Our data support the relationships between metabolic disturbances and periodontitis, with a central role of insulin resistance.

Plaque index, reflecting dental plaque, and PD, closely linked with periodontal inflammation and infection, are statistically associated with high BMI and obesity, independently of dietary patterns and insulin resistance.

Objective: Carotid-femoral pulse wave velocity (PWV) is the gold standard method for determination of arterial stiffness. Correct PWV determination critically depends on the measurement of the arterial pathway travelled by the pulse during a certain transit time. Path lengths are commonly determined by tape measure, which may not correspond to anatomical path lengths. This study investigates the correspondence between the travelled arterial length obtained from magnetic resonance imaging (MRI) images with commonly used body-surface distances obtained by tape measure.Design and Method: MRI path lengths were obtained in 46 subjects (20 men; age 21 to 68) through centreline fitting of the artery lumen from ascending aorta (AA) to the femoral (FA) and carotid artery (CA) using a custom developed Matlab1 interface. The MRI-measured (AA-FA) -(AA-CA) length (the arterial segment travelled in carotid-femoral PWV measurement) was compared to 4 commonly used tape-measures. Results: See table.Conclusions: In the present population sample the distance from suprasternal notch over umbilicus to the femoral artery minus the distance between suprasternal notch and the carotid artery provides the best approximation of the real aortic path length.
