From EurekAlert! - Breaking News: Contrary to conventional wisdom, overweight children have fewer cavities and healthier teeth compared to their normal weight peers, according to a study published in this month's issue of Community Dentistry & Oral Epidemiology. Surprised researchers at the Eastman Dental Center, part of the University of Rochester Medical Center, conducted a secondary analysis of nearly 18,000 children who participated in two separate National Health and Nutrition Examination Surveys (NHANES III and NHANES 99-02). The study found no differences in rates of caries (tooth decay) among children ages 2-5 in all weight ranges, while children ages 6-18 who were considered overweight and at risk for becoming overweight showed a decreased risk of caries compared to their normal weight peers. Are their diets similar to normal weight peers but lead more sedentary lifestyles? Research to analyze both diet and lifestyle is needed to better understand the results." The study defined overweight children as being at the 95th or higher percentile for their age and sex; children at the 85th or higher percentile and less than 95th percentile for their age and sex were defined as at risk for becoming overweight. A world leader in residency training and research initiatives, the Eastman Dental Center each year treats thousands of Rochester-area patients by providing a full range of general and specialized dentistry including pediatrics, periodontology, oral and maxillofacial surgery, orthodontics and prosthodontics. Established in 1941, the Eastman Dental Center is the only major post doctoral dental education, research and clinical institution in the U.S. within an academic medical center.
