pls help:

1. Max rt. canine facial surface contains a lesion, cervical margin of which is slightly beneath the gingiva, 3mm of attached healthy gingiva ramins. composite will be used, method of approach:
a. retract the gingiva with retraction cord
b. retract with clamp and rubber dam
c. elecrosurgery
ans is b, why not a, is it due to proper isolation?

 

[BENNY4567]

1. dental type3 & 4 gold-cu alloys should be hardened by:
a. quenching immediatly after casting
b.------------------------------- recrystallisation
c. heating to 700C (1300F) for 10min followed by quenching
d.------------ 350C(600-800F) for 15-30min followed by slow cooling
Ans c& d if c will not soften it?

2. most imp. reason for resstoring proper proximal contact in class2 restoration:
a. minimize proximal displacement of restoration
b. minimize pocket formation

4. A typical polymer-reinforce zinc oxide-eugenol cement contains approximately 20 per cent by weight of which of the following in the powder component?
1. Silica
2. Alumina
3. Ethoxybenzoic acid
4. Polymethyl methacrylate

answer is polymethyl methacrylate

5. Which of the following are contraindications for a lateral sliding flap procedure?
(a) shallow vestibule
(b) prominent recipient root
(c) ultra-thin recipient tissue
(d) inadequate amount of keratinized donor tissue

Ans is a, b, d but how b is effective here?

not very sure about this .most probably because if the recipient root is more prominent it will be difficult to adapt the flap.

6. Which of the following components or products of aplaque bacteria are antigenic in humans?
(a) enzymes and other proteins
(b) hydrogen sulfide
(c) polysaccharides
(d) endotoxins
(e) ammonia
Ans is a, c , d why not b too?
I don't think hydrogen sulfide will be the answer as hydrogen sulfide is not antigenic.Mostly the proteins are antigenic

7. Each of the following drug regimens is likely to influence periodontal treatment planning EXCEPT:
1. cortisione.
2. dicumarol.
3. parathormone.
4. nitroglycerin.
5. antihistamine. Ans
But how nitroglycrine effect perio t/t?
most probably because a person taking nitroglycerine will have angina and so some sort of cardiac problem.So caution should be used in treating such patients

8. Maintenance care intervals should be more frequent for patients treated by apically positioned flaps than for patients treated by access flaps because plaque forms more rapidly on root surfaces than on crown surfaces.
Both r wrong but if they r not right?

I can't understand what you want to know,can you explain it to me.
Hope I am right

a. retract the gingiva with retraction cord
b. retract with clamp and rubber dam
c. elecrosurgery
ans is b, why not a, is it due to proper isolation?
the answer is not a because to restore a composite you have to use a rubber dam and moreover it is a class V lesion so in those cases you use a rubber dam with a special clamp

don't know this answer

2. most imp. reason for resstoring proper proximal contact in class2 restoration:
a. minimize proximal displacement of restoration
b. minimize pocket formation
c. avoid food impaction
ans is b, c but i think a is also true?
answer is not a because proximal contact is not useful for retention of the restoration.retention depends on converging occlusal walls,proximal grooves etc.Proper proximal contact is avoids food impaction and pocket formation the sequelae of open contacts

Q. A 44 year old woman requests removal of painful mandibular first molar. She relates that she has not rested for two days and nights because of pain. Her medical history is non contributary, except that she took 20mg of prednisone daily for erythema multiformae for one year, but stopped talking the medication three months ago. The Dentist should:

Correct ans. give steroid supplementation and remove the tooth under local anesthesia and sedation.

I know we have learnt that this is the correct answer, as we need to give steroid supplementation in order to cope up with adrenal insufficiency if any.

But giving steroid will also decrease her immunity, which is also important for post extraction healing.

Please explain the reason of correct answer.

Hi Benny4567,


4. pin technique least like to fracture of remaining hard tissue of non-vital tooth to be restored with pin retained amalgam is one using:
a. cemented pins
b. self- threaded
Ans is a, but isn't self threaded is considered best?

Correct answer is a. Cemented Pins, because it is mentioned that the tooth is non-vital, thus it is brittle, and if you will use self threaded pins then the chances of fracture of the remaining structure will increase, so , in this case the best pin to be used is cemented.
Hope this helps.

[angiematt]

question:

what is the anatomic position of the mandibular canal in relation to the root apices of the molars???
I thought the answer was inferior and lingual but i found this during research......
the mandibular canal was buccal to the apices of the second molar, and in the first molar area the canal was lingual to the root apices

what is the right answer?????
inferior and lingual/ inferior and buccal??

thanx

 

[dentist2013]

@ angiematt---the answer is lingual to the apices of the molar teeth.....

