Associations of Remaining Teeth Number, Periodontal Disease, and Occlusal Support Status with Erectile Dysfunction in Community-Dwelling Men

Abstract

Abstract Several systematic reviews and meta-analyses have reported positive relationships between erectile dysfunction (ED) and periodontal disease. Although occlusal support status and the number of remaining teeth also reflect oral conditions, no study has evaluated the relationship between these oral conditions and ED. The aim of the present study was to investigate these relationships in community-dwelling men. This cross-sectional 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. The median age was 53 years. Of the 400 men, 333 (83%) were classified into ED group. 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). In conclusion, poor occlusal support status was significantly associated with ED, as opposed to remaining teeth number and periodontal health status.
