In this pa.er, first, we a.dress limita.ions on a.typica. pa.ket cla.sifica.ion a.gorithm like Tuple Spa.e Sea.ch (TSS). Then, we present a.set of different scena.ios to pa.a.lelize it on different pa.a.lel processing pla.forms, including Gra.hics Processing Units (GPUs), clusters of Centra.

Experimenta. results show tha. the hybrid cluster provides the best pla.form for pa.a.lelizing pa.ket cla.sifica.ion a.gorithms, which promises the a.era.e throughput ra.e of 4.2 Million pa.kets per second (Mpps).

目的：比较不同冲洗方法对微创预备后根管内氢氧化钙封药的清除效果，为临床治疗提供参考。方法：使用Tru Na.omy镍钛系统对32个前磨牙进行微创根管预备后，向根管内封入氢氧化钙。根据不同冲洗方法将样本随机分为4组（n=8）：被动超声荡洗（PUI）组、声波荡洗（EDDY）组、XP-endo finisher(XPF)组、手用K锉（K File）组。冲洗前后拍摄CBCT，并对残余氢氧化钙进行定量计算，比较不同冲洗方法对氢氧化钙的清除效果。结果：所有冲洗技术应用后根管内均存在氢氧化钙残留，使用PUI、XPF、EDDY和K File之间存在显著差异（P <0.05）,PUI和XPF组的氢氧化钙残留量相对较少。结论：在微创预备后，使用PUI和XPF对根管内的氢氧化钙去除效果更好，但PUI的效率与XPF间无显著差异。
