Erectile dysfunction is defined as the inability 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 the alveolar bone and connective tissue that surrounds and sustains the tooth and leads to its loss.
In this disease, periodontal bacteria or inflammatory cytokines originating from the gingival focus injure the vascular endothelium. When this endothelial dysfunction occurs in the vessels of the penis, the blood flow in this organ is disturbed and sexual impotence occurs.
158 volunteers participated in the study: 80 men with erectile dysfunction treated in the Department of Urology of the San Cecilio Hospital of Granada and another 78 that were part of the control group. Socio-demographic data were collected, periodontal examination and analysis were performed to measure testosterone levels, lipid profile, C-reactive protein, glycemia and glycosylated hemoglobin. The results showed that 74% of patients with erectile dysfunction had periodontitis. The patients with greater dysfunction presented greater periodontal lesion.
According to the results, male periodontitis was 2.28 times more likely to suffer sexual impotence than periodontally healthy, and the associated biochemical variables were triglyceride, C-reactive protein and glycosylated hemoglobin levels.
Gingivitis is an oral disease caused by the bacterium Porphyromonas gingivalis, which causes inflammation and bleeding of the gums, and which can cause loss of teeth. And now, a team at the University of Louisville has found a link between this oral disorder and Alzheimer's disease. In tests with mice, the researchers noted that the oral infection caused by this bacterium could also colonize the brain and stimulate the appearance of beta-amyloid protein plaques, a major cause of Alzheimer's disease.
