[Sarna]

drpuri18, sarna:
can we give this high dose in old patient also, i was wondering if choice is not nitrous oxide.??

I am not sure if a dose appropriate to an adult can be regarded as such for an older patient. Barbiturates are not so safe. I don't have any reference for that.
Let me know if you find anything..

Salivary glands. --ans
Teeth.
Sweat glands.
Hair.
Fingernails.

I have contradictory material which state that salivary glands can be affected and other which state that thay can 't.

Leda,
salivary glands develop near the junctional area b/n the ectodem of the stomatodaeum and the endoderm of the foregut, it is difficult to determine whether they r ectodermal or endodermal.
hence this answer!

Hi, brain in dds, pl see below.

teethie,
since i m unable to copy n paste the link i found frm google book here, do check oral pathology book in google book n u'd see it's called papilloma...
however, adenoma is purely epithelial... i.e. glandular neoplasm

Acc to the textbook of oral pathology, by Ibsen, Saunders.... page # 258,
the very frst sentence under papilloma reads, "the Papilloma is a benign tumor of squamous epithelium that presents a small exophytic pedunculated or sessile growth."

wht do think? check back, plz!

here we go!!!
both papilloma n adenoma r epithelial origin, however, papilloma is due to simple squamous epithelium n adenoma is due to simple cuboidal epithelium.
like i said earlier tht adenoma relates to the glandular epithelium, all glandular epithelium r made up of secretary epithelium and secretary epithelium r made up of simple cuboidal epithelial tissues....

now where r we standing?

 

[drpuri18]

Q.We seat a full crown on a patient on mandibular 2nd molar. as pt closes his mouth and teeth come into contact
patient jaw deflects to right. Before rx patient occlusion was ok. To regain stability we have to adjust the crown
on which incline of which cusp should we make adjustments?
incline cusp
inner(lingual) facial
outer(facial) facial
inner(facial) lingual
outer(lingual) lingual

can anyone explain are we talking about w or nw side?

The question was related to squamous epithelium- so the answer is papilloma

 

[drpuri18]

Which crown is it exactly?

..It is not mentioned...The ques is just like that the way I have posted

 

[Sarna]

..It is not mentioned...The ques is just like that the way I have posted

I believe that the fact whether the crown is on the left or on the right may be important. Otherwise we do not know if the mandible deflected toward the side with a new crown or the opposite..

 

[Sarna]

hey,

Why this answer teethie? INR is meant to assess PT in patients on anticoagulants. I think bleeding time might be the answer

The X-ray beam usually displaces lingual roots in what direction on the radiograph?
a. Same direction as beam just thinking of s.l.o.b. technique...
b. Opposite direction of beam
c. Does not displace Buccal roots
d. Vertically.

folks, correct n cnfrm, plz!

 

[teethie]

yes it is SLOB rule.

folks, correct n cnfrm, plz!

 

[drpuri18]

yes it is SLOB rule.

yes it is SLOB rule but if the ques states tht instead of x ray beam its x-ray cone then ans remains the same or changes pls explain?

 

[drpuri18]

folks, correct n cnfrm, plz!

Wht I feel is the ans shld be opp to the direction of beam..say if the beam is directed from mesial to distal then the lingual root will move towards mesial thus it is moving opp to the direction of beam...where as cone is fixed if the cone is on mesial side then linual root moves towards cone ...

Pls correct me ..I m confused
