Correct answer: D — Concrescence
Concrescence is the fusion of the roots of two adjacent teeth through cementum only (no dentin union). It may be developmental or acquired (due to chronic inflammation or crowding). It is most commonly found in the maxillary molar region. Clinical significance: it may complicate extraction, as removal of one tooth may inadvertently extract the adjacent fused tooth. Preoperative radiographic assessment is essential.
