RESUMO
A single lens reflex camera, a prosumer camera and a smartphone camera were compared for their ability to produce digital intraoral images. Standardized intraoral images produced by the three cameras were evaluated according to sharpness, depth of field, exposure, white balance and image composition. The digital SLR camera was significantly superior to the prosumer camera regarding sharpness and depth of field. The digital SLR camera and the prosumer camera were significantly better than the smartphone camera when considering white balance. There were no significant differences in anterior versus posterior intraoral images for any of the camera systems.

We describe the case of a 43-year-old man who was referred to our dental school"s acute care clinic with pain and swelling of presumed dental origin in the left maxillary quadrant. Radiographic examination revealed extensive dental decay and periodontal disease. On questioning, the patient admitted to paresthesia of recent onset. Paresthesia associated with pain or swelling of the jaws is an ominous sign that should alert the clinician to the possibility of an underlying aggressive neoplasm. In this case, biopsy of the lesion confirmed that the patient had a rare malignant tumour of maxillary sinus origin, a sinonasal undifferentiated carcinoma.
