The Influence of Citric Acid Bone Surface Etching and Bone Defect Fill on GCF BMP-2 Release Profile

Intrabony Periodontal Defect Clinical Trial

Official title:
The Influence of Citric Acid Bone Surface Etching and Bone Substitute Intra-osseous Defect Fill on Crevicular Fluid BMP-2 Release Profile (Randomized Clinical Trial)

Clinical Trial Summary

This study evaluates the effect of citric acid on bone surface of infrabony defects when used for 30 seconds at ph 1 and 50% concentration before the application of bovine derived xenograft to fill the defect, Bone Morphogenic protein 2 (BMP-2) marker was evaluated in 5 different days during the first month after surgery and clinical and radiographic parameters were reassessed after 6 months

Clinical Trial Description

Citric acid have been widely used to treat root surfaces of periodontally affected teeth in order to render it biologically suitable for fibroblast reattachment. however, systematic reviews showed no clinical significance when it was used as a root surface conditioner. Recently it was found in experimental studies that when citric acid was used on bone surface for a brief period, it increased bone formation and improved consolidation of grafted bone to bone bed. In this study infrabony defects were treated with citric acid PH 1 and 50% concentration for 30 seconds before washing it off and then application of bovine derived xenograft was done to fill the defect. BMP-2 marker was evaluated at days 1,3,7,14 and 30 by taking a sample using perio-paper from the gingival crevicular fluid (GCF) and clinical and radiographic parameters were taken after 6 months of follow-up ;
