Infections after implant placement are the main reasons for the failure of implant treatments. The present study aimed to evaluate the antibacterial effects of nanocurcumin inside the implant fixture against Escherichia coli, Staphylococcus aureus, and Enterococcus faecalis.
Twenty seven implants were classified in three groups for testing the antibacterial effect of nanocurcumin, chlorhexidine (as negative control), and distilled water (as negative control). Each group was then divided into three subgroups to study the effect of the applied torque on the antimicrobial effect of nanocurcumin. All implant abutment assemblies were submerged in bacteria suspension and were incubated at 37°C for 24 hours. The contents of each implant were removed to count the colony of bacteria on the surface of plates containing nutrient agar.
Results indicated that the inhibitory rate of bacteria by nanocurcumin was above 99% in all bacteria. Besides, by increasing the amount of applied torque from 10 to 35 N.cm, the CFU of bacteria in exposure to nanocurcumin significantly were decreased (p-value < 0.01).
The results of this study revealed that nanocurcumin can be used inside the implant fixture in order to use antimicrobial effects and further stabilization and success of the implant.
种植体植入后感染是种植体治疗失败的主要原因。本研究旨在评估纳米姜黄素在种植体器械内对大肠杆菌、金黄色葡萄球菌和粪肠球菌的抗菌作用。
将 27 个种植体分为三组,以测试纳米姜黄素、洗必泰(阴性对照)和蒸馏水(阴性对照)的抗菌效果。然后,每组分为三个亚组,以研究施加扭矩对纳米姜黄素抗菌效果的影响。所有种植体基台组件均浸入细菌悬浮液中,在 37°C 下孵育 24 小时。取出每个种植体的内容物,在含有营养琼脂的平板上计数细菌表面的菌落。
结果表明,纳米姜黄素对所有细菌的抑菌率均在 99%以上。此外,随着施加扭矩从 10 增加到 35N·cm,暴露于纳米姜黄素的细菌 CFU 显著减少(p 值<0.01)。
本研究结果表明,纳米姜黄素可用于种植体器械内部,以利用其抗菌作用,进一步稳定和成功植入种植体。
