COMPARATIVE EVALUATION OF SORPTION AND SOLUBILITY OF ESTHETIC RESTORATIVE MATERIALS IN VARIOUS MEDIA - AN INVITRO STUDY

Abstract

Aim: The aim of the study was to compare and evaluate the sorption and solubility values of Beautifil II LS, Cention N, FiltekZ250 restorative material in various liquid media such as coffee, coca-cola, medicated syrup.

Method: A total of sixty samples of restorative material were prepared using a metallic mould and divided into three groups of twenty samples each (n=20); Group I: Beautifil II LS, Group II: Cention N ,Group 3: FiltekZ250.The weight before immersion in the test media (M1) was measured using digital analytical scale. Each group was subdivided into four subgroups (n=5) based on the test media they were immersed in; Subgroup 1: Coffee, Subgroup2:coca-cola, Subgroup 3: medicated syrup, Subgroup 4: Distilled water (control group). Five specimens each of the restorative material were kept immersed in the test media for seven days. The weight of the samples after immersion (M2) in the test media after seven days and the final dry weight of the samples (M3) were measured. Sorption and solubility of these restorative materials were calculated using ISO guidelines. The data obtained was statistically analysed using one way ANOVA Test.

Result: Among the media tested coca-cola showed both sorption and solubility values greater than the other medias. Beautifil II LS was found to have highest sorption and solubility values than other two restorative materials.

Conclusion: The composition of material and low pH carbonated drinks can influence the properties of tooth colored restorative materials.
