Student Learning Outcomes

  • On a full mouth survey of radiographs, the student will be able to identify one radiolucent and one radiopaque anatomical feature in each arch.
  • The student will be able to recognize a cone cut error for premolar and molar bitewing radiograph.

Description

Intraoral radiographic technique continued with evaluation of film quality, proficient parallelism with the XCP film holders, proper patient management, and a reduction in technique errors. Introduction to direct digital panoramic radiographs and indirect intraoral images using PSP plates. Further identification of radiolucent and radiopaque landmarks of the head and neck using the panoramic image. Intended for students in the Dental Assisting Program; enrollment is limited to students accepted in the program.

Course Objectives

The student will be able to:
A. recognize skull and dental anatomy on radiographic films
B. identify on clinical radiographs all diagnostically unusable films (errors)
C. identify a patient who benefits from panoramic radiography
D. understand the certification and licensing of a dental assistant earning a radiation safety certificate
E. identify who is the legal owner of radiographs
