About this study

Official title: Mandibular Molar Protraction Assisted by Temporary Anchorage Device and Piezoelectric Corticotomy

This study was conducted to compare the rate of second molar protraction, level of Interleukin1-β in gingival crevicular fluid, periodontal health (gingival index, plaque index, and periodontal pocket depth) and root resorption in patients treated by molar protraction with piezocision performed early at the time of protraction (Group 1), piezocision performed 3 months after molar protraction (Group 2), and no piezocision molar protraction (Group 3).

Read the detailed description

Detailed Description: Thirty-five subjects who presented with bilaterally extracted mandibular first molar were selected to participate in the study. The subjects were subdivided into one of 3 groups as follows: group 1 consisted of 20 subjects /20 molars where piezocision was performed immediately before molar protraction; group 2 consisted of 20 subjects/ 20 molars where molar protraction was carried on after 3 months of molar protraction with no piezocision; group 3 consisted of 20 subjects (40 molars) where protraction was carried out with no piezocision.

After reaching 0.019X0.025" SS arch wire, NiTi coil spring was used for space closure (protraction force was 150g) attached from the lower second molar hook to the head of the mini-screw. Piezocision was performed by making 2 vertical incisions mesial and distal to the extraction space. Piezotome was inserted in the incisions previously made and bone cuts were done with a length up to mucogingival line and depth of 3 mm. Gingival crevicular fluid (GCF) sample was obtained from the mesiogingival side of the lower second permanent molar with use of Periopaper. GCF sample was repeated 1 day, 1 week and 4 weeks after molar protraction with piezocision or with no piezocision. Periodontal parameters were measured and lower molar root resorption was assessed using Perapical radiographs.

What is being measured

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

  1. Rate of molar protraction

    Measured in mm/month from dental casts

    Measured: 1 year

  2. Changes in the level of of Interleukin1-β

    Detected in Gingival crevicular fluid (GCF). The periopaper was placed for 60 seconds in the mesiogingival sulcus of the lower second permanent molar and was transferred to an Eppendorf tube containing phosphate buffered saline.

    Measured: 4 weeks

Secondary outcomes (2)
  1. Periodontal parameters (Plaque, gingival health, periodontal pocket depth, alveolar bone height)

    Plaque and gingival health are measured using plaque index and gingival index. pocket depth and alveolar height are measured in mm.

    Measured: 1 year

  2. Lower molar root resorption

    Length of lower second molar roots in mm

    Measured: 1 year

Model description
Split mouth design where piezocision will be performed at the time of molar protraction on the right or left side of the bilateral first molar extraction subjects and 3 months of molar protraction on the other side. A third group of subjects will act as a control where molar protraction will be done with no piezocision. \- Comparison between the 3 groups of subjects; Early piezocision, late piezocision and no piezocision molar protraction groups.

Questions about this trial

What is this clinical trial studying?

A study testing Piezocision in people with Orthodontic Appliance, run by Jordan University of Science and Technology.

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 4 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 8 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

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?

Rate of molar protraction (time frame: 1 year). 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?
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 8 Apr 2020.
