Physicians and scientists agree: If we cannot entirely prevent cancer, the next best thing is to find it earlier to augment the chances of a successful [...]
Genetic Study Reveals The Origins Of Cavity-causing Bacteria
Researchers have uncovered the complete genetic make-up of the cavity-causing bacterium Bifidobacterium dentium Bd1, revealing the genetic adaptations that allow this microorganism to live and cause decay in the human oral cavity. The study, led by Marco Ventura’s Probiogenomics laboratory at the University of Parma, and Prof. Douwe van Sinderen and Dr Paul O’Toole of [...]
Over 90% with Gum Disease at Risk for Diabetes
An overwhelming majority of people who have periodontal gum disease are also at high risk for diabetes and should be screened for diabetes, a New York University nursing-dental research team has found. The researchers also determined that half of those at risk had seen a dentist in the previous year, concluded that dentists should consider [...]
Scientists Report New Resin Matrix Passes Initial Tests
Scientists report in this month’s issue of the journal Dental Materials that two synthetic molecules designed in their laboratory to improve the durability of composite fillings had acceptable strength and good biocompatibity during initial tests.
According to the scientists, these results suggest the structure of these so-called oxirane, or epoxy, molecules can be further refined in [...]
Researchers Identify Protein Involved in Causing Gum Disease, Osteoporosis, Arthritis
Investigators at Hospital for Special Surgery, collaborating with researchers from other institutions, have contributed to the discovery that a gene called interferon regulator factor-8 IRF-8 is involved in the development of diseases such as periodontitis gum disease, rheumatoid arthritis and osteoporosis. The study, which will be published online August 30, ahead of print, in the [...]
Mysterious strength of tooth enamel
It’s been a mystery: how can our teeth withstand such an enormous amount of pressure, over many years, when tooth enamel is only about as strong as glass? A new study by Prof. Herzl Chai of Tel Aviv University’s School of Mechanical Engineering and his colleagues at the National Institute of Standards and Technology and [...]
Nanotechnology may increase longevity of dental fillings
Tooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade. A Medical College of Georgia researcher hopes a new nanotechnology technique will extend the fillings’ longevity.

Antimicrobial properties of dentine bonding agents determined using in vitro and ex vivo methods
A guide to the potential antimicrobial activity of a DBA may be gained from an assessment of its pH when added to bacteriological culture medium. The direct contact method gives a better reflection of the killing of bacteria in infected dentine than the disk diffusion method. Killing in the ex vivo model gives a more [...]
