Abstract

Purpose: The purpose of the current study was to compare the effect of different surface treatments on the light transmission and adhesion of two types of posts. Materials and Methods: Two groups of glass Fiber post specimens (Glassix) Conventional glass fiber post and (Glassix plus) Translucent glass fiber posts were prepared 10 mm length and 1.5 mm diameter (n = 40). The groups were classified into four sub groups (n=5): Group 1: Did Not receive any treatment; Group 2: treated with hydrofluoric acid (HF) 9.6%. Group 3: treated with 110 μm Al2O3; Group 4: exposed to (Er-Cr:ySGG) laser. The light transmittance of the specimens was compared using a spectrophotometer and bond strength measured for each post at (middle-apical-coronal) using universal testing machine. Results: there was no significant effect of surface treatments on light transmittance of posts (P > 0.001) control group had the highest values while the HF group had the lowest value. Surfaces treatment had significant effects on bond strength of posts (P < 0.001) translucent post had bond strength higher than conventional post. Conclusion: Application of surface treatments had no significantly effect on the translucence property of fiber posts but significatly Affected bond strength.
