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 found. Its work provides new evidence of the impact that events, such as reproduction and imprisonment, have on an organism.
Nearly all older Americans support adding a dental benefit to the Medicare program that covers most people over age 65, according to a new national poll that also reveals how often costs get in the way of oral health for older adults.
The first study looking at the effect of chlorhexidine mouthwash on the entire oral microbiome has found its use significantly increases the abundance of lactate-producing bacteria that lower saliva pH, and may increase the risk of tooth damage.
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumor innervation could thus lead to new cancer therapies.
Biofilms are composed of bacteria living in a densely packed and organized community. Research from Amauri J. Paula, Geelsu Hwang, and Hyun (Michel) Koo of the University of Pennsylvania School of Dental Medicine paired high-level imaging tools with an algorithm to track a biofilm as it formed. Biofilm growth at multiple scales, they found, mimics aspects of how cities emerge from individual settlers.
Pain researchers around the world have agreed to classify pain in the mouth, jaw and face according to the same system. According to a participant from Aarhus University in Denmark, this means more precise diagnoses and improved treatment of people suffering from pain.
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 tooth to make new dentine. In a paper published today in the Journal of Dental Research, they have found further positive evidence that the method has the potential to be translated into a direct clinical approach.
Dental professionals could play a vital role in the diagnosis of Type 2 diabetes as well as identifying those at a high risk of developing the condition, new research by a team at the University of Birmingham's School of Dentistry has found.
The research assessed perceptions and experiences related to sexual, gender-based and nongender-based harassment among registrants at AADR annual meetings from 2015 to 2018 (n=10,495); examined demographic factors associated with reported experiences; and identified facilitators and potential solutions concerning these types of harassment. The survey received 824 responses, or 7.85%.
Most people know that good oral hygiene - brushing, flossing, and regular dental visits - is linked to good health. Colorado State University microbiome researchers offer fresh evidence to support that conventional wisdom, by taking a close look at invisible communities of microbes that live in every mouth. Their study found a correlation between people who did not visit the dentist regularly and increased presence of a pathogen that causes periodontal disease.
