About this study

Official title: Clinical, Mechanical, and Histological Properties of Absorbable and Nonabsorbable Suture Materials Used in Periodontal and Dental Implant Surgery.

A suture is a biomedical device that is made of natural or synthetic materials. Sutures are used to close tissue surfaces until wounds heal and regain their ability to withstand normal stresses. Although different suture materials are available for various dental procedures, clinicians commonly neglect to select sutures based on their mechanical properties and capabilities. Instead, clinicians rely on their clinical experience to determine which suture material will suffice for wound closure and healing. To our knowledge, there have been no published studies detailing the results of mechanical testing on sutures after clinical application. The aim of this study is to clinically, histologically, and mechanically assess the four common sutures used in periodontal and dental surgery, with the hopes of providing clinicians with a guide that will allow them to choose sutures based on the clinical, histological, mechanical properties that best fit the stress and strain applied to the wound.

What is being measured

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

  1. healing changes around each suture material

    To determinate the healing changes around each suture material using the Healing Index of Landry and colleagues (1988)

    Measured: 1 week, 2 weeks 1 month and 3 months after surgery.

  2. Tensile and mechanical properties of each suture material

    Evaluation of the tensile mechanical properties of each suture material using a Chatilloin TCD200 jig attachment, and tensile load will be applied to each suture at 0.05N/mm per min. Each suture will be stretched to failure and the maximum load will be recorded in Newtons (N).

    Measured: following 1 week of clinical application.

  3. Biofilm formation around each suture material

    To determinate the biofilm formation around each suture material using PCR

    Measured: following 1 week of clinical application.

Secondary outcomes (3)
  1. complications including erythema, edema, hematoma, infection, wound dehiscence, keloid or scar tissue

    To determinate the presence of complications including erythema, edema, hematoma, infection, wound dehiscence, keloid or scar tissue

    Measured: 1 week, 2 weeks, 1 month and 3 months after surgery.

  2. plaque adherence over sutures, number of sutures present and number of stable (untied) sutures

    To determinate the plaque adherence over sutures, number of sutures present and number of stable (untied) sutures

    • Plaque adherence over sutures. This will be classified as following: 0: no debris or plaque present;
    1. soft debris or plaque covering not more than one third of the sutures,
    2. soft debris or plaque covering more than one third of the exposed suture;
    3. soft debris of plaque covering more than two thirds of the exposed sutures.

    Measured: 1 week after surgery.

  3. subject satisfaction

    To determinate subject pain/satisfaction using a Visual Analogue Scale (VAS) at Visits 2 and 5. The VAS will be given to the subject in order to rate the satisfaction on a scale from 0 to 10, where 10 is the highest level of pain/satisfaction.

    Measured: 1 week and 3 months following surgery.

Questions about this trial

What is this clinical trial studying?

A study testing Polyglycolic Acid, Catgut and Polytetrafluoroethylene in people with Suture Adverse Reaction and Suture; Complications, Mechanical, run by Universidad Científica del Sur.

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 3 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 21 Jan 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?

Results are not available in the source record.

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

Contact Carmen Castro Ruiz, DDS (+51952392367, dra.castroruiz@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

healing changes around each suture material (time frame: 1 week, 2 weeks 1 month and 3 months after surgery.). 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 21 Jan 2020.
