“…This is in agreement with a study of [16], revealing that adding Thyme and Nigella oils to acrylic resin makes the material stronger across its width. These results are different from those of [17], who found in their study that adding eucalyptus, meramia, and ginger oils to acrylic resin made it weaker in the transverse direction. This could be because of differences in the type of oil and its chemical makeup, or because different amounts of oils were added to the material.…”

The objective of this study is to investigate the effects of radish oil on the transverse strength and surface roughness of polymethyl methacrylate. In this study, a total of sixty (60) samples have been made. 20 specimens of heatcured acrylic resin were created with no additives (control), and 40 samples were created with additives in different concentrations (2.5% wt and 5% wt) to test the surface roughness and the transverse strength. In the surface roughness test, a non-significant difference was found between the control and addition groups, but a high significant difference was observed in the transverse strength. When oils were added, the surface roughness decreased and the transverse strength increased. When radish oils were added to acrylic resin, the surface roughness decreased and the transverse strength increased.

“…This result agrees with Shukur [14], where the hardness decreased after adding tea tree oil to an acrylic resin. However, our findings contradict Al-Nema et al [12], possibly due to the type of oil used or the variation in oil concentration, causing oil to coat the polymer particles and reduce the conversion of monomer to polymer, resulting in a substantial quantity of leftover monomer.…”

“…The test group's flexural strength slightly decreased compared to the control group (Figure 2); however, an insignificant difference was found when assessed at different time intervals. This result contradicts Al-Nema et al [12], where adding eucalyptus, maramia, and ginger oils to an acrylic resin decreased flexural strength. In another study by Hatim et…”

Denture-induced stomatitis is a common condition that occurs beneath a denture due to unhygienic dental practices. Bergamot oil is extracted from a lemon hybrid and is a natural antifungal agent. This study incorporated bergamot oil into a PMMA resin matrix to evaluate its physicomechanical effects on the matrix. Results showed that bergamot oil had no adverse effect on the matrix: there were insignificant flexural strength and hardness changes. Also, the color of the matrix remained unchanged for four weeks! Our results prove that incorporating bergamot oil in a PMMA resin matrix can be an effective antifungal agent to prevent denture-induced stomatitis without causing any depreciation in the quality and shelf-life of the denture.

“…The increase in sample flexibility, especially at concentrations of 5%, which results in a decrease in hardness, is another potential explanation for this decline. Al-Nema research's findings don't match up with these findings, which might be a consequence of the essential oil used in the study or the different oil concentrations used [20].…”

Background: Heat-cured acrylic resins are used most often for denture bases because they are the best in terms of their physical and chemical properties, are easy to handle, and are affordable. But the surface is not hard enough, and oral bacteria such as Candida albicans stick to the resin. Objective: To assess how Radish oil affected heat-cured acrylic's impact strength and hardness. Patients and Methods: The intention was to create a total of (60) specimens. Twenty samples were made without additives (Control), and 40 had made with radish oil added at two different amounts (2.5 per cent, 5 per cent). Results: There was a Non-significant difference between the control and experimental groups in the impact strength test. In contrast, the hardness test showed a highly significant difference between the control and experimental groups. When radish oil had added, the impact strength and hardness had reduced in all concentrations. Conclusion: Adding radish oil decreased the hardness and impact strength of the two experimental groups.
