Department of Maxillofacial Surgery and Diagnostic Sciences
Office Phone No. 467-7443


This is a first year comprehensive course in post-graduate dental education. Therefore, the students still remember a good part of their undergraduate basic knowledge about radiation physics, biology, imaging and interpretation.

The main target during this course is to give the students the knowledge in radiology which render them good clinicians, competent in their specialties.

When this course is completed, the students should have good knowledge about the following:

- The importance of having good quality radiographs that enable them to establish a proper diagnosis, treatment planning and follow up of cases.

- Which types of radiographic images are indicated for each clinical case in order to obtain the maximum information with the minimal radiation exposure to the patient.

- How to establish a correct differential diagnosis for the most common maxillo-facial lesions.

- How to differentiate benign from malignant lesions in order to avoid the serious sequalae of malignancy.

- How far the recent modalidies in tissue imaging as computed tomography (CT), magnetic resonance imaging (MRI), ultrasonography (US) and scientegraphy could assist in establishing the proper diagnosis for maxillofacial lesions.

- How will be the future of dental radiography with the unlimited advancement of digital imaging in dentistry with its various capabilities in image processing, manipulation and transmission to remote areas for consultation and diagnostic support.


The course will be held in a lecture-seminar format of teaching. The total number of lectures / seminars should be 15 with the assessments included. One lecture/seminar will be given every week according to the following outline.


Two assessments will be held, one following the first eight lectures and one at the end of the course. Both exams will be in the form of multiple choice questions and short answers. In addition, some radiographs will be viewed in combination with historical and clinical findings pertinent to the case for identification or establishing a differential diagnosis. The time allowed for the first exam will be one hour and for the final exam will be two hours.

Midyear exam     20 degrees
Final exam              60 degrees
Writing assignment 20 degrees       


The students are required to prepare a writing assignment consisting of one subject pertinent to oral radiology or to their specialities. This assignment should be well carried out and evaluated considering the organization, sequence, figures, and references included.


Oral Radiology. Principles and Interpretation

1. Introduction & Upgrade I

The outline of the course will be explained to the students considering also the way of evaluation, requirements and additional subjects they would like to add to the outline. Also, their undergraduate knowledge will be up-dated regarding the importance of radiology, imaging principles, films and the dark room techniques.

2. Upgrade II

The student’s undergraduate knowledge will be updated regarding the radiation effects and safety, the answers of some questions for worried patients in addition to the general guidelines for prescribing radiographs.

3. Interpretation of Dental Caries

How to identify the presence of the different types of caries as well as their extent and description and what is false negative and false positive evaluation.

4. Interpretation of Periodontal Disease

How to identify the presence of periodontal disease considering the various types of involvements with their various severities and the most suitable imaging modalities including digital subtraction radiography.

5. Inflammatory Lesions of the Jaws

The student’s will be able to identify the presence of inflammatory lesions, their appearance and the best methods and techniques used to identify them.

6. Advanced Imaging Modalities CT, MRI, US and Scientegraphy

The recent imaging modalities in use now and which assist in the diagnosis of maxillofacial lesions. The use of them sometimes is essential to obtain some information difficult or sometimes impossible to obtain by conventional radiography.

7. Cyst of the Jaws

All cystic conditions which may occur in the maxillofacial region will be discussed, identified and a their differential diagnosis will be discussed.

8. Benign Tumors

Benign lesions which may occur in the maxillofacial region will be discussed, identified and a differential diagnosis will be discussed.

9. Malignant Tumors

Malignant diseases which may occur in the maxillofacial region will be discussed, identified and a differential diagnosis is discussed. The difference between benign and malignant disorders will be stressed in order to render the student capable for establishing an early diagnosis of malignancy to avoid its serious sequaele.

10. Systemic Disease Manifested in Bone

Systemic disorders may have manifestations in the maxillofacial region will be discussed, identified and a differential diagnosis is discussed. Moreover, the early dental signs and symptoms of some systemic diseases will be discussed to render the dentist capable for establishing an early diagnosis of the case.

11. TMJ Disorders and Imaging

The examination of the TMJ, the different imaging modalities and the most common disorders of the TMJ and how they are imaged and diagnosed will be discussed.
12. Digital Radiography

Digital radiography is the new frontier in dental radiology. It is probably the fastest growing area in our discipline. The image can be manipulated, stored, archived, retrieved, printed or transmitted to remote areas for consultation and diagnostic support. The subject will be discussed considering the principles, advantages, disadvantages and the possible future applications of digital radiography

13. Trauma to the Teeth

The identification of various types of trauma to the teeth as fracture, intrusion, extrusion or avulsion will be discussed with the best ways for their imaging.
