CHICAGO – January 9, 2007 – Mothers who breastfeed should be sure to have enough calcium in their diet, or they may risk bone loss around their teeth and gums, according to a new study that appears in the January issue of the Journal of Periodontology (JOP). Study Abstract *

Researchers from Tohoku University in Japan investigated if lactation affects alveolar bone loss, the bone surrounding the roots of teeth, in rat models of experimental periodontitis. They found mothers who are lactating could put the bone structures around their teeth at risk, especially when there was not enough calcium in their diet.

“Our research emphasized the importance of having a high-calcium diet while breast-feeding,” said Dr. Kanako Shoji, Division of Periodontology and Endodontology at Tohoku University. “While our study was on a rat population, the evidence confirmed that breastfeeding can cause increased bone loss in the mother, especially when the mother has insufficient calcium intake. But additional studies in human populations are necessary to confirm these findings.”

The study showed that all groups with insufficient Calcium intake saw an acute inflammatory reaction in periodontal tissues and disruption of the gingival epithelium, the tissues surrounding the teeth, in addition to increased attachment loss, and increased alveolar bone loss. Those groups which were lactating saw even greater attachment loss and bone loss.

“We know a high-Calcium diet can promote healthy teeth and gums,” said Dr. Preston D. Miller, DDS, President of the American Academy of Periodontology, “But this research indicates that nursing mothers should be especially conscious of having enough Calcium in their diet. While breast milk is critical to their baby’s bone development, mothers should be sure to have enough calcium, or risk bone loss in her mouth, which can worsen periodontal diseases. Given that a thorough periodontal evaluation should be done as soon as a woman finds out that she is pregnant, monitoring periodontal tissues, including more frequent cleanings during pregnancy and continuing until 3 months after delivery, will help assure periodontal health.”

CHICAGO – February 21, 2006 – People have a new reason to stick to their New Year’s resolution to lose excess weight besides fitting into the latest fashion trends. Researchers from University at Buffalo found that obesity is a significant predictor for periodontal disease, independent of age, gender, race, ethnicity, and smoking. This study printed in a recent supplement to the Journal of Periodontology (JOP).

Furthermore, analysis of this national sample suggests that insulin resistance mediates the relationship between obesity and periodontal disease. It was found that the severity of periodontal attachment loss increased proportionally with increasing insulin resistance. In addition, the number of teeth lost increased significantly with increasing levels of insulin resistance. Individuals in the highest insulin resistance category lost 1.1 more teeth compared to individuals in the lowest category.

“People who have a higher body mass index produce cytokines (hormone-like proteins), that lead to systemic inflammation and insulin resistance,” said Robert J. Genco, vice provost at the University at Buffalo and editor of the JOP. “We propose that chronic stimulation and secretion of proinflammatory cytokines associated with periodontal infection also occurs, contributing to insulin resistance, which may further predispose to diabetes mellitus.”

Genco and his research team recently showed that diabetics with periodontal disease may have greater mortality from diabetic complications such as cardiovascular disease and kidney complications than diabetics with little or no periodontal disease.

“The presence of periodontal infection combined with obesity may contribute to type 2 diabetes and its complications, such as coronary heart disease,” said Kenneth A. Krebs DMD and AAP president. “Although further studies are needed, people should remember that living a healthy lifestyle along with daily brushing and flossing and visiting your oral health care provider is always in fashion.”

Background Information

A total of 12,367 non-diabetic individuals 20 to 90 years old participated in the dental section of the NHANES III study. Of these 53 percent were men and 47 percent were women and 43 percent of all the individuals were overweight.
