The purpose of this course is to provide practical ‘hands-on’ information to students and clinicians for successful intraoral imaging with digital sensors. In addition, this course will briefly review the basics of intraoral imaging, but most importantly will go beyond those basics by highlighting common difficulties with sensors and providing solutions to help the dental professional produce high-quality diagnostic images. Numerous photographs and radiographic images are embedded in the text to enhance the mastery of the material.

There are numerous textbooks that thoroughly teach intraoral technique, it is anticipated that the learner will have a working knowledge as they begin this course, which will include basic imaging in discussions of modifications of techniques. The clinician will learn to assess the instrument system setup before pressing the exposure button with a critical evaluation of the horizontal and vertical angulations as dictated by the rod-and-ring alignment system used. There are multiple textbook resources available for intraoral technique instruction.1, 2 There are also many short videos available on electronic media, but ‘buyer beware’, as all videos are not accurate or complete.

Learning Objectives

Upon completion of this course, the dental professional should be able to:

  • Learn a method to determine the active area on a digital sensor.
  • Understand what variables are involved when imaging, and their effects.
  • Understand and assess proper vertical and horizontal angulation of the x-ray beam, by critiquing the aiming rod and ring’s position prior to exposure.
  • Understand when modifications of the sensor’s position in the mouth and PID position are necessary to create diagnostic images and learn to apply these modifications.
  • Understand the effects of altering sensor position and x-ray beam position.
  • Understand intraoral techniques for implant procedures.


  • P&G is providing these resource materials to dental professionals. We do not own this content nor are we responsible for any material herein.
  • Participants must always be aware of the hazards of using limited knowledge in integrating new techniques or procedures into their practice.  Only sound evidence-based dentistry should be used in patient therapy.
