Is Hydrogel an Appropriate Bioadhesive Material for Sutureless Oral Wound Closure?

An effective surgical adhesive must possess strength, biodegradability, flexibility, non-toxicity, and the ability to accommodate to tissue movement. However, existing adhesives in the market lack some of these crucial properties. Both synthetic cyanoacrylate and natural fibrin glue have been explored for sutureless oral surgery, but they come with specific limitations. This perspective review aims to explore the novel potential of hydrogels as bioadhesives for wound closure in the oral cavity.
