Apical Periodontitis, Wound Heal
Conditions
Brief summary
A total of 40 periapical lesions from the 33 patient undergoing apical surgery were randomly selected from December 2016-November 2017. Patients were informed about the surgical procedure and signed a consent form. Groups were divided in to 4; as control, MTA (mineral trioxide aggregate), PRF (platelet rich fibrin) and MTA+PRF groups. Apical resection was performed in all groups. No other interventions were made to the control group. Routine radiographs were taken in the 1st. 3th and 6th months. In the (approximately) 12th month of the procedures computerized tomography scans were taken. Primary healing of the periapical tissues were evaluated and the outcomes were measured. Patients have still been under control for the long term outcomes of the study.
Detailed description
44 apically infected periapical lesions were decided to enroll to the study from December 2016-November 2017. However; a total of 40 periapical lesions undergoing apical surgery were recruited for the planned clinical trial in the end. The study was conducted under randomized controlled protocol. Patients were informed about the surgical procedures and signed a consent form. The anticipated outcomes, possible risks and benefits of the study as well as the alternative treatment options were explained to the patients. Groups were designed to have 10 patients in each and randomly divided into four as; control, MTA, PRF and MTA+PRF. Apical resection was performed in all groups. No other interventions were made to the control group. Routine radiographs were taken in the 1st. 3th and 6th months. In the 12th month of the procedures computerized tomography (CT) scans were taken. Primary healing of the periapical tissues were evaluated according to the volumes and the densities of the lesions. Outcomes were measured. Comparison between the initial and the last 3D CT scan volumes were made by medical image processing software (MIMICS, Belgium). Patients have still been under control for the long term outcomes of the study.
