Abstract

Objective: Dentures are the most common remedy for edentulous human population. Natural products and essential oils provide promising therapeutic agents for the treatment of oral infections. The increasing understanding of the diverse applications of natural resources has made them a favored substitute for manufactured materials. therefore, the goal of this study was to find out how different immersion solutions [thyme oil, Polident denture clean] changed the roughness, hardness, and transverse strength of 3D-printed PMMA denture base. Materials and Methods: The current study produced ninety 3D-printed resin samples, each measuring [65mm ×10mm×2.5mm] and classified them into three groups including 30 samples, each group were submerged into three groups depending on immersion solutions [control, thyme essential oil, and Polident denture cleaner] for a duration of 15 days. After that the samples were tested for surface roughness, hardness, and transverse strength. Results: The Polident immersion group had the highest surface roughness values followed by thyme essential oil, whereas the control group was demonstrated the lowest mean values. Likewise, the surface hardness test findings demonstrated that the Polident immersion group exhibited the greatest mean values, while the thyme immersion group had the lowest mean values but statistically was not significant. Furthermore, the transverse strength test indicated the lowest average transverse strength for the thyme essential oil group. Conclusion: Thyme essential oil as a denture cleaner better preserves surface roughness but has a lesser influence on the hardness and transverse strength of the 3D Print denture base compared to Polident denture cleanser.
