74. 3.6 ml of prilocaine has how much anesthetic a. 72 mg b. 80mg c. 144mg d. 36mg

 

[manasa]

74. 3.6 ml of prilocaine has how much anesthetic a. 72 mg b. 80mg c. 144mg d. 36mg

4% prilocaine is normally used in clinical settings,which is equivalent to 40mg.
So in 3.6 ml , the amt of anaesthetic equals 3.6* 40 = 144mg.

For sensitive Ellis II fractures of dentin, cover the exposed surface with a calcium hydroxide composition (Dycal), tooth varnish (copal ether varnish), a strip of stomahesive or clear nail polish to decrease sensitivity. Provide pain medications, instruct the patient to avoid hot and cold food or drink and arrange for follow up with a dentist.

 

[sonibun]

i guess a

thats right i think i was confuse with 3rd option

 

[sonibun]

plz answer this

what is the optimal amount of force applied by periodal probe in millligrams

 

[bridge]

The answer is B
The fracture involves only the enamel and dentin and also at the incisal third. Pt's only complaint is of roughness and cold sensitivity.
So the treatment is smooth out the rough surface and apply GI it will take care of sensitivity.

serial extraction used for mandibular or max arch

 

[sonibun]

most effected with caries upper 1st molar or lower???

 

[nkhalid]

Can anybody answer these
1-which silver amalgam alloy needs the least amount of mercury?
high Cu,low Cu,admixed ,lathe cut or spherical

2-when probing with 20 mgr of manual pression the tip of the probe should be where in the sulcus?
apical, coronal, or ............to the epithelial attacment,

Thanks

 

[nkhalid]

serial extraction used for mandibular or max arch

Serail exraction is done mainly for crowding in mandibular arch with class 1 molar relationship.
Please corect me if I,m wrong.

 

[nkhalid]

most effected with caries upper 1st molar or lower???

I think it,s mandibular 1st molar, specially mesial of 1st molar.

spherical-least amount of Hg
coronal if we take 25mg as optimal pressure-not too sure ddsays 25grams i dont know what is correct

 

[dentistrylover]

please solve the following question

1. which of the following are clinical sign of gingivitis
a)losss of stippling
b)gingival hyperplasia
c)bleeding on probing
d) increased probing depth

A)1,2,3
B)1 and 2
C)2 and 4
D)4 only
E) all the above

The answer maybee C) because gingival hyperplasia and increased probing depth is more closely related to gingival fibrous hypertrophy (e.g. dilantin therapy) , but again these 2 signs may accompany gingivitis (Although not all types of gingivitis show hyperplasia ( ANUG, Gingivosis) ..

 

[dentistrylover]

For sensitive Ellis II fractures of dentin, cover the exposed surface with a calcium hydroxide composition (Dycal), tooth varnish (copal ether varnish), a strip of stomahesive or clear nail polish to decrease sensitivity. Provide pain medications, instruct the patient to avoid hot and cold food or drink and arrange for follow up with a dentist.

applying CaOH here is useless because it only works when in close proximity to the pulp ( direct or indirect capping) which is not the case here (a small amount of dentin is exposed). In this case, the pulp is hyperemic which is normal after such a trauma so GI is the long term restoration here.But is it the "emergency treatment" ??? got no idea ..

 

[dentistrylover]

Ans. A

Q. intermittent painful swelling in the submandibular
region that increases at mealtime is indicative of
A. a ranula.
B. a blockage of Wharton's duct.
C. Ludwig's angina.
D. a blockage of Stensen's duct.
E. an epidemic parotitis.

Ans. is B. because ranula is a cyst caused by rupture to a major salivary gland duct causing saliva to disperse in the surrounding tissues, and it is mostly painless. But, blockage of warton's duct will cause pain especially at meal time when the submandibular gland secrets saliva which is kept inside because the duct is blocked , increasing pressure , causing pain.

Q . The most likely cause of tooth loss following a tunneling procedure to provide complete access
for a mandibular Class III furcation involvement is

A. root caries.
B. root sensitivity.
C. pulpal involvement.
D. recurrent pocketing.

ans is A. because pulpal involvment can be treated by pulpectomy, recurrent pocketing and root sensitivity can be treated by perio therapy, but root caries especially in the furcation area is mostly treated by sectioning the tooth and extraction, which means losing the tooth.

Q. With the development of gingivitis, the sulcus
becomes predominantly populated by
A. gram-positive organisms.
B. gram-negative organisms.
C. diplococcal organisms.
D. spirochetes.

Answer is B. because with "DEVELOPMENT of gingivitis" (not early gingivitis) the sulcus become dominated by gram -ve anerobes.

3.in restoring a canine protected occlusion, with anterior overbite of about 2 mm. the buccal cusps of posterior teeth should be flat, because they will guide the protrusion
a. both are true
b. only the second statement is true
c. both are false

d. only the first statement is true

and explain too

ans is c. because you never flatten any cusps in any type of occlusion and in canine protected occlusion, canine guides all eccentric movements.

hi all ,
I aapreciate any answer t0 these 2 Qs:

smoothe surface caries at localized areas on:
Outer surface of enamel and dentin
inner surface of enamel
outer surface of denind
outer surface of enamel
inner surface of dentin

 

[noosha]

also:
cleft lip and palate uasaully result from:
1:failure of proper union of the median and lateral nasal process
2:failur of union of median nasal process with lateral nasal and maxillary process
3:anhidrosis ectoderma dysplasia
4:failur of development of both the lateral nasal and maxillary process
5:none of the abov

I think the answer should be 2, because only a small amount of dentin exposed and just one hr ago.

 

[noosha]

thanks for the reply.but are u sure the answre is outer surface of enamel?
I think outer surface of enamel and dentin is correct.
cheers

Hi there,
Plese refer to the following link
http://www.usc.edu/hsc/dental/PTHL312abc/312b/09/Reader/reader.html
They are asking about the localized area , can it be the inner surface of dentine?????
Please if anyone has better explaination, share it.
Thanks

Hi,
Totally changed pattern, every question was confusing in the second part . I really dont know what,s gonna happen. I,m depressed.

 

[sonibun]

exam was total disaster

 

[bridge]

Hey Guys

Don't loose heart. It was a tough exam but for everyone and so the overall percentage will come down so dont worry.

Also I would like to suggest something- I do understand that you have just finished the exam and need sometime off studies but dont take too much time off and get back & study again and write the september exam as most universities will accept the september score too.

All the best guys and I hope each one of you gets excellent score.

 

[copper n cattle]

HI
I want to know that what language test u guys are taking or have taken (e.g,TOEFL,IELTS etc,etc,).I have taken TEFL IBT and got 84 but UWO requires 86 and UofT requires 100.so,i want to know that which test you suggest regarding this.Well key for success in IBT is time management and not the language..so,pls if anyone can guide me correctly from his experience or opinion i will appreciate that..

thanx
