NCT06438094

Brief Summary

The goal of this prospective cohort study is to evaluate the effect of non-carious cervical lesions (NCCLs) on the outcome of root coverage therapy. The main question it aims to answer is: In gingival recessions associated with NCCLs, characterized by an undetectable cemento-enamel junction (CEJ), reconstruction of the CEJ with a cervical composite restoration, prior to root coverage surgery by means of a coronally advanced flap combined with a connective tissue graft (CAF+CTG), provides similar clinical and patient-reported outcomes, as compared to the treatment of gingival recessions associated with NCCLs, characterized by a visible CEJ, with root coverage surgery only, by means of a CAF+CTG. In NCCLs where the CEJ is undetectable (B-type defect), the CEJ will be reconstructed before surgery with a cervical composite restoration mimicking the anatomic features of the contralateral, homologous tooth. CAF+CTG treatment will be performed in all cases. Participants will be assessed at 6 weeks, 3 months, and 6 months to evaluate clinical, volumetric, and patient-centred outcomes.

Study Arms (2)

Type A gingival recession defects

EXPERIMENTAL

Gingival recession defects that present with a visible CEJ. These defects will receive root coverage surgery only.

Procedure: Root coverage surgery by means of a coronally advanced flap combined with a connective tissue graft

Type B gingival recession defects

EXPERIMENTAL

Gingival recession defects that do not present a visible CEJ. A cervical composite restoration will be done prior to root coverage surgery.

Procedure: Reconstruction of the CEJ with a composite restoration followed by root coverage surgery by means of a coronally advanced flap combined with a connective tissue graft

Interventions

A root coverage surgery will be performed using Zucchelli et al.'s coronally advanced flap combined with a connective tissue graft from the palate.

Type A gingival recession defects

Reconstruction of the CEJ with a composite restoration will be performed in B+ and B- defects prior to root coverage surgery. A root coverage surgery will be performed using Zucchelli et al.'s coronally advanced flap combined with a connective tissue graft from the palate.

Type B gingival recession defects
