Management and prognosis of teeth with trauma induced crown fractures and large periapical cyst like lesions following apical surgery with and without retrograde filling.

Crown fractures are common detrimental consequences of dental traumatic injuries. Early management of such cases is mandatory in order to prevent subsequent pathological changes that could further complicate the treatment. Pulp necrosis, chronic and cystic apical periodontitis can be the fate if these teeth are left untreated.
