Abstract:

Oral wounds caused by injuries, surgeries, diseases, and chemical irritations bring pain to the patient and increase the risk of infection. Effective wound protection and repair are crucial for improving patients’ quality of life and maintaining oral health. Wound dressings provide ideal healing conditions by isolating the wound from the oral environment. However, in the highly moist, microbiologically rich environment of the oral cavity, maintaining the stability of wound dressings remains a considerable challenge. Hydrogels show promising prospects for oral applications and are gradually becoming a research hotspot for addressing the challenges of oral wound protection and repair due to their excellent biocompatibility and versatile performance. In this paper, the current design strategies of hydrogel wound dressings that overcome the unique oral environment, achieve sustained adhesion and fulfill their functions are reviewed to provide new insights for the design of ideal oral wound barrier materials.

Key words: oral wounds, hydrogel dressing, wet adhesion, mechanical properties, controlled drug release systems
