Pulp health and calcific healing of a complicated crown–root fracture with additional root fracture in a maxillary incisor: A case report

Figure 2 The apexification of tooth 11 and the prolonged splinting period provided the pulp with stable conditions for progressively healing the fracture lines in tooth 21. A: A periapical radiolucency indicating pulp necrosis and apical periodontitis of tooth 11 (white arrow) and healing of the fracture lines (yellow arrow); B: The root canal of tooth 11 was dressed with a calcium hydroxide-based paste for 1 month and the healing of the fracture lines (yellow arrow); C: The periapical radiolucency healed and a calcified barrier at the apex of tooth 11 (white arrow). The progressive healing of the fracture lines (yellow arrow) in tooth 21; D: The localized gingival overgrowth of tooth 21 (yellow arrows).
