periodontal pocket epithelium
a is not colonized by bacteria
b does not contain anatomically and physiologically distinct zones
c is a site where immunological elements interact with pocketbacteria
d does not provide a barrier against bacterial invasion

c is a site where immunological elements interact with pocketbacteria
d does not provide a barrier against bacterial invasion

ans C-not sure consult others too

i thought so too but im confused is the pocket not permeble to bacteria i thought bacteria could transverse the gingiva to the connective tissue
i am also bonfused on how barbiturates are metabolized
a oxidation
b reduction
c hydroxylation and oxidation
d sequestration in body fats
i know the answer to be redistribution from 10 yrs but thats not a choice here

it is c i believe
Phenobarbital, pentobarbital, cyclobarbital etc.: oxidation of substituents R1 and/or R2 at C-5 ® hydroxylation, carboxylation etc. followed by conjugation (mainly glucuronides). 25 and 50% of phenobarbital and pentobarbital, respectively, are excreted unchanged.

d does not provide a barrier against bacterial invasion

i think the answer is D
According to Carranza u can see filaments , rods and coccoid in intercellular epithelium along with P. gingivalis they traverse the basement lamina and invade subepithelial CT.
what r the immunologic elements that interact with bacteria there.
correct me if i am wrong.
thanks

ive really been researching these questions and the answers are barbs are metabolized by oxidation and methylation
also in perio pockets the epithelium is a place where phogocytosis of bacteria takes place hence c is answer
the pocket membrane is semipermeble it seems according to literature that in disease it becomes open to passage of some bact but mixed opinions are there some say only bacterial toxins cross over however according to these choices c is the best suited

i also have one more question
does overbite increase when a first molar is lost

i also have one more question
does overbite increase when a first molar is lost[/QUOTE]
wild guess
if 1molar is only posterior teeth then dont u think it is possible ????correct me plz

in the question in perio pockets it says immunologic factors interact with bacteria so i cud not find those factors and in carranza clearly says that bacteria traverse basement membrane and are found in underlying subepithelial connective tissue.
i hope u r getting my point please do correct me if i am wrong
regading when u lose 1 molar overbite decreaes and lower facial height also decreases
thanks

the answer shud be C u r right ichecked again it is C
Thanks

I guess the answer is C
May be m not sure
the crevicular fluid is rich in antibodies IgG (most probably). that will obviously seep into the epithelium and provide immunity against bacteria.

Thts wot my logic says. let me kno the answer also if u come to kno.

hey
concerning ortho question
how can overbite decrease when 1st molars r lost
m not sure bout this
coz i thing , only when both molars r lost there is no posterior stoppage. jaws will close more n will decrease lower face height which eventually will increase overbite. ( deep bite). the anterior teeth in normal occlusion dont contact. so after loosing molars ( 2 in no.) the jaws close more till anteriors come in contact. so increase in overbite
i think so. pls check it again if m wrong.
