Not Applicable
Recruiting
Conditions
Gingival Recession, Generalized
Interventions
Device: Local application of a HA gel for the treatment of MAGRs with mCAF technique and XCM
Procedure: Treatment of MAGRs with mCAF technique and XCM
Registration Number
NCT05370456
Lead Sponsor
University of Turin, Italy
Brief Summary

The primary aim of this study is to evaluate whether the effect of HA in combination with XCM for the treatment of MAGRs with a multiple coronally advanced flap technique (mCAF) achieves better results than the XCM with mCAF alone in terms of recession reduction (primary outcome) and other secondary root coverage outcomes (e.g. complete root coverage, mean root coverage). Moreover, this study aims to compare secondary clinical variables (e.g. keratinized tissue width (KTW) changes, probing pocket depth (PPD) changes, volumetric gain (VG), etc.), also with a digital approach, the patient-reported outcome measures (PROMs e.g. pain, swelling, bleeding) and lastly the expression of molecular mediators of tissue healing/regeneration. The hypothesis of this study is that at 6 months and 1 year follow-up the mCAF with XCM+HA is superior to the mCAF with only XCM in terms of recessions reduction and secondary clinical variables, including PROMs.
