Effects of periodontal basic treatment on peritoneal dialysis in patients with periodontitis / 天津医药

ABSTRACT

Objective To investigate the local or systemic effects of initial periodontal therapy on peritoneal dialysis in patients with chronic kidney disease and periodontitis. Methods Sixty-one patients with both periodontitis and regular peritoneal dialysis were selected in this study and were randomly divided into observation group (n=31) and control group (n=30). Patients in observation group were given periodontal initial therapy (ultrasonic supragingival scaling and ultrasonic subgingival irrigation, drug, root planing, oral health education) and peritoneal dialysis treatment. Patients in control group were given only peritoneal dialysis treatment. Clinical parameters including plaque index (PLI), gingival index (GI) and probing depth (PD) were detected before and one month after treatment in two groups. The concentrations of high-sensitivity C-reactive protein (hs-CRP) in gingival sulcus fluid and serum samples were measured by immune transmission turbidity method in two groups. Results There were no significant differences in PLI, GI, PD, hs-CRP of gingival sulcus fluid, and serum hs-CRP before treatment between the two groups. After one-month initial therapy, all the indexes were decreased in observation group, which were significantly different compared with those before treatment (P<0.05). And all the indexes were significantly lower in observation group than those of control group. There were no significant differences in PLI, PD, GI, hs-CRP of gingival sulcus fluid, and serum hs-CRP between control group and observation group before treatment. Conclusion Periodontal initial treatment can improve the periodontal inflammation in patients with chronic kidney disease, and reduce the concentration of systemic inflammatory factor hs-CRP, decreasing the risk of infection.
