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(BOP)均值显著降低,而相对牙间隙乳头水平(RIPL)均值显著升高(均P<0.01)。牙间刷组上述参数基线与6周均数差值变化幅度显著大于牙线组(均P<0.05)。结论通过采取牙间隙清洁措施,慢性牙周炎患者获益明显。牙间刷在去除菌斑、改善牙周炎症方面的效果明显优于牙线。
Objective To compare the effect of periodontal inflammation by using an interdental brush or floss to remove plaque in patients with chronic periodontitis. Methods Sixty-one patients with periodontitis were treated with 10-min oral curettage. They were randomly divided into two groups. The interdental brush or dental floss was used as an auxiliary tool for daily brushing. The periodontal parameters were reviewed after 6 weeks. Results Compared with the baseline, mean plaque index (PI), Eastman interosseous hemorrhage index (EIBI), probing depth (PD) and probing bleeding (BOP) of the two groups decreased significantly after 6 weeks, (RIPL) mean significantly (all P <0.01). The change of the difference between baseline and 6-week mean value of the parameters in the interdental brush group was significantly greater than that in the floss group (both P <0.05). Conclusions Benefiting from chronic periodontitis benefits significantly through the use of interdental cleansing. Interdental brush in the removal of plaque, the effect of improving periodontal inflammation was significantly better than floss.
