Aim and objectives: To compare the effectiveness of the stain removing property of the whitening toothpastes (silica [Colgate Visible White], silica, papain and bromelain [Whitospark], and silica and calcium carbonate [Snowdent] containing toothpastes) on extrinsic dental stains and to assess the lasting of tooth whitening effect produced by the whitening toothpastes. Materials and methods: It is a randomized, concurrent parallel arm, non-invasive, controlled trial designed to compare the effectiveness of the whitening toothpastes on reducing extrinsic dental stains. Parametric t -test was used. Results: A statistically significant difference can be seen between Groups A and B, Groups B and C, and Groups B and D. Maximum mean and percentage reduction was found in Group B at the end of the second month in stain extent and intensity. A statistically significant difference was seen between subgroups B1 and B2. Maximum mean and percentage reduction was found in subgroup B1 at the end of the fourth month in stain extent and intensity. Conclusion: Silica, papain, and bromelain containing toothpastes (Whitospark) show effectiveness on reducing extrinsic dental stains. [ABSTRACT FROM AUTHOR] |
