Evo-devo models of tooth development and the origin of hominoid molar diversity

Abstract The detailed anatomical features that characterize fossil hominin molars figure prominently in the reconstruction of their taxonomy, phylogeny, and paleobiology. Despite the prominence of molar form in human origins research, the underlying developmental mechanisms generating the diversity of tooth crown features remain poorly understood. A model of tooth morphogenesis—the patterning cascade model (PCM)—provides a […]

An Alzheimer’s drug might be able to repair cavities in teeth

A recent discovery about an Alzheimer’s drug may lead to the end of cavity fillings in teeth as we know them. Scientists discovered the drug, Tideglusib, promoted natural tooth regrowth during its clinical trials on mice, which led to total repair of cavities. They learned the drug stimulates stem cells in teeth, which creates new […]

Tooth Wear In Lake Titicaca Basin Foragers Signals Processing Of Wild Tubers Prior To Domestication

The central Andean highlands of Peru and Bolivia is one of only a few regions of the world where native plants and animals were independently domesticated in the ancient past. Evidence for dozens of domesticated species, including tubers, quinoa, llamas, and alpacas, began to emerge in the region some 5,000 years ago. The process of […]

A new technology for producing nano-hydroxyapatite developed by Lobachevsky University chemists

Today, deterioration of human health is one of the most pressing problems that modern medicine is facing. First of all, it concerns the widespread degradation of hard tissues – bones and teeth. To solve this problem, it is necessary to create medical materials capable of restoring the structure of hard tissues. The chemical basis of […]

Comparative evaluation of fracture resistance of primary anterior teeth restored with long dentine posts and teeth restored with short fiber posts: An in vitro study

Abstract Background Badly broken primary teeth that require pulp therapy present a high-risk of biomechanical failure due to the loss of tooth substance resulting from pre-existing decay and endodontic therapy itself. The introduction of Biological dentine posts offered an excellent alternative for restoring such teeth. The ideal post material should have physical and mechanical properties […]

Scientists Have Discovered a Drug That Fixes Cavities and Regrows Teeth

Dental fillings may soon be left in the ash heap of history, thanks to a recent discovery about a drug called Tideglusib. Developed for and trialled to treat Alzheimer’s disease, the drug also happens to promote the natural tooth regrowth mechanism, allowing the tooth to repair cavities. Tideglusib works by stimulating stem cells in the […]
