What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a treatment called Platelet-rich fibrin (PRF) to determine its effectiveness in healing after tooth extraction, especially compared to using only a collagen plug. The researchers aim to discover if PRF, along with a person's age, enhances healing and regeneration. Individuals needing a molar extraction due to cavities, gum disease, or a broken tooth, and who plan to receive an implant later, might be suitable candidates. As an unphased trial, this study provides a unique opportunity to contribute to scientific understanding and potentially benefit from innovative healing methods.

Will I have to stop taking my current medications?

The trial requires that you do not take certain medications that affect bone healing, like bisphosphonates, long-term NSAIDs, or steroids. If you are on these medications, you may need to stop them to participate.

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

Research has shown that platelet-rich fibrin (PRF) is generally safe for people. Studies have found that PRF can aid wound healing and support bone growth after tooth extraction. No major reports of negative effects have emerged from its use, making it a safe choice for tissue and bone healing. The treatment involves placing a PRF plug in the socket after tooth removal, which aids healing without major side effects. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about using platelet-rich fibrin (PRF) for socket preservation because it introduces a natural, regenerative approach to wound healing. Unlike the standard treatments that typically rely on synthetic materials like collagen plugs alone, PRF harnesses the body's own platelets to accelerate tissue repair and regeneration. This method not only enhances the healing process but may also reduce the risk of infection and improve overall outcomes for patients following tooth extractions.

What evidence suggests that PRF is effective for wound healing?

Research has shown that platelet-rich fibrin (PRF), which participants in this trial may receive, aids healing after dental procedures. In about two-thirds of studies, PRF significantly reduced pain in the initial days following tooth extraction. It also accelerated gum healing and improved surgical wound closure. PRF has protected the bone supporting teeth, proving useful for maintaining area health after tooth removal. By speeding up healing and reducing discomfort, PRF offers promising benefits for individuals undergoing dental surgeries. ^{1 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for individuals aged 20-80 needing tooth extractions due to caries, periodontal disease, or other reasons and interested in dental implants. Participants should have non-infected sockets with sufficient bone thickness and good oral hygiene. Those with compromised immune systems, active cancer treatments, severe infections, uncontrolled diabetes, or certain medication use are excluded.

Inclusion Criteria

I am between 20 and 80 years old.

I need a tooth (molar) removed due to decay, gum disease, breakage, or it can't be fixed.

I am considering getting a dental implant after tooth removal.

Exclusion Criteria

I have a condition that weakens my immune system.

I have a blood disorder.

I am currently undergoing chemotherapy or radiation therapy.

What Are the Treatments Tested in This Trial?

Interventions

• Socket Preservation

Trial Overview The study investigates the impact of Platelet-Rich Fibrin (PRF) on wound healing after tooth extraction (socket preservation), particularly how age influences the regenerative benefits of PRF during this process.

How Is the Trial Designed?

Group I: Platelet-rich fibrin group. Active Control 1 Intervention

Following extraction, a Platelet-rich fibrin plug will be placed in the extraction socket and covered with a collagen plug.

Group II: Collagen plug only Placebo Group 1 Intervention

Collagen plug only
