Evaluating and managing a suspected enamel-dentin fracture in a primary tooth hinges on preserving tooth structure and preventing pulpal or periapical infection. Begin with a careful clinical exam to determine the fracture line, whether dentin is exposed, any mobility, soft-tissue injury, and signs of infection such as swelling or drainage. In children, pulp vitality tests are less reliable, so focus on clinical symptoms (spontaneous or lingering pain, tenderness to percussion, fistula) and radiographs to assess fracture depth, pulpal status, and any signs of root resorption or periapical pathology.

If dentin is exposed but there are no signs of pulpal inflammation or infection, seal the dentin with a protective liner (for example, calcium hydroxide or glass ionomer) and restore the tooth to seal against bacteria and sensitivity. For extensive fractures, a protective restoration or a full-coverage option like a preformed stainless steel crown helps protect the tooth and maintain occlusal function until natural exfoliation.

Endodontic treatment or extraction becomes considerations only if there is irreversible pulpitis or necrosis, a nonrestorable fracture, or other signs indicating the tooth cannot be saved. Radiographs aid in diagnosis, but management should not be limited to imaging; addressing pulp health, sealing dentin, and restoring or protecting the tooth are essential steps to preserve the primary dentition.
