Extended Reading:
◆ Radiographic examination
→ A detailed radiographic examination is essential to establish the extent of the injury to the supporting tis sues, the stage of root development, and the relation to the permanent successors.
→ Always consider minimizing the risk of radiation to the child. Several angles are recommended.
→ Select the appropriate radiographic examination: 90° horizontal angle with central beam through the tooth in question ; occlusal view; extra-oral lateral view of the tooth in question may reveal the relationship between the apex of the displaced tooth and the permanent tooth germ as well as the direction of dislocation, but is seldom indicated as it rarely adds extra in formation.
◆ Use of antibiotics
→ There is limited evidence for use of systemic antibiotics in the management of luxation injuries and no evidence that antibiotic coverage improves outcomes for root fractured teeth. Antibiotic use remains at the discretion of the clinician as TDI (Traumatic dental injury)'s are often accompanied by soft tissue and other associated injuries, which may require other surgical intervention. In addition, the patient's medical status may warrant antibiotic coverage.
