Premolar Extraction Complication — NDEB AFK MCQ

Correct answer: D — Root fracture

Root fracture is the most common complication during extraction of maxillary premolars due to their thin, often bifurcated roots (especially the first premolar with divergent buccal and palatal roots). The thin roots are prone to fracture if excessive force is applied or if inadequate luxation is performed before forceps extraction. Slow, controlled buccal-palatal movements with appropriate forceps and adequate reflection of bone if needed reduce this risk. OAC is more common with maxillary molars.
