Effects of Disinfectants Used for COVID-19 Protection on the Color and Translucency of Acrylic Denture Teeth
Purpose: This study investigated the color and translucency changes of denture teeth after immersion in disinfectant solutions. Material and Methods: Ten denture teeth (Optostar/Heraeus Kulzer) were immersed in nine different solutions (ethanol 78%, 2-propanol 75%, NaOCl 1%, H2O2 0.5%, glutaraldehyd...

Summary: | Purpose: This study investigated the color and translucency changes of denture teeth after immersion in disinfectant solutions. Material and Methods: Ten denture teeth (Optostar/Heraeus Kulzer) were immersed in nine different solutions (ethanol 78%, 2-propanol 75%, NaOCl 1%, H2O2 0.5%, glutaraldehyde 2.6%, chlorhexidine 0.12%, povidone-iodine 1%, Listerine Naturals, distilled water) for 3 min to 180 min. L*, a* and b* values were measured before and after their immersion with a contact colorimeter (FRU-WR18/Shenzhen Wave Electronics) over a white and black background, and ΔΕ*ab, ΔΕ00, ΔΤPab and ΔTP00 differences were calculated from baseline measurements. Two-way rmANOVA was used to analyze the data for significant differences among solutions and immersion times at α = 0.05. Results: ΔΕ*ab and ΔΕ00 values were significantly different only across solutions (p < 0.001), with mean differences from 0.24 to 1.81 ΔΕ*ab or 0.12 to 0.93 in ΔΕ00 units. TPab or TP00 translucency parameters showed no significant differences among intervals or solutions (p > 0.050). The mean changes ranged from −0.43 to 0.36 ΔTPab units, and −0.22 to 0.27 in ΔTP00 units. Conclusions: Most of the solutions had no significant effect on the color of teeth compared to the water group. Chlorhexidine 0.12%, glutaraldehyde 2.6% and Listerine produced significant color changes, especially at 180 min. The translucency of teeth was not affected by the solutions, regardless of the type and immersion time. |
