Abstract
Background: Date Palm Seed Oil (DPSO) contains antifungal properties and health benefits due to the presence of essential minerals, nutrients, and antioxidants. Consequently, it has the ability to provide distinct characteristics when combined with Soft Denture Liner Material (SDLM); however, it may have an impact on the latter's physical and mechanical properties. Thus, the current study aimed to show how DPSO [Saudi (SA) or Pakistani (PK)] integration affects the roughness, hardness, wettability (contact angle), and thermal conductivity of SDLM. Materials and Methods: Two hundred SDLM specimens were manufactured and separated into five groups with varied (vol. %) DPSO concentrations depending on each test (n=40) for roughness, hardness, wettability, and thermal conductivity. The SDLM specimens were separated into five categories: Group A (0% pure control) with no DPSO integration, Group B 2.5%, Group C 5% (DPSO) [Saudi (SA)], Group D 2.5%, and Group E 5% (DPSO) [Pakistani (PK)]. All the synthesized samples were analyzed using Scanning Electron Microscope (SEM). The ANOVA test was employed to demonstrate considerable variance among all of the sample data. Results: Findings indicated substantial differences (P ≤ 0.05) in roughness, hardness, and thermal conductivity testing. There was a significant difference in wettability test results (P < 0.001) across all samples studied. Conclusions: Incorporating DPSO improved SDLM's roughness, hardness, wettability, and thermal conductivity, resulting in more distinctive SDLM. The 5% (DPSO) [SA or PK] produced an optimal proportion that enhanced the SDLM characteristics.
