Theory:

1. Pt comes to you after a fall in her horse stud, age 15yrs f, lower facial asymmetry.Swelling, bruise present. How will you manage this patient ? What are the signs

present if mandibular # occurred. Which # might have occurred? you have a good

availability for radiography, which will you take. Hospital is far away.

2. Youreplanning to extract 28, what are the possible complications which can occurand how will you manage them.

3. Emergency equipment and drugs to be stored.4. Reasons for LA failures.Prac:

My pt was diagnosed with Hep. C and was on antiviral drugs for long time. Smokes

30/day since 15 yrs. Not willing to go for local anaesthesia, wants sleep anaesthesia.

Extraction of 28.

- Liaise with GP, ask for BT/CT. Be cautious about using LA and prescribing drugs ascompromised liver. Caution while handling sharps.

- What are the implications of long term use of antiretroviral drugs ?OR/OM

Theory

1. Post PA anatomical landmarks.2. Caries detection on BW. Negative marking if wrong. Mark deepest part.3. OPG leftside of the mandible, well-defined, radiolucent, round shaped lesion in the

region of 35 & 36 periapical above the inferior alveolar canal. Not resorbing any

internal structures or displacing any external structures.

4. 2 BWs given. One BW not clear. Describe what has occurred in that radiograph(improper contrast) what might be the reasons for failure.

OM

1. Lichen Planus. What is it. C/F. Diff types. What % chances of it being carcinogenic.2. Ulcers. Types of infectious ulcers. Features of traumatic, infectious, and carcinogenic

ulcers.

3.

Part of occlusal radiography showing a large multilocular, well defined radiolucencyextending from 37 to 42 in an 18 yr old patient with buccolingual expansion. No

relevant MH, Medication. Healthy. Describe the lesion, which type of radiograph is it.

D/D. Prov Diagnosis.

4. A photo graph of 26 region, swelling in the buccal alveolar mucosa, pt 60 yr old male.D/D.

Prac

Radio: Right premolar BW & 22 for endo.

Viva:

- BW radiograph reading.- OPG with multilocular, small, welldefined, round shaped radiolucent lesion in 36 &

35 region without any resorption of internal or external structures. (CGCgranuloma)

- Occlusal upper radiograph, showing a large tear drop shaped welldefined,radiolucent lesion located in the periapical region of 11 &21 measuring around 2cm

in diameter. (Naso-palatine cyst).

OM:

- Pink tooth. Causes. Where was the initiation of the resorption started, how will youmanage this patient.

- Photo of leukoplakia, what is it, if lab report comesve dysplasia then what will youdo. D/D.

- Photo of swelling in the palate, soft, noticed since 2 days ago. D/D, what if it occursin 70 yr old male. How will you manage.

- PA of lower anteriors, 41 & 31, patient comes to you complaining of sensitivity whichtooth is responsible for it. 41 had well-defined radiolucent in the periapical region

and 31 had filling approaching pulp but no periapical radiolucent.

Infection Control: Same questions.

CDII

Theory:

1. Pt 38 yr old female, smokes 10 cig/day since couple of years. Generalised Mild tomoderate periodontitis. Underwent extraction of 37 couple of months ago. Her

friends her advising her to take an opinion with the dentist. She is not much concern

about esthetics.What will you check before giving replacement options. What are

the options available. What is your best option. C/F of periodontitis. What will you

expect after you recall after initial Rx. How did you arrive at a diagnosis. Treatment

Plan. What will you expect after you recall your patient.

2. What are the difficulties faced in SRP of 17 region. And what are the instrumentsavailable for cleaning this tooth.

3. C/F Aggressive periodontitis.RPD

1. RPD Design. Upper & Lower.2. Your planning to fabricate a crown on a tooth which is an abutment for current RPD.

Step by step explain the clinical procedures you undertake and What lab instructions

will you give to your lab.

3. Pt is wearing upper and lower RPD since 20 yrs. Now he wants to go for new RPD.Explain what soft tissue changes you will expect in this patient. Before making new

RPD what are the things you will look for.

Restorative

1. Cheung et al. What are the different kind of trauma the tooth is subjected to beforetooth preparation, while preparing, while impression taking, while temporary and

cementation.

2. What precautions will you take to prevent this insults to the tooth during same.3. Materials used in pulp capping. There success rate and outcome.- Ladermix paste, ladermix cement, Ca(oh)2, MTA, and pulpotomy with ladermix

cement.

Pedo: Same questions. Viva: OPG shown: age guess and ankylosed 85 & mangt. BW with

root resorbed tooth 74 reasons. Trauma Slide, missing 11, How will you manage when pt

comes to you after 2 days.

All the best guys.
