Erythropoietin Gel as an Adjunct to Xenograft in the Surgical Management of Intrabony Periodontal Defects

"1. Surgical sites will be anaesthetized using local anaesthesia.~2. Intrasulcular incision will be done in the periodontal pocket as close as possible to the tooth surface with the deepest point being the alveolar crest.~3. The incisions will be extended to the mesial papilla of the tooth before the defect and the distal papilla of the tooth after the defect.~4. Both buccal and lingual/palatal mucoperiosteal flaps will be raised using blunt dissection.~5. Mechanical debridement of the infected tissue from the intrabony defect and root debridement will be done using Gracey curettes.~ * In Group A (test group):~Particulate xenograft will be mixed with EPO gel and applied to fill the whole defect."

"* All surgeries will be performed by the same operator as follows:~ 1. Surgical sites will be anaesthetized using local anaesthesia.~ 2. Intrasulcular incision will be done in the periodontal pocket as close as possible to the tooth surface with the deepest point being the alveolar crest.~ 3. The incisions will be extended to the mesial papilla of the tooth before the defect and the distal papilla of the tooth after the defect.~ 4. Both buccal and lingual/palatal mucoperiosteal flaps will be raised using blunt dissection.~ 5. Mechanical debridement of the infected tissue from the intrabony defect and root debridement will be done using Gracey curettes.~* In Group B (control group):~Particulate xenograft will be applied to fill the whole defect."
