RESUMO
A rare case of aplasia of the mandibular condyle is presented along with the tomographic findings. A 31-year-old Caucasian woman presented with a main complaint of facial asymmetry. No family history or any trauma was found. A CT study was performed and the sagittal CT view demonstrated a complete absence of the left condyle. This case of unknown aetiology was thoroughly examined and, based on clinical findings, we suggest that it could be of developmental origin.

The detection of osteomas in the maxillofacial region may be the initial clinical finding in Gardner's syndrome (GS). The most common location of osteomas is in the skull, but the lesion can also occur in the jaws. We present a case of a 47 year old male patient with GS who was referred for radiological evaluation. Extraoral examination revealed an epidermoid cyst and the patient had a history of intestinal polyps. A panoramic radiograph demonstrated numerous osteomas and diffuse sclerosis of the mandible, and compound odontomas with impacted teeth. CT scan allowed the localization and extension of the osteomas, and showed other sites in the maxillofacial region as well. CT images also revealed a different behaviour of osteoma, invading the mandibular canal.

The authors, considering the radiographic complementary survey importance in Operative Dentistry, has made an analysis on the three main radiologic technics (Bite-Wing and Bisecting Angle and Paralleling Technic), in an attempt to compare the per cent magnification grade of the carious lesion radiographic image, by measurements taken at the tooth sections, and over the patient's radiographs, to contribute with a more accurate diagnosis performed by the dentist.
