Abstract :

Objective: The aim of this in vitro study was to evaluate the effect of four different drinks ( Tea, Coffee, Cola, Distilled water) on the color of a microfilled composite resin light cure(Tetric A1, Ivoclar Vivadent) after immersion in these different drinks. Materials and methods: In this study, twenty resin–based composite specimens were prepared using a cylindrical mold measuring ≅2mm of thickness and ≅ 10mm of diameter. The composite specimens were light–cured for 40 s from both sides using a LED Radii at 1400 mW/cm2 and were randomized into 4 groups (n=5) according to the drinks : Tea, Coffee, Cola, And Distilled water (control solution). A digital spectrophotometer was used to evaluate the color changes at baseline and at 1 week after immersion in each solution. Results: At the end of the week, the group of samples stored in the Cola drink solution showed a color change that was obvious compared to the baseline color and was highly significant(P<0.001), while Coffee was next in color change and was significant(P=0.02). Tea group also showed color change and was significant (P=0.042). . Conclusions: We can conclude that drinking certain drinks may alter the color of the microfilled composite resin light cure. Cola has the higher effect, and then Coffee .While Tea has least effect.
