Objective: The aim of this in vitro study is to compare the color stability of 3 different heat pressed all-ceramic crown systems [creation press, injectable pressable system (IPS) empress and finesse].
Materials and Methods: A total of 140 crowns were prepared for 7 groups (n=20) on metal dies, representing the maxillary right central incisor. Colors were measured before and after a total of 500 thermal (5 and 55°C) container baths. Measurements of color change values were performed by a chromameter. One-way analysis of variance was used to compare the data. Results: The average color change of the tested groups ranged from 0.671 to 1.513. Analysis revealed that there were no significant differences in the mean color change values among the groups (p>0.05). Statistical analysis shows that all ceramic groups have the same, nearly equal color change values. Conclusion: Color stability of all heat pressed all-ceramic crown systems and metal-ceramic systems are not influenced by 24 hour storage and 12 seconds 500 cycles of 5 and 55°C distilled water thermal process. |
