Abstract

Objectives This study evaluated the efficacy of 3 reciprocating systems and the effects of 2 instruments for irrigant activation on filling material removal. Materials and Methods Forty mesiobuccal roots of maxillary molars were prepared up to size 25.06 and obturated. Micro-computed tomography (micro-CT) examination #1 was performed. Teeth were then divided into 4 groups (n = 10), according to the retreatment protocol: (1) manual, (2) Reciproc Blue, (3) WaveOne Gold, and (4) X1 Blue. Micro-CT examinations #2 and #3 were performed after filling removal and repreparation, respectively. Next, all teeth were divided into 2 new groups (n = 20) according to the irrigant activation protocol: XP Clean (XP Clean size 25.02) and Flatsonic (Flatsonic ultrasonic tip). Micro-CT examination #4 was performed after irrigant activation. Statistical analysis was performed with a significance level set at 5%. Results WaveOne Gold removed a significantly greater amount of filling material than the manual group (p < 0.05). The time to reach the WL was similar for all reciprocating systems (p > 0.05). X1 Blue was faster than the manual group (p < 0.05). Only manual group improved the filling material removal after the repreparation stage (p < 0.05). Both activation protocols significantly improved the filling material removal (p < 0.05), without differences between them (p > 0.05). Conclusions None of the tested instruments completely removed the filling material. X1 Blue size 25.06 reached the working length in the shortest time. XP Clean and Flatsonic improved the filling material removal.
往复器械和最终冲洗激活方案对上颌磨牙中颊根再治疗的疗效:微ct分析
目的本研究评估了3种往复系统和2种灌溉激活装置对填充物去除的效果。材料与方法制备上颌磨牙中颊根40根,尺寸25.06,封闭。进行微计算机断层扫描(micro-CT)检查#1。然后根据再治疗方案将牙齿分为4组(n = 10):(1) manual, (2) Reciproc Blue, (3) WaveOne Gold和(4)X1 Blue。Micro-CT检查#2和#3分别在填充物去除和重新准备后进行。然后根据冲洗激活方案将所有牙齿分为2组(n = 20): XP Clean (XP Clean尺寸25.02)和Flatsonic (Flatsonic超声尖端)。冲洗激活后进行显微ct检查#4。统计学分析,显著性水平设为5%。结果WaveOne Gold组的补牙量明显高于手工组(p < 0.05)。所有往复式系统到达终点的时间相似(p < 0.05)。X1 Blue比手工组快(p < 0.05)。只有手工组在补牙后补牙材料的清除率提高(p < 0.05)。两种活化方案均显著提高了充填材料的去除率(p < 0.05),两种活化方案间差异无统计学意义(p < 0.05)。结论所有检测器械均未完全去除充填材料。X1蓝色25.06尺寸在最短时间内达到工作长度。XP Clean和Flatsonic改进了填充材料的去除。
