Brushing teeth may help erectile dysfunction

Men with periodontitis are more likely to suffer erectile dysfunction, so a proper tooth brushing and proper oral hygiene can help prevent this type of male sexual impotence, according to a study conducted by researchers from the University of Granada.

Erectile dysfunction is defined as the inability in a male to have an erection due to organic, psychological causes or a combination of both. Periodontitis is a chronic inflammation of the gum with destruction of alveolar bone and connective tissue that surround and support the tooth and leads to loss of it. In periodontitis, the periodontal bacteria or the inflammatory cytokines originated in the gingival focus damage the vascular endothelium. When this endothelial dysfunction occurs in the vessels of the penis the blood flow in this organ is disturbed and impotence occurs.

In this study of 80 cases and 78 controls, sociodemographic data was collected, a periodontal examination and an analytical test were performed to measure testosterone levels, lipid profile, C-reactive protein, glycemia and glycosylated hemoglobin.

The scientists found that 74% of the patients with ED presented periodontitis, in such a way that the patients with higher ED had greater periodontal injury. Patients with periodontitis were 2.28 times more likely to suffer an ED than periodontally healthy patients. The biochemical variables that were associated with ED were triglyceride levels, C-reactive protein and glycosylated hemoglobin.

This study, the first carried out on this subject in the European population, was carried out within a doctoral thesis project, whose author was the dentist Amada Martín Amat and its directors, the professors Francisco Mesa (Stomatology) and Miguel Arrabal (Urology) .

The results have been published in Journal of Clinical Periodontology, the most important international scientific journal in periodontal research.
