Sample Licensing Examination for Dental Surgeons (Part B of the Exam)

For more information about the licensing process, see Dentistry in Israel.

Please note:  The illustrations accompanying the tasks are specific for the text of the exam. 
You are therefore required to return the illustrations together with your answers since without them
it will not be possible to check your answers.  The examination form, illustrations or part of them
may not be removed from the examination hall, or copied.

Here are 10 clinical situations you may encounter in your work.  Each is accompanied by clinical details
and a photographic or radiographic illustration. Read the clinical details carefully, examine the illustration
and answer the questions briefly.  Write legibly and relate only to the task required. The total mark for
these 10 tasks is 40% of the final mark of Part B.

Directions for the oral radiology tasks

Important: Before you start to answer the question, pay attention to the following points:

a. When relating to the radiograph, you are to diagnose findings in all the tissues of the
tooth and in the jaw bone adjacent to that tooth.

b. In your answer, specify exactly and clearly the region or the location where you diagnose
the lesion (e.g. the mesial root of tooth 36 or the distal enamel of tooth 35)

c. It is quite possible that a tooth is diseased in more than one region or location.

d. It is quite possible that a tooth is affected by more than one pathological disease.

e. Not all the teeth that appear in the radiograph or the question are necessarily

diseased.

f. Remember, marks will be deducted for diagnosis of nonexistent lesions.

g. The number of blanks lines on the answer-sheet do not indicate the number of lesions or X-ray differences. .
