Formation of a cyst-like area after a connective tissue graft for root coverage.

BACKGROUND: Many techniques have been developed to obtain root coverage. There have been few complications reported with these techniques. This case report chronicles the development of a cyst-like area after a connective tissue partial-thickness double pedicle graft was used to obtain root coverage.
METHODS: The root coverage procedure was performed as previously reported. Postoperatively, in the surgical area, the patient developed occasional swelling. It was possible to express a white material from the area. A biopsy was taken to determine the cause of the clinical findings.
RESULTS: Histological evaluation revealed the development of a cyst-like area.
CONCLUSION: The development of cysts does not seem to be a common event. However, this case report demonstrates that they are a possible complication of root coverage procedures.
