Association of ED with chronic periodontal disease

To examine the relationship between chronic periodontal disease (CPD) and ED, the interview sheet including the CPD self-checklist (CPD score) and the five-item version of the International Index of Erectile Function (IIEF-5) was distributed to 300 adult men who received a comprehensive dental examination. Statistical analyses were performed by the Spearman's rank correlation coefficient and other methods. Statistical significance was accepted at the level of P<0.05. The interview sheets were collected from 88 men (response rate 29.3%, 50.9±16.6 years old). There was a statistically significant correlation between the CPD score and the presence of ED (P=0.0415). The results in the present study suggest that ED is related to the damage caused by endothelial dysfunction and the systematic inflammatory changes associated with CPD. The present study also suggests that dental health is important as a preventive medicine for ED.
