Evaluation of Bone Regeneration After Apical Surgery Using Advanced Platelet-rich Fibrin: Utilization of Ultrasound for the Assessment of Periapical Lesions (EBRAAPUU)

December 13, 2024 updated by: Aleksandra Karkle, Riga Stradins University
The study examines the impact of advanced platelet-rich fibrin (A-PRF) on bone regeneration in apical surgery compared to standard methods. It highlights the effectiveness of ultrasound as a diagnostic tool for assessing periapical lesions. Eligible participants were adults with specific periapical lesions following root canal treatment failures. Exclusions included patients outside specific criteria, like those with advanced periodontal disease or undergoing orthodontic treatment. Participants were randomized into two groups: one receiving A-PRF to enhance bone regeneration and a control group without it. Both groups underwent apical surgery under magnification, with different postoperative protocols. The study involved radiological and ultrasonographic evaluations of lesion size and bone healing at baseline, 6 months, and 12 months, alongside blood analyses for Vitamin D and cholesterol level to assess their potential impact on healing.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  2. Patients after root canal treatment/retreatment
  3. Patients with or without the sinus tract
  4. Patients with root perforations
  5. Patients with clinical cases deemed unsuitable for non-surgical endodontic intervention
  6. Patients with traumatic lesions clearly indicated for endodontic apical surgery.

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: Control group (Without A-PRF)
During the surgery procedure A-PRF application is not intended.
Procedure: Apical surgery without using A-PRF
Participants will undergo an apical surgery procedure without using A-PRF. Patients will undergo comprehensive evaluation before the surgery and at follow-ups using clinical, radiological, and ultrasonographic techniques.
Experimental: Test group ( With A-PRF)
During the surgery procedure A-PRF application is intended.
Procedure: Apical surgery procedure using A-PRF
Participants will undergo an apical surgery procedure using A-PRF. Before the surgery and at follow-ups, patients will undergo comprehensive evaluation using clinical, radiological, and ultrasonographic techniques.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Volumetric bone volume healing assessment
Time Frame: Baseline, 6 and 12 month
Volumetric analysis of CBCT images will segment the defect in axial, sagittal, and coronal views. Bone volume will be measured in cubic millimeters (mm³) at pre-operative, 6-month, and 12-month follow-ups and compared between each other. Where 0 is - no periapical lesion/periapical lesion healed.
Baseline, 6 and 12 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Asessment of Ultrasound diagnostic accuracy for periapical lesion measurment
Time Frame: Baseline

During the baseline assessment, the dimensions of periapical lesions will be measured in millimeters and using the classification:

Category 1: no discernible periapical lesion was identified; Category 2: a periapical lesion was possibly present, however, the distinction was equivocal; Category 3: a periapical lesion was definitively observed. not unequivocal; Category 3: a periapical lesion was definitively observed. These measurements will then be analyzed in relation to images obtained through periapical radiography as well as those from cone beam computed tomography (CBCT). This comparison aims to evaluate the accuracy and reliability of different imaging techniques in assessing the size of periapical lesions.
