Research Overview
LRAP
LRAP is one of the better-known amelogenin-derived peptides in regenerative dentistry because it can influence mineralization-related cell behavior. It remains a research peptide, but it is highly relevant to enamel repair and tooth-tissue engineering.
Histatin-5
Histatin-5 is a major salivary defense peptide that can kill Candida species and influence oral microbial communities. It is also investigated for wound-healing and xerostomia-associated oral infection models.
