Dental trauma, by definition, is always a result of an acute energy transmission directly or indirectly on to the tooth and surrounding tissues, which can lead to crown-root fracture, alveolar bone injury and injuries of soft tissues of the oral cavity. Children are prone to dental trauma, especially in the young permanent dentition, mostly because of excessive physical activity. Data from different epidemiological studies show that around 20% of all children until the age of 18 suffer from some kind of dental trauma in the permanent dentition. Crown fracture with pulp involvement is a severe dental injury with many possible complications immediately after injury and with delayed problems that appear years later. Normal function of the dental pulp is one of the most important providers for the physiological growth and development of the immature root. Also, a traumatised tooth with a vital pulp has a much better long-term prognosis than an undeveloped nonvital tooth. Pulpotomy after trauma will ensure favourable conditions that can preserve pulp vitality, dramatically increasing the prognosis for the injured tooth with a complicated crown fracture.
