DEN 174 Dental Radiology 2

Lecture Hours: 1
Lab Hours: 3
Credits: 2

Continues DEN 164. Allows students to take additional adult and pediatric (pedodontic) manikin films using low-dose technique. Students develop skills in patient management and improve radiographic techniques by completing at least one full mouth patient x-ray series. Includes information in taking pediatric images, images in edentulous areas, images taken while the patient is in a supine position, endodontic images, occlusal views, and extra-oral images. Students learn utilization of the panoramic x-ray unit, film duplicators, and automatic film processors. Students expose and evaluate all Images, and are eligible to take the State x-ray examination upon successful completion of DEN 164 and DEN 174.

Prerequisite: Third term standing in the Dental Assisting program.
