Abstract: (10 Views) |
Background: Various chemical solutions have been suggested for disinfecting dentures. However, the dipping method may influence the properties of the acrylic denture base, such as strength and color. This study aimed to compare and evaluate the color change of the heat-cured acrylic denture base subjected to the dipping method using antimicrobial extracts of ginger, myrtus, and chamomile plants.
Materials and Methods: This laboratory experimental study involved the preparation of 80 acrylic denture base samples, each measuring 3.3 × 10 × 65 mm. The samples were divided into four groups(n=20). Pure extracts of ginger, myrtle, and chamomile were prepared. A colorimetric test was initially conducted on all samples. The specimens were then immersed in their assigned solutions or in distilled water as a control for a duration of 10 days, with each day consisting of three immersions, each lasting for 15 minutes. Following the 10-day treatment period, a subsequent colorimetric test was performed. The colorimetric measurements were performed utilizing a spectrophotometric device, in accordance with the CIELAB color system. Data were analyzed by a one-way ANOVA test (α = 0.05).
Results: The four groups under study exhibited no significant difference in the mean discoloration value of the acrylic denture base (p=0.200).
Conclusion: Results of our study showed that extracts of ginger, myrtus, and chamomile did not alter the color of the denture material within the given time.
