Comparative Evaluation of the Effect of Water on Three Different Light Cured Composite Restorative Materials: An In Vitro Study
Journal Title: Scholars Academic Journal of Biosciences - Year 2015, Vol 3, Issue 11
Abstract
Abstract: Aims and Objectives of current to Evaluate the weight gain in three different light cured composites occurs due to water absorption. The composite restorative materials selected for this study included a micro-fine hybrid (Filtek Z 250 XT) and two nano-filled composites (CERAM X duo and FILTEK Z 350). Ten specimens of each material were fabricated with each composite material. Group A: Filtek Z 350, Group B: Filtek Z 250 XT, and Group C: CERAM X Duo. Specimens were stored in 10 ml distilled water in test tubes, and then placed in an incubator at 37˚C for six weeks. The weight changes of these specimens were measured daily for the first week, and later, once a week, for the next five weeks, by using an electrical analytical balance. The statistical analysis of the results showed FILTEK Z 250 showed the maximum amount of water absorption in the first week. However, FILTEK Z 350 showed the maximum amount of water absorption from the second week to the sixth week, as compared to CERAM X Duo and FILTEK Z 250.All composite restorative materials absorb some amount of water. The water absorption of the composite may decrease the physical and mechanical properties of the composites hence, it is necessary to consider the type of the material before starting treatment. Keywords: Micro-Fine Hybrid; Nano-Filled Composite; Water sorption; Electrical Analytical Balance.
