The effect of iRoot BP Plus material combined with micro-apical surgery on refractory apical periodontitis

Objective The study aims to explore the curative effect of iRoot BP Plus material combined with microscopic apical surgery on patients with refractory periapical periodontitis. Methods 96 patients (101 teeth) with refractory periapical periodontitis admitted to our hospital from June 2018 to June 2019 were selected and divided into 32 cases in group A (34 teeth) and B according to the random number table method. There were 32 cases in group (33 teeth) and 32 cases in group C (34 teeth). All patients underwent microscopic apical surgery, group A was treated with mineral oxide aggregates as the backfill material, group B was treated with amalgam as the backfill material, and group C was treated with iRoot BP Plus as the backfill material. The old periapical index (O-PAI) and postoperative swelling and pain rate were compared among the three groups before and after surgery. Results The O-PAI indexes of the 3 groups at 6 months and 12 months after operation were lower than those before the operation (P<0.05), while the O-PAI indexes of group A were (1.20±0.51) at 6 months and 12 months after operation (1.09±0.21), the O-PAI indexes of group C were (1.05±0.44) and (1.12±0.26) at 6 months and 12 months after operation, respectively, which were lower than those of group B (P<0.05), group A and group C There was no significant difference in the O-PAI index between the 6 and 12 months after the operation of the group (P>0.05); the swelling and pain rates of the A and C groups were 17.65% and 11.76% respectively, which were lower than those of the B group. There was no significant difference in the swelling and pain rate of group A and group C at 1 week after operation (P>0.05). Conclusion For patients with refractory periapical periodontitis treated with micro-apical apical surgery, iRoot BP Plus is used as the apical filling material. The curative effect is similar to the use of mineral trioxide aggregate materials, which can reduce postoperative swelling and pain and promote root apex. Bone tissue recovery is worth promoting.
