About this study

Official title: The Role of Surgical Flap Design on the Healing of Intraosseous Defects Treated by Means Regenerative Therapy. Randomized Controlled Clinical Trial.

The aim of the present study was to evaluate the impact of surgical flap design on the healing of intrabony defects treated by means periodontal regeneration. Forty patients were enrolled and allocated random in two groups. Patients of test group received a minimally invasive surgical flap , while patients of control group received a conventional access flap. In both group the intrabony were treated by means the same periodontal regeneration procedure (i.e application of enamel matrix derivative). Periodontal parameters were recoded at baseline and after 12-months observation time.

Read the detailed description

This study was designed as multicenter randomized control clinical trial. The present trial was conduced according to CONSORT statement for improving the quality of reports of parallel-group randomized trials .

The intra-bony defects of subjects allocated in test group were treated with a combination of minimally invasive surgical technique (MIST) and enamel matrix derivative(EMD), while the intra-bony defects of control group were treated using a combination of conventional open flap debridement with papilla preservation (COFD+PP) and EMD.

Primary outcome

The primary outcome was based on Clinical attachment level gain( CAL gain)

Null hypothesis

Statistically significant different in terms of CAL gain will be recorded between test and control procedures.

Sample Size Calculation

The investigators are planning a study of a continuous response variable from independent control and experimental subjects with 1 control per experimental subject. In a previous study the response within each subject group was normally distributed with standard deviation 0,92. If the true difference in the experimental and control means is 0,97, we will need to study 20 experimental subjects and 20 control subjects to be able to reject the null hypothesis that the population means of the experimental and control groups are equal with probability (power) 0,8. The Type I error probability associated with this test of this null hypothesis is 0,05. Twenty-six patients were enrolled in the study and allocated in test or control group. In each patients 1 intra-bony defect was considered.

Randomization

The patients were randomly assigned to one of the two experimental procedures. The allocation was carried out using a commercially available computer software package. Treatment allocation was performed at time of surgery by opening an envelope containing the information test (i.e.EMD + MIST) or control (i.e.EMD + COFD+PP) procedure, respectively.

Inclusion Criteria

  • Patients suffering from chronic periodontitis;
  • Male and female ;

  • II and III wall Intra-bony defects with an intra-bony component range from 3 mm to 6 mm for both groups;
  • Intra-bony defect located only at one aspect ( mesial or distal)

Exclusion Criteria

  • Patients with systemic disease;
  • Prolonged antibiotic treatment or anti-inflammatory treatment within 4 weeks prior to surgery;

  • Furcations;
  • Third molars
  • Teeth with circumferencial defects

What participants receive

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

  • Minimally invasive surgical techniqueProcedure or surgery

    Also called Conventional open flap debridement with papilla preservation

    After local anesthesia , for the sites of test group , a minimally invasive surgical technique (MIST) will be performed. The defects associated inter-dental papilla will be surgically approached with a diagonal incision following the pattern of the simplified papilla preservation flap. Flap elevation was to the buccal and oral aspect in the interdental space, An enamel matrix derivative (EMD) was applied into the defect.f A primary closure of the interdental papillae will be achieved using a 5-0 monofilament non resorbable suturing material.

Questions about this trial

What is this clinical trial studying?

A study testing Minimally invasive surgical technique in people with Periodontal Pocket, run by Iorio Research and Dental Practice at 1 site in Italy.

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 6 inclusion and 9 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 9 Sep 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 Italy. 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 attachment level gain ( CAL gain) (time frame: At 12 months). 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 9 Sep 2020.
