Effect of Dietary Drinks on the Microhardnessof Two Nanocomposites:An in- Vitro Study
Journal Title: Saudi Journal of Oral and Dental Research - Year 2017, Vol 2, Issue 6
Abstract
Abstract: The aim isto determine the effect of two dietary drinks Coca Cola and Tropicana orange juice on the surface hardness of two aesthetic nanocomposite materials.Materials and methods: The materials included nanocomposite materials ShofuBeautifil II and Estelite α- supranano composite. A sample size of 120 specimens of 5.5mm × 3 mm in dimension of each restorative material was prepared . The discs were divided into 2 groups of 60 specimens each and each subgroup of 20 samples each .The discs were immersed in different beverages in time intervals of 1 hour,1 day and 1week . Surface hardness tests were performed before immersion and at time intervals of 1 hour,1 day and 1 week intervals. Statistical analysis used was one way ANOVA.Results: Exposure to Coca Cola and Tropicana orange juice reduced the hardness of both the nanocomposites with Coca Cola showing greater reduction in hardness between the two with p<0.05. ShofuBeautifil II showed greater reduction in hardness than Estelite α-suprananoat all time intervals.Conclusion:Estelite α-supranano showed better results compared to ShofuBeautifil II .Clinicians should therefore judiciously decide which material will be better for patients taking into consideration their dietary habits and lifestyle. Keywords: Nanocomposites, beverages, immersion, hardness.
