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.

Benefits of charcoal-based dentifrices for oral hygiene still unproven

The growing visibility of charcoal and charcoal-based dentifrices, including many that are offered for sale on the Internet, raises questions about the re-emerging practice of brushing teeth with products containing charcoal.

Researchers compare effectiveness of natural and synthetic materials for dental pulp tissue engineering

To regenerate dental pulp tissue after emptying of a tooth's root canals researchers compared the effectiveness of 3D scaffolds made of natural or customized synthetic materials containing pulpal stem cells and dentin-derived growth factors.

Texas A&M expert explains reasons for having sensitive teeth

An ice cream cone on a hot July day can be a tasty way to beat the heat, but if you're one of the millions of people who have sensitive teeth, then that cold treat can be a real pain.

Researchers use 3D printing-inspired process to create new blood vessels in teeth

While root canals are effective in saving a tooth that has become infected or decayed, this age-old procedure may cause teeth to become brittle and susceptible to fracture over time. Now researchers at OHSU in Portland, Oregon, have developed a process by which they can engineer new blood vessels in teeth, creating better long-term outcomes for patients and clinicians.

Natural compound in grape seed extract could increase strength, life of composite-resin fillings

A natural compound found in grape seed extract could be used to strengthen dentin -- the tissue beneath a tooth's enamel -- and increase the life of resin fillings, according to new research at the University of Illinois at Chicago College of Dentistry.

Novel approach can regenerate dental pulp-like tissues in animal model

When a tooth is damaged, either by severe decay or trauma, the living tissues that comprise the sensitive inner dental pulp become exposed and vulnerable to harmful bacteria.

Anthropologists find new record of vitamin D deficiency in people who lived hundreds of years ago

Researchers at McMaster University have found a rich new record of vitamin D deficiency, one that resides in the teeth of every person and remains viable for hundreds of years or more.

New computed tomography method provides internal view of human tooth

Both in materials science and in biomedical research it is important to be able to view minute nanostructures, for example in carbon-fiber materials and bones. A team from the Technical University of Munich, the University of Lund, Charité hospital in Berlin and the Paul Scherrer Institute have now developed a new computed tomography method based on the scattering, rather than on the absorption, of X-rays.

UAB Research Probes Molecular Basis Of Rare Genetic Disorder

An international group co-led by University of Alabama at Birmingham researcher Mary MacDougall, Ph.D., has unraveled the molecular basis for the rare, inherited genetic disorder, Singleton-Merten Syndrome (SMS). Individuals with SMS develop extreme, life-threatening calcification of the aorta and heart valves, early-onset periodontitis and root resorption of the teeth, decreases in bone density, and loss of bone tissue at the tips of fingers and toes.

Noninvasive laser therapy triggers stem cells to repair enamel of teeth

A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine.

New bioinspired gel material could help repair damaged teeth and bone

A bit of pressure from a new shrinking, sponge-like gel is all it takes to turn transplanted unspecialized cells into cells that lay down minerals and begin to form teeth.

Almost 50% percent of population suffers from tooth sensitivity

Almost 50% percent of the population suffers from tooth sensitivity to cold, sweet and hot foods and liquids, according to a nationwide survey of 1,056 adults age 18—65+. Almost half of respondents had tried sensitivity toothpastes, but only about one-third of those found their experience to be positive, noted Larry Fishman, president of Majestic Drug Co., Inc.

Scientists report loss of dental material may be linked to reduction of tooth wear

Scientists of the Max Planck Institute for Evolutionary Anthropology in Leipzig and the Senckenberg Research Institute in Frankfurt together with dental technicians have digitally analysed modern human teeth using an engineering approach, finite element method, to evaluate the biomechanical behaviour of teeth under realistic loading.
