Efficacy of PRF and Xenograft in Treating Mandibular Molar Furcation Involvements

2026년 8월 12일 업데이트: Thanh Si Ho, University of Medicine and Pharmacy at Ho Chi Minh City

Efficacy of Platelet-Rich Fibrin Combined With Xenograft in the Treatment of Mandibular Molar Furcation Involvements

The purpose of this randomized controlled clinical trial is to compare the effectiveness of advanced platelet-rich fibrin (A-PRF+) combined with xenograft versus a collagen membrane combined with xenograft in the treatment of degree II furcation involvements in mandibular first molars. Adult patients with periodontitis will randomly receive either the A-PRF+ treatment or the collagen membrane treatment during periodontal flap surgery. The study will evaluate clinical periodontal healing, bone regeneration using 3D imaging (CBCT), patient comfort (pain levels and satisfaction), and changes in the TWEAK biomarker in gingival crevicular fluid over a 6-month period.

연구 개요

상세 설명

Furcation involvements in molars pose a significant challenge in periodontal therapy. This study aims to evaluate a regenerative approach using advanced platelet-rich fibrin (A-PRF+) to enhance clinical and radiographic outcomes. The study includes adult patients with periodontitis who have a degree II furcation involvement (Hamp 1975) on a mandibular molar, with a probing pocket depth of ≥ 5mm after initial non-surgical therapy.

Eligible patients will be randomly allocated to one of two surgical interventions:

Test Group: Open flap debridement followed by the application of A-PRF+ mixed with a xenograft (Cerabone), covered by an A-PRF+ membrane.

Control Group: Open flap debridement followed by the application of a xenograft (Cerabone) covered by a resorbable collagen membrane (Guided Tissue Regeneration).

Clinical parameters including Plaque Index (PlI), Gingival Index (GI), Probing Pocket Depth (PPD), Gingival Recession (GR), Vertical Clinical Attachment Level (VCAL), and Horizontal Clinical Attachment Level (HCAL) will be recorded at baseline and 6 months post-surgery using customized acrylic stents.

Radiological assessments using Cone Beam Computed Tomography (CBCT) will measure furcation volume, bone fill, and new bone gray level at baseline and 6 months. Patient-reported outcomes, including pain perception (VAS), painkiller consumption, and post-operative satisfaction (Likert scale), will be monitored during the first week. Additionally, Gingival Crevicular Fluid (GCF) samples will be collected to analyze the concentration of the TWEAK biomarker via ELISA at baseline, 1 month, and 3 months post-surgery.
