"Both vitamin D and calcium counteract deficiencies and reduce bone resorption," said Dr. Charles Hildebolt, Department of Radiology, Washington University School of Medicine, St. Louis, MO. "Numerous studies indicate that vitamin D and calcium deficiencies result in bone loss and increased inflammation. Inflammation is a well recognized symptom of periodontal diseases, which is why it has been suggested that calcium and vitamin D deficiency may be a risk factor for periodontal diseases."
Research shows that the best means of obtaining the required amount of vitamin D is from sunshine. According to the National Institutes of Health, season, geographic latitude, time of day, cloud cover, smog and sunscreen affect ultraviolet ray exposure and vitamin D synthesis. Ten to 15 minutes of sun exposure at least two times per week to the face, arms, hands or back is usually sufficient to provide adequate vitamin D. People who live in an area with limited sun exposure may want to eat foods fortified with vitamin D such as milk, eggs, sardines and tuna fish.
"We are not encouraging people to forego their sun protection, nor to spend prolonged periods of time in the sun" said Vincent J. Iacono, DMD and president of the American Academy of Periodontology. "According to the American Academy of Dermatology, there is no such thing as a total UV block. Even the most effective sunscreens currently on the market let through enough UV to allow for adequate vitamin D formatio
