Evaluation of Restorative Materials Translucency Properties

The aim of this study was to compare the translucency values of different restorative materials before and after accelerated ageing. In the present study, 84 specimens (n=7) were made of two different composite resin material, flowable composite, hand mixed glass ionomer cement, capsule glass ionomer and compomer with shade A3. All specimens were made with a thickness of 2 mm and 10 mm diameter. Translucency parameter (TP) values of the restorative materials were evaluated before and after UV accelerated aging, using a colorimeter (ShadeEye Exe, Shofu, Japan). Statistical analyses were performed with Tukey HSD and Paired Sample T-Test (p 0.05). Composite resin material (GC composite) showed the highest TP value (9,051); while capsule glass ionomer showed the least (1,568). UV aging significantly affected all restorative materials, as TP values decreased after aging process. After aging (GC composite) showed the highest TP value (7,941); while hand mixed glass ionomer showed the least (0,982). Except flowable composite and compomer; hand mixed glass ionomer and capsule hand mixed glass ionomer there were statistical differences of TP values between restorative materials. (p 0,05). TP values of the restorative materials vary with each other. Aging process decreases the TP values of restorative materials and causes them to get more opaque.
