Aim and objective: To test the colour stability of acrylic denture base material that had been manually blended and rationed before being submerged in artificial saliva.
Materials and Methods: The study groups consisted of group 1 which included handmixed specimens and group 2 comprising pre-measured specimens. The color stability values of these specimens were obtained from Konika Minolta Spectrophotometer. Both the specimens were immersed in artificial saliva for 1 week and color stability were again obtained and compared using independent T-test.
Results: It showed that color stability values obtained from the spectrophotometer were better in pre-measured specimens. However, the obtained p value was 0.05 which makes the study non-significant.
Conclusion: Pre-measured samples provide better color stability in the long run of the denture.
Clinical Significance: Measured values of polymer and monomer in the cold cure denture base material during manipulation of the material provide better color stability signifying its long run.
