About this study
Official title: Endodontic Microsurgery With the Use of L-PRF Block: a Randomized Controlled Clinical Trial

Read the 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).
- Conditions
- Apical Periodontitis, Apical Periodontal Cyst
- Being tested
- Endodontic Microsurgery
- Medical subject headings
- Periapical Periodontitis, Radicular Cyst
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Endodontic MicrosurgeryProcedure or surgery
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.
| Study group | Role | What they receive |
|---|---|---|
| With L-PRF Block | Experimental | Not described Receives: Procedure: Endodontic Microsurgery |
| No L-PRF Block | Active comparator | Not described Receives: Procedure: Endodontic Microsurgery |
What is being measured
The primary outcome is the main question the study is designed to answer.
Amount of peri-apical bone healing
Amount of periapical bone healing in time: measured with Cone Beam Computed Tomography (CBCT).
Measured: 1 year
Secondary outcomes (6)
Patient related outcomes
Pain assessed with a Visual Analogue Scale ranging from 0 to 10 each day during the first 7 days post-op.
Measured: 7 days
Patient related outcomes
Pain assessed with a questionnaire asking about analgesics usage each day during 7 days post-op.
Measured: 7 days
Patient related outcomes
Discomfort assessed with a Visual Analogue Scale ranging from 1 to 5 each day during the first 7 days post-op.
Measured: 7 days
Bone or scar tissue healing
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.
Measured: 1 year
Success & survival rate
Success \& survival rate
Measured: 1 year
Dentinal defects
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.
Measured: 1 year

Questions about this trial
What is this clinical trial studying?
A study testing Endodontic Microsurgery in people with Apical Periodontitis and Apical Periodontal Cyst, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 15 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Nastaran Meschi, PhD (0032476313889 ext. +32, Nastaran.meschi@kuleuven.be), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Amount of peri-apical bone healing (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Sep 2023; AzTrials last refreshed its copy on 6 Nov 2026.
