Impacted tooth associated with dentigerous cyst and compound odontoma – case report

Resumo

The dentigerous cyst is a benign cyst associated with
the development of odontogenic epithelium that covers the crown of
impacted teeth. These are prevalent in the first three decades of life,
reaching more often Caucasian males. Odontomas are hamartomas
affecting the dental tissues, which can be divided into compound and
complex odontoma. Odontoma affects children and young adults of
both sexes, with a predilection for jaw bone. Case report: A 12-yearold boy attended the Pediatric Dentistry Clinic of Positivo University,
complaining of pain in right parasymphysis region. The panoramic
radiograph showed an impacted tooth (#43) located in base of the
jaw below the apex of the teeth #31 to #42, with increased follicle. A
radiopaque mass with small fragments of approximately 1 cm, located
at the apex of the teeth #83 and #84 was seen. The patient underwent
surgery under general anesthesia to remove the impacted tooth and
radiopaque injury. Histopathological analysis of the dental follicle was
compatible with dentigerous cyst and dental fragments were diagnosed
as compound odontoma. The postoperative was uneventful, four
months after the surgery the patient began orthodontic treatment for
traction of tooth #44. Conclusion: Both lesions, dentigerous cyst and
compound odontoma have favorable prognosis and low recurrence rate,
but must be removed to maintain the integrity of the stomatognathic
system. In this case was important the inter-relationship between
dental specialties for the treatment of the patient.
