Evaluation of the effect of EDTA on root coverage at free gingival graft procedure

Abstract

Background: The present study has been designed to compare the effect of root surface biomodification with EDTA for the treatment of buccal gingival recession with free gingival graft.
 Materials and methods: This randomized controlled parallel clinical trial, 34 patients of 40 existing tooth Miller Class I and Class II gingival recession were treated with free gingival graft (FGG). Forty teeth with recession were assigned randomly to receive the free gingival graft with or without the application of an EDTA gel. Pre-treatment (Day 0) and post-treatment 3. and 6. months gingival recession height(GRH), gingival recession width(GRW), probing depth (PD), clinical attachment level(CAL) and width of keratinized tissue WKT were measured.
 Results: In FGG+EDTA group statistically significant changes from baseline were found GRH decreased from 4.7±1.5 mm to 1.3±1.2 and WKT increased from 0.9 ± 0.9 mm to 5.5±1.8 mm. Also in FGG group, GRH decreased from 4.6±1.3 mm to 1.3±1.2 mm and WKT increased from 0.9 ± 0.7 mm to 5.4±1.5 mm. For FGG and FGG+EDTA, the average root coverage 74.14% and 69.26% was found.
 Conclusion: In the light of these data obtained with the root surface biomodification agent EDTA have no beneficial effect for root coverage. In the light of these data obtained with the root surface biomodification agent EDTA have no beneficial effect for root coverage.
