Evaluation of Sticky Bone With or Without EDTA for Treatment of Gingival Recession

Evaluation of Sticky Bone With or Without EDTA Root Surface Biomodification for Treatment of Gingival Recession: Randomized Controlled Clinical Study

Gingival recession is a common clinical finding in periodontal disease which is frequently associated with esthetic concerns, root hypersensitivity, and root caries. Many surgical therapeutic approaches have been developed to predictably obtain root coverage of gingival recession defects. Injectable PRF (I-PRF) is the liquid form of PRF. I-PRF is a bioactive agent obtained by low-speed centrifugation, and it has the capacity to stimulate tissue regeneration. At high concentrations, PRF may stimulate the secretion of several growth factors and trigger fibroblast migration. I-PRF is generally used in regenerative treatments, with good outcomes. Ethylenediaminetetraaceti acid (EDTA) is a chelating agent that could enhance the attachment of connective tissue to the root surface by exposing collagen and, as a consequence, enhance root coverage. EDTA works at neutral pH, and this property has been reported to preserve adjacent tissue vitality. The present study will be carried out to evaluate the effect of sticky bone with or without EDTA root surface biomodification for treatment of gingival recession.
