Blood injection may boost tooth infection healing

This study looked at whether injecting a substance made from a patient's own blood (injectable platelet-rich fibrin, or i-PRF) could help heal teeth with chronic infection at the root. Sixty adults with infected teeth received standard root canal treatment; half also got the i-PRF injection. Researchers measured two enzymes in fluid around the tooth to see if the injection changed healing activity. The goal was to understand if i-PRF might improve recovery, not to test a cure or symptom relief.
