A patient in orthodontic treatment suffers a traumatic tooth fracture of tooth #8 (maxillary right central incisor). All of the following are appropriate management options EXCEPT one. Which is the EXCEPTION?

Correct answer: D. Perform definitive crown restoration during active orthodontic treatment

• A. Calcium hydroxide as an indirect pulp cap is an appropriate emergency/interim measure if deep dentin is exposed but the pulp is not directly involved.
• B. Bonding the fractured tooth fragment back with composite resin is a recognized conservative, reversible treatment option that can be performed during orthodontics.
• C. Temporary composite resin restoration during orthodontics, followed by definitive crown after treatment, is the ideal management sequence for significant fractures.
• D. CORRECT. Performing a DEFINITIVE crown restoration during active orthodontic treatment is NOT appropriate. Active orthodontic forces continuously change the tooth position, gingival level, and bone anatomy, which would compromise the fit and margins of a definitive crown. The standard approach is to stabilize the tooth with temporary restoration and perform definitive crown restoration AFTER orthodontic treatment is complete.
