title: Subcutaneous emphysema.
abstract: Swelling appeared in an eight-year-old girl after amalgam restoration. The swelling, subcutaneous emphysema, due to the presence of air in the connective tissue disappeared over a period of two days; no complications occurred. The clinical importance of subcutaneous emphysema is that the migration of air to the mediastinum can cause death. According to the literature, many dental and oral procedures can cause subcutaneous emphysema. Since it can cause many complications due to infection, prophylactic antibiotic therapy is necessary.
