Extrinsic stain removal with a toothpowder: A randomized controlled trial.

OBJECTIVES
The efficacy of a commercially available toothpowder was compared with toothpaste in removing extrinsic dental stains.


METHODS
In this single-blind, randomized controlled trial, 77 volunteers were included from a residential professional college. All study subjects (control toothpaste users and test toothpowder users) plaque control measures. All study subjects were instructed to rinse with 5 ml 0.12% chlorhexidine mouthwash for 1 minute, twice and one cup of double tea bag solution three times daily for three weeks. Subjects were randomized into test (n=36) and control (n=36) groups. Toothpaste (control) and toothpowder (test) was used for two weeks to see the effects on removing stains on the labial surfaces of 12 anterior teeth. For measuring dental extrinsic stains Lobene Stain Index (SI) was used.


RESULTS
The amount of stain following the use of toothpaste and toothpowder was more controlled with the experimental toothpowder. For all sites combined, there was evidence that the experimental toothpowder was significantly superior to toothpaste in reducing stain area (p<.001), stain intensity (p<.001) and composite/product (area × intensity) (p<.001).


CONCLUSION
Stain removing efficacy of toothpowder was significantly higher as compared with toothpaste. A toothpowder may be expected to be of benefit in controlling and removing extrinsic dental staining.
