Comparative analysis of iRoot BP Plus and MTA in revascularization of immature permanent teeth

Objective To compare the application of iRoot BP Plus and inorganic trioxide polymer (MTA) in immature permanent teeth with pulp revascularization. Methods A total of 100 patients (100 teeth) with pulp revascularization in our hospital were selected. According to the use of filling materials, there were 50 cases in MTA group (50 teeth, 2 cases lost to follow-up) and 50 cases in iRoot BP Plus group (50 teeth, 1 case lost to follow-up). The root development, root canal wall thickness and root length, old periapical index (O-PAI) changes at different time, clinical efficacy and complications were compared between the two groups. Results The developmental typing of iRoot BP Plus group was better than MTA group (χ²=2.21,P<0.05); the measurement results of root canal wall thickness, root length and growth rate in iRoot BP Plus group were higher than those in MTA group (t=3.511, 3.342, 9.983, 10.638, P<0.05). The O-PAI rating of iRoot BP Plus group at 12 months and 24 months was lower than that of MTA group (t=8.570, 8.268, P<0.05). The total effective rates of MTA group and iroot BP plus group were 89.80% and 97.96% respectively, and the difference was statistically significant (χ²=4.461,P<0.05). The incidence of complications in MTA group and iRoot BP Plus group were 32.65% and 6.12% respectively, with significant difference (χ²=20.854,P<0.05). Conclusion iRoot BP Plus has better effect than MTA on immature permanent teeth with pulp revascularization. Moreover, it is more conducive to root development and control of complications.
