Association between Chronic Periodontal Disease and Lower Urinary Tract Symptoms in Both Sexes.

OBJECTIVE: To investigate the relationship between chronic periodontal disease (CPD) and lower urinary tract symptoms (LUTS) in both sexes. METHODS: The interview sheet of the CPD self-checklist and LUTS was distributed to 600 adult men and women (300 each) who visited the first dental examination at dental clinics. The International Prostate Symptom Score (IPSS) questionnaire/Quality Of Life (IPSS/QOL) and Overactive Bladder Symptom Score (OABSS) were used to assess LUTS. The relationship between the CPD score and LUTS or OAB was examined. RESULTS: The interview sheet was collected from 88 men (50.9 +/- 16.6 years old) and 97 women (51.1 +/- 15.5 years old). There was no statistically significant correlation between the CPD score and age, or between the CPD score and the presence of LUTS in either men or women. However, urgency and weak stream score of IPSS were significantly correlated with the severity of CPD in both sexes. Significant correlation between the severity of CPD and the presence of OAB was only noted in men but not in women. CONCLUSIONS: The present study demonstrated for the first time that some storage and voiding symptoms were significantly associated with CPD in both sexes. Thus, although CPD and LUTS seem to have common pathophysiological factors, the interrelationship between CPD and LUTS is slightly different between men and women.
