What is the purpose of this trial?

This trial tests two treatments to aid wound healing in the mouth after surgery. Researchers aim to determine if a special membrane, amnion-chorion, which contains growth factors that aid healing, is as effective as a common gauze called ActCel. They compare the treatments' effects on healing and the level of pain patients experience afterward. Individuals needing oral surgery between their molars and who have access to a smartphone might be suitable for this trial. As an unphased trial, this study offers a unique opportunity to contribute to medical research and potentially benefit from innovative treatments.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify whether you need to stop taking your current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that the amnion-chorion membrane (ACM) is generally safe for use in oral surgeries. One study found it effective in repairing cleft palates, as it helped close wounds well after surgery. Another study confirmed its safety when used on mouth wounds.

The amnion-chorion membrane aids in healing wounds, reducing swelling, and supporting tissue growth. These benefits make it a good choice for surgeries in the mouth and jaw area. So far, no major safety issues have been reported with using ACM in these situations.

The current study phase is "Not Applicable," indicating no new data about side effects in this trial yet. However, existing research strongly indicates its safety and effectiveness. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Amnion-Chorion Membrane (ACM) for palate wound healing because it harnesses the power of natural growth factors found in amnion and chorion tissues. Unlike traditional treatments like standard gauze or collagen dressings, ACM offers a biological approach that actively promotes healing by delivering these growth factors directly to the wound site. This innovative method has the potential to speed up recovery and improve overall healing outcomes, making it a promising alternative to existing options.

What evidence suggests that the Amnion-Chorion Membrane is effective for palate wound healing?

This trial will compare the use of the amnion-chorion membrane (ACM) with ActCel Cellulose Gauze for palate wound healing. Studies have shown that ACM aids wound healing by containing substances that promote cell growth and new blood vessel formation. In one study, ACM performed as well as traditional collagen dressings for healing areas after gum surgery. Another study found ACM safe and effective for closing wounds after cleft palate repairs. These findings suggest ACM could be a promising option for improving healing and reducing pain in palate surgeries. ^{2 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for adults aged 18-89 needing gum surgery in the mouth area from back molar to back molar, whether they have teeth, implants, or none.

They must also be able to follow up and own a smartphone.

What Are the Treatments Tested in This Trial?

Interventions

• ActCel Cellulose Gauze
• Amnion-Chorion Membrane

Trial Overview

The study compares two methods of healing after gum surgery: using an amnion-chorion membrane (ACM) versus ActCel Cellulose Gauze—a common bleeding control product. It aims to see if there's a difference in how the palate heals and how much pain patients feel with each treatment.

How Is the Trial Designed?

Group I: Use Amnio Chorion Membrane (ACM) with hemostatic agent Active Control 2 Interventions

ACM or amnion-only membranes have been used in oral surgical procedures primarily because they contain a host of growth factors that play a role in normal wound healing.

Group II: Use of ActCel Cellulose Gauze (Commercial Hemostatic Agent) Placebo Group 1 Intervention

Palatal wound dressing with hemostatic agent

Published Research Related to This Trial

Amnion/chorion membranes have been shown to significantly enhance wound healing in various conditions, including diabetic foot ulcers and difficult-to-heal fistulas, when used alongside standard treatments.

Clinical trials indicate that patients receiving amniotic membrane products experience higher rates of wound healing compared to those receiving standard care, highlighting their efficacy in wound management.

In a study involving 10 patients undergoing bilateral alveoloplasty, the use of dehydrated human amniotic/chorionic membrane (dHACM) significantly improved wound healing compared to standard suturing without dHACM.

Statistical analysis showed a significant difference in healing outcomes (P<0.05), indicating that dHACM may enhance recovery in surgical procedures by leveraging its anti-inflammatory and growth factor properties.

The amniotic membrane, derived from fetal membranes, contains amniotic epithelial cells that release biologically active factors promoting cell growth and healing, making it a promising material for wound dressings.

Despite its known benefits such as anti-inflammatory and scar-preventing properties, the specific molecular mechanisms behind these effects are not fully understood, highlighting the need for further research into amniotic membrane applications in wound care.

In a study of 117 patients treated with dehydrated human amnion/chorion membrane (dHACM) allografts over 2 years, 91.1% achieved complete healing of their nonhealing wounds, demonstrating the efficacy of this treatment.

dHACM was effective for various types of wounds, including diabetic foot ulcers and venous leg ulcers, with an average of 5.1 weekly applications needed for healing, indicating its potential as a versatile option in advanced wound care.

In a study involving 43 patients, the use of human amnion-chorion membranes for alveolar ridge preservation showed no significant difference in bone vitality or dimensions compared to collagen membranes, indicating both are effective options.

After an average healing period of 19.5 weeks, neither membrane type compromised ridge dimensions or bone vitality, suggesting that intentional exposure of the membranes does not negatively impact the healing process.
