To assess in vitro the effect of manual and powered toothbrushes on the bond strength of orthodontic brackets.
Specimens of orthodontic brackets bonded to the surfaces of extracted teeth were exposed to one of two powered toothbrushes (Sonicare Elite, Braun Oral-B 3D Excel) or a manual toothbrush (Oral-B 35) for the equivalent of a 2-year exposure to brushing in the presence of toothpaste slurry. Control specimens underwent no brushing. For each treatment, 10 specimens were tested and evaluated. Shear bond strength of the orthodontic bracket to the tooth surface was assessed after exposure to simulated brushing. ANOVA was used to analyze the data.
No differences in orthodontic bracket bond strength were observed between any of the three treatments and the control. The evaluated toothbrushes did not adversely affect the in vitro bonding strength of orthodontic brackets, suggesting they are safe to use in orthodontic patients.
在体外评估手动牙刷和电动牙刷对正畸托槽粘结强度的影响。
将粘结在拔除牙齿表面的正畸托槽标本暴露于两种电动牙刷(飞利浦Sonicare Elite、博朗欧乐B 3D Excel)或一种手动牙刷(欧乐B 35)之一,在牙膏浆液存在的情况下,相当于进行2年的刷牙暴露。对照标本不进行刷牙。每种处理有10个标本进行测试和评估。在模拟刷牙暴露后,评估正畸托槽与牙齿表面的剪切粘结强度。采用方差分析来分析数据。
三种处理中的任何一种与对照组之间,正畸托槽粘结强度均未观察到差异。所评估的牙刷对正畸托槽的体外粘结强度没有不利影响,表明它们在正畸患者中使用是安全的。
