Orodispersible film based on hyaluronic acid and morin for dental biofilm control.
Orodispersible films (ODFs) are an innovative oral drug delivery method benefiting pediatric, geriatric, and non-compliant patients. They are portable, easy to swallow, and enhance bioavailability. Hyaluronic acid (HA) stands out among hydrophilic polymers for oral delivery of antimicrobial agents. This study evaluated the physicochemical properties, in vitro release profile, and antimicrobial/antibiofilm activity of HA-based ODFs combined with the flavonoid morin, known for its antimicrobial properties. Antimicrobial activity and microbial viability were assessed via biomass quantification. The films were thin (12-27 µm), flexible, homogeneous, and mechanically resistant. A burst release of morin was observed, reaching complete release at 210 min. Cytotoxicity analysis confirmed the non-toxic profile, showing cell viability. HA-morin films significantly reduced Streptococcus mutans biofilm mass, viability, and acidogenicity compared to the controls. Findings confirmed the non-toxic, and their significant antibiofilm activity against S. mutans. This innovative mucoadhesive system has potential for managing dental diseases and oral drug delivery.
期刊介绍：
Biofouling is an international, peer-reviewed, multi-discliplinary journal which publishes original articles and mini-reviews and provides a forum for publication of pure and applied work on protein, microbial, fungal, plant and animal fouling and its control, as well as studies of all kinds on biofilms and bioadhesion.
Papers may be based on studies relating to characterisation, attachment, growth and control on any natural (living) or man-made surface in the freshwater, marine or aerial environments, including fouling, biofilms and bioadhesion in the medical, dental, and industrial context.
Specific areas of interest include antifouling technologies and coatings including transmission of invasive species, antimicrobial agents, biological interfaces, biomaterials, microbiologically influenced corrosion, membrane biofouling, food industry biofilms, biofilm based diseases and indwelling biomedical devices as substrata for fouling and biofilm growth, including papers based on clinically-relevant work using models that mimic the realistic environment in which they are intended to be used.
