Root Conditioning with Citric Acid and Ethylenediaminetetraacetic Acid and their Effect on Fibrin Clot Adhesion to Dentin-A Scanning Electron Microscopic Study
Journal Title: Journal of Clinical and Diagnostic Research - Year 2017, Vol 11, Issue 8
Abstract
Introduction: Root biomodifiers are used to remove the smear layer formed on the roots as a result of mechanical debridement and also to expose collagen fibers making the root surfaces biologically acceptable. Further, the blood element linkage to demineralized roots and clot stabilization by collagen fibres are vital for the wound healing and success of periodontal surgery. Aim: The aim of this study was to evaluate and compare the distribution of fibrin network to dentin surfaces conditioned with citric acid and Ethylenediaminetetraacetic Acid (EDTA) using Scanning Electron Microscope (SEM). Materials and Methods: Thirty human dentin blocks (4 mm x 3 mm x 1 mm) were prepared and equally divided into three groups. The control Group A specimens were treated with Phosphate Buffered Saline (PBS). The study Group B and C specimens were treated with citric Acid and EDTA respectively. After conditioning, a drop of fresh human whole blood was placed on the dentin specimens and was allowed to clot. The specimens were then processed using standardized protocol for SEM. The dentin surfaces were then analysed for fibrin network linkage under SEM and scored according to the degree of fibrin linkage to the dentin surface. Statistical analysis was done using Kruskal Wallis test to compare the score values between the study groups. Pairwise comparison between the study groups was done using Mann Whitney U test with Bonferroni correction. Results: The fibrin network formed on the dentin network were analysed and scores were given. Kruskal Wallis test and Mann Whitney U test with Bonferroni correction were used for statistical analysis. It was found that most of the dentin specimens conditioned with citric acid and covered with human blood exhibited dense fibrin network compared to EDTA. However, statistical analysis showed that there were no significant differences found between the groups (p=0.35). Conclusion: Citric acid and EDTA has almost comparable effect in promoting the adhesion of fibrin network onto the dentin surface which may further enhance connective tissue attachment to the root surface.
