AIM: To investigate the effect of periodontal therapy on endothelial function of subjects with periodontitis in stages III or IV and established cardiovascular disease.
MATERIALS AND METHODS: A triple-blinded, parallel groups, randomized clinical trial of 6 months duration, on patients with history of coronary heart disease and periodontitis in stages III or IV was performed. Intervention consisted of steps 1 (oral hygiene instructions and professional mechanical plaque removal) and 2 (subgingival instrumentation) of periodontal therapy, including an antiseptic mouth rinse for 7 days. Patients in the control group received only step 1, with the adjunctive use of a fluoride-containing mouth rinse. Endothelial function (flow-mediated dilation [FMD]) and carotid intima-media thickness (cIMT) at baseline, 3 and 6 months, and serum markers of inflammation and cell adhesion at 3 days, 10 days, 3 and 6 months after therapy, were evaluated. Demographic characteristics, cardiovascular risk factors, history of cardiovascular diseases, medication intake, lipids profile, blood pressure, and periodontal outcomes were also evaluated. Student T, Mann-Whitney U, Chi-square and Fisher-exact tests were performed along with repeated measures ANOVA with post hoc Bonferroni's corrections.
RESULTS: Thirty-five patients were included. In the test group, improvements in pocket depth, bleeding on probing and suppuration at 6 months were significantly better than in control patients. Reductions in mean FMD [test group -3.43%; 95% confidence interval-CI [-2.68; 9.54], p = 0.487; control group -6.75%; 95% CI [1.29; 12.22], p = 0.012] and cIMT (test group -0.05 mm; 95% CI [0.01; 0.10], p = 0.014; control group -0.01 mm; 95% CI [-0.03; 0.05], p = 1.000) were observed in both groups from baseline to 6 months, without significant intergroup differences at any time-point. Differences between groups in serum inflammatory markers were detected at baseline and 3 days for interleukin (IL)-18, and at 10 days for IL-8.
CONCLUSION: Preliminary results from the present pilot study showed that steps 1 and 2 of periodontal treatment in subjects with periodontitis in stages III-IV and established cardiovascular disease induced improvements in cIMT and periodontal outcomes, although changes in FMD were not observed.
