However, the major structural components making up hair and teeth are very distinct. The hair shaft is essentially made of keratin filaments that are highly cross-linked. Tooth enamel matrix is primarily composed of enamel proteins (amelogenin, ameloblastin) that are degraded and replaced by minerals during enamel maturation. Fully mineralized enamel contains a small fraction of cross-linked organic material that has not been fully characterized. In this study, researchers assessed the presence and functionality of a specific set of hair keratins in this organic fraction of enamel.
