title: Iatrogenic pneumomediastinum after endodontic therapy.
abstract: An unusual case of pneumomediastinum caused by subcutaneous emphysema occurring after the use of hydrogen peroxide solution during root canal treatment is described in a 30-year-old man. A thorough search of the available literature failed to reveal similar cases. A review of the literature, including pathogenesis, clinical and radiographic features, and management of this condition, is presented.
