About this study

Official title: Clinical and Radiographic Evaluation of Guided Tissue Regeneration With Radiation-sterilized Allogenic Bone Grafts or Xenogenic Grafts for the Treatment of Intrabony Defects in Aggressive Periodontitis: A Randomized Clinical Trial

The treatment of intrabony defects in patients with aggressive periodontitis remains a challenging procedure and novel therapeutic strategies are sought. The purpose of this study is to compare the clinical and radiographic outcomes of using guided tissue regeneration (GTR) with radiation-sterilized allogenic bone grafts (material prepared in the Central Tissue Bank in Warsaw, Poland) versus guided tissue regeneration with xenogenic grafts (Bio-Oss®, Geistlich Biomaterials, Princeton, New Jersey, United States) in the treatment of localized intrabony defects in patients with aggressive periodontitis.

Being tested
GTR + radiation-sterilize allogenic bone graft, GTR + xenogenic graft

What participants receive

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

  • GTR + radiation-sterilize allogenic bone graftDevice

    Guided tissue regeneration of intrabony defects with collagen membrane (Bio-Gide® Perio, Geistlich Biomaterials) and radiation-sterilized allogenic bone graft from the Central Tissue Bank in Warsaw

  • GTR + xenogenic graftDevice

Study groups in NCT03340012
Study groupRoleWhat they receive
GTR + radiation-sterilize allogenic bone graft (TEST)ExperimentalThe surgical procedure will be performed in line with minimally invasive surgical technique by Cortellini and Tonetti (2007). The intrabony defects will be debrided and the roots will be planned. The required quantity of radiation-sterilized allogenic bone graft will be delivered into intrabony defects. Subsequently, a trimmed collagen membrane will be placed over graft. The flaps will be sutured with non-absorbable modified internal mattress sutures.

What is being measured

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

  1. Change in Clinical attachment level (CAL)

    CAL will be measured in millimeters on the study teeth at 6 locations as a distance from the cementoenamel junction to the bottom of the gingival sulcus. The average differences between 12 months and baseline measurements at the sites with the most advanced attachment loss at baseline will be compared.

    Measured: Baseline and 12 months after surgery

Questions about this trial

What is this clinical trial studying?

A study testing GTR + radiation-sterilize allogenic bone graft and GTR + xenogenic graft in people with Periodontitis, Aggressive, run by Medical University of Warsaw at 1 site in Poland.

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 5 inclusion and 7 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 13 Nov 2017. 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 Poland. 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?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Clinical attachment level (CAL) (time frame: Baseline and 12 months after surgery). 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 13 Nov 2017.
