Glucose tolerance and the state of periodontal health

Relationship between bleeding/plaque ratio, family history of diabetes mellitus and impaired glucose tolerance

In the present study, the relationship between bleeding/plaque ratio, family history of diabetes mellitus and oral glucose tolerance pattern were investigated in 85 non-diabetic individuals without periodontal breakdown. In this group, no relationship between bleeding/plaque ratio, family history of diabetes mellitus and impaired glucose tolerance was found. The results of the present study suggest that the observed variation in bleeding/plaque ratio cannot be explained by impaired glucose tolerance or family history of diabetes mellitus. It is hypothesized that in subjects with impaired glucose tolerance, the periods of elevated blood glucose values may be too short to introduce tissue changes.

Diabetes mellitus and associated oral manifestations: a review

Oral research concerning diabetes mellitus has revealed a number of clinical implications. These include, among others, the need for more intense management of the diabetic patient with periodontal disease because tissue destruction may be accelerated, the need for rapid control of oral infection in these patients in order to prevent exacerbation of the existing metabolic imbalance, and the desirability of performing a screening for diabetes mellitus on all patients exhibiting asymptomatic parotid enlargement. Despite the explosion of knowledge concerning diabetes mellitus that has occurred since the discovery of insulin, its definitive etiology continues to elude the scientific community and its treatment remains in the realm of clinical management rather than in that of prevention and cure. In the past, research on diabetes has focused on the role of insulin in seeking the fundamental etiology of diabetes and its complications. With the progression of research, it has become apparent that the initiation and progression of the disease probably involve the interplay of a multiplicity of factors. Hereditary and immunologic factors, as suggested earlier, appear to be operated on by environmental factors, subsequently altering the body's metabolic milieu with widespread primary and secondary effects. Fertile areas for future oral research in diabetes mellitus will include, therefore, genetics, immunology, enzymology, and basement membrane pathology. On the cellular and molecular levels, particularly, the oral cavity and associated structures comprise a somewhat under-investigated area in diabetes mellitus research and, thus, hold great promise for increasing our knowledge of this complex disease.
