ABSTRACT

Introduction: Although the artificial teeth seem to be more inportant, the change of color in the denture base has the same value regarding several components, one of them is color stability. Color stability is an important parameter for the complete denture wearing patients.
Aim: of this study was to evaluate the color stability between two types of dentures: 1. Dentures constructed with injection molding technique and 2. Dentures constructed with compression molding method.
Materials and methods: The dentures were stored in three different solutions: artificial saliva+tea, artificial saliva+coffee and artificial saliva.
Results: The color change was determined using a spectrophotometer. The group of dentures made of acrylic resin with the injection molding method showed less coloration compared to the dentures with the compression molding method. The solution that caused more coloration was tea.
Conclusion: Based on this study it can be concluded that the dentures which are constructed with the injection molding technique shower a higher grade of color stability compared to the dentures constructed with compression molding technique.
