Recently, researchers from the Department of Stomatology of Guizhou people’s Hospital and West China School of Stomatology of Sichuan University jointly published papers to observe the changes and clinical indicators of five suspected pathogens in patients with chronic periodontitis after scaling (SRP), including P.G., T.F., p.i., A.A., and T.D The relationship between improvement.
this study points out that the effective control of the amount of P.g, T.f and T.d is closely related to the improvement of PPD and BOP, suggesting that P.g, T.f and T.d can be used as a marker microorganism to evaluate the treatment effect of SRP.
this paper was published in the 28 volume 04 Journal of practical dentistry in 2012.
The method of this study is to treat 20 cases of chronic periodontitis with SRP, record the depth of periodontal exploration, loss of clinical attachment and the change of exploration bleeding before and 3 months after treatment, and semi quantitatively detect 5 kinds of suspected pathogenic microorganisms of subgingival periodontitis
The results of this study showed that the detection of PPD decreased by Ge; 2mm, P.G, T.f and T.D significantly (P < 0.05); 0.94) mm (P < 0.05). There was no significant relationship between the change of detection amount of P.I and A.A before and after treatment and the improvement of clinical indexes
