Research Overview
P11-4
P11-4 has been studied for its ability to penetrate initial carious lesions and self-assemble into a fibrillar matrix that nucleates hydroxyapatite. Human and preclinical studies support its role in non-invasive enamel repair.
hBD-1
hBD-1 has been studied as part of the oral mucosal defense system and is linked to host resistance against dental pathogens. Research spans periodontitis, candidiasis, and epithelial barrier biology.
