Ameloblastoma after surgical removal of an impacted mandibular molar. A case report.

A case of an ameloblastoma diagnosed about 3 1/2 years after removal of an impacted mandibular 3rd molar is presented. The pre-operative radiographs, though poor in quality, showed an ill-defined radiolucency in relation to the tooth. This feature was not apparent to the examiners at the time of first presentation. Despite unfavourable working conditions in developing countries, a high level of suspicion should be maintained to avoid serious sequelae at a later stage.

Image accuracy of plain film radiography and computerized tomography in assessing morphological abnormality of impacted teeth.

This study compares the image accuracy of computerized tomography (CT) with that of plain film radiography (PFR) in analyzing the 3-dimensional shape of impacted teeth suspected of being malformed. Eighteen patients with 22 malformed teeth were studied by PFR and CT. Crown shape, root shape, crown/root relationship, and tooth inclination and structure were assessed by PFR and CT. CT was found to be superior to PFR in showing the multiplanar shape of tooth crown and root, crown/root relationship, and tooth inclination (P <.001). No difference was found in the representation of tooth structures. The findings demonstrate that CT imaging is useful to diagnose and plan treatment for patients with unerupted and malformed teeth.

The necessity to adequately visualize impacted maxillary third molars: report of three cases.

Three case reports illustrate the inability to detect the presence of the impacted maxillary third molars by conventional periapical radiography. In each case there was extensive cystic proliferation causing damage to the bony maxilla, antrum, and tooth-bearing areas. The pathological conditions were subsequently detected by further radiographic study, and surgically treated.
