Targeting this protein -- the ORAI1 calcium channel -- could provide a new approach to treating oral cancer, which causes persistent pain that worsens as it progresses.

A multi-disciplinary team of scientists led this effort. This is a critical first step to the long-term goal to develop stem cell-based treatments to repair damaged teeth and regenerate those that are lost. Enamel is made during tooth formation by specialized cells called amelobasts. These cells die off after tooth formation is complete. Consequently, the body has no way to repair or regenerate damaged enamel.

Now, new research shows a link between periodontal (gum) disease and the formation of amyloid plaque, a hallmark of Alzheimer's disease.

The study found that gum disease and tooth loss were linked to brain shrinkage in the hippocampus, which plays a role in memory and Alzheimer's disease. The study does not prove that gum disease or tooth loss causes Alzheimer's disease; it only shows an association.

Researchers developed a novel approach that promoted bone regeneration in mice without implantation of bone tissue or biomaterials.

A single dose of either topical treatment given in elementary schools prevented roughly 80% of cavities and kept 50% of cavities from worsening when children were seen two years later.

Now, researchers have found that it could be connected to even more severe problems elsewhere in the body -- the heart. In a new study, the research team found a significant correlation between periodontitis and atrial fibrosis in a sample of 76 patients with cardiac disease.

They found that patients who had heart attacks and received periodontal maintenance care had the shortest length of stay in the hospital, and more follow-up visits. The longest length of stay was experienced by the no-dental-care group.

Analysis of co-cultures of F. nucleatum with other commensal oral bacteria revealed that metabolic cross-feeding enables F. nucleatum to increase the production of the polyamines putrescine and cadaverine, thereby promoting the development of periodontitis. The nutritional interactions of F. nucleatum may serve as potential targets for the development of new methods to prevent periodontal disease.

New research unpacks the mechanism underlying this association, demonstrating in mice that a susceptibility to arthritis can be transmitted by a bone marrow transplant if the donor has gum inflammation.

The research team leveraged electronic dental and health records of 10,000+ patients to gain a better understanding of how oral health treatments affect individuals' overall health over time. The study found that people with dentures had a significant decline in nutrition markers. People who did not wear dentures did not experience this decline. This is believed to be the first study to report results of utilizing lab values of nutritional biomarkers and linking them with dental records.

The study, completed in an animal model and published in October in the Journal of Dental Research, found that excessive inflammation resulting from obesity raises the number of myeloid-derived suppressor cells (MDSC), a group of immune cells that increase during illness to regulate immune function. MDSCs, which originate in the bone marrow, develop into a range of different cell types, including osteoclasts (a cell that breaks down bone tissue).

It is the coordination between facial growth and the mechanics of the chewing muscles that determines not just where but when adult molars emerge. This results in molars coming in only when enough of a 'mechanically safe' space is created. Molars that emerge 'ahead of schedule' would do so in a space that, when chewed on, would disrupt the fine-tuned function of the entire chewing apparatus by causing damage to the jaw joint.
