Trial summary

This study is the first to investigate the effect of leucocyte platelet rich fibrin (L-PRF) combined with perforated membrane in order to treat infrabony defects and assess their combined effect in clinical attachment level gain and filling of base of the defect (BD). Read more about this study

  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Both genders aged from 18- 60 years.

About this study

Official title: The Use of Leucocyte Platelet Rich Fibrin (L- PRF) Covered Perforated Guided Tissue Membrane for Treatment of Periodontal Intrabony Defects (Randomized Clinical Trial)

This study is the first to investigate the effect of leucocyte platelet rich fibrin (L-PRF) combined with perforated membrane in order to treat infrabony defects and assess their combined effect in clinical attachment level gain and filling of base of the defect (BD). The main hypothesis was that if the L-PRF act as a chemoattracttant for a higher number of periosteal derived periodontal cells (PDPCs) and gingival mesenchymal stem cells (GMSCs) encouraging their passage through the membrane perforations.

Read the detailed description

A randomized (controlled) clinical trial which included forty sites with intrabony interproximal defects (2- or 3-wall) premolar/molar teeth assessed for clinical parameters. The four treatment modalities were randomly allocated by a predetermined computer generated randomization list (www.randomizer.org) into four equal groups; Group I (control group) open flap debridement (OFD): included intrabony defects treated by open flap debridement (OFD).Group II perforated membrane (PM): included intrabony defects treated by perforated membranes.Group III Leucocyte-platelet rich fibrin (L-PRF): included intrabony defects treated by leukocytes platelet rich fibrin (L-PRF). Group IV Leucocyte-platelet rich fibrin + perforated membrane (L-PRF + PM): included intrabony defects treated by Leucocyte platelet rich fibrin \& perforated membranes.

Questions about this trial

What is this clinical trial studying?

A study testing Open flap debridement, perforated membrane and leucocyte - platelet rich fibrin in people with Periodontal Diseases, run by Ain Shams University at 1 site in Egypt.

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 8 inclusion and 5 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: finished, as of the sponsor's last update on 8 Oct 2020. 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 Egypt. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

clinical attachement level gain (time frame: 6 month). 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 8 Oct 2020.
