Hydroxyapatite (HAp) derived from rooster eggshells is rising as a “promising biomaterial in dentistry,” in accordance with a latest evaluate revealed in Proof-Primarily based Dentistry.
The evaluate, which analyzed 17 research on eggshell-derived hydroxyapatite (E-HAp), discovered the fabric provides “a variety of purposes” in tissue engineering and regenerative dentistry. The authors carried out a complete literature search within the PubMed and Scopus databases, in addition to a gray literature search.
Most research included within the evaluate had been in vitro investigations, specializing in makes use of comparable to sealing dentinal tubules and remineralizing early enamel caries lesions. E-HAp was additionally studied for tissue engineering functions, together with alveolar ridge preservation utilizing bone grafts and periodontal regeneration. Different potential purposes included regenerative endodontics and use as a pulp capping agent.

Rising curiosity in tissue engineering
The evaluate was prompted by rising curiosity in E-HAp for regenerative medication and tissue engineering, the authors famous.
Whereas the usage of hydroxyapatite — a naturally occurring calcium phosphate that’s the major inorganic part of bones and tooth — in human implants shouldn’t be new, researchers proceed to discover new sources for the fabric. Along with rooster eggshells, hydroxyapatite has been synthesized from bovine, pig, and fish bones; seashells; mussel shells; and sure crops. One 2018 examine even examined rooster beaks, a waste materials that may contribute to environmental considerations, as a possible supply.
Bioengineering can also be drawing inspiration from animals in broader regenerative dental analysis. In 2024, a crew at Tufts College in Massachusetts reported efficiently bioengineering human-like tooth in pigs, representing a big advance in dental regenerative medication.
