Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this investigation, a prospective cohort study, several key outcomes will be assessed. First, we seek to determine whether restoring the cementoenamel junction (CEJ) in Class B GRs before root coverage therapy yields comparable clinical and volumetric outcomes to Class A GRs with detectable CEJ. In addition, the influence of the CEJ restoration on dentin sensitivity and aesthetic satisfaction of the patient will be investigated. To our knowledge, it will be the first clinical study to use Pini Prato et al.'s surface discrepancy classification as a decision-making tool to guide periodontal-restorative procedures.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Type A gingival recession defects

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

Group Type EXPERIMENTAL

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

Intervention Type PROCEDURE

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

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

Group Type EXPERIMENTAL

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

Intervention Type PROCEDURE

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.
