Abstract
Objective: To review the literature reporting the importance of the relationship between periodontal disease and diabetes mellitus. Results: The results showed that the bidirectional relationship between diabetes mellitus and periodontal disease is highly prevalent in the population. Etiological factors and physiological mechanisms prove the interference of one disease in the progression to another. The results also showed that non-surgical periodontal therapy can assist in glycemic control with a 0.2 to 0.4% reduction in HbA1c. For the success of this treatment in diabetic patients, it is necessary to combine the systemic condition control with the correct use of medical drugs and a healthy lifestyle. Conclusion: Numerous studies described the importance of dental follow-up in diabetic patients, both for the maintenance of oral health and for the collaboration of glycemic control. It is also worth highlighting the relevance of the need for a multidisciplinary approach of health professionals to control these conditions that affect a large portion of the population, as well as to clarify patients aboutthe benefit of treatment for both conditions.
