About this study

Official title: Reconstruction of Deficient Interdental Papilla Using Allogenic Umbilical Cord-Mesenchymal Stem Cells vs. Physiological Saline: A Randomised Controlled Trial

The goal of this study is to assess the reconstruction of interdental papilla following the injection of UC-MSCs or physiological saline in patients with interdental papilla deficiency. Participants will be randomised into 2 groups (intervention vs placebo) to receive the treatment.

Read the detailed description

This is a two-arm parallel, prospective, single-center randomised clinical trial, which will be designed based on the guidelines from the Consolidated Standards of Reporting Trials (CONSORT) statement and will be registered in clinicaltrials.gov. Participants will be screened according to the inclusion and exclusion study criteria, and recruited from Orthodontic Postgraduate Clinic, Universiti Malaya.

Total sample size will be set at 20 interdental papilla after considering all the sample sizes calculated using different objectives, due to the cost effectiveness, the practicability, and consideration on the risk and complications.

This research is divided into 3 phases: pre-operative, operative, and post-operative phase.

Pre-operative includes full mouth scaling, baseline data collection (intra-oral scanning for soft tissue; cone beam computed tomography (CBCT) for hard tissue, basic periodontal examination). Then, the black triangle from upper or lower arch will be randomly assigned to two groups: the intervention (Stem cells) group, and the control (saline) group.

Operative phase involves injection either with the experimental or control solution. One injection will be given at each papilla set with the volume of 0.1mL with 2.0 x 10⁶ cells per syringe at every visit. A total of 3 injections will be given at the interval of 6 weeks, with a total of 6.0 x 10⁶ cells for each interdental papilla at the end of the 3 injections. Every injection starts with locally application of local anesthetic. For the control group, participants will be injected with 0.9% sodium chloride after locally application of local anesthetic.

Post-operatively, at 6, 12, 24 and 36 weeks, data will be collected for analysis. Intra-oral scanning of soft tissue will be done at every visits. CBCT for hard tissue will be done at 36 weeks. At every follow up, basic periodontal examination will be scored for periodontal health supervision. Data collected will be entered and analysed using SPSS 26.0. Images from the scans (soft tissue scans, hard tissue scans) will be superimposed and the difference between the 2 images will be calculated and analysed.

Umbilical cord-mesenchymal stem cellsExperimentalInjection of the UC-MSC into the interdental papilla using a standardised 1mL syringe will be done. 0.1mL (2millions cells) will be administered per black triangle. If there are three black triangles, only two black triangle will be treated, skipping the middle black triangle to avoid additive effect of the intervention

What is being measured

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

  1. Volumetric difference of the deficient interdental papilla pre- and post-intervention

    Intra-oral scanner will be used to scan the dentition and gingiva. Both pre- and post- intervention scans will be exported to Materialise 3-matics software to be superimposed and analyse for the volumetric difference

    Measured: 9 months

  2. Volumetric difference of the interdental bone between pre- and post-intervention

    Cone beam computed tomography (CBCT) will be taken before intervention and 9 months after intervention. The CBCT images will be exported to Materialise 3-matics software to be superimposed and volumetric difference would be analysed.

    Measured: 9 months

  3. Difference of bone density between pre-and post- intervention

    CBCT will be taken pre-intervention and 9 months after intervention. The CBCT images will be exported to Materialise 3-matics software. A range of "hu" will be selected as "old bone". Different in bone density from the range indicates new bone formation.

    Measured: 9 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Umbilical cord-mesenchymal stem cells in people with Gingival Recession, Localized, run by University of Malaya at 1 site in Malaysia.

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 11 inclusion and 12 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 1 May 2024. 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 Malaysia. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

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?

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?

Volumetric difference of the deficient interdental papilla pre- and post-intervention (time frame: 9 months). The study lists 3 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 1 May 2024.
