摘　　要：目的研究在牙周维护治疗过程中不同的牙间隙清洁措施的菌斑控制效果。方法27名慢性牙周炎患者在牙周维护治疗中给予牙线、牙缝刷使用方法指导。24h内停止一切菌斑控制措施。24h后,使用改良Qiugley-Hein菌斑指数记录法,记录菌斑指数(plaque index,PLI)的基线水平。然后采用自身对照方法,随机分配一侧使用牙线,另一侧使用牙缝刷,记录经过牙线或牙缝刷清洁后邻间隙区域PLI。运用t检验对两组之间菌斑指数进行统计学分析。结果两组邻间隙区域清洁前基线水平差异无统计学意义(P>0.05)。清洁后,牙缝刷清洁侧PLI下降至0.44±0.27,牙线清洁侧PLI下降至1.01±0.30,两组之间差异有统计学意义(P<0.001)。结论对于处于牙周维护治疗过程中的慢性牙周炎患者来讲,与牙线相比,牙缝刷可以更有效地控制牙齿邻面菌斑。Objective To compare dental floss with interdental brushes on the interdental plaque removal capacity among patients with periodontal maintenance. Methods Twenty-seven individuals were selected from those patients receiving periodontal maintenance therapy. The patients were instructed on the use of dental floss and interdental brushes and performed the cleaning until they felt it was satisfactory using one instrument for each quadrant. In this single-blind randomized splitmouth study,subjects cleaned the interdental spaces with dental floss or interdental brushes individually under supervision after having abstained from all oral hygiene for 24 hours. Upon written agreement,the Silness and Ltie Plaque Index （PLI） in interdental spaces was recorded before and after cleaning. Mean values were calculated and compared by t test. Results There was no statistical difference between two groups at baseline. Both two instruments reduced plaque significantly. The final mean PLI was 0.44±0.27 and 1.01±0.30 for interdental brushes and dental floss used side respectively. The PLI values showed that interdental brushes used were significantly smaller than those floss used（P〈0.05）. Conclusions It may be concluded that,for individuals under periodontal maintenance eare,interdental toothbrushes are more effective in interdental supragingival plaque removal than dental floss.
