  Introduction: Heat-polymerized acrylic resin is used to manufacture almost all denture bases. One of the disadvantages of acrylic resin is its porosity and surface roughness; food scraps attach easily. If the dentures are not cleaned, they become a place for microbial species development and cause denture stomatitis, with Staphylococcus aureus and Candida albicans as the major etiologic agents. Adding nanoparticles of titanium dioxide to heat-polymerized acrylic resin may provide antimicrobial activity to the acrylic resin base.   Objectives: This study aimed to determine whether adding TiO2 nanoparticles to heat-polymerized acrylic resin denture base materials affected the amounts of Staphylococcus aureus and Candida albicans.   Methods: The samples in this study used heat-polymerized acrylic resin without the addition of TiO2 nanoparticles and with the addition of 2%, 3%, and 4% TiO2 nanoparticles on test bar sizes of 10 mm × 10 mm × 1 mm. There were 48 total test samples: 24 of Staphylococcus aureus and 24 of Candida albicans. The obtained data were analyzed by a one-way ANOVA test.   Results: The results showed that adding TiO2 nanoparticles influenced the amount of Staphylococcus aureus (p<0.05) and Candida albicans (p<0.05). A least significant difference test showed differences of effect in the amounts of Staphylococcus aureus when TiO2 concentrations of 2%, 3%, and 4% were added to heat-polymerized acrylic resin denture base and there were differences in effect to amounts of Candida albicans when TiO2 concentrations of 2%, 3%, and 4% were added to heat-polymerized acrylic resin denture base.   Conclusion: Adding TiO2 nanoparticles to heat-polymerized acrylic resin denture base material affects the amounts of Staphylococcus aureus and Candida albicans.

Denture Base

Denture base material should have a good level of biocompatibility. Acrylic resin is frequently used as a denture base material, however it has a disadvantage of producing residual monomer. Residual monomer is known to have a cytotoxicity effect. Titanium dioxide (TiO2) nanoparticles are used as fillers due to their biocompatibility and ability to enhance the mechanical properties of acrylic resin. The addition of the material to acrylic resin could affect the amount of residual monomer. The aim of this study was to examine the effect of the addition of TiO2 nanoparticles as acrylic resin denture base filler on the cytotoxicity in fibroblast cells. The samples consisted of 24 heat cured acrylic resins in disc shape (5 mm in diameter and 2 mm in thickness), divided into 4 groups (n = 6): three groups given treatment with0.5%, 1%, 2% TiO2, respectively and one control group. Cell viability was measured with MTT assay. The results were tested with one way ANOVA with 95% confidence level followed by LSD post hoc test. The results showed that the highest percentage of cell viability was found in the treatment group of 0.5% TiO2 with value of 91.83 ± 1.75%, while the lowest value was seen in the treatment group of 2% TiO2 with value of 79.38 ± 3.34%. Significant differences were shown between the treatment groups of 0.5% and 2% TiO2, as well as between the control and treatment group with 2% TiO2. The conclusions of this research are the addition of TiO2 nanoparticles as acrylic resin denture base filler has an effect on cytotoxicity; the addition of 0.5% TiO2 nanoparticles filler results in lower cytotoxicity on fibroblast cells compared to the addition of 1% and 2% TiO2.

Introduction: The denture base is the part of the removable denture that is supported by good adaptation to the underlying oral tissue. Most of the denture bases are made of acrylic or polymethyl methacrylate resin, better known as PMMA. However, the acrylic resin also has disadvantages such as easily broken and absorbs liquids both water and chemicals. The chemical absorption like alcohol, ethanol, and some drinks that contain acidic materials will chemically be induced with acrylic resin and settle in the pores of the acrylic resin. The chemical damage or defect creates roughness on the surface of the acrylic resin which can cause cracking or crazing and a decrease in surface strength and hardness. Materials and Methods: The method used in this research was a laboratory experimental design with a post-test-only control group using 12 samples consisting of 2 different types of samples by measuring the surface roughness of the acrylic resin after immersing the sample with a predetermined time. Results and Discussions: One-way ANOVA test results showed a significant difference in surface roughness after the samples immersion with a value of p = 0.006 (p <0.05). Conclusions: Based on this research, can be concluded that there is an increase in the surface roughness of the heated polymerized acrylic resin for 3 hours and 4 hours of immersion. The longer the heated polymerized acrylic resin is soaked in arak hence the level of surface roughness increases.
