Treating Intrabony Defect With MINST VS MINST Extended PRF

This study evaluates a minimally invasive non-surgical technique (MINST) for treating periodontal intrabony defects, with or without the addition of Extended Platelet-Rich Fibrin (e-PRF). The goal is to determine which approach provides better bone regeneration and gum healing. Study Procedures Control Group: Local anesthesia by infiltration at the treatment site Instrumentation of the root surface up to the bottom of the periodontal pocket Efforts are made to minimize trauma to soft tissues and interdental papilla using subpapillary access Cleaning is performed using piezo-electric devices with delicate tips, avoiding aggressive root smoothing or gingival curettage 3-4× magnification loupes are used to improve precision Intervention Group: All the above procedures Followed by injection of e-PRF, a preparation derived from the patient's own blood Blood is collected in 4 mL tubes and centrifuged at 700 g for 8 minutes The platelet-poor plasma is heated to create an albumin gel The remaining buffy coat (rich in platelets and growth factors) is mixed with the cooled albumin gel to form Alb-PRF, which is applied to the defect

Alb-PRF as an Adjunct to Regenerative Periodontal Surgery

Periodontitis is characterized by the progressive destruction of tooth-supporting tissues and may lead to the formation of intrabony periodontal defects. Regenerative periodontal surgery aims to promote the reconstruction of the periodontal attachment apparatus and reduce residual defect dimensions. Albumin platelet-rich fibrin (Alb-PRF) is an autologous blood-derived biomaterial that combines an albumin-based matrix with platelet-rich fibrin components. This randomized controlled clinical trial will evaluate the clinical and radiographic effects of Alb-PRF as an adjunct to regenerative periodontal surgery in patients with periodontitis-associated intrabony defects. Twenty-four participants will be randomly allocated to two parallel treatment groups. Both groups will undergo regenerative periodontal surgery involving defect debridement, root surface conditioning with EDTA, and placement of an allogeneic bone graft. In the experimental group, Alb-PRF will additionally be applied to the intrabony defect. The primary outcome will be clinical attachment level gain at 6 months. Secondary outcomes will include probing depth, radiographic defect fill, early wound healing, postoperative pain, oral health-related quality of life, and adverse events. Participants will be followed for 9 months.

Sub-junctional Pinhole Technique

Pinhole Regenerative Therapy (PRT) following minimally invasive non-surgical periodontal therapy (MINST) in the treatment of intrabony defects associated with Stage III Grade B periodontitis. Eligible patients with 2- or 3-wall intrabony defects will be randomly allocated to the study groups. Clinical outcomes, including probing pocket depth (PPD) reduction and clinical attachment level (CAL) gain, together with radiographic bone defect fill assessed by periapical radiographs and CBCT, will be evaluated over a 6-month follow-up period to determine the effectiveness of the proposed minimally invasive regenerative approacا

Injectable Platelet-Rich Fibrin With Minimally Invasive Non-Surgical Technique in Treatment of Periodontal Intrabony Defects

This study aims to clinically and radiographically evaluate the adjunctive effect of injectable platelet-rich fibrin (i-PRF) used in combination with a minimally invasive non-surgical technique for the regenerative treatment of intrabony periodontal defects.
