To produce evidence on an association between the number of teeth and selected cardiovascular risk factors among an elderly population.
The study population comprised of 523 community-living elderly people who participated in the population-based Kuopio 75+ study. The data for each subject were collected using a structured clinical health examination, an interview and laboratory tests. Linear regression models were used to estimate adjusted mean values and confidence limits.
Edentulous persons and persons with a small number of teeth had lower serum HDL cholesterol and higher triglyceride, leucocyte and blood glucose levels and a higher body mass index (BMI) compared with subjects to a large number of teeth.
The study showed that, in the Finnish home-dwelling population aged 75 years or older, those with a large number of teeth were less likely to have cardiovascular risk factors such as a low serum HDL cholesterol level, a high triglyceride level and a high BMI than did subjects with a small number of teeth or who were edentulous.
