Purpose: The present invitro study was conducted to evaluate and compare the colour stability of four commercially available provisional restorative materials.
Methods and Material: In the present study a customized 3 piece brass mold with the middle section of (2mm thick & 7mm diameter) was used to fabricate auto polymerizing bis-acryl resin specimens. 30 samples were prepared for each group and checked for colour stability in coffee and tea. One way Analysis of variance (ANOVA) and post hoc test was done for inter comparison between groups.
Results: The findings from the study show the mean reflectance value of structure 2 SC was 22.839 followed by Systemp c & b with 21.699, Integrity with 21.186 and Protemp with a mean of 21.036.
Conclusion: Structure 2 Sc (Voco) displayed the more color stability and followed by system c & b and Integrity and protemp 4.
