Background Angiotensin‐converting enzyme ( ACE ) downregulates the activity of bradykinin, a potent proinflammatory and immunostimulatory peptide liberated from an internal portion of kininogens. Here, we asked whether periodontitis is worsened in patients under antihypertensive treatment with ACE inhibitors. Methods Periodontal parameters were recorded from 30 individuals taking ACE inhibitors (case) and 35 taking a non‐ ACE inhibitor medication (control). Data were analyzed by nonparametric and parametric statistical tests. Results Most sociodemographic figures were similar in both groups. However, family income was statistically higher in the control group, and the percentage of sites with visible plaque (PL) was statistically higher in the case group ( P = 0.043 and P = 0.005, respectively). The prevalence of individuals with chronic periodontitis varied from 31.5% in the control group to 63.4% in the case group ( P = 0.001). Patients in the case group presented a 3.2‐fold higher risk of having sites with pocket depth ≥5 mm and a 2.9‐fold higher risk of having sites with clinical attachment loss ≥5 mm in comparison with those in the control group ( P = 0.009 and P = 0.001, respectively; adjusted for family income and visible PL). Conclusion Angiotensin‐converting enzyme inhibitors may increase the prevalence and extent of chronic periodontitis in Brazilian patients.
