What is being measured

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

  1. Wound healing area

    Wound size will be assessed at Baseline after obtaining the graft, and 3, 7, 14, 21, and 42 days after surgery via direct measurement with a Periodontal Probe UNC 15 (Hu-Friedy, United States), length and height of the wound will be measured and recorded to the nearest millimeter

    Measured: Baseline

  2. Wound healing area

    Wound size will be assessed at Baseline after obtaining the graft, and 3, 7, 14, 21, and 42 days after surgery via direct measurement with a Periodontal Probe UNC 15 (Hu-Friedy, United States), length and height of the wound will be measured and recorded to the nearest millimeter

    Measured: 3 days after surgery

  3. Wound healing area

    Wound size will be assessed at Baseline after obtaining the graft, and 3, 7, 14, 21, and 42 days after surgery via direct measurement with a Periodontal Probe UNC 15 (Hu-Friedy, United States), length and height of the wound will be measured and recorded to the nearest millimeter

    Measured: 7 days after surgery

  4. Wound healing area

    Wound size will be assessed at Baseline after obtaining the graft, and 3, 7, 14, 21, and 42 days after surgery via direct measurement with a Periodontal Probe UNC 15 (Hu-Friedy, United States), length and height of the wound will be measured and recorded to the nearest millimeter

    Measured: 14 days after surgery

  5. Wound healing area

    Wound size will be assessed at Baseline after obtaining the graft, and 3, 7, 14, 21, and 42 days after surgery via direct measurement with a Periodontal Probe UNC 15 (Hu-Friedy, United States), length and height of the wound will be measured and recorded to the nearest millimeter

    Measured: 21 days after surgery

  6. Wound healing area

    Wound size will be assessed at Baseline after obtaining the graft, and 3, 7, 14, 21, and 42 days after surgery via direct measurement with a Periodontal Probe UNC 15 (Hu-Friedy, United States), length and height of the wound will be measured and recorded to the nearest millimeter

    Measured: 42 days after surgery

Secondary outcomes (6)
  1. Pain assessment

    Pain will be assessed via Visual Analog Scale (VAS) at Baseline, 3, 7, 14, 21, and 42 days after surgery. A line of 10 cm will be used in which at the left end of the line will have a verbal anchor stating "No pain" and on the other end the verbal anchor of "The most intense pain that I ever felt". The subjects will place a mark on the line and the distance from the beginning of the line up to the mark will be measured and recorded.

    Measured: Baseline

  2. Pain assessment

    Pain will be assessed via Visual Analog Scale (VAS) at Baseline, 3, 7, 14, 21, and 42 days after surgery. A line of 10 cm will be used in which at the left end of the line will have a verbal anchor stating "No pain" and on the other end the verbal anchor of "The most intense pain that I ever felt". The subjects will place a mark on the line and the distance from the beginning of the line up to the mark will be measured and recorded.

    Measured: 3 days after surgery

  3. Pain assessment

    Pain will be assessed via Visual Analog Scale (VAS) at Baseline, 3, 7, 14, 21, and 42 days after surgery. A line of 10 cm will be used in which at the left end of the line will have a verbal anchor stating "No pain" and on the other end the verbal anchor of "The most intense pain that I ever felt". The subjects will place a mark on the line and the distance from the beginning of the line up to the mark will be measured and recorded.

    Measured: 7 days after surgery

  4. Pain assessment

    Pain will be assessed via Visual Analog Scale (VAS) at Baseline, 3, 7, 14, 21, and 42 days after surgery. A line of 10 cm will be used in which at the left end of the line will have a verbal anchor stating "No pain" and on the other end the verbal anchor of "The most intense pain that I ever felt". The subjects will place a mark on the line and the distance from the beginning of the line up to the mark will be measured and recorded.

    Measured: 14 days after surgery

  5. Pain assessment

    Pain will be assessed via Visual Analog Scale (VAS) at Baseline, 3, 7, 14, 21, and 42 days after surgery. A line of 10 cm will be used in which at the left end of the line will have a verbal anchor stating "No pain" and on the other end the verbal anchor of "The most intense pain that I ever felt". The subjects will place a mark on the line and the distance from the beginning of the line up to the mark will be measured and recorded.

    Measured: 21 days after surgery

  6. Pain assessment

    Pain will be assessed via Visual Analog Scale (VAS) at Baseline, 3, 7, 14, 21, and 42 days after surgery. A line of 10 cm will be used in which at the left end of the line will have a verbal anchor stating "No pain" and on the other end the verbal anchor of "The most intense pain that I ever felt". The subjects will place a mark on the line and the distance from the beginning of the line up to the mark will be measured and recorded.

    Measured: 42 days after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Hyaluronic acid in people with Palatal Wound, run by Colgate Palmolive at 1 site in Brazil.

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 7 inclusion and 8 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 25 Nov 2025. 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 Brazil. 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?

Wound healing area (time frame: Baseline). 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?
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 25 Nov 2025.
