Objectives
To present a case report of CBCT findings in a large bone cyst in a 14-year old girl, which
healed after endodontic treatment.
Materials and methods
The material consisted of conventional radiographs and two CBCT examinations performed by
means of Galileos (Sirona, Germany) unit in a female aged 14 years.
Results:
An asymptomatic patient consulted orthodontist due to ectopic position of maxillary canines.
Panoramic radiograph revealed a large bone cyst affecting tooth 34, which was neither carietic,
nor restored. Temporary diagnosis of a solitary bone cyst was formed. CBCT exam revealed larger
dimensions of the lesion – from distal surface of left canine root to the apex of the mandibular
left second premolar. The lesion was well demarcated, penetrated between the roots, and
reached 5 mm from alveolar ridge. The patient was referred for endodontic treatment of teeth
33, 34 and 35, and scheduled for surgery after end of the conservative treatment. The surgery
was postponed due to low blood count and the patient missed next appointments. CBCT exam,
taken 10 months after scheduled surgery, showed signs of almost complete healing of the cyst.
Histopathology of the cyst was not verified, since once the biopsy is taken, the treatment is
considered no longer non-surgical.
Conclusions:
The presented case shows a potential of non-surgical management of bone cysts in young
patients. The more and more frequent evidence found in literature on positive response of
periapical inflammatory cysts to non-surgical treatment favors this diagnosis in the presented
case.
