Localized gingival recession caused by a C-PAP mask: a case report.

This case report describes a localized gingival recession on the labial of tooth # 6 caused by the nasal mask of a C-PAP (Continuous Positive Air Pressure) machine. The patient was diagnosed with obstructive sleep apnea (OSA). Treatment consisted of night-time use of a C-PAP machine. The patient noticed sudden exposure of the root surface on no. 6 and sought evaluation by his family dentist. He was referred to a periodontist for evaluation. A subepithelial connective tissue graft was performed to repair the defect. A maxillary bite splint with a buccal and apical extension to protect the grafted area was constructed. The patient is able to wear the C-PAP mask and protective splint concurrently for successful treatment of his OSA and maintenance of the newly grafted connective tissue. We as dental practitioners can use this information to evaluate the etiology of gingival recession, especially those occurring in patients with OSA.
