Treatment of Periodontal Intrabony Defects With Liquid Platelet-Rich Fibrin Mixed With Denaturated Albumin Gel (ALB_PRF)

The objective of study also is to assess radiographic linear defect depth, and radiographic defect bone density following the application of liquid Platelet-Rich Fibrin (PRF) mixed with denaturated Albumin gel (ALB-PRF) or with bone allograft in periodontal intrabony defects. Patients and methods: 28 patients will be selected from the outpatient clinic in the Oral Medicine and Periodontology Department, Faculty of Dentistry, Mansoura University according to Pre-operative CBCT that will be used to evaluate the bone destruction pattern. According to the techniques that used in the treatment of periodontal bony defect, the participants will be randomly divided into 4 equal groups: Group I: will include 7 patients, in which the intrabony periodontal defects will be treated with open flap debridement and demineralized freeze-dried bone allograft (DFDBA) and mixed with liquid (PRF). Group II: will include 7 patients, in which participants will be treated with open flap debridement and liquid (PRF) mixed with denatured albumin gel (ALB-PRF) will be injected in periodontal intrabony defects. Group III: will include 7 patients, in which participants will be treated with open flap debridement, DFDBA mixed with liquid (PRF) and collagen membrane. Group IV: will include 7 patients in which participants will be treated with open flap debridement, DFDBA mixed with liquid (PRF) and ALB-PRF membrane.
