UF Researchers Map Bacterial Proteins That Cause Tooth Loss

The human mouth teems with millions of enamel-eroding, gum-inflaming microbes. Now scientists have...

Gene therapy promising for growing tooth-supporting bone

A University of Michigan research team has found that introducing a growth factor protein into a mouth wound using gene therapy helped generate bone around dental implants, according to a new paper in the February issue of the journal Molecular Therapy. In a patient with a sizeable mouth wound, replacing a tooth takes more than simply implanting a new one---the patient also needs the bone...

Mechanism regulating tooth shape formulation found

One of the remaining challenges for evolutionary developmental studies of mammals, whose evolution is best known from their teeth, is how their tooth shape is altered during development. Researchers of the University of Helsinki together with their Japanese colleagues from the University of Kioto now propose a 'balance of induction' mechanism directing the placement of tooth shape features called...

New tooth enamel dating technique could help identify disaster victims

Remnants of above-ground nuclear testing provide a way to determine age at time of death The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and 1960s is providing forensic scientists with a more precise way to determine a person's age at the time of death. The method could help in the identification of victims of Hurricane Katrina and other large-scale disast...

DNA traces evolution of extinct sabertooths and the American cheetah-like cat

By performing sequence analysis of ancient DNA, a team of researchers has obtained data that help clarify our view of the evolutionary relationships shared by the large predatory cats that once roamed the prehistoric New World. The work is reported in the August 9 issue of Current Biology by Ross Barnett of the University of Oxford and a team of researchers from Britain, the United States,...

Characterization of tooth decay

Quick and quantitative analytical evaluation of tooth decay is required in any study of the environmental factors promoting such decay. This information is essential to any study of which dental products are most effective in slowing or arresting the decay. <P>Teeth are naturally fluorescent solids, and are highly-scattering...

Not all tooth pain may have dental origins!!

The 58th annual session of the American Association of Endodontists in New Orleans, Louisiana, began with a warning from the scientific community. In a terse message, the dentists said that all toothache need not have dental origins and that toothache should not be ignored because it may be the early warning for more important problems. Especially in the third world countries, dental care and hyg...

New Tooth Paste Is Here To Fill In Dental Cavities

A Japanese team had invented a synthetic paste that will make dental treatment painless. The paste is made of modified hydroxyapatite // that is almost similar to natural tooth enamel, and can be applied on dental cavities to fill in the gap. Conventionally, when dental caries affects a tooth, the affected part is removed and the gap is filled with a metal alloy or resin. At times such...

Is caries in primary and permanent tooth related?

According to a study in Journal of Dental Research, caries in primary teeth may cause developmental defects in permanent teeth.// A primary tooth can have caries for a wide variety of reasons such as gender, family health or history, socio-economic status, years of exposure to water fluoridation, disturbance to primary teeth, and early loss of primary teeth. Accounting for all these dif...

Researchers developed world’s smallest toothbrus

Researchers of Rensselaer Polytechnic Institute have developed nano size toothbrush for //brushing your teeth. The toothbrush is made out of millions of cardbon nono tubes that are 30 times stronger than stel and five times less dense. The tooth brush bristles are usually made of animal hairs, polymer fibres and metal wires. Thesehave problems of corroding, wekening and melting. But th...

Post-Menopausal Status May Cause Tooth Decay

Researchers from the University of Buffalo, has found that Post-menopausal// women has an increased chance of loosing their tooth. The study was reported in the Journal of Periodontology, which was conducted in 106 Post-menopausal women during a follow up of 11.7 years. The results showed 57.5% of the women in the study lost at least one tooth. Alveolar bone loss may be cause of tooth loss in Pos...
