Periodontal disease is commonly diagnosed in dogs and has been associated with systemic lesions in several organs, however, studies correlating this oral condition with heart disease in the canine species are still scarce in the scientific literature. Thus, the objective of the present study was to evaluate such correlation in adult dogs, through serial echocardiographic exams and, nonetheless, to analyze the influence of dental treatment on cardiac function. For this, 60 dogs were used, distributed in two groups, the control (CG, n = 30: presence of periodontal disease, not submitted to oral treatment) and the treated (GT, n = 30: presence of periodontal disease and submitted to oral treatment). The animals of the CG were paired with those of the GT in terms of race, weight, age and degree of periodontal disease. Baseline echocardiographic examinations (D0) of the CG were performed and after 30 days (D30). In GT, examinations were also performed at D0 and D30, however, they were submitted to periodontal treatment after baseline measurements. The echocardiographic exams were performed at the Veterinary Cardiology Laboratory of the Veterinary Hospital of the University of Franca, to record and analyze the interventricular septum in diastole (SIVd), interventricular septum in systole (SIVs), diameter of the left ventricle in diastole (DVEd), left ventricular diameter in systole (EVDs), left ventricular free wall in diastole (PVEd) left ventricular free wall in systole (PVEs) shortening fraction of left ventricle (FS), final diastolic volume (VDF), final stroke volume (VSF), ejection fraction (EF), maximum pulmonary artery pressure gradient (max. GP AP) and left atrial and aortic artery diameter ratio (EA-AO). The results of the CG were statistically compared with those of the GT by means of simple analysis of variance (ANOVA). The data obtained regarding the SIVs, DVEd and PVEs parameters of the GT dogs at D30 showed a statistically significant decrease (p<0.05) when compared to the D30 of the CG. Thus, given the established methodology and the results found, it is possible to infer that periodontal treatment may benefit some cardiac parameters of adult dogs, improving their quality of life and survival.
