This study compared different irrigation techniques in triple antibiotic paste (TAP) removal from root canals. Fifty-six maxillaryanterior-teeth were filled with TAP for 28 days, and assigned into 5 experimental groups (n=10): Syringe irrigation (SI), NaviTip FX (NFX), Vibringe-Syringe irrigation (V-SI), NaviTip FX-Vibringe (V-NFX), passive ultrasonic irrigation (PUI) and positive and negative control groups (n=3 for each). Following the removal of the medicament, the remaining medicament was evaluated using 4-grade scoring-system. V-NFX and NFX showed similar performances (p>0.05) while V-NFX was significantly more efficient than SI and PUI (p<0.05) at all parts of root canals. VSI was less efficient at apical part when compared to NFX and V-NFX (p<0.05) while not significantly different from PUI and SI at all parts of the root canals (p>0.05). Regarding different parts of the root canals, V-SI and PUI were significantly less efficient at the apical part (p<0.05). In conclusion, the brush form of irrigation delivery with and without sonic activation improved the removal of TAP from the root canals when compared to ultrasonic activation, syringe irrigation or sonic activation alone.
本研究比较了从根管中去除三联抗生素糊剂（TAP）的不同冲洗技术。56颗上颌前牙用TAP充填28天，并分为5个实验组（n = 10）：注射器冲洗（SI）、NaviTip FX（NFX）、振动注射器冲洗（V - SI）、NaviTip FX - 振动（V - NFX）、被动超声冲洗（PUI）以及阳性和阴性对照组（每组n = 3）。去除药物后，使用4级评分系统评估剩余药物。V - NFX和NFX表现相似（p>0.05），而在根管各部位，V - NFX均显著比SI和PUI更有效（p<0.05）。与NFX和V - NFX相比，V - SI在根尖部效率较低（p<0.05），而在根管各部位与PUI和SI无显著差异（p>0.05）。关于根管的不同部位，V - SI和PUI在根尖部效率显著较低（p<0.05）。总之，与单独的超声激活、注射器冲洗或声波激活相比，有或没有声波激活的刷状冲洗方式能改善从根管中去除TAP的效果。
