1. 1st day - Clinical Endo
You will receive a plaster block with 3 teeth (probably one incisor or canine, one
premolar and one molar). You will have 3:15 hrs to do the opening of all teeth and full
endo of one canal. The initial periapical x-ray will be given to you. You will also need
to do a rubber dam exercise (10 minutes for that). For each step of your treatment you
will have to show your work to an examiner and you will have a viva: 1.rubber dam
exercise, 2.opening + length x-ray, 3.prep and 4.obturation. You can take as many x-
rays as you wish, but keep in mind that it will take 5 minutes to process/develop each.
My experience:
I received an upper canine, a second upper premolar and a first upper molar. The tooth
with the simulated periapical lesion is the one to be instrumented, mine was the PM.

34DO. You will receive a picture showing the depths and locations of decay. And 1
amalgam restoration: 26 MOB (cusp capping). You can alter the prep if you think is
necessary, but be ready to explain why.
Time: 3:15 minutes. You have to show your preps and your restoration, you can do in
any order you prefer.
Viva (15 minutes)
They showed me the picture we were given to demonstrate the location and depth of
decays for practical exercise.

8. Pretend this is the bitewing x-ray of your patient. She is coming for the first time in
your practice, she has a 3 months baby and this is her situation today (enamel decay
teeth 33D and 37M, decay at the DEJ on tooth 34D, 1/3 into dentine on 35D and really
deep on 36D), she brings a x-ray 1 year old where we can only see the decay on the 36,
others were sound.

9. CD2 Perio - PM
You will get a patient and a DA. You will have to do the full examination with charting of 1
quadrant and perform scale in 1 quadrant (usually not the one the charting was done) in 1 hour.
Please treat well your patient and your assistant. If the patient needs LA, call an examiner and
they will do it. After this you have 30 minutes to elaborate a full treatment plan for your patient
(not only perio, but all needs). And the last part is your viva.
My experience: my patient was a female, 57yo, medical hx: previous ovarian cancer (had
hysterectomy 7 years ago, no chemo or radiotherapy needed), otherwise healthy. No caries,
moderate chronic periodontitis, lots of plaque and calculus, Class II with severe crowding and
deep palatal vault, severe bleeding, tooth 47 missing, furcation involvement in all molars.
Viva (supposed to be for 15min, mine lasted 25min):
Since my patient did not have any medical complications, my viva was just tx planning and
perio.
*They asked me to present my patient and my perio diagnosis.
*All about different situations with probing depth and CAL: - when do we have pockets but no
CAL? When can we have CAL, but no pockets? Is it possible to have a pseudo pocket with
gingivitis? How did you get your diagnosis?
*All about furcation involvement.
*Endo-perio lesions.
*My patient had a PBM crown on tooth 21, it was not on the quadrant that I charted, so I did not
check the margins, but apparently it was deficient. They asked if I had noticed the crown and its
quality. I said no. They said the patient would need the tooth extracted. How could I temporize
since she has her son’s wedding this weekend? Could I foresee any complications due to her
occlusion? What options for a permanent solution?
*Will you replace tooth 47? Why not?
Day 6

luxated or partially erupted? Bleeding gingival sulcus. Trauma happened minutes ago.
1. What is your management step by step? What is your diagnosis?
After I told I would take a PA x-ray to see if there was any change in tooth position or root
fractures, they told me teeth were partially erupted, with no dislocation after trauma. (if you
need extra information to establish a diagnosis, ask the examiners as you would ask your
patient, they will give you the information if it is necessary).
2. Pain management for this situation? Dosage?
3. What would I tell the parents about possible complications?
4. When will I see her again?

Practical is just radiology, then you have two vivas first radio then oral diagnosis.
Practical: DA will call you and explain everything; you have number 2 and occlusal films
available, as well as holders for periapicals, mirror and tweezers. You will have to take two x-
rays on the mannequin.
My “patient” was a female, 25yo, needed bitewing RHS and periapical of the 16.
Viva:
Radio:

the cartridge? Then you will be taken to the mannequin to show the technique for the IAN
block: tell the landmarks and show technique.
*Which nerves will you anesthetize? Explain technique for IAN, lingual and buccal nerves.
