For those who didn't come to the revision or still blurred about the answer scheme and how the examination works, here it is. (based on last year's exam)

1. There will be multiple microscope in a row. You have a piece of paper, and a doctor to watch over you.

2. Every one will stand infront 1 microscope then the exam start, and you need to see the slide given and answer the question.

3. Answer the question, then within 1-2 minutes, the doctor will instruct to move to another slide (Next!!). Time is crucial, so you should really know every slide with its structure before exam.

4. You may/may not be given a time to check your answer and write your name, group number, etc.

5. Finish.



- The question will be

Photobucket
"Identify the structure shown."
or maybe
"Identify and name the structure within it."

- The answer should be in this scheme:
The decalcified longitudinal section using Hx&E (HxE) showing Late Bell Stage of Tooth Development.
1. Ameloblast
2. Outer Enamel Epithelium
3. Inner Enamel Epithelium
4. Stellate Reticulum
5. Stratum Intermedium
6. Dental papilla
7. Odontoblast
8. Predentin


-The main points here are:
1. State wether its decalcified section or ground section.
2. Wether its longitudinal or transverse section.
3. If decalcified slide, state the stain used : Hematoxylin and Eunosin (Hx&E), Silver Stain, Iron Hematoxylin.
4. State the slide is a structure of ...
5. Then give every structure you can see in the slide.


Tips: Sometime, you can see the slide with naked eye and determine what it is. For example, if the microscope's lens pointed to tip of the crown, then you know, it's a structure within the crown (enamel, dentin etc.)



Hope it help a lil bit.

p/s: announcement from mrs Manal :

This is the past year question for final exam of Oral Histology by chapters. As for now, it is reasonable to believe that everyone of you have found the best way to master the subject. If not, get going! Lots of way - study in groups or answer those question and submit them to the doc and etc. Let the spirit of exam burns in you.
