Please correct me if i am wrong with answer to this Q and also please provide only correct ans no guess

A 9 year old patient presents with a submerged non-carious deciduous first molar. The most appropriate treatment is
A. routine extraction and space maintenance.
B. surgical removal and space maintenance.
C. extraction only.
D. observation.

Ans. B or D ?

33. The use of an etchant and bonding system before insertion of a omposite resin restoration results in
1. improved retention of the restoration.
2. decreased marginal leakage.
3. reduced polymerization shrinkage effect.
4. greater strength of the restoration.
A. (1) (2) (3)
B. (1) and (3)
C. (2) and (4)
D. (4) only
E. All of the above.

Does it have any effect on polymerization shrinkage

Ans. B or D ?

definately D .. dec first molar mand or max..usually falls at about 9 -10 years to make place for the permanent premolars which erupt between 10-12 yrs.

1,2 ,4 are def right... not sure about 3.. will check and confirm..

For this I agree with toothie , it is defnitely D.

Does it have any effect on polymerization shrinkage

I strongly think it is A (1,2,3).
Surely it does not have any effect on the strenghth of the composite restoration becoz ,strenth depends on the inoraganic filler in the resin material.
though it directly does not reduce the polymerisation shrinkage, it indirectly does,that is y they have used the term" polymerisation shrinkage effect".The etchant and the bonding agent resist the polymerisation shrinkag forces.And this again goes onto expalin y there is decreased microleakage.

polymerisation shrinkage is affected by the filler content as is the strenght.

In the first question, why is the tooth "submerged"? I thought this meant ankylosis, which would require extraction and maintain space until the premolar comes in.

Otherwise, what is wrong with the tooth?

hey toothache.. ure right... didnt think of that...submerged tooth does mean ankylosed ...
thanks...!!!

thanks guys
i got it now.its polymerisation shrinkage effect that means microleakage which is reduced and not poly merisation shrinkage but about strenghth ,,,,,,,i'm still confused
plz reply soon.........gag

Does it have any effect on polymerization shrinkage[/QUOTE]

i read a similar question in the released papers yesterday and the ans was improved retension and decreased marginal leakage.
polymerisatin shrinkage and greater strenght were the other options but not the answers.....
