Effect of Plaque Control on Chronic Periodontitis in Psychiatric Patients with Long-term Hospitalization

Objective: To study the effect of plaque control on chronic periodontitis in psychiatric patients. Methods: 116 psychiatric patients with chronic periodontitis in our hospital from March 2016 to April 2019 were selected as the research objects. All the patients were treated with ultrasonic curettage combined with minocycline hydrochloride ointment, and the patients were supervised to brush their teeth correctly every day. The clinical treatment effect, detection of periodontal pathogens in subgingival plaque and gingival crevices were observed after treatment. The levels of tumor necrosis facto-α(TNF-α), hypersensitive C-reactive protein(hs CRP) and interleukin-6(IL-6)in the fluid were measured, SBI) were observed and recorded. Results: After the treatment, the levels of PG, Aa, Fn, Tf, Pi, Td, were significantly decreased, and the difference was statistically significant(P<0.05). After treatment, the inflammatory factor index decreased significantly, and the difference was statistically significant(P<0.05).After treatment, PD, AL and SBI indexes decreased significantly, and the difference was statistically significant(P<0.05). Conclusion: Plaque control has a significant effect on psychosis patients with chronic periodontitis. It can improve the pathogenic bacteria in subgingival plaque and reduce the expression of inflammatory factors in the gingival crevicular fluid.
