OBJECTIVES

The aim of this study was to compare the effects of mineral trioxide aggregate (MTA) and platelet-rich fibrin (PRF) use on periapical healing in surgically treated periapical lesions using three-dimensional (3D) cone-beam computed tomographic (CBCT) imaging.

MATERIALS AND METHODS

A total of 40 periapical lesions undergoing apical surgery were selected between December 2016 and November 2017. The participants were randomly divided into four study groups: control, MTA, PRF, and MTA+PRF. No interventions were made in the control group except root-end resection. Routine radiographs were taken in the 3rd, 6th, and 12th months. The volume and density of periapical lesions at the 1-year follow-up were compared with the pre-op values using the MIMICS software program. Primary healing of the periapical tissues was evaluated, and the outcomes were noted.

RESULTS

Post-op volume values were significantly decreased, and density values were significantly increased according to the pre-op measurements. In the post-op volume evaluation between the groups, significant differences were observed in the MTA and MTA+PRF groups compared with the control group (p < 0.005). However, no substantial significance was noted between the control and PRF groups. There were no significant differences in post-op density calculations between all groups.

CONCLUSION AND CLINICAL RELEVANCE

High success rates were achieved using MTA in periapical lesions in endodontic microsurgery. The application of PRF to the surgical cavity may not necessarily improve outcomes. Further studies are needed with long-term follow-up.
