About this trial
Current literature on platelet rich fibrin (PRF) use in apicoectomies, also known as endodontic microsurgery, is sparse. PRF use in oral surgery or periodontal surgery has been more thoroughly researched. Whether it is able to reduce post-op pain or if it improves success rate in endodontic microsurgery is not well known. It is also not well known if it will be able to increase the rate of healing. This study will evaluate the success of endodontic microsurgery with and without PRF.

Trial outcomes
Primary outcomes
Change in bone deposition using voxel-based imposition
From the CBCT images Invivo imaging software (Anatomage, San Jose, CA, USA) will be used to obtain measurements from voxel-based superimposition. The voxel-based imposition is automated by the software to match the voxel grayscale values from the two image volumes. Originally developed by Bazina et al. this analysis method has been demonstrated to show reliable and accurate data. The Linear measurements will be obtained on the cross-section view (sagittal, coronal, and axial) of the periapical lesion on CBCT-1 (6 months) and CBCT-2 (12 months) images.
Secondary outcomes
Healing outcome assessed using clinical and radiographic findings
Healing will be assessed by two, board-certified endodontists and a board-certified maxillofacial radiologist. If a consensus cannot be reached, an additional board-certified endodontist will assist in the determination. Healing assessment assisted with 2D imaging will be classified according to Friedmann. These will include healed, healing, or persistent disease. Each will be given a grade of 1-3, one being healed and 3 being persistent disease.
