Combine a diet high in sugar with poor oral hygiene habits and dental cavities, or caries, will likely result. The sugar triggers the formation of an acidic biofilm, known as plaque, on the teeth, eroding the surface. Early childhood caries is a severe form of tooth decay that affects one in every four children in the United States and hundreds of millions more globally. It's a particularly severe problem in underprivileged populations.

High vitamin D levels may decrease the risk of cancer development, particularly liver cancer, according to a new study.

 

The study reinforces the existing theory that vitamin D helps defend against certain cancers.

Exposure to sunlight stimulates the production of vitamin D by our skin. Vitamin D contributes to calcium level maintenance in our bodies, which in turn helps teeth, muscles and bones remain healthy.

Tobacco and alcohol use may be the most common cause of head and neck cancers, but a new culprit has come on the scene in recent years.

The human papillomavirus (HPV) is now responsible for more than 60 percent of cases of oropharyngeal cancer diagnosed at Penn State Milton S. Hershey Medical Center, according to Dr. David Goldenberg, professor of surgery and medicine and director of Head and Neck Surgery.

Oropharyngeal cancer can affect the back third of the tongue, the soft palate, side and back walls of the throat and the tonsils.

The chronic oral inflammatory disease periodontitis may be associated with human papillomavirus (HPV) status in individuals with head and neck squamous cell carcinoma (HNSCC), report researchers.

Their study findings show that among HNSCC patients, the odds for having HPV-positive tumors increased significantly with each millimeter of alveolar bone loss (ABL) - an established measure of periodontitis.

Tooth decay (cavities and dental caries) and gum disease are caused by colonies of bacteria that constantly coat the teeth with a sticky film called plaque. If plaque is not brushed away, these bacteria break down the sugars and starches in foods to produce acids that wear away the tooth enamel. The plaque also hardens into tartar, which can lead to gum inflammation, or gingivitis.
