Subcutaneous Emphysema of Periorbital and Canine Space Following Endodontic Treatment

Emphysema of the subcutaneous tissue is an uncommon complication of dental procedures. Certain dental surgical procedures, such as extraction of teeth using air-driven handpieces and endodontic procedures are more prone to cause subcutaneous emphysema. Subcutaneous emphysema is typically self-limiting and only in a few instances has an impact on the long-term health of the patient. Patients with subcutaneous emphysema experience pain, distress and inconvenience. This paper presents a case of subcutaneous emphysema of the right canine and periorbital space following endodontic treatment of the upper right front tooth.
