Abstract

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.
