Miswak fiber particles and polymer (MFP/PEEK) influence incorporation on properties, biocompatibility of PMMA composites

Abstract

The PMMA (polymethyl methacrylate) composite is made using a particular percentage of polyether ketones (PEEK). In this study, 5% of PEEK is used, along with a chosen proportion of Miswak (MFP) natural fiber particles in two different particle sizes—coarse and fine, using a hand-layout technique. Using PSD the particle size dimension is a quantitative measure of the size of particles, typically expressed in terms of diameter, length, or other relevant dimensions, and is crucial in determining the physical and chemical properties of materials. of both kinds (31112.3 nm coarse and 816.3 nm fine) are assessed.  Every manufactured PMMA composite underwent a number of tests, including ones for density, water absorption, and biocompatibility. The findings indicated for the density test revealed a reduction when sample S6 (1.042 g/cm3) is supplemented with 8wt.% of fine MFP. For water absorption rate, the addition of fine MFP as in in sample S6 attaining a maximum value of 38.42, whereas S2 had the lowest water absorption value, and its value is (1) which is reinforced with PMMA/PEEK blends, Miswak fiber nanoparticles (MFP), which exhibit strong antibacterial and cytotoxic properties and could be used as a source for medication delivery in health enhancement, show promise as a healing agent when added to PMMA composites. At 28 mm, sample S6 8% weight percentage of fine MFP had the greatest lethal impact on E. coli cells. Together with testing investigations, these PMMA tests demonstrated the formulation's effectiveness and bacterial resistances, which made it a highly successful combination in dentistry. In contrast, PMMA biocompatibility testing produced superior results and demonstrated resistance to microbes.
