Study: NCT06798116

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Experimental: open flap debridement and demineralized freeze-dried bone allograft and mixed with liquid (PRF
Description: Drawing 9 ml of blood into plastic test tubes without anticoagulants and other additives. This is followed by a centrifugation process according to the protocol for liquid PRF by using centrifuge under 2700rpm for 8 min.~The yellow top layer, formed upon centrifugation, consists of platelet-poor plasma that will be collect by a syringe in a volume of 2 ml, liquid PRF and buffy coat that will also be collected by a syringe in a volume of 4 ml. The Platelet-Poor plasma in the syringe will be transferred to a special machine that increases its temperature to 75°C for 10 minutes. ALB-PRF will be prepared by mixing the albumin gel with liquid concentrated growth factor including the buffy coat in a separate syringe by utilizing a female luer lock connector to obtain the injectable ALB-PRF in final ready form. in this group;, the defects will be treated with open flap debridement and DFDBA and mixed with liquid (PRF)

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: defects will be treated with open flap debridement and liquid (PRF) mixed with denatured albumin gel (ALB-PRF) will be injected in periodontal intrabony defects
