objectives: precise radiographic assessment of the nasopalatine canal is required to prevent implant failure. the purpose of the current study was to determine the three dimensional (3d) morphology, as well as the dimensions of the nasopalatine canal using cone beam computed tomography (cbct). materials and methods: in this descriptive cross-sectional study, maxillary cbct images from 300 patie...

conclusions: despite its known shortcomings, like every other diagnostic tool, panoramic radiography can contribute to the early detection of maxillary/mandibular lesions that in turn enable the dentist to devise an appropriate treatment plan. results: cysts were mostly more common in men despite the equal propensity of both genders to benign tumors. in contrast, women showed a higher frequency...

odontogenic tumors are derived from epithelial, ectomesenchymal and/or mesenchymal elements that are or have been a part of the tooth-forming apparatus. of all the odontogenic tumors, calcifying epithelial odontogenic tumor accounts for 1% of the cases. approximately 200 cases have been reported to date. there is no sex predilection, with a 2:1 predilection for the mandible, mostly in the premo...

A 76-year-old female presented at University hospital of Crete with a large painless mass (d<10 cm) of the left maxilla. The cytologic diagnosis in FNAB smears was of a diffuse large B-cell lymphoma of the maxilla that was confirmed histologically. The fine needle aspiration cytology (FNAC) in conjunction with immunocytochemistry can distinguish between benign and malignant lymphoid infiltrates...

Measurement of an individual molar provides rich information for forensic personal identification. We propose a computer-based system for extracting an individual molar from dental panoramic radiographs. A molar is obtained by extracting the region-of-interest, separating the maxilla and mandible, and extracting the boundaries between teeth. The proposed system is almost fully automatic; all th...

Although ossifying fibroma (OF) is a slow growing neoplasm, some lesions may behave aggressively, reaching massive proportions that may demand special treatment. Synchronous presentation of this lesion in the maxilla and mandible is a rare occurrence. A case is presented of a 27-year-old woman who manifested synchronous OF lesions in the left maxilla and right mandible. The clinico-radiologic a...
