DH 121 - Dental Radiography Laboratory I
Credit Hours: 1
This laboratory course provides practical application of knowledge gained in DH 120. Using training manikins, emphasis is placed on the paralleling technique of acquiring dental radiographic images using image receptor positioning devices such as XCP instruments and Stabe film holders. Image receptor/film processing methods, film mounting, basic interpretation and self-evaluation of technique and processing errors are practiced. Techniques will include digital methods using phosphor storage plates, direct sensor technology, film based imaging and use of the nomad hand-held x-ray unit. Digital panoramic imaging will be introduced. Radiation safety for patient and clinician will be stressed. Minimum passing grade is "C-."
Upon completion of this course, the student will be able to:
- recognize and operate equipment designed for safe use of ionizing radiation;
- identify parts of the dental x-ray unit and hand-held x-ray unit to include digital radiography components used to produce dental images;
- place, expose and process a complete set of intraoral radiographic images, utilizing a variety of image receptors and holding devices;
- arrange dental radiographic images using the ADA accepted method;
- produce a diagnostically acceptable panoramic image, demonstrating use of a digital Panorex unit;
- critique technique, processing errors and recognize artifacts, and select the appropriate corrective action;
- perform quality assurance tests and document results as it pertains to equipment, dental radiographic image handling, and processing; and
- demonstrate knowledge in the care and maintenance of dental x-ray equipment and digital radiograph components.
