One of the most common complications after dental trauma is pulp necrosis, which is often associated with apical periodontitis. The management of these teeth is challenging due to large root canals, open apices, and thin dentinal walls. 1
Long-term irritation leads to periapical lesions and cysts in the apical region. If left untreated, necrotic and infected pulp causes inflammatory lesions in the periapical tissues to grow over time, leading to structural changes in the bone. In some cases, root canal treatment may be required later during follow-up of injuries, due to subsequent pulp necrosis and infection of the root canal system. 2-3
