牙周病维护期治疗中口腔健康教育与牙周袋内细菌分布的追踪观察

Oral health instruction and bacteria distribution in periodontal pocket during the periodontal maintenance

目的 :用细菌涂片法观察牙周病维护期中细菌分布变化 ,以及细菌分布与牙周病临床指标变化之间的关系。方法 :选择在维护期中牙周病复发的患者60名 ,随机分2组 ,实验组施以牙周基础治疗 +口腔卫生宣教强化 ,对照组只作牙周基础治疗 ,不作口腔卫生宣教 ,观察基线2周、3个月、6个月牙周病患者牙周袋内细菌分布和牙周病临床指标变化。结果 :2组临床指标均较基线时显著减少 (P<0.05) ,实验组PLI SBI PD B %均较对照组下降快。结论 :牙周病患者牙周袋内细菌分布、牙周病临床指标与牙周病的活跃期和静止期有相关性 ,两者结合 ,在牙周病维护期监测牙周病活跃性 。

Objective:The aim of our investigation was to study the different propertion of periodontal inflamation activity and quiescence in adults subgingival plaque and evaluate the clinical value of oral health instrction.Methods:60subgingival plaque samples from periodontal maintenance phase were monitored when scaling or/and root planning at baseline?2w?3m?6m.these patients were divided into two groups.One has oral health instruction.Another not.Results:Significant difference of subgingival microbial flora varied with the term of inflammaˉtion.Significant positive correlation between the percentage of spirochete and clinical assessˉments PD.SBI and PLI.While negative correlation between the percentage of cocci cell and three clinical assessments were observed.After single scaling or/and root planning found clinˉical assessments were varied correspondingly,especially at OHI group.Conclusion:Monitoring the shift of subgingival microflora and clinical assessments are a compatively reliable indicator of the periodontal activity.Oral health instruction is important for the maintaining health of periodontal tissue.
