Clinical Trial Summary

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.


Clinical Trial Description

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. ;
