Root fractures of the permanent teeth belong to the most severe dental injuries. They usually result from a horizontal impact and the most common afflicted teeth are upper frontal teeth, less common the lower teeth. All tissues of the tooth are afflicted, in same cases an alveolar bone too. The authors evaluate a group of patients with root fracture who were treated at the Dentistry Department of the Faculty Hospital in Pilsen in the years 1995–2002.
