About this study

Official title: Scaling and Root Planning With Localized Delivery of Autogenous Growth Factors- Platelet Rich Fibrin (PRF): A Randomized Split-mouth Clinical Trial

The purpose of this research study is to find out about the effect of growth factors extracted from blood on improving healing of periodontal pockets (Gum pockets) after deep gum cleaning.

Read the detailed description

Blood has a lot of cells that help with healing and regeneration. These cells could be obtained by spinning blood in a centrifuge machine which allows the cells to separate at high spinning forces. After spinning, the blood will be separated into 3 different layers. The middle layer has the highest concentration of cells that help in healing and it is called the leukocyte platelet rich plasma (L-PRF).

The aim of this study is to use participant's own blood to retrieve (L-PRF) and place it in the diseased tissue around teeth, after the deep cleaning, to examine its effect in improving the healing and compare the results with gum pockets that haven't received L-PRF

In this study, participants will be asked to do the following things:

  1. Visit VCU Graduate Periodontics clinic 6 times for scheduled study visits after the initial periodontal exam.:
  • 1st appointment: A digital impression of upper and lower teeth using an intraoral scanner, a light source laser that will capture digital impressions of the teeth, will be taken. These digital impressions will be used to create removable resin stents that fit on top of the teeth which will help in obtaining accurate and reproducible clinical measurements. The stents will be used on almost all participant's visits to the graduate periodontics clinic for the duration of the study for data collection.
  • 2nd and 3rd appointment: The deep cleaning will be divided into 2 appointments which should be less than 2 weeks apart. During each appointment, one arch, either the upper or the lower arch, will be scaled and root planed. Local anesthesia will be used to anesthetize the participant before the cleaning. Ultrasonic cleaner and hand instruments will be used for the deep cleaning. After finishing the deep cleaning, 36 ml of participant's blood will be collected in 4 tubes through the antecubital vein. The tubes will be spun in an FDA approved spinning machine to obtain the liquid and membrane forms of the L-PRF. The L-PRF will then be inserted in the test sites on one side of the arch while the other side will not receive the L-PRF.
  • 4th appointment: Prophylaxis and plaque control 2 weeks after 2nd appointment.
  • 5th appointment: Evaluation of deep periodontal cleaning and data collection 4-5 weeks after the 2nd appointment
  • 6th appointment: Periodontal cleaning and data collection 3 months after 2nd appointment.
  1. Follow the oral hygiene instructions given

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • leukocyte platelet rich fibrin (L-PRF)Biological

    Participants blood will be spun to obtain L-PRF strips and liquid L-PRF. Pockets will receive insertion of small L-PRF strips followed by liquid L-PRF injections to fill the 5-8mm pockets of the test side.

  • Scaling and Root PlaningProcedure or surgery

    Scaling and root planing, which is the standard of care, will be performed on the control side using Cavitron and hand scalers on test and control sides under local anesthesia.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in probing depths (PD)

    PD will be measured from the gingival margin to pocket base using a participant specific fabricated removable resin stent with an assigned #15 UNC probe.

    Measured: Baseline to 6 months

  2. Change in clinical attachment level (CAL)

    CAL will be measured from cemento-enamel junction CEJ to the base of the pocket using the same stent as PD

    Measured: Baseline to 6 months

  3. Bleeding on probing (BOP)

    Bleeding on probing (BOP) will be recorded on an ordinal scale where sites that will bleed on probing will be given a score of 1 while sites that don't bleed will be given a score of 0.

    Measured: Baseline to 6 months

  4. Plaque index (PI)

    PI will be recorded using the Loe and Silness Index. Scores range from 0 - No plaque to 3 - Abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin.

    Measured: Baseline to 6 months

  5. Gingival index

    GI will be recorded using the Loe and Silness gingival index. Scores range from 0 - Normal gingiva to 3 - Severe inflammation - marked redness and edema, ulceration. Tendency toward spontaneous bleeding.

    Measured: Baseline to 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing leukocyte platelet rich fibrin (L-PRF) and Scaling and Root Planing in people with Periodontitis Chronic Generalized Severe and Periodontitis Chronic Generalized Moderate, run by Virginia Commonwealth University at 1 site in United States.

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 3 inclusion and 6 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: withdrawn, as of the sponsor's last update on 12 May 2022. 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 United States. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Change in probing depths (PD) (time frame: Baseline to 6 months). The study lists 5 primary outcomes in all. 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 12 May 2022.
