Abstract

Purpose: To evaluate the influence of two different surface treatments on the stainability and color change of ceramic restorations. Materials and Method: Veneering lithium disilicate was used to fabricate standardised discs (n=60). These discs were abraded using a red band diamond abrasive. Samples were divided in three groups. Surface Roughness (Ra)values before and after the surface treatment were calculated using a surface profilometer. These specimens were further subdivided into 2 subgroups with 10 samples each. Colour change (∆E) values were calculated at 6, 12, 18 and 24 days. Results: Independent t test for the groups Polish and Reglaze showed a significant difference (p = 0.003). One way ANOVA for the Green tea group showed a significant difference (p = 0.007) at 12 days between Control and Polish and Control and Reglaze. One way ANOVA for the Turmeric group showed a significant difference at 12, 18 and 24 days. Conclusion: For increased periods of clinical usage corresponding to increased immersion times, reglazing was necessary to prevent stain absorption especially against Turmeric.
