Abstract

Objective: This laboratory study aimed to evaluate the effect of different mouthwash solutions on the surface and mechanical properties of NiTi arch wire.

Methods: This experimental study was conducted at the Department of Preventive Dental Sciences, College of Dentistry, Princess Nourah bint Abdulrahman University, Saudi Arabia from September 2023 to November 2023. A 30 mm NiTi wires in length with 0.017 × 0.022" in dimensions were selected and equally divided into four groups: Control (G₀) group wires were immersed in distilled water (DW); G₁ wires were immersed in antiseptic mouthwash; G₂ wires were immersed in fluoridated mouthwash; and G₃ wires were immersed in therapeutic mouthwash. Surface morphology, nanohardness, and flexural modulus were evaluated at 24-hours, four weeks, and eight weeks' time points. Data were statistically analyzed using a two-way analysis of variance (P<0.05).

Results: The arch wires immersed in DW showed insignificant effects on surface roughness, nanohardness, and flexural modulus at different time points. However, all the experimental groups showed a significant effect of time and immersion solutions on the said properties (P<0.05). At the end of eight weeks, G₃ showed the highest surface roughness (0.346 ± 0.032 µm) and the lowest nanohardness (1.350 ± 0.412 GPa) and flexural modulus (3.960 ± 0.140 MPa) compared to other study groups.

Conclusions: The efficiency of tooth realignment could be influenced by the detrimental influence of fluoride and hydrogen peroxide mouthwash solutions on superelastic NiTi arch wires.

不同漱口水对镍钛正畸钢丝表面形态、纳米硬度和弯曲模量的影响

目的：本实验室研究旨在评估不同漱口水对镍钛弓丝表面和机械性能的影响：本实验研究旨在评估不同漱口水对镍钛弓丝表面和机械性能的影响：本实验研究于 2023 年 9 月至 2023 年 11 月在沙特阿拉伯努拉-宾特-阿卜杜勒拉赫曼公主大学牙科学院预防牙科学系进行。选取长度为 30 毫米、尺寸为 0.017 × 0.022 英寸的镍钛丝，平均分成四组：对照（G0）组钢丝浸泡在蒸馏水（DW）中；G1 组钢丝浸泡在消毒漱口水中；G2 组钢丝浸泡在含氟漱口水中；G3 组钢丝浸泡在治疗漱口水中。分别在 24 小时、四周和八周的时间点对表面形态、纳米硬度和弯曲模量进行评估。采用双因子方差分析对数据进行了统计分析（PResults：浸泡在 DW 中的弓丝在不同时间点对表面粗糙度、纳米硬度和弯曲模量的影响不明显。与其他研究组相比，P3 的表面粗糙度（0.346 ± 0.032 µm）最高，纳米硬度（1.350 ± 0.412 GPa）和弯曲模量（3.960 ± 0.140 MPa）最低：氟化物和过氧化氢漱口水对超弹性镍钛弓丝的不利影响可能会影响牙齿矫正的效率。

期刊介绍： It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad. Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour. That is why many opinion makers among the medical and pharmaceutical profession use this publication to communicate their viewpoint.
