ok my friends,
here is one more q for ya all

what is the most likely outcome of a patient with hepatitis c who has periodontal dosease and abcessed teeth drains into medial soft tissue and another tooth shows a large carious lesion with pain

-
-
-development of chronic hepatitis
-development of hepatocellular carcinoma
-

????

i missed it sorry ---->hepatitis c

now do you have any idea about this q

 

[Typo]

i missed it sorry ---->hepatitis c

now do you have any idea about this q

Chronic hepatitis is the most common outcome. Carcinoma can occur, but is less common than chronic hep. The other stuff on the teeth is just filler concerning this question, since it's a testlet.

 

[confused tooth]

Me thinks it is Hepatocellular carcinoma......as Heptatitis C in itself is a chronic disease(Hep A , is the acute ) and the outcome of chronic untreated hep is carcinoma(but I dnt recollect reading specifically hepatocellular carcinoma), but shud be it as the target organ for Hep is liver!
Correct me if I am wrong !! 😕

2) 2% gluteraldehyde is used in what kind of technique

can somebody explain this for me,pls

it's hemolytic anemia

hi i think it is myelophthisic anaemia-
all haemolytic anaemias (not acute cases),bcoz of chronic blood loss ,present as fe def. anaemia(long term cases) .Chronic blood loss with insufficient supply develpos as microcytic anaemia
but myelophthisic anaemia,is a case of myeloproliferative disorder where increased marrow cells later result in anaemia,which is not microcytic

but, if anybody does not agree with this,plz let me know................as even i am not very sure about it

see, with no intentions of contradicting,ur site absolutely supports normocytic,but,even in classifiaction and clinical investigation of the site send by you,it says normocytic anaemia includes only those cases of HA which are characterized by increased blood loss
in another site,of chronic HA besides these two,one can develop megaloblastic anaemia,bcoz of def. of folate and vit. B12 which develops later
in nutshell, the haematologicl report of HA varies depending on the cause of HA and the duration of HA
recent onset case---------------mormocytic
massive loss and prolonged---------microcytic
chronic cases deveolping folate def. and HA due to G6 PD def---will not be normochromic

but,thats what i think.......................waiting for youe answer

1. When viewed sagitally, which of the following teeth have their long axes at an angle LEAST perpendicular to the occlusal plane?

A. Maxillary incisors
B. Mandibular first molars
--------------------
2. Which of the following teeth is wider faciolingually than mesiodistally?

A. Mandibular first premolar
B. Maxillary first molar
--------------------

For #1 - I realize that the mandibular first molars have a lingual inclination, but don't the maxillary incisors have the strongest inclination (facially)? Also, it seems like in a sagittal view you wouldn't even see the lingual inclination of the mandibular molars.

For #2 - I thought both of these was wider faciolingually than mesiodistally? The only teeth I had pegged as wider mesiodistally are the maxillary incisors and the mandibular molars. Any ideas?

C2. Remember the mnemonic "C3, 4, and 5 keep the diaphragm alive." If you cut C2, you'll lose all innervation to the diaphragm. If you cut C6, you'll preserve innervation to the diaphragm.

hi
as far as i remember,glucose once phosphorylated cannot move out of plasma membrane,and its glucose becomes g-6 -phosphate by hexokinase

3) i think cold sterilization does not include gas phase,where we simply dip the solution in a solution at room temp

Glutaraldehyde (cidex) is a disinfectant and not sterilizer.
Sporicidal activity separates disinfection from sterilization. only the flwing methodes sterilize:

1-Autoclave = steam heat 121'c 20-30mints 15psi
2-Dry heat = 160'c 1-2hrs
3-Formaldehyde/alchohol/heat (chemiclave) = 132'c 20-30mints, 20-40psi
4-Ethylene oxide= "Gas" no heat, 8-12 hrs
5-Bead sterilizer= for endo instruments 475'c 15-20 seconds.

 

[wise146]

I don't agree--gluteraldehye is a sterilant just requires many hours though

Disinfectant action:
Disinfectantats act by protein denaturation, alkylation of DNA/RNA, oxidation of sulfhydryl groups or other methods

Glutaraldehyde (Cidex) = protein denaturation and alkylation.

Please let me know .

Glutaraldehyde is a colourless liquid with a pungent odor used to sterilize medical and dental equipment.

can you tell me where did u get the first q caz the coices does not make ant sene to me,if u cut the n5 from medulla u lose everyting not only sensention but also motor innervation,

Hi,
dna conc is highest in g1 and decreases in s and then rises a little in g2 and these are all interphase parts.so the likely ans is between g and s or the m phase.

-----
The sympathetic innervation to structures of the head and neck is distributed via the

A. blood vessels.
B. fascial planes.
C. lymphatic vessels.
D. hyoid musculature.
E. cranial nerves III, VII, IX, and X.
-----

Should the answer be A? In Netter's I only see sympathetic innervation traveling with III and VII; the vagus doesn't carry sympathetics as far as I know.

Final ans A as i think they travel with bv and E should be choice for para.Please let meknow if I'm wrong here.

1.a mouth rinse contains 0.05 % F .which of the following represents the conc expressed as ppm F?

2.a pregnant women took large doses of tetracycline in the second trimester,which teeth will be effected?
a.all primary teeth
b.primary molar+canine only
c.permanent canine only
d.permanent canine +molar only

 

[cooldeal]

1)ans is c
2) ans is a

correct me if i am wrong

 

[dentist33]

1 is 50 i think coz 1 in 1000ppm
2 is all primary and permanent also i think, pls do correct me if wrong

 

[rturgay]

1 is 50 i think coz 1 in 1000ppm
2 is all primary and permanent also i think, pls do correct me if wrong

1 ppm=1 part per million

0.05%=0.0005*1 000 000=500

answer is 500 for the first one,
second q

there is no way for the permanent teeht germs get effected caz second first permanent teeth buds seen after the birth or just before the birth,
for a pregnant women tetracicline usage shouldnot be exceeded more than 2 weeks for each pregnancy so correct answer is supposed to be primary dentition only
c me if i wrong

1 liter of glucose with 600ml/l is mixed with 3 liters of water the number of mm/l of glucose is?

Isn't it the same 600 (the number of glucose mm/l).


Could anyone explain please.
Thanks in advance

Hi,

To answer this Q we need to use the formula ciVi= cfVf
where c= concentration
V = volume
i= initial values
f= final values

Substituting values for the formula

600* 1 = Mf * 4 ( not 3 for 3litres of water was added to 1litre
of solution)
Solving, Mf = 600/4 = 150 ml/l

To convert milliliters to grams, multiply the number in ml with specific gravity of the substance. for glucose, it is 1.44 So 150 ml * 1.44 = 216 gms = 216,000mg

Now, 1mmol of glucose = 180mg of glucose
So, the final value of glucose in mmol after dilution is 216,000/180 = 1200mmol.

hey buddys, I had to do a lot of searching to finally get this answer. but does any one think that such complicated questions will be asked for the exam. anyway, correct me if I'm wrong,k.

 

[cooldeal]

blue sclera is seen in osteogenesis imperfecta along with tendence for multiple fractures & a patient with osteogenesis imperfecta has dentinigenesis imperfecta i hope u get what i m saying

 

[dentist33]

ok i get it i know that denti imperfecta causes blue sclera .had read somewhere other than this causing blue sclera cant figure it out which thing causes it
ok another question which tooths pulp chamber at cross section is biconcave
same read it somewhere but cant figure it out
