Tomography

Conventional tomography is used in dentistry to demonstrate objects lying in a plane of interest distinct from their surrounding anatomic structures. Through technique parameters, which generate the controlled blurring of structures above and below the plane of interest, anatomic structures are visualized without the superimposition noted on other types of plain radiographs. In this article, the basic principles of tomography have been reviewed and the clinical applications for conventional tomography in dentistry have been described.
