[Dental CT: examination method, radiation dosage and anatomy].
Traditionally oral surgeons and dentists have evaluated the jaws using intraoral films and panoramic radiographs. The involvement of radiologists has been limited. In the past few years dedicated CT-software-programs developed to evaluate dental implant patients have provided a new look at the jaws. The complex anatomy is described and identified on human skulls and on axial, panoramic, and cross-sectional images. With this anatomic description Dental-CT-scans are used to demonstrate the anatomy of maxilla and the mandible. An overview of the technique of Dental-CT is provided, furthermore the radiation dose of different organs is explained. Suggestions to reduce these doses by simple modifications of the recommended protocols are given.
