MCCCD Official Course Competencies
1. Operate and maintain imaging equipment. (I) 2. Demonstrate infection control procedures while exposing and developing radiographs. (II) 3. Demonstrate radiation protection measures for the patient and operator. (III) 4. Select appropriate types and sizes of radiographic image receptor holders. (IV) 5. Expose, process, and mount intraoral images using the paralleling, bisecting, and modified techniques on various dentitions of mannequins. (V, VII-VIII) 6. Expose, process, and evaluate extraoral images. (VI-VII, IX) 7. Evaluate intraoral radiographs by identifying technique and processing errors and explain measures for corrections. (IX) 8. Identify the anatomical landmarks of the dentition, maxilla, and mandible on radiographs. (X) 9. Identify restorations, atypical, and pathological conditions on radiographs. (XI)
MCCCD Official Course Competencies must be coordinated with the content outline so that each major point in the outline serves one or more competencies. MCCCD faculty retains authority in determining the pedagogical approach, methodology, content sequencing, and assessment metrics for student work. Please see individual course syllabi for additional information, including specific course requirements.
