Crown Dilaceration
A clinic case
Dias, Liliana Sofia / Bastos-Aires, Diana / Couto, Maria Rosa / Correia, Inês / Pereira-Lopes, Otília
Crown dilaceration of permanent teeth occurs due to the non-axial displacement of the already formed hard tissue portion of the developing crown at an angle to their longitudinal axis due to trauma to the primary predecessor. (1,2,3) The prevalence of crown dilaceration constitutes 3% of total injuries in developing teeth and is usually because of intrusion or avulsion of primary predecessors. (1,2) Crown dilacerations with palatal angulation of the crown occur most commonly in maxillary incisors, whereas labial angulation is more common in mandibular incisors .(1,2,3)
The final diagnosis is made after a full clinical and radiographic exam and a careful report of medical history by the dentist. (3)
