Apical Periodontal Cyst, Apical Periodontitis
Conditions
Brief summary
This study evaluates the effect of leucocyte and platelet rich fibrin Block (L-PRF Block) during endodontic microsurgery (EMS) on patient's post-operative comfort and periapical bone healing in large peri-apical lesions.
Detailed description
This study evaluates the effect of leucocyte and platelet rich fibrin Block (L-PRF Block) during endodontic microsurgery (EMS) on patient's post-operative comfort and periapical bone healing in large peri-apical lesions. The trial design is an open randomized controlled clinical trial with two groups. Half of the participants will receive EMS with L-PRF Block (experimental group), the other half without (control group).
Interventions
Surgical removal of 3 millimeters of the root-end, removal of the apical pathology, Root-end preparation and retrograde filling. The entire procedure is done under magnification.

Eligibility
Inclusion criteria
* Provision of Informed Consent * Patients from 18 years old * Patients in need of an EMS * EMS is the only option to cure the periapical lesion * A periapical lesion that has a diameter of 10mm or more in sagittal plane, frontal plane or axial plane when measured on CBCT
Exclusion criteria
* Unlikely to be able to comply with the study procedures, as judged by the investigator * Orthograde endodontic (re)treatment is indicated * Known or suspected current malignancy * History of chemotherapy within 5 years prior to study * History of radiation in the head and neck region * History of other metabolic bone diseases * History of bleeding disorders * HIV disease * Hepatitis B or C * Systemic disease (osteoporosis, diabetes…)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Amount of peri-apical bone healing | 1 year | Amount of periapical bone healing in time: measured with Cone Beam Computed Tomography (CBCT). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient related outcomes | 7 days | Pain assessed with a Visual Analogue Scale ranging from 0 to 10 each day during the first 7 days post-op. |
| Bone or scar tissue healing | 1 year | Bone or scar tissue healing: Volumetric analysis using Cone-Beam Computed Tomography. Pre-operative CBCT data will be matched with the post-op CBCT scans in order to assess the volumetric changes during 1 year. |
| Success & survival rate | 1 year | Success & survival rate |
| Dentinal defects | 1 year | Dentinal defects: in the apical root before and after resection. Potential cracks and fractures that occur during the follow-up period will be assessed on CBCT en reported. |
