牙间隙不同清洁方法效果比较

目的 比较慢性牙周炎患者使用牙间刷或牙线去除菌斑、改善牙周炎症的效果.方法 将61例牙周炎患者进行1次10 min口腔刮治术后,随机分为两组,分别用牙间刷或牙线作为每日刷牙的辅助手段,6周后复查牙周参数.结果 与基线比较,6周后两组牙菌斑指数(PI)、Eastman牙间出血指数(EIBI)、探诊深度(PD)、探诊出血(...

Comparison of interdental cleaning methods

Objective To compare the effects of a customized interdental brushing technique and a customized flossing technique on clinical periodontal outcomes in chronic periodontitis cases.Methods Totally,61 patients with chronic periodontitis after receiving a 10-minute hand scaling to remove easily accessible calculus deposits were assigned either to a group,using interdental brushing technique as adjuvant of toothbrushing,or to a group using flossing technique.Such parameters as plaque index(PI),relative interdental papillae level(RIPL),Eastman interdental bleeding index(EIBI),probing depths(PD) and bleeding on probing(BOP) were measured before and after 6-week intervention.Results There were significant reductions from baseline for PI,EIBI,PD and BOP in both groups,while RIPL was significantly increased(P<0.01 for all).At 6th week,the interdental brush group improved more than the floss group in every parameter(P<0.05 for all).Conclusion Patients with chronic periodontitis can benefit from interdental cleaning,particularly using interdental brushes.
