The oral cavity is an open and complicated structure with a variety of factors affecting topical medications. physical chemical surroundings the can influence action free drugs. Thus, drug delivery system serve as support or carrier. Hydrogels are prospective tissue engineering biomaterials that demonstrate immense potential for regeneration delivery. crosslinked polymer chains 3-dimensional network take up larger volumes liquid have soft, porous closely resembles living tissue. protect active from systemic elimination, increase bioavailability absorption into cells, release modify therapeutic immediately after dosing. In this review, we introduce classification hydrogels, application hydrogels in diseases (periodontal disease, endodontics, mucosal alveolar surgery, cancer, maxillofacial bone defects, implantation), summarize synthesis methods applications discuss possible directions future development which will provide new idea formulation production more advantageous efficient system.

As a drug delivery system with vast potential applications, hydrogels have garnered significant attention due to their unique loading mechanisms and effectiveness. In this paper, novel reversible thermosensitive hydrogel polymer, synthesized through copolymerization of mono-6-allyl-β-cyclodextrin, N-isopropylacrylamide, acrylamide, is introduced. This polymer formed three-dimensional network structure in water, featuring β-cyclodextrin hydrophobic cavities. The encapsulated molecules could be slowly progressively released from both the IR XRD analysis confirmed successful encapsulation target molecules, sodium salicylate naproxen sodium, within cavity its space. Specifically, when mass ratio N-isopropylacrylamide/acrylamide/mono-6-allyl-β-cyclodextrin was 9.8/0.2/0.5, demonstrated an initial gelation temperature 34.9 °C final 37 °C. expansion rate blank slightly higher than that drug-loaded hydrogel. Both drugs undergo sustained release hydrogel, adhering Fick's diffusion law, ensuring consistent 8 h maintaining for over 24 h, regardless rate. Within 30 days, degradation PBS exceeded 15%, while presence lysozyme more 40%. These properties render versatile candidate targeted biomedical offering strategies treating chronic diseases other conditions.

Polysaccharide-based hydrogels have emerged as indispensable materials in tissue engineering and wound healing, offering a unique combination of biocompatibility, biodegradability, structural versatility. Indeed, their three-dimensional polymeric network high water content closely resemble the natural extracellular matrix, creating microenvironment for cell growth, differentiation, regeneration. Moreover, intrinsic tunable chemical structure, non-toxicity, minimal immunogenicity make them optimal candidates prolonged drug delivery systems. Notwithstanding numerous advantages, these polysaccharide-based are confronted with setbacks such variability material qualities depending on source, susceptibility to microbial contamination, unregulated absorption, inadequate mechanical strength, unpredictable degradation patterns which limit efficacy real-world applications. This review summarizes recent advancements application hydrogels, including cellulose, starch, pectin, zein, dextran, pullulan hyaluronic acid innovative solutions delivery, engineering, regenerative medicine. Future research should concentrate optimizing hydrogel formulations enhance effectiveness medicine antimicrobial therapy.
