Subcutaneous emphysema related to air-powder tooth polishing: A report of three cases

Abstract

Subcutaneous emphysema is a rare complication of dental procedures and can occasionally give rise to potentially life-threatening complications. We describe 3 cases of subcutaneous emphysema diagnosed in the same dental clinic.

All cases occurred during tooth or implant cleaning using air polishing (KavoProphyflex^®) with a sodium bicarbonate powder (Air-N-Go Classic^®). The diagnosis was based on clinical findings and was confirmed radiologically. The cervical and facial regions were affected in all 3 cases, and spread to the mediastinum occurred in 1 case. All the episodes resolved within 3 to 5 days.

Tooth cleaning using air polishing combined with an abrasive powder is a risk factor for subcutaneous emphysema, especially when the powder and device are from different manufacturers. Radiological assessment must be performed to rule out involvement of deep tissue planes.
