In a healed root fracture where the tooth remains stable and shows pulpal space hypercalcification, no further treatment is required because the pulp remains vital and the fracture has stabilized naturally. Initiating root canal therapy or surgical intervention is unnecessary unless clinical symptoms such as pain, mobility, or signs of infection develop. The hypercalcification indicates healing and reparative dentin formation, reflecting a favorable prognosis without intervention. Protecting the tooth with a crown is not mandatory if function and aesthetics are uncompromised. Monitoring is typically sufficient to ensure continued stability.
