Brief Summary

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

The aim of the present study is to evaluate the clinical, aesthetic and patient-centered parameters of connective tissue graft associated or not with partial resin composite (RC) for the treatment of gingival recession with NCCL, performed before the surgical procedure.

Detailed Description

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

This was a prospective, parallel and controlled clinical trial.

\- Group CTG (control n = 20) - patients who received connective tissue graft to treat gingival recession associated with non-carious cervical lesion. Group CTG+RC (test n = 20) - patients who received connective tissue graft plus partial resin composite restoration to treat gingival recession associated with non-carious cervical lesion.

The surgeries, as well as all postoperative follow-up, were performed at the dental clinic of Institute of Science and Technology (ICT), State University of São Paulo (UNESP). For those recessions allocated to CTG group, two horizontal incisions were made at right angles to the adjacent interdental papillae, without interfering with the gingival margins of neighboring teeth. Two oblique vertical incisions were extended beyond the mucogingival junction, and a trapezoidal mucoperiosteal flap was raised up to the mucogingival junction. After this point, a split-thickness flap was extended apically, releasing the tension and favoring coronal positioning of the flap.The exposed root surface was gently scaled and planed until it became smooth in the CTG group. Afterwards, a thin and small connective tissue graft was removed from the palatal site and sutured over the root surface. Then, the flap was coronally positioned and sutured to completely cover the graft. For those recessions allocated to CTG+RC group, firstly a sterile rubber dam was placed to isolate the operative field and the coronal zone of the non-carious cervical lesion restoration was performed with a nanocomposite resin, following the manufacturer's instructions. The apical margin of the restoration was place 1 millimeter apically to the cemento-enamel junction estimation. In the following session the CTG+RC received the surgical procedure as described above where a thin and small connective tissue graft was removed from the palatal site and sutured over the root/restoration surface. Then, the flap was coronally positioned and sutured to completely cover the graft.

Clinical parameters were assessed at baseline and 3 and 6 months post-operatively.

Study Groups

Connective tissue graft (CTG)

After local anesthesia, the surgical procedure performed was the trapezoidal-type of Coronally advanced flap (CAF). After the flap was raised, the exposed root surface was gently scaled and planed until it became smooth. Afterward, a thin and small connective tissue graft that was sutured over the root surface. Then, the flap was coronally positioned and sutured to completely cover the graft.

CTG plus resin composite restoration

After local anesthesia, a sterile rubber dam was placed to isolate the operative field and the coronal zone of the non-carious cervical lesion restoration was performed with a nanocomposite resin, following the manufacturer's instructions. The apical margin of the restoration was place 1 millimeter beyond to the cemento-enamel junction estimation. In the next session, the surgical procedure performed was the trapezoidal-type of CAF. After the trapezoidal-type of CAF flap was raised, a thin and small connective tissue graft that was sutured over the restoration surface. Then, the flap was coronally positioned and sutured to completely cover the graft.
