Maintaining oral hygiene is very important during orthodontic therapy mouthwashes are prescribed as an adjunct to improve patient's oral hygiene. Commercially available mouthwashes e.g. Chlorhexidine, Listerine, fluoride containing mouthwashes have shown to alter the surface characteristics of orthodontic wires. Hence the purpose of the study was to evaluate the effect of Noni mouthwash on surface quality and compositional changes of Nickel Titanium orthodontic wires.
In this in vitro study pre-formed 0.014 inch NiTi arch wire was used. The study comprised of two samples, one control and one test sample which were 25mm in length. Control sample was stored at room temperature without any manipulation while test sample was immersed in Noni mouthwash solution for 1.5 hours, after which the test specimen was removed from the mouthwash solution and rinsed with distilled water. Both control and test samples were sent for scanning electron microscopy analysis, to qualitatively characterize the topography of the wire surface. Electron dispersion spectrum analysis was done to evaluate the various components of both the wires.
No significant difference in the average surface roughness for both wire samples was observed. There was no significant difference seen in the composition of wire after immersion in Noni mouthwash.
Noni mouthwash did not have significant influence on the surface roughness or altered the composition of the Ni-Ti wire. Hence Noni mouthwash may be prescribed as a natural, non-destructive prophylactic agent for orthodontic patients.
在正畸治疗期间保持口腔卫生非常重要，漱口水被作为辅助手段来改善患者的口腔卫生。市售漱口水，如洗必泰、李施德林含氟漱口水，已显示会改变正畸钢丝的表面特性。因此，本研究的目的是评估诺丽漱口水对镍钛正畸钢丝表面质量和成分变化的影响。
在本体外研究中，使用预先制作的0.014英寸镍钛弓丝。该研究包括两个样本，一个对照样本和一个测试样本，长度均为25毫米。对照样本在室温下储存，不进行任何处理，而测试样本浸泡在诺丽漱口水溶液中1.5小时，之后从漱口水溶液中取出测试样本，并用蒸馏水冲洗。对照样本和测试样本均送去进行扫描电子显微镜分析，以定性表征钢丝表面的形貌。进行电子能谱分析以评估两根钢丝的各种成分。
两个钢丝样本的平均表面粗糙度没有显著差异。浸泡在诺丽漱口水后，钢丝的成分没有显著差异。
诺丽漱口水对镍钛钢丝的表面粗糙度没有显著影响，也没有改变其成分。因此，诺丽漱口水可作为正畸患者的天然、无损预防剂开出处方。
