ClinConnect Summary
This clinical trial is studying a new way to help heal a specific dental problem called apicomarginal defects, which happen when there is damage around the tip of a tooth’s root and the surrounding bone. The researchers want to see how well a combination of bone graft material (allograft) and a special blood product (iPRF) works to heal these defects, both with and without using an additional protective layer called a collagen membrane. This could help improve healing after dental surgery in people who have had ongoing infections or issues despite previous root canal treatments.
People who might be eligible for this study are adults aged 18 and older who have a persistent infection at the tip of a tooth’s root that hasn’t healed properly, along with bone loss on the cheek side of the tooth. To join, patients should not have serious general health problems that would make surgery risky, and their tooth should have already had a root canal treatment that didn’t fully fix the problem. The study does not include those with fractured roots, widespread gum disease, or conditions like uncontrolled diabetes or pregnancy that could affect healing. If accepted, participants will undergo a surgical procedure where the researchers will use these materials to try to promote better healing, and they will be monitored to see how well the treatment works.
