Dental :: Dental crowns reveal the diet of a species

According to recent research, the complexity of tooth surfaces reveals the diet of a species. Scientists at the University of Helsinki’s Institute of Biotechnology and Department of Geology showed that the more complex the surface of an animal’s teeth, the greater the share of vegetables in its diet. For instance, the teeth of carnivores and rodents differ in almost every aspect, but if a carnivore and a rodent eat similar food, their teeth are equally complex. The results were published in Nature.

Dental Health :: Oral Medicine by Professor Crispian Scully

Oral Medicine, which Professor Scully co-wrote with Sergio Gandolfo and Marco Carozzo, both of the University of Turin, Italy, is designed to help dental practitioners recognise the signs and symptoms of conditions affecting the soft tissues of the mouth, such as ulcers and oral cancer, as well as the oral effects of systemic diseases. The title is published by Churchill Livingstone Elsevier.

Dental :: Fibers used in bullet-proof vests quadruple toughness of dental composites

Vistasp Karbhari, a professor of structural engineering at UC San Diego, has developed fiber-reinforced polymer composites as strong, lightweight materials for aerospace, automotive, civil and marine applications, so he thought, “If they work so well in highway bridges, why not dental bridges.”

Dental Health :: Study Finds Periodontal Treatment Does Not Lower Preterm Birth Risk

Scientists supported by the National Institute of Dental and Craniofacial Research, part of the National Institutes of Health, report in this week?s New England Journal of Medicine that pregnant women who received non-surgical treatment for their periodontal, or gum, disease did not also significantly lower their risk of delivering a premature or low-birthweight baby.

Dental Health :: Do not use a specific lot of Neutragel sodium fluoride gel due to mould contamination

This sodium fluoride gel is administered in a dental office or at home.

Dental Health :: Promising Approach to Prevent Tooth Decay

Preventing cavities could one day involve the dental equivalent of a military surgical strike. A team of researchers supported by the National Institute of Dental and Craniofacial Research report they have created a new smart anti-microbial treatment that can be chemically programmed in the laboratory to seek out and kill a specific cavity-causing species of bacteria, leaving the good bacteria untouched.

Dental Health :: Oragenics reports positive clinical results with its oral probiotic mouthrinse

Oragenics, Inc. (Amex: ONI) announced today that the first of two sets of subjects has completed a clinical trial utilizing its proprietary oral probiotic product, Probiora3(TM). The trial was designed to determine safety and the effectiveness of the mouthrinse against baseline levels of disease-causing bacteria in the mouth. Daily mouth rinsing with Probiora3(TM) resulted in substantial reductions in the numbers of the bacterium, S. mutans, which attacks teeth, as well as two target periodontal strains, Porphyromonas gingivalis and Campylobacter rectus, associated with gum disease and bad breath. The product was well tolerated by the subjects and no safety issues were identified with the twice daily use of the product over a two-month period.
