Abstract :
Dens invaginatus is one of the most common anomalies of tooth structure. It is caused by
the invagination of the crown surface during odontogenesis that enters the pulp chamber
of the affected tooth. Depending on the complexity of invagination, the tooth might
present with pulp necrosis, open apex and a complicated root canal system. This case
report presents an Oehlers’ type 2 dens-invaginatus in a mandibular premolar with
chronic apical abscess. In most cases, dens invaginatus is removed during treatment.
However, in this case report, based on cone-beam computed tomography (CBCT)
evaluation, non-surgical treatment and maintenance of the invaginated segment was
chosen in order to prevent compromising the tooth structure and its susceptibility to
future root fracture. This is a new treatment approach and has not been performed in
previous reports. Calcium-enriched mixture (CEM) cement was used as an apical plug
followed by gutta-percha in warm vertical compaction for root canal obturation. The case
was followed up for 36 months after treatment. This report highlights the importance of
selecting the appropriate treatment approach based on CBCT evaluation.
