Evaluation of the color stability of different temporary restorative materials

This study aimed to evaluate the color stability of different temporary restorative materials in contact with staining solutions, as well verify which one presents highest resistance staining. In this laboratory study, five types were evaluated: self-curing acrylic resin, bis-acrylic light-curing CAD/CAM machinable, and 3D printed resin. Thirty samples each material produced a circular mold measuring 10 mm diameter 2 thickness. The divided into subgroups (n=10) immersed solutions: Coffee, Coca-cola®, distilled water (control). Color measurements carried out at baseline, 1, 7, 14 days using digital spectrophotometer parameters calculated according CIEDE00 system. change data subjected two-way ANOVA (temporary vs time) post-hoc Tukey test (α = 0.05). showed only comparing baseline vs. day, acceptability standard ΔE00 > 1.8. Thus, we concluded that there was difference already on first day immersion. addition, coffee solution variation when compared other solutions. Clinical applicability: Temporary restorations are widely used prosthetic treatments can remain mouth for considerable period. They responsible aesthetic function maintenance along rehabilitation process. they provide definitive prosthesis should assure comfort confidence patient. it is necessary these resistant present such does not compromise aesthetics during treatment phase.
