Abstract
The principal aim of this concise review is to provide an updated practical knowledge with reference to the relationship between diabetes mellitus and periodontal disease. It mainly outlines their characteristics and clarifies their interrelationship. Contemporary scientific research indicated that diabetes mellitus may increase the risk of periodontitis. On the other hand, a chronic periodontal disease may affect the natural development of diabetes. Various triggering and modifying factors can induce both diseases, and interindividual variances are involved in the risk of their progress. Well-controlled periodontal disease may enhance glycemic control in diabetics. On the other hand, improved glycemic control may lead to a well-controlled periodontal disease. It is essential to establish a good consultation between the dentist and the specialist responsible for a diabetic patient, efforts being made to evidence the interrelated impact of the diseases, whose control will lead to significant clinical results.
