Researchers discover new way to predict caries development

A team of researchers form Russia discovered that an increase in the concentration of several substances in oral fluid can serve as the indication of caries development.

New biogenic dental product uses proteins to rebuild teeth, treat cavities

Researchers at the University of Washington have designed a convenient and natural product that uses proteins to rebuild tooth enamel and treat dental cavities.

Toothpastes alone cannot protect against dental erosion and hypersensitivity

The rising prevalence of dental erosion and dentin hypersensitivity has led to the emergence of more and more toothpastes on the market that claim to treat these problems. While no such toothpaste existed 20 years ago, today, many brands with different attributes are being offered.

Evidence-based approach to preventing or treating caries could transform dental care

A scientifically based approach that includes a tooth-decay risk assessment, aggressive preventive measures and conservative restorations can dramatically reduce decay in community dental practices, according to a study by researchers at UC San Francisco.

Penn study: New dental material kills bacteria and resists biofilm growth

Dentists rely on composite materials to perform restorative procedures, such as filling cavities. Yet these materials, like tooth enamel, can be vulnerable to the growth of plaque, the sticky biofilm that leads to tooth decay.

New device holds potential for early detection of cavities

Imagine if dentists could find clear signs of tooth decay long before dental lesions turn into cavities and without using X-rays. A new device cleared for commercialization this month by the Food and Drug Administration (FDA) is a potential tool for dentists to do just that.

UAB researchers create small molecule that prevents tooth cavities in preclinical model

University of Alabama at Birmingham researchers have created a small molecule that prevents or impedes tooth cavities in a preclinical model.

LSUHealthNO receives NIH grant to develop novel long-lasting dental filling materials

The National Institute of Dental and Craniofacial Research of the National Institutes of Health has awarded LSU Health New Orleans' School of Dentistry an R01 grant in the amount of $2,465,297 over five years to develop stronger, longer-lasting dental filling materials with antibacterial properties to inhibit recurrent cavities and extend the life of the restoration.

Mutated genes lead to tooth enamel defects that increase risk of caries

Bacteria are not the sole cause of caries; tooth resistance also plays an instrumental role. Researchers from the University of Zurich demonstrate that mutated genes lead to defects in the tooth enamel and can therefore encourage the development of caries.

New method allows early detection of tooth decay using long-wavelength infrared imaging

Dental caries-- tooth decay -- is the most prevalent dental disease among children and adults around the world. Left too long before treatment, the disease results in difficulty eating, infection, and even tooth loss.

Tips to help older adults maintain lifelong oral health

Seventy million people in this country - 20 percent of the US population -- will be 65 or older by 2030. If you're one of them, you probably think often about how to stay as fit and healthy as possible. But, you may not be giving as much thought to the health of your teeth.

Penn researchers use iron-containing nanoparticles to reduce plaque and prevent tooth decay

The bacteria that live in dental plaque and contribute to tooth decay often resist traditional antimicrobial treatment, as they can "hide" within a sticky biofilm matrix, a glue-like polymer scaffold.

New BioMinF toothpaste ingredient helps prevent decay and treat sensitivity

A new toothpaste ingredient which puts back the lost minerals from tooth enamel and helps prevent decay and treat sensitivity while you sleep is available online and from specialist dental distributors now. It is expected to be available through high street stores by the end of the year.

USC discoveries propose promising method to eliminate pain associated with tooth decay

Dual discoveries at USC propose a promising method to regrow nonliving hard tissue, lessening or even eliminating pain associated with tooth decay, which the National Institutes of Health calls the most prevalent chronic disease.

Ad Council survey: Many parents concerned about their children's teeth during Halloween

The largest candy-consumption night of the year is right around the corner. More than 80 percent of parents say their kids will participate in a Halloween celebration, and when asked about concerns related to Halloween, more than two-thirds of parents say they are worried about their children's teeth, according to a recent Ad Council survey.

Mutations in hair keratins increase risk for dental defects, caries

Today at the 93rd General Session and Exhibition of the International Association for Dental Research, researcher Olivier Duverger, National Institutes of Health-National Institute of Neurological Disorders and Stroke, Bethesda, Md., USA, will present a study titled "Hair Keratins as Structural Organic Components of Mature Enamel: The Link Between Hair Disorders and Susceptibility to Dental Caries."

BPA exposure may cause tooth enamel abnormality in children

A tooth enamel abnormality in children, molar incisor hypomineralization (MIH), may result from exposure to the industrial chemical bisphenol A (BPA), authors of a new study conclude after finding similar damage to the dental enamel of rats that received BPA.

Salivary mucins protect teeth from cariogenic bacterium

Salivary mucins, key components of mucus, actively protect the teeth from the cariogenic bacterium, Streptococcus mutans, according to research published ahead of print in Applied and Environmental Microbiology. The research suggests that bolstering native defenses might be a better way to fight dental caries than relying on exogenous materials, such as sealants and fluoride treatment, says first author Erica Shapiro Frenkel, of Harvard University, Cambridge, MA.