The surgical risk for a patient with organic heart disease depends upon
A. cardiac reserve.
B. blood pressure.
C. respiration.
D. pulse rate.
E. cardiac output.

 

[Endodontia]

Wow!!! What a question! Well Organic heart disease can be of 2 types: Congenital and Rheumatic heart disease. That is all I know! All of the answers make sense, but if I had to pick only 1, I would go with Cardiac output (Option E).

Some of these questions are really starting to scare me. I feel like I haven´t studied anything when I see stuff like this! I hope I pass this exam!

The major difference between Organic and Degenerative Heart Disease is their causes.

Organic refers to a situation where the organ (the heart) is damaged by a specific event. This can also be referred to as "acute", which simply means that it happened suddenly or over a short period of time.

Degenerative Heart Disease (sometimes referred to as "chronic") is caused by gradual deterioration over a long period of time.

And about the above question, I do not know the correct answer but I will go with Cardiac Output.

Establishing drainage is an important aspect of emergency treatment for an acute apical abscess. An
equally important aspect is
a. adjusting the occlusion
b. prescribing systemic antibiotic
c. prescribing appropriate analgesics
d. introducing antimicrobial medicaments into the pulp space

Regarding aesthetics all are true, except:

1. Better when all anterior teeth should be restored simultaneously.
2. Better when individual tooth is restored compared to all teeth.
3. Crown length can be altered by altering the distance between developmental depressions.
4. Crown size can be altered by altering the height of contour.

all of the following reasons to restore erosion lesion except one, which one
a. prevent future erosion
b. reduced sensitivity
c. esthetic

Which of the following best applies to saliva?
1. Phosphate is the main pH buffer.
2. supplies sialiates to mucin.
3. supplies Ca and P for remineralisation.
4. undersaturated with respect to hydroxyappatite at neutral pH.

There are more detached plaques within supragingival plaques that subgingival plaques. The detached plaques within subgingival area are the ones that are more toxic to tissue than attached plaques

2. In addition to bleaching agent carbapol is used.
3. Vacuum from vinyl trays are used.
4. Both arches bleached simultaneously.

. I.V. anesthesia is:
1. Propofol.
2. Sevoflurane.

Hi There , Thanks a lot Lucky and dentist 2013 ,
Thank you very much for your answers ,
I think prescribing anti biotic is not nessecery in all cases so I am doubtful in this case

[persiandentist]

I am not sure about this answer , I think it is better to bleach seperatly to have an index to compare ( I am not sure ) but also carbamide peroxide must be 10%


All are true for home bleaching, except:
1. Uses 15% carbamide peroxide.
2. In addition to bleaching agent carbapol is used.
3. Vacuum from vinyl trays are used.
4. Both arches bleached simultaneously

i don't agree with the answer because carbamide peroxide can be 15% or 25%.
i am sure.
i think it should be 2 or 3.

Which of the following statements about the nutritional management of diabetes is correct?
A. A diet planned according to U.S' Food Guide to Healthy Eating must be modified for a person with diabetes.
B. The Glycemic Index of foods should be used when planning the diet.
C. The fat content of the diet should be 30-35% of energy intake.
D. Sucrose up to 10% of total daily energy intake (e.g. 50% of 2000 kcal/day) is acceptable

MY ANS B ANY COMMENT


PLEASE I'LL BE VERY GREATFUL IF YOU ANSWER THE 3 PENICILLIN QC, PLEASE GUYS SHARE YOUR KNOWLEDGE

 

[Endodontia]

Hey Lucky5. I was between A and B for this question. The reason for chosing B. prescribing systemic antibiotic is because along with drainage we need to debride the canal in order to remove the bacteria, but that is not an otpion. The closest to it is antibiotic. I am not sure if I am right. Does anyone have the correct answer to this?

Evidence from clinical studies shows that dietary sucrose does not increase glycemia more than isocaloric amounts of starch. Thus, intake of sucrose and sucrose-containing foods by people with diabetes does not need to be restricted because of concern about aggravating hyperglycemia.



The Glycemic Index (GI) remains the basic guide for effective management of blood glucose levels. That said, while low-GI diets may indeed reduce postprandial glycemia, the ability of individuals to maintain these diets in the long-term is not yet fully established. Some studies of persons with type 1 diabetes or type 2 diabetes in which low glycemic index diets were compared with high glycemic index diets do not report consistent improvements in HbA1c, fructosamine, or insulin levels.
