Abstract

The growing demand for an enhanced esthetic smile has led to the development of whitening toothpaste in the market. The whitening effects are usually achieved by the incorporation of bleaching and abrasive components. An ideal whitening toothpaste should remove stains effectively, with minimal effect on tooth structure. Materials and Methods: Twenty-four extracted human maxillary anteriors were randomly and equally divided into three groups, and each was subjected to tooth brushing using different toothpastes. Surface roughness was estimated using the surface roughness tester, and microhardness was estimated using the Vickers hardness tester at baseline and after 3 months. Results: In the activated charcoal group, there was an increase in the surface roughness from baseline to 3 months, which was found to be statistically significant. However, no statistically significant difference in surface roughness was found in the other groups. With respect to microhardness, the activated charcoal group showed a statistically significant difference from baseline to 3 months, unlike other groups, which did not show statistical significance. Conclusion: This study showed that whitening toothpaste containing charcoal significantly increased surface roughness and microhardness.
