PURPOSE
The aim of this study was to evaluate the effects of various prophylactic treatments of titanium implants on bacterial biofilm formation, correlating surface modifications with the biofilms produced by PAO1, , and bacteria isolated from saliva.
METHODS
Pure titanium disks were treated with various prophylactic procedures, and atomic force microscopy (AFM) was used to determine the degree to which surface roughness was modified. To evaluate antibiofilm activity, we used PAO1, , and saliva-isolated spp., , and .
RESULTS
AFM showed that the surface roughness increased after using the air-polishing device and ultrasonic scaler, while a significant reduction was observed after using a curette or polishing with Detartrine ZTM (DZ) abrasive paste. In addition, we only observed a significant (<0.01) reduction in biofilm formation on the DZ-treated implant surfaces.
CONCLUSION
In this study, both AFM and antibiofilm analyses indicated that using DZ abrasive paste could be considered as the prophylactic procedure of choice for managing peri-implant lesions and for therapy-resistant cases of periodontitis.
目的
本研究旨在评估钛种植体的各种预防性处理对细菌生物膜形成的影响，将表面改性与由PAO1以及从唾液中分离出的细菌所产生的生物膜相关联。
方法
对纯钛盘进行各种预防性处理，并用原子力显微镜（AFM）测定表面粗糙度的改变程度。为评估抗生物膜活性，我们使用了PAO1以及从唾液中分离出的 spp.、 和 。
结果
AFM显示，使用空气抛光装置和超声波洁牙器后表面粗糙度增加，而使用刮匙或用去垢剂ZTM（DZ）研磨膏抛光后观察到显著降低。此外，我们仅观察到DZ处理的种植体表面生物膜形成有显著（<0.01）减少。
结论
在本研究中，AFM和抗生物膜分析均表明，使用DZ研磨膏可被视为处理种植体周围病变和治疗抵抗性牙周炎病例的首选预防性方法。
