In this study, we examined the debriding effect of the action of vibrational acceleration on the plaque biofilm attached to titanium surface. Plaque biofilm were formed on titanium specimens by volunteers who kept the custom made stents intraorally for 72 hours on the buccal surfaces of molar and premolar teeth. The titanium surface was exposed to ultrasonic water flow for 180 seconds. For each titanium specimen, residual plaque biofilm (RPB) areas were evaluated as a percentage of the scanned surface selected at random by digital microscope. Ultrasonic water exposed titanium surfaces were observed by scanning electron microscope (SEM).Mean RPB was 19.0% and 16.2% on the mirror and rough surface respectively. A significant decrease in the RPB when compared to pretreatment on both mirror surface and rough surface *p<0.01, Tukey-Kramer (n=8). Additionally, the ultrasonic water flow resulted in complete disruption of the bacterial chain.

在这项研究中，我们研究了振动加速作用对附着在钛表面的斑块生物膜的清除效果。自制支架放置于磨牙和前磨牙颊面72小时后，在钛标本上形成菌斑生物膜。钛表面暴露在超声波水流中180秒。对于每个钛标本，通过数字显微镜随机选择剩余斑块生物膜（RPB）面积作为扫描表面的百分比进行评估。用扫描电镜（SEM）观察超声水暴露钛表面的形貌。镜面和粗糙表面的平均RPB分别为19.0%和16.2%。与镜面和粗糙表面预处理相比，RPB显著降低*p<0.01, Tukey-Kramer （n=8）。此外，超声波水流导致细菌链的完全破坏。
