Periodontal Diseases Clinical Trial
Official title:
The Use of Leucocyte Platelet Rich Fibrin (L- PRF) Covered Perforated Guided Tissue Membrane for Treatment of Periodontal Intrabony Defects (Randomized Clinical Trial)
This study is the first to investigate the effect of leucocyte platelet rich fibrin (L-PRF) combined with perforated membrane in order to treat infrabony defects and assess their combined effect in clinical attachment level gain and filling of base of the defect (BD). The main hypothesis was that if the L-PRF act as a chemoattracttant for a higher number of periosteal derived periodontal cells (PDPCs) and gingival mesenchymal stem cells (GMSCs) encouraging their passage through the membrane perforations.
A randomized (controlled) clinical trial which included forty sites with intrabony interproximal defects (2- or 3-wall) premolar/molar teeth assessed for clinical parameters. The four treatment modalities were randomly allocated by a predetermined computer generated randomization list (www.randomizer.org) into four equal groups; Group I (control group) open flap debridement (OFD): included intrabony defects treated by open flap debridement (OFD).Group II perforated membrane (PM): included intrabony defects treated by perforated membranes.Group III Leucocyte-platelet rich fibrin (L-PRF): included intrabony defects treated by leukocytes platelet rich fibrin (L-PRF). Group IV Leucocyte-platelet rich fibrin + perforated membrane (L-PRF + PM): included intrabony defects treated by Leucocyte platelet rich fibrin & perforated membranes. ;
