LONDON, England: Previous research has shown that, when combined, dental epithelial and mesenchymal cells can form tooth-like structures in vitro called organoids, which mimic the structure and development of teeth and can mature into functional organs. Researchers have explored various biomaterials in which to grow these, but many lack precise control over their properties. A recent study has introduced a new approach using customisable gelatine-based hydrogels, allowing better control of the material environment to investigate and support formation of tooth organoids. The study highlights the potential of bioengineered teeth as an alternative to dental restoration.
