Outline of Final Research Achievements

The opportunities have increased for the patients with diabetes to be subject to orthodontic treatment. The differences between healthy animals and diabetic animals was studied with respect to the response of the small blood vessels to mechanical stimuli. Male Syrian golden hamsters were used as an animal. Diabetes was induced by intraperitoneal injection of streptozotocin. As intermittent mechanical stimulation to dorsal skin tissues, the load time of 1 second and then a varied non-load time from 9 seconds to 59 seconds were applied. The change of capillary diameter, the change for the bleeding tendency and blood vessels disappearance were compared between the healthy and the diabetic groups. As a result, it became clear that it is needed for the diabetic group to set a longer non-load time than the normal group, as intermittent orthodontic stimulation leading to normal bone resorption.
