Good oral hygiene measures are important for successful orthodontic treatment. They involve various types of mouthwashes which have been reported to cause alteration of mechanical properties of archwires. This study aimed to evaluate the effects of a new kind of chlorine-dioxide-containing mouthwash on the mechanical properties and surface morphology of stainless steel orthodontic archwires against the already prevalent chlorhexidine mouthwash in the market.
Group A - Chlorhexidine mouthwash 0.2% (study), Group B - Chlorine Dioxide mouthwash (study), and Group C - Artificial Saliva (control). 42 specimens of 5 cm long 19x25 inch SS archwires were immersed in each group equally. Post immersion, the frictional force was analyzed in the universal testing machine for each group using custom-made acrylic jigs for 10 specimens. The remaining 4 specimens from each group were sent for surface morphology evaluation using an atomic force microscope.
Friction resistance evaluation for the archwires revealed a mean friction of 0.011 ± 0.0056 in Group A, 0.015 ± 0.0052 in Group B, and 0.010 ± 0.0067 in Group C. Results suggested that the static friction of Group C (control group) was found to be the least when compared with the experimental groups, although not producing statistically significant values. Surface roughness of archwires compared at a 10μm range revealed a mean roughness of 19.38 ± 0.82 in Group A, 25.39 ± 7.01 in Group B, and 16.65 ± 3.07 in Group C which shows there wasn't any statistically significant difference in the mean roughness midst the three sets.
Chlorine dioxide and Chlorhexidine mouthwashes caused an increase in the frictional resistance of the archwires when compared to the control group. When measured at a range of 10μm the mean surface roughness did not differ across the control and the experimental groups.
良好的口腔卫生措施对正畸治疗的成功至关重要。这些措施包括各种漱口水,据报道,它们会导致弓丝力学性能的改变。本研究旨在评估一种新型含二氧化氯漱口水对不锈钢正畸弓丝力学性能和表面形态的影响,并与市场上已普遍使用的洗必泰漱口水进行对比。
A组——0.2%洗必泰漱口水(研究组),B组——二氧化氯漱口水(研究组),C组——人工唾液(对照组)。将42根长度为5厘米、规格为19x25英寸的不锈钢弓丝样本平均分配到每组中浸泡。浸泡后,使用定制的丙烯酸夹具在万能试验机上对每组中的10个样本分析摩擦力。每组剩余的4个样本送去用原子力显微镜进行表面形态评估。
对弓丝的摩擦阻力评估显示,A组的平均摩擦力为0.011±0.0056,B组为0.015±0.0052,C组为0.010±0.0067。结果表明,与实验组相比,C组(对照组)的静摩擦力最小,尽管未产生统计学上的显著差异。在10μm范围内比较弓丝的表面粗糙度,A组的平均粗糙度为19.38±0.82,B组为25.39±7.01,C组为16.65±3.07,这表明三组之间的平均粗糙度没有任何统计学上的显著差异。
与对照组相比,二氧化氯漱口水和洗必泰漱口水会导致弓丝的摩擦阻力增加。在10μm范围内测量时,对照组和实验组的平均表面粗糙度没有差异。
