Abstract
The efficacy of a commercially available toothpowder was compared with toothpaste in removing extrinsic dental stains. 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. 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). 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.
Highlights
Today, tooth discoloration is a major oral health concern and has been seen to affect the quality of life of an individual
While the majority of intrinsic tooth discoloration is due to ingested chemical or drug taken during teeth forming years; extrinsic stains are mostly related to the individual’s personal harmful practices which include smoking, tobacco chewing, beetle leaves, areca nut chewing and dietary habits. [1,2,3]
(4) Studies of chemical agents have focused on chelants, surfactants, and enzymes which could prevent or remove extrinsic dental stains. [5, 6] Various ingredients that could assist in the stainremoval process have been tested, but none of them have been indicated as a potential addition to food due to their toxicity
Summary
Tooth discoloration is a major oral health concern and has been seen to affect the quality of life of an individual. While the majority of intrinsic tooth discoloration is due to ingested chemical or drug taken during teeth forming years; extrinsic stains are mostly related to the individual’s personal harmful practices which include smoking, tobacco chewing, beetle leaves (paan), areca nut chewing and dietary habits. Scientists have compared chemical and mechanical approaches for stain removal. [4] Studies of chemical agents have focused on chelants, surfactants, and enzymes which could prevent or remove extrinsic dental stains. Controlled chemical, nonabrasive agents like chewing gum or mouthwash are being favored as a delivery vehicle for these stain removing ingredients. [7] This deposition can be reduced by effective oral hygiene practices, which focuses on toothbrushes and dentifrices. Studies like the present may answer these questions in order to guide consumers and professionals in using oral home-care products
