NCT04513886

Brief Summary

This study evaluated the outcomes in the early healing of palatal wounds after harvesting a subepithelial connective tissue graft (SCTG) using the single incision technique with placement of a collagen haemostatic sponge (CHS) without suturing the palate. The primary outcome of this study was to evaluate the early wound healing index (EHI).

ACTIVE COMPARATOR

After harvesting a subepithelial connective tissue graft using the single incision technique collagen haemostatic sponge placement and subsequent compression with gauze soaked in saline for 5 minutes, a cross- mattress suture and interrupted single sutures were performed using nylon 5-0 when appropriate.

Procedure: Subepithelial connective tissue graft (SCTG) using the single incision technique, with and without suturing the palate

no Suture Group

EXPERIMENTAL

After harvesting a subepithelial connective tissue graft using the single incision technique, collagen haemostatic sponge placement and subsequent compression with gauze soaked in saline for 5 minutes no suture was performed.

Procedure: Subepithelial connective tissue graft (SCTG) using the single incision technique, with and without suturing the palate

Interventions

A SCTG was harvested using the single incision technique described by Hürzeler \& Weng. The palatal incisions were standardized to extend between the area between mesial of the canine and mesial of the first molar.In the Suture Group sites a cross- mattress suture and interrupted single sutures were performed using nylon 5-0 when appropriate. In the no Suture Group sites, no suture was performed. In both groups, a CHS was placed after removing the graft to achieve the haemostasis of the palate and subsequent compressed with gauze soaked in saline for 5 minutes.

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Subjects with an indication of mucogingival surgery for single gingival recession treatment that required harvesting a subepithelial connective tissue graft
  • Age \>18 years ≤ 60 years.
  • Periodontally and systemically healthy.
  • Palatal fibromucosa width ≥ 2mm evaluated with a North Carolina probe placed perpendicular to the hard palate, prior to surgery.

You may not qualify if:

  • Smoking.
  • Contraindications for periodontal surgery.
  • Subjects presenting coagulation disorders (history of Haemophilia, von Willebrand disease or anticoagulant therapy).
  • Subjects taking medications known to interfere with periodontal tissue health or healing.
  • Subjects that had been operated on the palate (connective tissue removed) previously from that same donor area.
