The vast majority of periodontal diseases are inflammatory and can develop under the influence of both local causes and the combined action of common (endogenous) and local factors against the background of changes in the reactivity of the body. In the pathogenesis of the development of periodontal diseases in patients with diabetes, the main role is given to angiopathies. Since periodontitis is characterized by various vascular disorders, which are largely similar to diabetic angiopathy, it is not easy to prove the presence of the latter with periodontitis. So some authors argue this, while, others deny it. The starting point of diabetic microangiopathies is a violation of carbohydrate metabolism, as well as a violation of glycosamine metabolism, which determines the functional and structural integrity of the vascular basement membrane.
