Background. This study investigated the association between periodontitis and organic erectile dysfunction (ED) in a sub-Saharan population. Methods. This multicenter analytical study lasted from April to September 2021. A total of 114 patients (38 cases and 76 controls) were recruited and matched on age, diabetes, and smoking status. Medical history and ED were recorded, as well as the plaque index, bleeding index, maximum interdental clinical attachment loss (CALmax), maximum probing depth, clinically detectable furcation involv ement, number of teeth in the mouth, number of teeth lost for periodontal reasons, and tooth mobility. The analysis was performed with SPSS 20.0 with a significance threshold set at 5%. Results. The two study groups were comparable regarding sociodemographic characteristics. Periodontitis was present in 76.31% of cases and 75% of controls without a significant difference (P=0.878). Logistic regression showed a significant association between high blood pressure and ED with an OR=4.78 (95% CI: 1.80‒12.70). Periodontitis was not associated with ED (OR=1.52, 95% CI: 0.55‒4.16); however, severe periodontitis was significantly associated with severe ED (OR=1.44, 95% CI: 1.11‒1.85, and OR=1.68, 95% CI: 1.15‒2.44, respectively for CALmax and tooth loss). Conclusion. Within the limits of this study, periodontitis was not associated with organic ED. However, the severity of periodontal disease significantly increased in patients with organic ED.
