A University of Florida researcher has developed a genetically altered bacteria strain, called an effector strain, that can permanently prevent tooth decay. The new strain, constructed from the naturally occurring bacterium Streptococcus mutans, breaks down food sugars and thrives on high-sugar diets.
A team of scientists has discovered the gene responsible for Papillon-Lefevre syndrome, a rare condition characterized by thick, cracked skin and premature tooth loss. The study identified mutations in the cathepsin C gene, which may help understand the development of periodontal disease.
The University of North Carolina at Chapel Hill is launching a unique project to reduce tooth decay among the state's youngest children by applying fluoride varnish on their teeth starting from 9 months. Despite improvements in dental health over the past three decades, 20-25% of young children still suffer from severe tooth decay.
Dinosaur tooth enamel holds secrets to ancient climate conditions, with new analysis suggesting middle latitudes may not have been warmer than today. Data from Madagascar indicates sub-tropical latitudes were warmer and more arid during the Late Cretaceous era.
UCSF researchers are using powerful microscopes to observe the bonding process between tooth enamel and dentin. By analyzing structures as small as two micrometers, they aim to develop methods for creating tighter, more permanent bonds between teeth and plastic-based fillings.
Researchers found a strong relationship between bone loss, gum disease, and tooth loss in postmenopausal women. The study suggests that women with osteoporosis may be at higher risk of developing periodontal disease.
The study found that fluoride protects smooth surfaces of teeth, while dental sealants fill pits and fissures to prevent decay. Sealants are recommended for children, adolescents, and adults who have experienced tooth decay in these areas.
Researchers estimate Tyrannosaurus Rex could exert a biting force of up to 3,011 pounds on its prey, with 58 definite T-rex bite marks found on a Triceratops pelvis. The powerful dinosaur's teeth were as strong as those of an alligator, suggesting it could have struggled with its prey.
