Developing functional hydrogels for treatment of oral diseases.

Oral disease is a severe healthcare challenge that diminishes people's quality of life. Functional hydrogels with suitable biodegradability, biocompatibility, and tunable mechanical properties have attracted remarkable interest and have been developed for treating oral diseases. In this review, we present up-to-date research on hydrogels for the management of dental caries, endodontics, periapical periodontitis, and periodontitis, depending on the progression of dental diseases. The strategies of hydrogels for treating oral mucosal diseases and salivary gland diseases are then classified. After that, we focus on the application of hydrogels related to tumor therapy and tissue defects. Finally, the review prospects the restrictions and the perspectives on the utilization of hydrogels in oral disease treatment. We believe this review will promote the advancement of more amicable, functional and personalized approaches for oral diseases.
