An observational study of 601 mother-child pairs from six cities in Canada hints at an apparent association between maternal exposure to fluoride during pregnancy and lower IQ scores measured in children ages 3 to 4. Community water has been fluoridated for decades to prevent tooth decay; a majority of US residents are supplied with fluoridated water, as are more than one-third of Canadian residents and about 3% of European residents.
A common origin shared by teeth and taste buds in a fish that has regenerative abilities has been identified by a team of researchers from the UK and the States.
Having one of the most powerful bites in the animal kingdom, crocodiles must be able to bite hard to eat their food such as turtles, wildebeest and other large prey. Now, researchers at the University of Missouri have found that crocodiles -- and even their plant-eating ancestors -- had thin tooth enamel, a trait that is in stark contrast to humans and other hard-biting species. These findings could suggest new approaches for dealing with people's teeth.
Stem cells hold the key for tissue engineering, as they develop into specialised cell types throughout the body including in teeth. An international team of researchers, including scientists from the Biotechnology Center of the TU Dresden (BIOTEC), has found a new mechanism that could offer a potential new solution to tooth repair.
This is a peer-reviewed, observational study conducted in mice. Stem cells hold the key to wound healing, as they develop into specialized cell types throughout the body -- including in teeth. Now an international team of researchers has found a mechanism that could offer a potential novel solution to tooth repair.
luoride exposure may lead to a reduction in kidney and liver function among adolescents, according to a study published by Mount Sinai researchers in Environment International in August.
Visits to the dentist drop significantly after adults turn 80, finds a new study by researchers at NYU Rory Meyers College of Nursing and the University of Hawai'i at Mānoa.
A special Lancet Series on Oral Health, published today in The Lancet, presents an 'urgent need for radical reform' of oral healthcare to prioritize prevention and integrate dentistry into primary care. The series is comprised of two papers, both co-authored by Habib Benzian, D.D.S., MScD.P.H., Ph.D., the associate director of global health and policy for NYU College of Dentistry's World Health Organization (WHO) Collaborating Center for Quality-improvement, Evidence-based Dentistry -- the only WHO Collaborating Center on oral health in the Americas.
Tooth decay, gum disease and oral cancers are a major health burden worldwide, but are largely ignored by the global health community, according to a series on oral health in The Lancet that publishes July 20, 2019. In a commentary accompanying the series, Cristin Kearns and Lisa Bero express growing concern that the dental profession will not make meaningful progress in combating the oral health epidemic until it addresses the sugar industry's influence on dental research.
Root canal work is not as bad as people think when compared to other dental procedures. Self-reporting of their dental health suggests that patients find the procedure no worse than other dental work which overturns the popular belief that root canal work is the most unpleasant dental treatment.
