Patient-reported Outcomes of Donor Site Healing Using Different Palatal Protection Techniques

OTHER

Visual Analog scale (VAS) questionnaire

A Visual Analog Scale (VAS) questionnaire is a type of self-report tool where respondents mark a point on a continuous line to indicate the intensity of a subjective experience, like pain, fatigue, or happiness, between two extreme anchor points (e.g., "no pain" at one end and "worst possible pain" at the other), allowing for a more nuanced response compared to a standard Likert scale; essentially, it measures the degree of a symptom along a visual continuum.

OTHER

Vacuum-formed retainer (VFR) technique

On the day of surgery, the stent will be positioned to cover the palate and the anterior and posterior teeth, including their occlusal and buccal surfaces bilaterally, to provide retention. Vacuum-formed retainers are a common clinical practice used after harvesting a palatal graft, in order to provide a mechanical barrier to reduce post-operative pain.

OTHER

3-D printed acrylic resin stent (3DS) technique

On the day of surgery, the previously made palatal stent (3DS) will be placed in position and stabilized by mechanical retention in the palate and palatal surface of the maxillary teeth, bilaterally.

OTHER

Flowable resin composite stent (FRC) technique

On the day of surgery, a layer of flowable composite will be added, covering all the wound dimensions, restricted to the wound (no extension to the adjacent teeth). Flowable composite has been shown to help reduce pain using the same principal of providing a mechanical barrier to protect the palatal wound from the oral cavity

OTHER

Photographs of the patient's palate

At the 14-day, 30-day and 3-month follow-up visits, photographs of the patient's palate (Canon EOS 60D DSLR, Canon, USA) will be taken for healing evaluation as well as intraoral scans (TRIOS 4, 3Shape) of the palatal wound for linear and volumetric changes analysis.

OTHER

Measuring graft dimensions

The graft dimensions will be measured with the use of a periodontal probe and recorded on the data collection form. The professional preference in regard to technique applied and the time spent by the surgeon to adjust the stent intraorally will also be recorded in the same form.

OTHER

Chairside Polymer Stent

The stent will be placed directly in the roof of the mouth. Instructions will be provided to the patient about how to remove, place and clean the stent. The patients will be instructed to wear the stent for the first 3 days and per their personal preference on the 4th day and after.

Evaluate postoperative pain level after autogenous gingival graft comparing 3 different palatal dressing designs

Time frame: Up to 2 weeks post-operatively

Evaluate postoperative pain level by documenting the number of pain pills taken during the initial two weeks of the healing process.

Evaluate swelling and bleeding perception after autogenous gingival graft comparing 3 different palatal dressing designs

Time frame: 2 weeks, 1 month and 3 months post-operative

Using a Visual Analog scale (VAS) questionnaire indicating the subject's perception of swelling and bleeding following the graft. The VAS is a type of self-report tool where subjects mark a point on a continuous line to indicate the intensity of a subjective experience between two extreme anchor points (e.g., "no pain" at one end and "worst possible pain" at the other), allowing for a more nuanced response compared to a standard Likert scale. Essentially, it measures the degree of a symptom along a visual continuum.

Evaluate the willingness to retreat by the subjects after autogenous gingival graft comparing 3 different palatal dressing designs

Time frame: 2 weeks, 1 month and 3 months post-operative

Using a Visual Analog scale (VAS) questionnaire indicating the subject's willingness to retreat following the graft. The VAS is a type of self-report tool where subjects mark a point on a continuous line to indicate the intensity of a subjective experience between two extreme anchor points (e.g., "no pain" at one end and "worst possible pain" at the other), allowing for a more nuanced response compared to a standard Likert scale. Essentially, it measures the degree of a symptom along a visual continuum.

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
