Loss of pulp vitality in anterior permanent teeth of children was more commonly attributed to traumatic injuries than to any other causes. This high incidence of traumatic injuries is responsible for the greater frequency with which periapical pathological conditions develop in those teeth. If the dental pulp is damaged before development of the root length and closure of the apical foramen, normal root development is altered or halted completely (1). Such conditions present difficulty in root canal debridement and obturation because of the open apex. Such cases were traditionally treated by apexification procedures using calcium hydroxide.
