner before and after toothbrushing. The 2Tone was used for plaque disclosure and analysis was performed by the Quigley-Hein index modified by Turesky et al. (1970).

25 participants in 2 patient groups

toothbrush

Active Comparator group

Description:

a randomization was performed in which the participants were allocated to the following experimental procedures: Two quadrants (1 and 3 or 2 and 4) with medium toothbrush Two quadrants with soft toothbrush. All procedures were performed using the same dentifrice. Each quadrant was brushed for 30 seconds by the participant without specific instructions on the technique, under supervision of the person in charge of the randomization.
