Dental Health & Nutrition

Nutrition is at the top of the priority list for dental health. Research has discovered strong correlations between optimal oral health and great nutrition habits. This study shares the links uncovered and how families can implement them in their daily routines. Read more about nutrition and dental health...

More stress needs to be placed upon other aspects to truly determine one’s oral health. The practice paper “Oral Health and Nutrition” has been published on the Academy of Nutrition’s Web site, which backs up the Academy’s paper that appeared in the Journal of the Academy of Nutrition and Dietetics last year. Based on the information from the paper, nutrition assessment is one of the keys to pinpointing dietary intake and other nutritional factors that could impact a person’s oral health. It’s also important for dentists to stress the value of food choices to ensure that a person can maintain optimal oral health.

Can Dental Health Affect Mental Health?

The affects of Alzheimer's disease impacts the entire family and can drastically change the structure of a family's life. Could there be links between dental and mental health? This study by the University of Central Lancashire discovered that poor oral hygiene can  impose a higher risk for development of Alzheimer's. Those with healthy dental practices showed lower risks for development.

"Research currently under way at UCLan is playing an active role in exploring this link," Prof. St John Crean continues, "but it remains to be proven whether poor dental hygiene can lead to dementia in healthy people, which obviously could have significant implications for the population as a whole. It is also likely that these bacteria could make the existing disease condition worse." The researchers hope that continued donation of brain tissue will enable examination of more samples from people with and without Alzheimer's disease who have relevant dental records.

Dental Cavities May Lower Cancer Risk

Dental cavities may have an unexpected twist for good. A study by the University of Buffalo researchers have discovered a link between dental cavities that reduce the risk of head and neck cancer. The results are surprising and the researchers are trying to connect the links while addressing the consequences of both the dental cavities and cancer.

Dental cavities (or caries) are caused by tooth decay. This is when the bacteria present in the mouth make lactic acids that strip away minerals in the tooth by fermenting carbohydrates. According to the researchers from the University at Buffalo, NY, previous studies have shown the bacteria that causes tooth decay is linked to an immune response, which may be protective against cancer.

Protein vs. Periodontal Disorders

Researchers have discovered links between periodontal disorders and rheumatoid arthritis. These findings have also contributed to supporting evidence that protein has a strong impact on dental infections by oral pathogens. The early detection of periodontal disorders can be treated to offset future health problems. Learn more about the research to improve the treatment of periodontitis.

Periodontal, or gum, disease is one of the most common infectious diseases. In its more severe forms, such as periodontitis, it causes loss of the bone that supports the teeth. Approximately 65 million adults in the United States are affected by some form of the disease. PG is the major causative agent of periodontitis, and it may also be involved in the development of systemic diseases such as atherosclerosis and rheumatoid arthritis.

Scientists Discover a Better Way to Identify Dental Infections

Scientists at the University of Nottingham are developing new techniques to locate the source of infections. They plan to use these advancements for the improvement of dental care in developing countries. This new research could greatly reduce the potential for infections to develop. The research uses fluorescent markers to tag the cells. Read more about the use of metabolic machinery to combat dental infections.

The research was led by Professor Cameron Alexander, Head of the Division of Drug Delivery and Tissue Engineering and EPSRC Leadership Fellow in the University's School of Pharmacy, building on work by PhD student Peter Magennis. Professor Alexander said: "Essentially, we have hijacked some of the metabolic machinery which bacteria use to control their environment, and used it instead to grow polymers which bind strongly to the specific bacteria that produce them. "The neat thing about this is that the functionality of the polymers grown on the surface of the bacteria is programmed by the cells so that they can recognise their own 'kind'. We used fluorescent labels to light up the polymers and were able to capture this labeling using a mobile phone camera, so in principle it could be possible to use these materials as point-of-care diagnostics for pathogenic bacteria."

Research to Prevent Periodontal Disorders

The School of Dental Medicine's Department of Microbiology is collecting research to treat and prevent periodontal diseases. According to the American Academy of Periodontology, 47.2% of Americans over the age of 30 have periodontal disease. This article highlights the school's research findings and how it may benefit dental health in the future.

University of Pennsylvania researchers have been searching for ways to prevent and reverse periodontitis. In a report published in the Journal of Immunology, they describe a promising new target: a component of the immune system called complement. Treating monkeys with a complement inhibitor successfully prevented the inflammation and bone loss that is associated with periodontitis, making this a promising drug for treating humans with the disease.

The Right Way to Store Your Toothbrush

There are hundreds of dental care programs created to educate young children on the proper routines for healthy teeth. Many of these programs teach kids the best practices for brushing their teeth and recommend turning off the water faucet while brushing. However, one of the most important dental health tips is often overlooked. This article shares how important it is to teach children how to properly store tooth brushes.

Appropriate toothbrush storage and care are important to achieving personal oral hygiene and optimally effective plaque removal, says Maria L. Geisinger, DDS, assistant professor of periodontology in the School of Dentistry at the University of Alabama at Birmingham. "The oral cavity is home to hundreds of different types of microorganisms, which can be transferred to a toothbrush during use," Geisinger said. "Furthermore, most toothbrushes are stored in bathrooms, which exposes them to gastrointestinal microorganisms that may be transferred via a fecal-oral route. The number of microorganisms can vary wildly from undetectable to 1 million colony-forming units (CFUs). Proper handling and care of your toothbrush is important to your overall health."

Teeth Aid in Anthropology Efforts

Teeth have been a key factor in research for evolutionary anthropologists. Recently, a group of scientists have uncovered astounding information garnered from the fossil records of teeth found in historical skulls. This article details the research of Duke University anthropologists and their recent developments on growth bands found in teeth.

By comparing the human genome with those of five other primate species, a team of geneticists and evolutionary anthropologists at Duke University has identified two segments of DNA where natural selection may have acted to give modern humans their thick enamel. Teeth have been an invaluable resource for scientists who study evolution, the authors said. "The fossil record is always the most complete for teeth," said coauthor Christine Wall, associate research professor of evolutionary anthropology at Duke. "And enamel thickness has long been a key trait used to diagnose fossil hominins and reconstruct their diets and life histories."
