Evaluation of Color Stability of Finix, Super Berelian and Betastar Acrylic Denture Teeth in Effect of Dentipur Denture Cleaner

Background: None of the previous studies have evaluated acrylic resin teeth used at the Dentistry Department of Hamadan University of Medical Sciences (brands: Finix, Super Berelian, and Betastar). Methods: A total of ۲۵۲ samples containing acrylic resin teeth used at Hamadan Dental School were studied. Finix, Super Berelian, and Betastar were selected in the same mold and in ۳ colors. (A۱, A۲, A۳). The samples of each brand were studied in ۲ groups. The first group was placed in a solution of Dentipur cleaner for ۷ days. The second group of specimens was placed in ۱۰۰ mL of distilled water. Data were recorded in the CIELAB system, and the spectrophotometer obtained values of ΔE, ΔL, ΔH, and ΔC. Then, changes in each of the components were obtained before and after the intervention. Results: The results show that the changes in the parameters of ΔE, ΔL and ΔC were statically significant when comparing the ۲ groups (P < ۰.۰۵) and only in terms of the parameter ΔH, the changes were not statically significant (P > ۰.۰۵). The changes made in the variables were significantly different from the initial color of the samples in the factors ΔE, ΔL and ΔH (P < ۰.۰۰۱) but in terms of the parameter ΔC, the changes were not statically significant (P > ۰.۰۰۱), and the changes in the variables were significantly different from the sample brand in all the measured factors (P < ۰.۰۰۱). Conclusions: Dentipur denture cleaner creates more color change than distilled water in acrylic teeth. The changes in most variables were associated with the shade of acrylic teeth, and in the teeth with brighter shade, the color change was higher compared with a darker shade. Super Berelian teeth have the most color change and Betastar teeth showed the lowest change in color. Delta E value was clinically acceptable.
