基于PDSA循环的2型糖尿病伴牙周炎患者口腔健康管理研究OA

Objective:To evaluate the effectiveness of applying the PDSA(Plan-Do-Study-Act)cycle model in clini-cal oral interventions for improving oral health and glycemic control in patients with type 2 diabetes mellitus(T2DM)compli-cated with periodontitis.Methods:A prospective controlled study involving 120 patients with T2DM and chronic periodontitis was conducted.Participants were equally allocated to a PDSA intervention group(n=60)and a conventional guidance group(n=60).Plaque index(PLI),gingival index(GI),probing depth(PD),oral pH,fasting blood glucose(FBG),2-hour post-prandial blood glucose(2h-PBG),and glycated hemoglobin(HbA1c)were measured at baseline and after 12 weeks.Structured questionnaires were used to collect data on oral hygiene behaviors and intervention compliance.The PDSA group underwent six iterative cycles(one every 2 weeks):Plan→Do→Study→Act,with personalized oral functional rehabilitation training regi-mens optimized in each cycle.The control group received only one conventional oral hygiene guidance session.Results:After intervention,PLI,GI and PD in the PDSA group were significantly lower,and oral pH was significantly higher,than those in the control group(P<0.05).FBG,2 hPBG and HbA1c in the PDSA group were also significantly lower than those in the con-trol group(P<0.05).The PDSA group showed a higher rate of optimal oral hygiene(70.0％vs.46.7％),higher intervention compliance(90.0％vs.80.0％),and a lower complication rate(8.3％vs.21.7％)than the control group.Conclusion:Ap-plying the PDSA cycle model to oral health management in patients with T2DM and periodontitis,through continuous data-driven iterative optimization,can significantly improve oral health indicators and glycemic control,enhance intervention com-pliance,and reduce complications,providing a reproducible methodological reference for clinical promotion.
