(300) Relationships of Remaining Teeth Number, Periodontal Disease, and Occlusal Support Status with Erectile Dysfunction

Introduction Several systematic reviews and meta-analyses have reported positive relationships between erectile dysfunction (ED) and periodontal disease. However, no study has evaluated the relationship of occlusal support status and the number of remaining teeth with ED. Objective The aim of the present study was to investigate the associations between ED and the remaining teeth number, periodontal disease, and occlusal support status. Methods This study included 400 community-dwelling men. Periodontal health status and occlusal support condition were evaluated using the Community Periodontal Index (CPI) and Eichner classification. Multivariable analyses were performed to evaluate the relationships between ED and the remaining teeth number, periodontal disease, and occlusal support status. Results The median age was 53 years. Of the 400 men, 333 (83%) were classified into ED group. The CPI score in the ED group was significantly higher than that in the non-ED group (2.1 ± 1.2 vs. 1.7 ± 1.1, respectively; P = 0.015). A significant negative correlation was observed between CPI and IIEF-5 scores (ρ = -0.167, P = 0.001). Almost all men in the non-ED group were classified as Eichner Class A (96%), whereas 63%, 26%, and 11% of the men in the ED group were classified as Eichner Class A, B, and C, respectively. This difference in the Eichner class distribution between the non-ED and ED groups was statistically significant (P < 0001). Men with poorer occlusal support conditions had a significantly higher prevalence of ED (Eichner Class A: 77%, Class B: 97%, Class C: 100%; P < 0.001). In univariable analyses, remaining teeth number, CPI score, and Eichner classification were significantly associated with ED. In multivariable analyses, remaining teeth number (odds ratio [OR]: 0.907, P = 0.114) and CPI score (OR: 0.978, P = 0.864) were not significantly associated with ED, whereas the Eichner classification was independently and significantly associated with ED (OR: 3.490, P = 0.042). Conclusions Poor occlusal support status was significantly associated with ED in community-dwelling men, as opposed to remaining teeth number and periodontal health status. Disclosure No
