RESUMO
The goal of this review is to summarize the results of randomized trials reported since 2010 that assessed the effect of periodontal interventions on at least one systemic outcome in human subjects of any age, gender or ethnicity. Oral outcome measures included gingivitis, pocket depth, clinical attachment loss and/or radiographic bone loss and oral hygiene indices. Studies were excluded if the trial was not completed or if treatment was not randomized. The results suggest that nonsurgical periodontal intervention provided to pregnant women is safe and improves periodontal status without preventing adverse pregnancy outcomes. Nonsurgical periodontal intervention was also found to provide modest improvement in glycemic control in individuals with type 2 diabetes mellitus and periodontitis. Also, improving oral care through mechanical or chemical control of dental-plaque biofilm formation can contribute to the prevention of respiratory infections in differing clinical settings, including hospitals and nursing homes, and in patients with chronic obstructive pulmonary disease. No clinical trials were reported that tested the effect of periodontal interventions on medical outcomes of atherosclerosis, cardiovascular diseases, stroke, rheumatoid arthritis, Alzheimer's disease, chronic kidney disease or malignant neoplasia.
