The calcifying epithelial odontogenic tumor (CEOT) is a rare entity and represents less than 1% of all odontogenic tumors. Dr. J J Pindborg (1958) first described four cases of this unusual lesion; subsequently Shafer et al coined the term Pindborg tumor. This lesion is a locally aggressive benign odontogenic neoplasm arising from epithelial tissue. It occurs most commonly in 4th-5th-6th decade of life and bears no gender predilection. A case of CEOT in a 50-year-old male arising in the left body region is described.

Osteonecrosis of the jaw is a severe bone disease that occurs as a result of reduced local blood supply. Bisphosphonate-associated osteonecrosis of the jaw usually occurs following dental procedures. We report clinical and radiological findings in a case of mandibular osteonecrosis associated with the use of bisphosphonate; the mandibular osteonecrosis was undiagnosed prior to cross-sectional imaging with computed tomography. The radiological correlation to the underlying pathological process and a correlative assessment of history, clinical, and imaging findings enabled the diagnosis. A discussion of differential diagnoses is provided to alert the oral radiologist to the presence of this condition in cases with typical imaging findings. The literature on indications for advanced imaging is reviewed to simplify the selection of the appropriate imaging modality for mandibular osteonecrosis.

Injury to the primary dentition is one of the common problems of childhood. Disturbances during crown development of the permanent teeth result in morphologic alterations. This case report highlights the role of 3-D imaging when conventional dental radiographs are not enough to answer our clinical questions regarding future eruptive disturbances. 3-D imaging can many times give us a definitive diagnosis and improve the treatment planning after early injuries in the deciduous dentition. The current status of multislice computed tomography (CT) and cone beam CT (CBCT) as diagnostic tools in pediatric dental population is also discussed briefly.
