| Summary: | This study presents a novel approach to enhancing the longevity and efficacy of dental materials through the incorporation of Tung oil into polyurea microcapsule coatings. Tung oil is renowned for its superior moisture barrier and antimicrobial properties, and when merged with the durable nature of polyurea, it creates a coating poised to substantially improve self-healing capabilities in dental applications. Focusing on the dual objectives of mechanical fortitude and biocompatibility, this research meticulously evaluates the coatings' proficiency in withstanding the rigors of the oral environment and their compatibility with oral tissues. Employing a suite of bioassays, we meticulously assess the toxicity and antibiofilm characteristics of these coatings, in addition to their self-healing efficiency. These evaluations measure the coatings’ ability to autonomously repair physical damage and counteract microbial colonization. The results reveal that tung oil significantly enhances the polyurea matrix's intrinsic self-repair features, which proves crucial in resisting the abrasive and microbial challenges prevalent in the oral cavity. The modified coatings demonstrate marked improvements in wear resistance and microbial interaction, heralding a significant advancement in dental material technology. This in-depth analysis corroborates the amplified capabilities of Tung oil-infused polyurea coatings and paves the way for future investigations into the integration of natural oils within medical-grade material design, opening a new chapter in the synthesis of biomaterials tailored for oral healthcare advancements.
