Compound odontoma associated with dentigerous cyst in the anterior mandible – case report

Resumo

The dentigerous cyst, also called a follicular cyst is
an odontogenic cyst that develops in association with crown of an
impacted tooth, predominantly in mandibular third molars of young
patients. The Odontoma is a ectomesenquimal tumor of unknown
origin that are more considered developmental malformations
(harmatomas) than benign neoplasms. Occasionally, the dentigerous
cyst is associated with odontoma. Objective: The article aims to
report a case of surgical treatment of dentigerous cyst associated
with compound odontoma and unerupted tooth in anterior region of
the mandible. Case report: A male patient, 17 years of age, without
systemic changes, was sent to the Center for Dental Specialties of
Horizonte, Ceará, Brazil, specialty of Oral and Maxillofacial Surgery,
for diagnosis and treatment of oral lesions visualized after periapical
radiographic examination to determine failed eruption of element
42. Observing the periapical radiograph it was possible to visualize
radiopaque lesion suggestive of a compound odontoma and a cystic
capsule in association with the element 42. A panoramic radiograph was requested and it was planned a surgical removal of odontoma
with curettage of bone cavity and removing the cystic capsule and
element 42. There were no significant postoperative complications,
the suture removal was performed 7 days after surgery where it was
possible to observe a good healing, no swelling and no paresthesia.
Conclusion: The treatment of choice is surgical excision of the lesions
with the tooth associated to the cyst, it should be performed with
proper planning, avoiding injury to vital structures and should not
be delayed in order to avoid possible occlusion sequelae.
