Comparison of clinical and radiographic healing of periapical lesions using mta or conventional filling materials: Randomized controlled clinical trial

Abstract

Objectives: To compare the effect of Mineral Trioxide Aggregate (MTA) versus conventional filling materials on the healing of teeth with periapical lesions. Materials and methods: Sixty-four teeth with periapical lesions of greater than 5 mm were divided into two groups; G1) MTA (ProRoot MTA; Dentsply Maillefer, Ballaigues, Switzerland) filling, G2) conventional filling materials (n = 32/group). In MTA group, the apical portion of the root canal was filled with ProRoot MTA and the middle and coronal thirds of the root canal were filled with injectable thermoplasticized gutta-percha system. Patients were followed for 15 months. The data were statistically analyzed with Mann-Whitney U and chi-square test. Results: With a follow-up rate of 89.06% of all patients for 15 months, favorable outcomes were obtained in 100% in ProRoot MTA and 83.3% in conventional technique. Conclusions: ProRoot MTA showed better results compared to conventional filling materials in teeth with periapical radiolucency.
