The objective of this study was to compare the microbial adhesion of different oral pathogens on different wires used in orthodontic treatment and to evaluate the potential of these pathogens to form biofilms on different types of orthodontic wires and brackets.
In this in vitro investigation, we calculated that the sample size for each group (i.e., those with brackets [metal braces, ceramic braces, and self-ligating braces] and wires [nickel titanium, titanium molybdenum, and stainless steel]) should be 15 individuals. Five types of microbes (, , , , and ) were used. Three types of brackets and three types of wires were used with five types of bacteria, and the process was repeated three times to collect the average.
No significant differences were observed in the mean concentrations of bacteria in the different brackets (p > 0.05) or in the mean concentrations in the different orthodontic materials used in these brackets. In contrast, there were considerable differences between the concentrations of bacteria in the wires and those in the brackets (p < 0.05).
Different wires and brackets have different associations with bacterial adhesion and concentration. The wires exhibited more substantial biofilm absorbance and concentrations than the brackets. The adhesion of biofilm may be a decisive factor when choosing a type of orthodontic wire, particularly for individuals at high risk of developing bacterial oral diseases, such as periodontal diseases and dental caries.
本研究的目的是比较不同口腔病原体在正畸治疗中使用的不同弓丝上的微生物黏附情况，并评估这些病原体在不同类型正畸弓丝和托槽上形成生物膜的潜力。
在这项体外研究中，我们计算出每组（即使用托槽的组[金属牙套、陶瓷牙套和自锁牙套]以及弓丝的组[镍钛合金、钛钼合金和不锈钢]）的样本量应为15人。使用了五种微生物（此处原文缺失具体微生物名称）。三种类型的托槽和三种类型的弓丝与五种细菌一起使用，该过程重复三次以收集平均值。
在不同托槽中细菌的平均浓度（p > 0.05）或这些托槽中使用的不同正畸材料的平均浓度方面，未观察到显著差异。相比之下，弓丝中细菌浓度与托槽中细菌浓度之间存在相当大的差异（p < 0.05）。
不同的弓丝和托槽与细菌黏附和浓度有不同的关联。弓丝比托槽表现出更高的生物膜吸光度和浓度。在选择正畸弓丝类型时，生物膜的黏附可能是一个决定性因素，特别是对于有患细菌性口腔疾病（如牙周病和龋齿）高风险的个体。
