RESUMO
Glandular Odontogenic Cyst (GOC) is a rare developmental cyst of the jaws. The histological features of GOC strongly suggest an origin from the remains of dental lamina. Radiographically, GOC presents as well-defined radiolucencies with uni- or multilocular appearance. A case of GOC in a 54-year-old black female is presented here. Clinical, histological and imaging features were evaluated. Due to the high tendency of recurrence and the aggressive potential of GOC, careful clinical and radiological evaluation must be carried out. CT scans are recommended because they provide accurate information about locularity of the lesion, cortical integrity, expansion of the lesion and involvement of the contiguous soft tissue.

OBJECTIVE: The purpose of this research was to provide further evidence to demonstrate the precision and accuracy of maxillofacial linear and angular measurements obtained by cone-beam computed tomography (CBCT) images. STUDY DESIGN: The study population consisted of 15 dry human skulls that were submitted to CBCT, and 3-dimensional (3D) images were generated. Linear and angular measurements based on conventional craniometric anatomical landmarks, and were identified in 3D-CBCT images by 2 radiologists twice each independently. Subsequently, physical measurements were made by a third examiner using a digital caliper and a digital goniometer. RESULTS: The results demonstrated no statistically significant difference between inter- and intra-examiner analysis. Regarding accuracy test, no statistically significant differences were found of the comparison between the physical and CBCT-based linear and angular measurements for both examiners (P = .968 and .915, P = .844 and .700, respectively). CONCLUSIONS: 3D-CBCT images can be used to obtain dimensionally accurate linear and angular measurements from bony maxillofacial structures and landmarks.
