A clinical evaluation of extrinsic stain removal: a rotation-oscillation power toothbrush versus a dental prophylaxis.
OBJECTIVE
To assess extrinsic stain removal efficacy of a power toothbrush and a dental prophylaxis followed by the use of a standardized American Dental Association (ADA) reference manual toothbrush.


METHODS
This was a randomized, positive-controlled, examiner-blind, parallel group, two-week study. A Lobene stain examination was performed at baseline. Subjects were randomized to one of two treatment groups: Group 1: Oral-B Vitality Pro White power toothbrush or Group 2: Subjects receiving a dental prophylaxis then using a standardized ADA reference manual toothbrush. Subjects were instructed to brush their teeth with the assigned toothbrush and a fluoride dentifrice in front of a mirror twice per day for 2 minutes. Stain was reassessed following 2 weeks of brushing.


RESULTS
A significant reduction (p <0.001) in mean Lobene composite scores after 2 weeks was found for Group 1 (90.6%) and Group 2 (94.4%). Both groups also showed a significant reduction (p <0.001) in extent and intensity scores. There was no significant group difference in reduction in mean Lobene composite scores (p>0.1).


CONCLUSIONS
The Oral-B Vitality Pro White power toothbrush showed effective stain removal at a level similar to receiving an oral prophylaxis followed by the use of an ADA reference manual toothbrush.


CONCLUSIONS
In this small study the Oral-B Vitality Pro White power toothbrush achieved statistically significant stain removal between dental visits.
