Effect of papaya extract (Carica papaya L.) on color changes of dental elements due to coffee extrinsic stain: An experimental laboratory study

Abstract

Abstract Aim: Papaya fruit was known to have papain enzymes that are able to break down the protein that makes up plaque, where extrinsic stains attach to teeth. The purpose of this study was to determine the effect of papaya fruit extract (Carica papaya L.) on color change of denture elements due to coffee extrinsic stain. Materials and Methods: This study was an experimental laboratory using pre-test and post-test designs. The specimens used in this study were elements of the maxillary central incisor (24 acrylic resin dentures) that have been stained by coffee, totaling 6 specimens per group. The specimens were immersed for 9 days in papaya fruit extract with a concentration of 40%, 60%, 80%, and 100%. Measurement of the specimen color change was done visually before and after soaking papaya extract using Shade Guide Vita 3D Master. Statistical test was carried out with a confidence level of 95%. Results: The results showed that there was a significant color change of the denture elements after soaking papaya extract. The value color dimension changes to be brighter, while the hue and chroma have no significant changes. In the comparison test of four treatment groups with extract concentration (40%, 60%, 80%, and 100%). This study showed that the 60% concentration group had a greater influence on the change in color dimension value. Conclusion: Papaya fruit extract can affect the color change of acrylic resin denture elements that have undergone coffee staining. Immersion of denture elements in papaya fruit extract with a concentration of 60% had a greater effect on color brightness.
