Abstract
Introduction: Glass ionomer cement is a restorative material used in dentistry as a filling material and luting cement. Nowadays many consumers have started using natural toothpaste in order to avoid synthetic and artificial products. The aim of this study is to compare the surface roughness of two commercially available glass ionomer cements after subjecting them to brushing simulation with herbal and fluoridated toothpaste.
Materials and Methods: Glass ionomer cements of two different brands (D- tech and gold label) were moulded into small discs of custom sizes. Their surface roughness before subjecting them to brushing simulation was recorded using Mitutoyo SJ 310 stylus profilometer. Then the glass ionomer cement pellets were mounted on die stones. 4 samples of D-tech and 4 samples of gold label were taken. The mounted samples were placed in a tooth brush simulator (ZM3.8 SD Mechatronik). The samples were subjected to 30000 cycles of brushing with standard and herbal toothpastes. After brushing simulation the GIC samples were again checked for their surface roughness using the stylus profilometer.
Results: The values were recorded and analysed in the SPSS software. The obtained results from the one way ANOVA test were depicted in the form of tables and graphs. Surface roughness of D-Tech Colgate group GIC samples was increased after brushing simulation. The p-value is 0.469 < 0.05, hence statistically not significant.
Conclusion: From the results obtained we can conclude that gold label brand glass ionomer cement showed less surface roughness when compared to D tech brand glass ionomer cement after brushing simulation with herbal and fluoridated toothpaste.
