Clinical assessment of color stability and patient satisfaction for polished versus glazed lithium disilicate glass ceramic restorations

Aim: To evaluate clinically the color stability and patient satisfaction of polished versus glazed lithium disilicate glass ceramic restorations. Methodology: Twenty full coverage crowns were fabricated from IPS e. max press in posterior area. The patients randomly divided into two equal groups according to applied crown surface treatment. Group 1 (control group) 10 2 (intervention crowns. ΔE was measured using Vita easyshade evaluated through Visual Analogue Scale (VAS), immediately after cementation every months for one year. Data analyzed two-way ANOVA t-test. P ≤ 0.05 considered statistically significant. Results: results showed that polishing technique had a significant mean than glazing but both acceptable. Regarding follow up period time no effect on values. There also difference within each at different times. Conclusion: Although higher change glazing, it Therefor can be recommended as an alternative e.max
