Course Description:

Radiography Refresh will provide a comprehensive review of radiation biology, radiation protection, H.A.R.P and quality assurance documentation needed in a dental office.

This course will engage learners in radiographic interpretation for the dental hygienist, discuss the importance of a full mouth series during the dental hygiene diagnosis and throughout the process of care (ADPIE). Participants will also gain a thorough understanding of the importance of radiographs while determining a client’s AAP Grade when completing a periodontal assessment.

Radiography Refresh will assist learners in trouble-shooting common radiographic errors many clinicians may experience. These errors include; overlapping contacts, cone cut, film placement, distortion (elongation/foreshortening). Special client considerations will be discussed as well, such as maxillary torus and mandibular tori, edentulous clients, high/narrow palates, gag reflexes and children.

Learning Objectives:

Define and explain radiation injury, ionizing radiation, cumulative effects, as well as long-term vs. short term effects of radiation.
Discuss communication strategies with clients with regards to radiation in dentistry.
Discuss risks vs. benefits of dental images.
Examine the Healing Arts Radiation Protection Act (H.A.R.P) and the role of a Radiation Protection Officer.

Analyze various intra-oral and extra-oral radiographs.
Distinguish between normal and abnormal radiographic findings.
Formulate a RBL % calculation as per AAP classifications through case study examples.
Classify clients as Grade A, B or C based on radiographic bone loss (RBL).

Discuss common radiographic errors in dentistry and causes.
Discuss film placement techniques to help correct common radiographic errors.
Compare the pros and cons of the paralleling technique to the bisecting technique.
Explain correct angulations of the PID (horizontal and vertical angulations).
