Ancient Reptile Had Mammal-Like Tooth Enamel – “Strangest Teeth Ever Seen”
Priosphenodon specimens found in Argentina show the Late Cretaceous reptile evolved to have resilient tooth enamel similar to that in mammals. A new study by…
Every Tooth Tells a Different Story: Revealing Genetic Relationships in Humans
University of Tübingen researchers uncover dental traits revealing genetic relationships in humans, serving as proxy for DNA. Researchers at the University of Tübingen have shown…
Teeth Serve as ‘Archive of Life’ – Record Intimate Details of a Person’s Life
Teeth constitute a permanent and faithful biological archive of the entirety of the individual’s life, from tooth formation to death, a team of researchers has…
Teeth That Repair Themselves – Study Finds Success With Natural Tooth Repair Method
Over the last five years scientists at King’s College London have been investigating a method of stimulating natural tooth repair by activating cells in the…
Too Much Fluoride Causes Defects in Tooth Enamel – Researchers Found Out Why
Changes within enamel cells point to mechanism by which excessive fluoride leads to fluorosis. Exposing teeth to excessive fluoride alters calcium signaling, mitochondrial function, and…
Chewing Sugar-Free Gum Helps Reduce Tooth Decay in Adults and Children
A systematic review by King’s College London has found some evidence that chewing sugar-free gum could help to reduce the further development of dental caries…
‘Living Fossils’ – First Adult Molars Hold a Health Record Dating Back to the Womb
Researchers at McMaster University have found that a person’s first permanent molars carry a life-long record of health information dating back to the womb, storing…
Key New Molecules Uncovered That Could Help Tackle Tooth Loss and Regeneration
New research published in the Journal of Dental Research has shed light on the science behind the formation of the periodontal ligament. Our teeth take…
Biomechanics of Dental Features and Tooth Wear
A team of biologists examined the functional biomechanics of dental features and tooth wear, finding that the biomechanical requirements on teeth change during one’s lifetime….
Natural Dental Wear Protects Teeth Against Fatigue Failure
In a newly published study, researchers analyzed modern human teeth, finding that material loss protects teeth against fatigue failure. Scientists of the Max Planck Institute…
Researchers Grow Bioengineered Teeth
In a new study, scientists at King’s College were able to produce bioengineered teeth containing dentine, enamel and viable roots by using cells isolated from…
Jawless Vertebrate Conodont Had Sharpest Yet Minuscule Teeth
The conodont, an extinct primitive marine vertebrate, had the sharpest teeth ever known, with tips just one-twentieth of the width of a human hair, and…
