About this study

Official title: Surgical Extrusion for the Clinical Crown Lengthening: a 12-months Prospective Clinical Study

This is a prospective study in which surgical extrusion of single-rooted teeth is carried out by the same operator in 15 consecutive patients.

Main objective: to evaluate the soft tissue rebound of the teeth 1 year after the surgery.

Null hypothesis (H0): surgical extrusion is not a predictable treatment for the restoration of single rooted teeth.

What is being measured

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

  1. Soft tissue rebound

    mm

    Measured: 12 months after the surgical extrusion

  2. Tooth mobility (Miller classification)

    mm

    Measured: 12 months after the surgical extrusion

  3. Periapical lesion occurrence

    Assessed as the presence or not of a radiolucency at periapical radiograph (yes/no)

    Measured: 12 months after the surgical extrusion

  4. Patient's response to pain or discomfort at percussion test

    Patient's response measured by yes/no

    Measured: 12 months after the surgical extrusion

  5. Patient's response to pain or discomfort at palpation test

    Patient's response measured by yes/no

    Measured: 12 months after the surgical extrusion

  6. Root resorption occurrence

    Assessed as the presence or not of an inflammatory root resorption and a replacement root resorption at periapical radiograph

    Measured: 12 months after the surgical extrusion

Secondary outcomes (7)
  1. Periodontal probing

    mm

    Measured: 12 months after the surgical extrusion

  2. Gum bleeding on periodontal probing (yes/no)

    Visual

    Measured: 12 months after the surgical extrusion

  3. Tooth plaque quantity

    Measured visually according to Turesky plaque index, in which the best score is 0 (no plaque) and the worst score is 5 (plaque covering 2/3 or more the crown of the tooth).

    Measured: 12 months after the surgical extrusion

  4. Interproximal papillae height

    Measured visually according to Jemt's index, in which the best score is 3 (interproximal space completely occupied) and the worst score is 0 (absent interproximal papilla).

    Measured: 12 months after the surgical extrusion

  5. Marginal bone loss

    mm

    Measured: 12 months after the surgical extrusion

  6. Crown-root ratio

    mm

    Measured: 12 months after the surgical extrusion

  7. Patient's satisfaction

    Measured visually using a visual analogue scale, in which the best score is 0 (highest level of patient's satisfaction) and the worst score is 10 (lowest level of patient's satisfaction).

    Measured: 12 months after the surgical extrusion

Questions about this trial

What is this clinical trial studying?

A study testing Surgical extrusion in people with Tooth Decay, run by Universitat Internacional de Catalunya at 1 site in Spain.

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 3 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 17 Apr 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 Spain. 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?

Soft tissue rebound (time frame: 12 months after the surgical extrusion). The study lists 6 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 NCT04350853, which also lists 4 linked publications.

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 17 Apr 2020.
