The Purpose Of The Study: Was to assess the microbial colonization and biofilm-forming activity of conditionally pathogenic microorganisms in vitro to samples of acrylic-free thermoplastic polymer material and to assess the possibility of its use for the manufacture of removable tooth splinting structures by injection method.
Materials And Methods: The reference strains . Biofilm-forming activity was assessed by the level of ethanol extraction of a 0.1% aqueous solution of gentian violet by measuring on a PowerWave X microplate reader (USA).
Results: A low degree of severity of microbial colonization and sufficient colonization resistance to the formation of a microbial biofilm of (0.374±0.056 cu opt. Pl.), (0.272±0.039 cu. Opt. Pl.), (0.299±0.028 cu opt. Pl.), (0.399±0.069 cu opt. Pl.), (0.401±0.089 cu opt. Pl.). Moreover, strains form a more pronounced biofilm (0.425±0.104 cu opt. Pl.) in comparison with other strains studied in the experiment.
Conclusion: Samples from a thermoplastic polymer based on polyoxymethylene have satisfactory biomedical characteristics and can be used at the stages of dental orthopedic treatment of patients without oral candidiasis.

The fabrication of objects with complex shape and geometry has been greatly facilitated with the advancements in additive manufacturing. While synthetic polymers like ABS and PLA have found widespread use in extrusion 3D printing, other biobased thermoplastics that are both biodegradable and biocompatible could offer strategic advantages over traditional synthetic materials. In this work dextran of low (20 kDa) and medium (40 kDa) molecular weight (MW) was modified with palmitic acid to obtain meltable polymers for extrusion 3D printing/fused deposition modeling additive manufacturing.

The transition from insulator to electro-responsive has been successfully achieved by earlier studies for some inorganic materials by applying external stimuli that modify their 3D and/or electronic structures. In the case of insulating polymers, this transition is frequently accomplished by mixing them with other electroactive materials, even though a few physical treatments that induce suitable chemical modifications have also been reported. In this work, a smart approach based on the application of an electro-thermal reorientation process followed by a charged gas activation treatment has been developed for transforming insulating 3D printed polymers into electro-responsive materials.

Article Synopsis
- This study explores how incorporating cotton and polyester fibers into polypropylene (PP) composites can improve their mechanical, thermal, and rheological properties, aiming for durable materials.
- The research finds that a balanced mix of cotton and polyester fibers maximizes tensile strength and stiffness, with different coupling agents influencing fiber-matrix adhesion and overall performance.
- The use of recycled textile fibers not only bolsters thermal resistance and structural stability but also presents a sustainable solution that supports the circular economy by repurposing textile waste in composite manufacturing.
