[NEWS, 28 September 2010] Teens with obesity are at increased risk of developing periodontal disease as a result of inflammation of the gums. This according to a study from Karolinska Institutet, recently published in International Journal of Pediatric Obesity.

In the study, a group of teenagers with obesity were compared with the same number of teenagers with normal weight. Participants were asked to answer a questionnaire on tooth brushing, smoking and other health issues. They also underwent a clinical examination for with respect to dental plaque, gingival inflammation, periodontal pockets and incipient alveolar bone loss. In addition their body mass index was estimated.

The results show that obesity in adolescence is associated with risk indicators for future periodontal disease. The researchers behind the study therefore underlines the importance of pediatricians and dentists working together to prevent overweight and obesity in children and adolescents. The study is a collaboration between the Department of Dental Medicine and the Department of Medicine, Huddinge, Karolinska Institutet.
