She had this post core for the past 10/15 years. Photo of 11,21 was given with just 2mm of tooth visible which was prepared for core. 1 reason for dislodgement of post core a) vertical root fracture b) something about luting cement 2. what is the significant problem in replacing the post core a)insufficient ferrule 3. Radiograph of 11 &21 with insufficient endo treatment and periapical radiolucency was given. What is the reason for the apical lesion in 11 a) short obturation b) improper lateral condensation c) improper coronal seal 4. probable reason for the apical lesion in 21 same options as above 5. You have decided to extract 11 and 12, what makes I difficult to obtain proper esthetics in the new restoration. Photo of edentulous region of 11,12 given. Forgot the options. V Pedo OPG given. This is the radiograph of 8 or 10 year old girl, who is going abroad in few weeks 1. what is the diagnosis of 75? a) periapical abscess b) dentigerous cyst c)granuloma 2. Treatment for 75 a) extraction b) RCT c) Extraction and spacemaintiner d) Ortho consul, extraction, spacemaintainer 3. Old bitewing of 75 given what treatment would have been done (caries was not involving pulp but near to it) a) pulpotomy b) pulpectomy c) extraction 4. Bitewing of 84 , what is the treatment for 84 (Caries was almost touching the pulp and the marginal ridge was not intact indicating that pulpectomy was reqired) options were same as above 5.This question was about this child’s follow up abroad…..about ortho..mmm can’t recollect VI Mercy is a 55 year ld lady who is your regular patient but did not visit you for past 3 years. Now when she has come to your surgery, you could see multiple carious lesions. ( a photo of maxillary incisors with proximal carious lesions and also in posterior teeth given) 1. reason for these carious lesions a) change in salivary composition b) change in her medication c) ……. 2 what is your immediate next step or immediate treatment a)GIC b) composite c) stopping or ceasing the causative agent 3. If she decides to get the maxillary centrals extracted and wishes to keep the diastema what would be the best replacement option a) implant b) RPD c) Cantilever …some tooth was mentioned d) FPD Two more questions were there for this scenario which I forgot. VII A twenty year old male had a bar fight yesterday. Today he wakes up with pain and deviation of mandible & notices that his upper and lower teeth are meeting when he bites. PA skull radiograph was given 1. What can u see in the radiograph a) left sub condylar b) left condylar c) left subcondylar with displacement d) no fracture 2. according to Australian Medical council guidelines (or something lie this) how many standard drinks an adult can have per day a) one b) two c) 3 d) 4 3. one standard drink equals how much? a)10ml b) 12ml c) 15ml 4. what is the treatment for this fracture a) open reduction b) intermxillary fixation c) arch bar… 5. What are the long term consequences VIII A 60 year old lady is taking alendronate from 2 years for osteoporosis. Her OPG was given. She had chronic periodontitis Furcation involvement in 46 1. What is the treatment for 46 a)furcationo plasty b)tunnel prep c)scaling d) scaling and root planeing 2. Mandibular anterior( iguess 1 or 2 mandibular anteriors) had severe resorption and so they were to be extracted. Following extraction while u place the RPD which major connector will u choose a) Lingual bar b) Lingual plate Three more questions were there for this scenario which I cant remember. MCQ’S 1. The best way to treat a tooth in which ledge has formed a) stop the prepration and obturate b) with a thin file go past the legde and prepare the canal c) 2. Most common cause of pain following obturation a) high point b) microbes left behind c) insufficient coronal seal 3.

Radiograph of dens invaginatus given, what is it or what do u do a) check the other side tooth b) apply fissure sealent 7 which of the following is not true about cherubism a) will regress with age b) teeth will show delayed eruption c) some other options I forgot, wrong one I cannot remember 8. which is the most commonly exposed pulp horn in permanent molars 9. Question on hydrodynamic theory 10.Treatment of cementoma 11.Frankfurts horizontal plane is 12 Initial force while extracting a tooth should be a) excessive b) directed apically 13 before extracting a tooth of a patient who had undergone joint replacement an year ago a) no need of antibiotics b) give prophylactic antibiotics only after consulting orthopediction c) give 1gram of amoxicillin 1 hour before the extraction 14. one question on the angle of the curette 15. to check the furcation of maxillary molar u will probe a) mesial, distal, midfasical b) midfacial, midlingual 16. advantage of acrylic over the co-cr immediate denture a) possibility of adding tooth b)heat conduction c)cost 17. IOPA Radiograph of a anterior tooth root with a post, apical third is underfilled and vertical # what is the source of abscess a) underfilled canal b) # of root 18. one question on cleido cranial dysostosis 19.In an MO prep inlay the mesio distal movement is prevented by a) occlusal stops and dovetail b) acute axiogingival line angle c) givival bevel 20. one question was on proximal reduction or some reduction of SS crown. Now I don’t remember the options.
