Background: Even though numerous biomaterials have been devised and employed for periodontal regeneration, it should be well understood that the root surface receptiveness to clot formation and maintenance during initial periodontal wound healing, decides the nature of the connective tissue attachment. So this study was carried out with the prime objective of assessing the initial wound healing events occurring in vivo after the application of citric acid on to the root surfaces during periodontal regenerative therapy.
Materials And Methods: Thirty-two human teeth were used for this in vitro study.
