Healing of Mandibular Third Molar Extraction Sockets Using Platelet Concentrates and Photobiomodulation

Poland122 participantsStarted 2020-01-02

Plain-language summary

Surgical removal of impacted mandibular third molars is a common procedure that may be associated with postoperative pain, swelling, limited mouth opening, and delayed bone healing. Various regenerative techniques are used to improve healing outcomes after tooth extraction. This study evaluated whether autologous platelet concentrates (advanced platelet-rich fibrin \[A-PRF+\] and concentrated growth factors \[CGF\]) and photobiomodulation using low-level laser therapy can improve healing after mandibular third molar extraction. Participants requiring surgical removal of a mandibular third molar were randomly assigned to one of six treatment groups. Depending on the group, patients received standard wound closure alone, photobiomodulation, placement of autologous platelet concentrates into the extraction socket, or a combination of platelet concentrates and photobiomodulation. Postoperative pain, swelling, mouth opening, and early wound healing were assessed during the first postoperative week. Bone regeneration within the extraction socket was evaluated using radiological imaging several months after surgery. All procedures used in this study are commonly applied in clinical practice and are considered safe. The results of this study may help identify the most effective approach to improve healing and reduce postoperative discomfort following mandibular third molar extraction.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
