Abstract
Objectives: The present study aimed to comparatively evaluate the color variations
of three different commercially available provisional restorative materials, using
computerized spectrophotometry before and after immersion in artificial saliva and three other different mouth rinses Materials and Methods: One hundred and twenty samples (40 of each material; Revotek LC, TempSpan, Jet tooth shade) were prepared in the form of discs (10 mm diameter and 2 mm thickness), and these samples were randomly
divided into 4 subgroups for the solutions; chlorohexidine, Tantum V and Oracin mouth washes and artificial saliva(n=10). The discoloration solutions were changed twice a day throughout the three weeks. The color values (L*,a*,b*) of each specimen
were measured before and after exposure with a Reflective spectrophotometer. Results: regardless to staining solutions, it was shown that TempSpan material group recorded the highest color change mean value (3.68±0.39ΔE) followed by Revotek LC material group mean value (1.56±0.27ΔE) while Jet tooth shade material group recorded the lowest color change mean value (1.4±0.46 ΔE).on the other hand, A. saliva
recorded the highest color change mean value (2.78±1.2 ΔE) followed by Tantum V solution mean value(1.72±0.31ΔE) then Oracin solution mean value (1.5±0.4ΔE) while CHX staining solution recorded the lowest color change mean value (1.32±0.4 ΔE). Conclusions:1- All the bis-acryl resins and PMMA-based provisional materials showed clinically perceptible color changes after exposure to oral rinses. 2- Among the three provisional restorative materials, Tempspan was found to be significantly the least color stable material and the least stain was taken up by Jet. 3- There were no significant differences between the discoloration effects of Tantum V, Oracin and Chlorohexidine mouth washes on the three tested provisional materials.
