An essential component of orthodontic therapy, orthodontic archwires may operate as surfaces for bacterial adhesion, which might result in issues with oral health.
This study assessed the bacterial adhesion to three different kinds of orthodontic archwires: beta-titanium (TMA), nickel-titanium (NiTi), and stainless steel (SS). At the conclusion of the clinical usage period, samples of each kind of archwire were gathered and submitted to microbiological investigation in order to determine the quantity of adhering bacterial colonies. Using scanning electron microscopy (SEM), the surface properties of the archwires were evaluated after usage.
The three kinds of archwires had significantly different rates of bacterial adhesion, according to the findings. With an average of 1500 ± 50 CFU/mm, SS archwires showed the highest level of bacterial adhesion, followed by NiTi archwires at 1100 ± 45 CFU/mm. The least amount of bacteria adhered to TMA archwires, with an average of 800 ± 30 CFU/mm. According to SEM pictures, the degree of bacterial adhesion was associated with the archwires' surface roughness, with smoother surfaces showing less bacterial colonization.
In comparison with SS and NiTi archwires, the research finds that TMA archwires are linked to the least amount of bacterial adhesion.
正畸弓丝是正畸治疗的重要组成部分，可能作为细菌黏附的表面，这可能导致口腔健康问题。
本研究评估了细菌对三种不同类型正畸弓丝的黏附情况：β钛（TMA）、镍钛（NiTi）和不锈钢（SS）。在临床使用期结束时，收集每种弓丝的样本并进行微生物学调查，以确定黏附细菌菌落的数量。使用扫描电子显微镜（SEM）在使用后评估弓丝的表面特性。
根据研究结果，三种弓丝的细菌黏附率有显著差异。不锈钢弓丝的细菌黏附水平最高，平均为1500±50 CFU/mm，其次是镍钛弓丝，为1100±45 CFU/mm。β钛弓丝黏附的细菌数量最少，平均为800±30 CFU/mm。根据扫描电子显微镜图片，细菌黏附程度与弓丝表面粗糙度有关，表面越光滑，细菌定植越少。
与不锈钢和镍钛弓丝相比，研究发现β钛弓丝的细菌黏附量最少。
