Some peritoneal dialysis (PD)-related peritonitis cases are thought to be caused by the pathogens in the oral cavity; however, the relationship between peritonitis and oral hygiene habits is unclear. In this study, we retrospectively examined the relationship between oral hygiene habits and peritonitis in patients who agreed to a questionnaire survey. Of the 75 patients, 37 patients developed PD-related peritonitis during the observation period. Peritonitis-free survival was significantly higher in patients who spent more time on oral hygiene daily and in patients who replaced their toothbrush more frequently (P < 0.05). According to multivariable analysis, increased daily oral hygiene duration and more frequent toothbrush replacement were associated with a significantly (P < 0.01) lower risk for peritonitis (hazard ratio [HR] 0.37 [95% CI, 0.18–0.77] and HR 0.35 [95% CI, 0.17–0.70], respectively). In conclusion, PD patients with superior oral hygiene habits showed a lower risk for PD-related peritonitis.
