Classification of Oral Ulcers and Its Treatment by Focusing on Exosome Loaded Hydrogel: A Comprehensive Review

Background: Oral ulcers significantly impact patient quality of life, manifesting as acute or chronic lesions that can cause considerable discomfort and pain. These ulcers arise from a variety of etiological factors and disrupt daily activities due to the painful loss of mucosal tissue. Objective: This review aims to elucidate the etiology and management of oral ulcers, with a focus on innovative treatment modalities involving hydrogels and exosomes. Methods: We reviewed current literature on the pathology and treatment of oral ulcers. Special attention was given to the properties of hydrogels and exosomes, their biomedical applications, and their roles in new therapeutic strategies for oral ulcers. Results: Hydrogels, due to their biocompatibility, biodegradation, and controlled release properties, have emerged as effective drug delivery systems. Exosomes, loaded within these hydrogels, enhance treatment outcomes due to their high cellular communication capacity and anti-inflammatory properties. Conclusion: Innovative treatments utilizing hydrogels and exosomes offer promising alternatives for the management of oral ulcers, potentially improving drug delivery efficiency and patient compliance.
