摘要/Abstract

摘要： 目的: 评价MTA、iRoot BP Plus两种根管充填材料在根管正充填与倒充填两种不同根尖术式下的根管封闭效果。方法: :收集因牙周、正畸拔除并符合标准的下颌恒前磨牙40颗,根管预备后随机分为4个实验组(n=8)和2个对照组(n=4):A组(MTA 正充填组)、B组(iRoot BP Plus正充填组)、C组(MTA倒充填组)、D组(iRoot BP Plus倒充填组)、M组(阳性对照组)、N组(阴性对照组)。使用印度墨汁染色技术,透明牙技术评价两种材料在根管正充填与倒充填两种不同根尖术式下的根管封闭效果。结果: 各实验组根方均有不同深度的墨汁渗入,A、B组较C、D组微渗漏值稍大,但各组间差异无统计学意义(P>0.05)。结论: MTA 、iRoot BP Plus在根管正充填与倒充填两种不同充填方式下能取得同样的根尖封闭效果。因此,对于部分特殊部位的根尖病变以及止血困难等行根尖倒预备、倒充填较困难的病例可以选择MTA或iRoot BP Plus正充填后再行根尖切除这一手术方式作为有效的替代方式。

Abstract: Objective: To evaluate the root canal sealing effect of MTA and iRoot BP Plus in two different apical operations, i.e. root canal orthograde filling and retrograde root canal filling. Methods: Forty mandibular permanent premolars with single root canal were collected and randomly divided into four experimental groups (n=8) and two control groups (n=4) after root canal preparation. Group A was orthograde filled with MTA. Group B was orthograde filled with iRoot BP Plus. Group C was retrograde filled with MTA. Group D was retrograde filled with iRoot BP Plus. Group M was the positive control group. Group N was the negative control group. Indian ink staining technique and transparent tooth technique were used to evaluate the root canal sealing effect of two materials under two different conditions, i.e. root canal orthograde filling and retrograde root canal filling. Results: Different degrees of dye infiltration could be seen in each experimental group, and the microleakage in group A and B was slightly higher than that in group C and D, but there was no significant difference in apical leakage among different groups(P>0.05). Conclusion: MTA and iRoot BP Plus can achieve the same apical sealing effect under two different filling conditions. For some special apical lesions and difficulty in hemostasis, apical resection after MTA or iRoot BP Plus orthograde root canal filling can be chosen as an effective alternative.
