Which scenario most clearly justifies extraction of the central upper incisor?

• A. Root fracture related to dental crowding
• B. Dento-alveolar disharmony with crowding
• C. Central upper incisor impacted with enough space
• D. Class II/1 Angle malocclusion

Answer: (A)

When an anterior tooth has a poor prognosis because of a root fracture, extracting that tooth can lead to a simpler, more predictable treatment outcome in a crowded upper arch. A fractured central incisor with questionable pulpal and periodontal prognosis is at high risk of failure if preserved, and removing it eliminates an unreliable element while freeing space to align the remaining teeth. This approach also preserves facial aesthetics and supporting structures by allowing better restoration of the incisor region with the remaining teeth. In contrast, the other scenarios don’t mandate removing the central incisor. Dento-alveolar crowding can usually be resolved by moving or extracting premolars rather than a front tooth. An impacted central incisor with enough space is typically managed by eruption guidance or surgical exposure, not extraction, since preserving the incisor is a priority for aesthetics and function. Class II/1 malocclusion is addressed with premolar extractions or other mechanics, and removing the central incisor would create midline and esthetic problems without resolving the underlyingIssue.
