This one-month clinical trial was designed to compare the effect of an electromechanical flossing device and manual flossing on reducing interproximal gingival bleeding and plaque accumulation in a cohort of 60 healthy adults. After baseline evaluation of interproximal gingival bleeding, soft tissue trauma and plaque, patients were randomly assigned to one of the two experimental groups, given flossing instructions, and had their teeth cleaned. At 30 days all three clinical parameters were again evaluated. The results showed a reduction in GI from baseline to follow-up in each group. This effect is significant (p<0.0001) in the analysis of variance. There was no overall difference in the groups (p=0.93). There was no difference in the reduction in GI from baseline to follow-up between the two groups (p=0.91); interaction). As with the GI, there was a significant reduction in PI from baseline to follow-up in each group (p<0.0001). There was no overall difference between the groups (p=0.24). There was no difference in the reduction in PI from baseline to follow-up between the two groups (p=0.59; interaction). No soft tissue trauma was noted at the baseline examination or at the follow-up examination after 30 days.
这项为期一个月的临床试验旨在比较电动牙线清洁装置和手动牙线清洁对60名健康成年人牙间隙牙龈出血和牙菌斑积聚的减少效果。在对牙间隙牙龈出血、软组织损伤和牙菌斑进行基线评估后，患者被随机分配到两个实验组之一，接受牙线清洁指导，并进行牙齿清洁。在30天时，再次评估所有三项临床参数。结果显示，每组从基线到随访时牙龈指数（GI）均有所降低。在方差分析中，这种效果具有显著性（p<0.0001）。两组之间无总体差异（p=0.93）。两组从基线到随访时牙龈指数降低情况无差异（p=0.91；交互作用）。与牙龈指数情况相同，每组从基线到随访时菌斑指数（PI）均显著降低（p<0.0001）。两组之间无总体差异（p=0.24）。两组从基线到随访时菌斑指数降低情况无差异（p=0.59；交互作用）。在基线检查或30天随访检查时均未发现软组织损伤。
