The impact of soaking heat-cured acrylic resin’s surface roughness in turmeric tamarind solution

Background: Dentures are a solution for the issue of tooth loss. Heat-cured acrylic resin is a common base material for dentures in dentistry. When exposed to acids frequently, the acrylic plate's surface becomes rough. Because of their health advantages, turmeric tamarind herb is commonly taken. Turmeric rhizomes and tamarind fruit are used to make herbal turmeric tamarind. The citric acid in tamarind fruit reduces the surface tension of acrylic resin that has undergone heat curing, increasing porosity and roughness. Materials and Method: 24 heat-cured acrylic resin plates that were pretested and divided into two groups of packed and unpackaged tamarind turmeric herbs were used in the laboratory experiment. The pH value of each group was measured. Each group's 12 samples were soaked for 1, 3, 5, or 7 days before the roughness was gauged and examined. Result: An analysis of the data using the two-way ANOVA test revealed a significant difference between the length of the immersion and the surface roughness of the heat-cured acrylic resin of 0.023 (0.005). However, the difference between the packaged and unpackaged turmeric tamarind groups was just 0.131 (> 0.005). Conclusion: The harshness of the heat-cured acrylic resin was altered by the soaked time in the tamarind turmeric herb. The development of roughness can be affected by some factors, including the presence of acids, especially citric acid, liquid absorption, pH, the breaking down of polymer bonds, the level of hydrogen ions, and improper packing methods.
