Comparison of the Effects of Different Toothpastes on the Micro Hardness of A Nano Hybrid Composite Resin – An in-Vitro Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
The aim of this study is to compare the microhardness of a nanohybrid composite resin after brushing with different toothpastes. Rubber moulds were used to prepare 80 composite specimens of 3M ESPE Filtek Z350. The specimens were light cured for 60 seconds, polished and cleaned in distilled water. Specimens were randomly divided into 4 groups of 20 specimens each and subjected to tooth brushing for 2 minutes twice daily with a motorised toothbrush for 30 days. In control group no paste was used with the toothbrush. In other 3 groups, Colgate Total Advanced Whitening toothpaste, Dabur Herbal toothpaste, and Himalaya Complete Care toothpaste were used. Vicker’s hardness test was performed for all the specimens. Data obtained in the study was subjected to statistical analysis using One-way Anova and Bonferroni test. There is a statistically significant difference in reduction of microhardness among all the groups compa Control > Himalaya > Dabur > Colgate. Bonferroni test showed that all the experimental groups showed significant reduction in micro hardness compared with the control group (P < 0.001 for all intergroup comparison) except group D (Himalaya). From the results it is evident that the effect of using the herbal toothpaste is almost similar to the effect of brushing on the composite surface without any toothpaste. While using non-herbal toothpaste a reduction in the microhardness was seen.
