Abstract

Objectives: CAF in combination with a connective tissue graft (CTG) is considered the technique of choice for treating gingival recessions (GRs). Among the many recognized factors that can affect the outcomes, the use of chemical agents has been proposed. The effect of EDTA, as a commonly used agent, remains controversial. Therefore, the aim of this review was to assess the efficacy of EDTA root conditioning when combined to CAF + CTG. Material and methods: A literature search was conducted to identify randomized clinical trials (RCTs) that performed CAF + CTG with and without EDTA for root coverage procedures. The following outcomes were assessed: recession reduction (Rec Red), complete root coverage (CRC), keratinized tissue gain (KT gain), clinical attachment level changes (CAL gain), and changes in pocket depth (PD changes). Results: Fourteen RCTs (575 GRs) were included and analyzed. Six articles were included in the EDTA group, with 8 in the non-EDTA group. Meta-analyses revealed statistically significant differences for the outcomes of Rec Red (3.68 mm versus 3.07 mm), CAL gain (4.15 mm versus 3.07 mm), and PD changes (− 0.44 mm versus 0.27 mm) in favor of the EDTA group, while outcomes of CRC (odds ratio of 1.15) and KT gain (1.98 mm versus 1.62 mm) were not significantly different. Conclusions: Limited evidence is available when evaluating the effectiveness of EDTA root conditioning with CAF + CTG. However, the adjunct application of EDTA with CAF + CTG appears to be beneficial. Clinical relevance: The adjunct application of EDTA may provide benefits when performing root coverage procedure via CAF + CTG.
