DDS 343- Oral and Maxillofacial Radiology

Course title: Oral & Maxillofacial Radiology II

Course No & Code: 342 MDS

Credit Hours: 4 h ( 1h lecture & 3h practicals)

Level: Third year

-------------------------------------------------------------------------------------------------------

This is the second course of oral radiology which is comprehensive course in radiographic interpretation and differential diagnosis of developmental, pathological lesions and fractures of the jaws and associated structures.

The course is covered by the lectures in the first half of the year and practical & tutorials in the second half.

The lectures in the first half will encourage the student to participate in tutorials of the second half.

Overall learning objectives:

By the end of this course students should be able to:

  1. Describe the advanced imaging modalities, their uses in the head and neck including CT, MRI, US and nuclear medicine.
  2. Know different types of infections and their clinical and radiographic features.
  3. Know different types of Odontogenic and non Odontogenic cysts and to describe the radiographic appearance of each one.
  4. Know the most common benign Odontogenic and non Odontogenic tumors. Know the most characteristic radiographic features of benign lesions.know the clinical and radiographic appearance of each one.
  5. Know different malignant lesions stressing on the clinical and radiographic features. Be able to request the advanced imaging to complete the differential diagnosis.
  6. Know different types of bone lesions that have jaw manifestations stressing on the clinical features and radiographic appearance.
  7. Identify and diagnose fractures of the jaws and facial bones, their clinical features and different imaging technique used for diagnosis.
  8. Know the systemic disease and some of syndromes that can be manifested in the jaws.
  9. Know TMJ anatomy, different radiographic technique used to examine TMJ.To know the radiographic appearance of the most common disorders affecting the TMJ.
  10. Know Maxillary sinus anatomy, different radiographic technique used to examine sinus.To know the radiographic appearance of the most common diseases affecting the maxillary sinus.
  11. Know salivary gland anatomy different radiographic technique used to examine salivary gland. To know the radiographic appearance of the most common diseases affecting them.
