About this study

Official title: Effect of Dental Pulp Stem Cells and L-PRF Placed Into the Extraction Sockets of Impacted Mandibular Third Molars on the Periodontal Status of Adjacent Second Molars: a Split Mouth Randomised Controlled Clinical Trial

The purpose of this study is to compare the clinical and radiographic effectiveness of Leukocyte-Platelet Rich Fibrin (L-PRF) and L-PRF combined with dental pulp stem cell (DPSC) application to the extraction socket of mandibular third molars.

Read the detailed description

Patients aged between 18 and 30 years, seeking for bilateral impacted LM3 extraction surgeries and meeting eligibility criteria were included to the study. At baseline right and left impacted third molars (LM3s) were randomly assigned to one of the treatment group (L-PRF and L-PRF + DPSC). Baseline and 6th month clinical and radiographic measurements were compared.

Being tested
L-PRF + DPSC, L-PRF

What participants receive

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

  • L-PRF + DPSCProcedure or surgery

    Also called Leukocyte platelet rich fibrin plus dental pulp stem cells

    After surgical removal of impacted mandibular third molars, extraction sockets were filled with L-PRF membranes + DPSCs.

  • L-PRFProcedure or surgery

    Also called Leukocyte platelet rich fibrin

    After surgical removal of impacted contralateral mandibular third molars, each extraction sockets were only filled with L-PRF membranes.

What is being measured

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

  1. Probing pocket Depth (PPD)

    Probing pocket Depth (PPD) is the distance between gingival margin and bottom of the periodontal pocket in mm.

    Measured: 6 months

  2. Clinical attachment level (CAL)

    Clinical attachment level (CAL) is the distance between cemento-enamel junction and bottom of the periodontal pocket in mm.

    Measured: 6 months

Secondary outcomes (4)
  1. Radiographic vertical distance

    The cementoenamel junction (CEJ) and the most coronal point of the alveolar bone were identified (AC) on the mesial and distal of lower second molars on digital panoramic radiographs. The vertical ruler on each digital image was used to calibrate the image and to convert measurements from pixels to millimeters with ImageJ. The vertical distance (VD) between cemento-enamel junction and alveolar crest of the lower second molar was than measured with "straight line" tool of the software. In order to calculate the real distance; ertical distance was divided to the magnification factor for panoramic image (1.2).

    Measured: 6 months

  2. Relative bone density (rBD)

    For every extraction socket, a region of interest (ROI) is created for the socket region and one for the surrounding bone using the "Freehand Selection" tool of ImageJ software on panoramic radiographs. Mean grey values were recorded for each group and relative bone density (rBD) was calculated.

    Measured: 6 months

  3. Post-operative pain as assessed by visual analogue scale (VAS)

    Self-reported pain measured in a 100 mm visual analogue scale (VAS) in which (0) denoted "no pain" and 100 meant "severe pain" was recorded at the end of the surgery and 7 days after extraction.

    Measured: 7 days

  4. Assessment of analgesic usage

    The patients were asked to note the amount of analgesics within the post-operative 7 days.

    Measured: 7 days

Model description
Prospective within person randomised split-mouth study. Left and right surgical sites for each participant were randomized using an online generated list to determine test and positive control LM3. (http://www.randomization.com). LM2s and LM3 extraction sockets were divided into two groups: a test group (extraction sockets filled with L-PRF membranes + DPSCs) and a control group (extraction sockets filled with L-PRF membranes).

Questions about this trial

What is this clinical trial studying?

A study testing L-PRF + DPSC and L-PRF in people with Stem Cell and Third Molar, run by Baskent University at 1 site in Turkey (Türkiye).

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 2 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 24 Nov 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 Turkey (Türkiye). 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?

Probing pocket Depth (PPD) (time frame: 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04641533, which also lists 1 linked publication.

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 24 Nov 2020.
