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： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
