The comparison of application of MTA and iRoot BP Plus in rootcanal therapy for refractory periapical disease of anterior teeth

: Objective To compare the effects of mineral trioxide aggregate (MTA) and iRoot BP Plus in rootcanal therapy of refractory periapical disease of anterior teeth. Methods The data of 246 patients with refractoryperiapical disease of anterior teeth admitted to the Department of Stomatology of the Affiliated Hospital of ChengdeMedical College from March 2016 to March 2018 were retrospectively analyzed. All patients had a single affectedtooth and all received retrograde filling therapy. Among them, eighty-two cases were treated with MTA (MTA group)and eighty-four cases were treated with iRoot BP Plus (iRoot BP Plus group). Besides, eighty cases in the controlgroup were treated with calcium hydroxide paste. The quality of root canal filling, local swelling and pain scoresbefore and 1 week after treatment, changes of old periapical indexes (O-PAI) at different time points and clinicalefficacy were compared. Results The percentage of adequate root canal filling in the iRoot BP Plus group wasgreater than that in MTA group and control group (P < 0.05). The differences of local swelling and pain scores before and one week after treatment in MTA group were higher than those in control group, and those in iRoot BP Plusgroup were the highest (P < 0.05). The O-PAI grade of iRoot BP Plus was lower than that of MTA group and controlgroup, which indicated relatively better therapeutic efficacy of iRoot BP Plus (P < 0.05), and the O-PAI grade ofMTA group after treatment was lower than that of control group (P < 0.05). Besides, the overall effective rate ofiRoot BP Plus group was the highest among the three groups (P < 0.05). Conclusion The iRoot BP Plus and MTAare better than calcium hydroxide paste in the treatment of refractory periapical disease of anterior teeth.Furthermore, the application of iRoot BP Plus is more likely to achieve adequate root canal filling, and caneffectively alleviate local swelling and pain and improve O-PAI. Thus, iRoot BP Plus is promising to replace MTAfor wider popularization and application.
