| Summary: | Purpose. Investigate the effect of long-term 90-time immersion in tea tree oil denture cleanser solution on the roughness, hardness, UV absorption, water sorption, and solubility of a heat-cured acrylic resin. Material and methods. An in vitro /laboratory study of one-hundred twenty specimens of heat cured acrylic resin were performed and divided into four sets. Each set consist of 30 specimens that distributed into three groups (group 1: distilled water, group 2: 0.75% tea tree oil and group 3: 1% tea tree oil), totaling with 10 specimens per group. The specimen were immersed for ten minutes in accordance to its groups 90 time to simulate six months. After periods of immersion the specimens were tested for surface roughness, hardness, UV-absorption, water sorption, and solubility. One-way analysis of variance ANOVA and Tukey HSD were used to assess the data at a significant level α=0.05. Results. Tea tree oil solutions had a statistically non-significant differences (P >0.05) on acrylic resin hardness property and UV-absorption test (P>0.05) and statistically significant effect of acrylic properties in surface roughness (P<0.05), with significant decrease in water sorption and solubility (P<0.05), after 90 time immersions. Conclusion. Immersion of heat cured acrylic resin specimens in tea tree oil result in statistically significant increase in the surface roughness, significant decrease in water sorption and solubility after immersion, while the hardness and UV-absorption properties had not affected. |
