|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, recognition of landmarks,and film errors. Bitewing radiography is emphasized. Introduction to digital panoramic radiographs and identification of radiolucent and radiopaque landmarks of the head and neck. IIntended for students in the dental assisting program.|
|Course Objectives - |
|Expected Outcomes and Dental Assisting Program Competencies |
The student will be able to:
Dental Assisting Program Competencies
Infection Control and Hazardous Waste Management
- utilizing a mannequin, expose, process and mount:
- a 6 film bitewing survey with no more than two retakes in approximately 45 minutes.
- a 20 film periapical full mouth survey with no more than 4 retakes in approximately one and one-half hours.
- maintain clinical patient records that record pertinent data and information required for procedures, film evaluation, and mailing.
- identify on clinical radiographs all diagnostically unusable films, indicate the specific fault or limitation, recognize and describe the improper procedure involved and suggest the procedural correction needed to improve the quality of the radiograph.
- analyze and use modified techniques to compensate for or overcome such unusual problems as:
- narrow arch
- shallow floor of the mouth
- describe or perform the following specialized procedures:
- occlusal radiograph for children
- panoramic radiograph
- list the advantages and disadvantages of the panoramic x-ray.
- from a panoramic survey, identify the major anatomic landmarks, soft tissue shadows and artifacts.
Ethical and Legal Principles:
- demonstrate the proper disposal of lead foil
- demonstrate the proper procedures for the prevention of cross contamination in the operatory and darkroom
- demonstrate the proper disinfection and sterilization procedures for film holders.
- demonstrate the proper disinfection procedures for the lead shield.
- describe the legal requirements for the operation of radiographic equipment
- list the legal ownership of radiographs
- demonstrate fidelity or act in the best interest of the patient by placing a lead shield on every patient prior to radiation exposure.
|Special Facilities and/or Equipment - |
- Gown, safety glasses, masks, and gloves.
- X-ray laboratory,darkroom facilities, mannequins, view boxes, film, PSP sensors and digital dental scanner.
|Course Content (Body of knowledge) - |
- Anatomical Landmarks (Lec)
- maxillary sinus
- median palatal suture
- zygomatic arch
- mandibular canal
- mental foramen
- genial tubercle
- Radiographic technique errors (Lec)
- backwards film
- blurred film
- under/over exposed film
- double exposure

- Ideal Patients or Needs for the Panoramic Radiograph (Lec)
- orthodontic patients
- trauma patients
- 3rd molar extractions
- conclusive maxillary and mandibular interpretations
|Methods of Evaluation - |
|Methods of evaluations are by written exams, slide quizzes and laboratory/clinical performance evaluations. Students are required to produce diagnostic dental x-rays. Dental film analysis and evaluation of technical placement will be completed on patients. |
