Abstract: The invention concerns biomimetic peptides having a common pentapeptide sequence, which allow bone regeneration by activating the hydroxyapatite (Hap) deposition process. Their uses as a medicament, and specifically in the field of bone, dental (dentin and enamel) and periodontal regeneration, and in the functionalization of prostheses, screws, fixings, inserts or supports made of metal, ceramic, or natural or synthetic polymeric material are also described. Further described are a pharmaceutical composition and a cosmetic composition comprising such peptides, the use as a medicament, in bone, dental and periodontal regeneration, its cosmetic use and its use in the functionalization of prostheses, screws, fixings, inserts or supports made of metal, ceramic, or natural or synthetic polymeric material are further described.
