The development of biomaterials is not a new area of science, having existed for around half a century. The study of biomaterials is called biomaterial sciences. Biomaterial sciences encompass elements of medicine, biology, chemical/chemistry, tissue engineering and material sciences. Biomaterial sciences involve customization of materials for medical applications. Examples of these applications include artificial skin, vascular and cardiovascular implants and devices, bone graft substitutes, prosthetic devices, dental materials etc.
Recently, materials (biomaterial) used in medicine have made enormous impact on the repair and replacement of injured and diseased part of the human body and the field is growing at a rapid pace. While the implementation of some of the biomedical materials may be for medical reasons such as the replacement of diseased tissues required to extend life expectancies, other reasons may include purely artistic one including breast implants. This increasing demand arises from an ageing population with higher quality of life expectations. The biomaterial scientists are producing new and improved implantable materials and techniques to meet this demand.

Counterfeit Colgate Toothpaste Found in U.S. Could Contain Poison
Counterfeit tubes of Colgate brand toothpaste, possibly containing Diethylene Glycol, a poisonous chemical used in antifreeze, have been found in at least four states. The toothpaste was reportedly being sold from small dollar and discount stores in New York, New Jersey, Pennsylvania and Maryland.
These 5 oz. tubes of counterfeit toothpaste appear to be regular Colgate toothpaste, but a closer look at the label shows several misspellings along with the words, "Manufactured in South Africa." The Colgate Palmolive Company states that Diethylene Glycol is not used in any Colgate toothpaste in the United States or anywhere else in the world and Colgate does not import toothpaste from South Africa into America.
The Colgate Company is working closely with the United States Food and Drug Administration (FDA) and taking steps to ensure that none of their accounts have the counterfeit toothpaste on their shelves.

Blast of gas that could replace dentist's drill and make fillings stronger
A new ‘gas-firing’ device may offer a
pain-free alternative to the dentist’s drill — and could make fillings even more
hard-wearing.
The device, which resembles an electric toothbrush, cleans out cavities in rotten teeth in only 30 seconds, according to new research.
It works by generating high-energy gas and liquid particles to kill bacteria and blast out the decayed pulp of the tooth.

Fluoridated toothpaste fast falling out of favour
FLUORIDE is a naturally occurring element that prevents tooth decay when ingested systemically or applied topically. Researchers believe that there are several mechanisms by which fluoride achieves its anti-carious effect. It reduces the solubility of enamel in acid by converting hydroxyapatite into less soluble fluoroapatie; it may exert an influence directly on dental plaque, reducing the ability of plaque organisms to produce acid; and it promotes the remineralization of tooth enamel in areas that have been decalcified by acids.
Most likely, fluoride works by a combination of these effects. But the remineralization effect of fluoride is of prime importance, because it results in a reversal of the early caries process, and gives rise to enamel more resistant to decay.
In 1914, fluoride was added to toothpaste, but became more widespread when it was recommended by the American Dental Association (ADA) in the 1950s. The Centers for Disease Control and Prevention has proclaimed community water fluoridation as one of the 10 great public health achievements of the 20th Century. Most States in the USA have fluoride in their drinking water. However, relatively recently, there has been some reconsideration among the scientific community about this material.

Dentists Could Screen 20 Million Americans For Chronic Physical Illnesses
Nearly 20 million Americans annually visit a dentist but not a general
healthcare provider, according to an NYU study published in the American
Journal of Public Health.
The study, conducted by a nursing-dental research team at NYU, is the first of its kind to determine the proportion of Americans who are seen annually by a dentist but not by a general healthcare provider.
This finding suggests dentists can play a crucial role as health care practitioners in the front-line defense of identifying systemic disease which would otherwise go undetected in a significant portion of the population, say the researchers.

How Cavity-Causing Microbes Invade Heart
Scientists have discovered the tool that bacteria normally found in our mouths use to invade heart tissue, causing a dangerous and sometimes lethal infection of the heart known as endocarditis. The work raises the possibility of creating a screening tool -- perhaps a swab of the cheek, or a spit test -- to gauge a dental patient's vulnerability to the condition.
The identification of the protein that allows Streptococcus mutans to gain a foothold in heart tissue is reported in the June issue of Infection and Immunity by microbiologists at the University of Rochester Medical Center.
S. mutans is a bacterium best known for causing cavities. The bacteria reside in dental plaque -- an architecturally sophisticated goo composed of an elaborate molecular matrix created by S. mutans that allows the bacteria to inhabit and thrive in our oral cavity. There, they churn out acid that erodes our teeth.
The above story is reprinted from materials provided by University of Rochester Medical Center.

Teeth of Dead Bodies can Reveal Their Identity?
Researchers from the University of Granada have said that a person's dental patterns could be as reliable an identity proof for dead bodies as DNA.
Forensic police uses DNA testing to reveal the identity of dead bodies.
The researchers came to the conclusion after analysing the dental patterns of more than 3,000 people.
"There is sufficient dental diversity between people to enable a scientifically-based human identification method to be developed for forensic purposes," said Stella Martin de las Heras, lead author of the study.
