One week after cementation of an MOD onlay on a maxillary molar adjacent to an existing amalgam, the patient reports sensitivity to cold and pressure of the tooth. the most likely cause is

a. hyperocclusion
b. chronic pulpitis
c. galvanic response
d. maxillary sinusitis
e. acid irritation from the cement

 

[JohnDoeDDS]

I'm also interested to know this..
I had a similar situation (except that it didn't take a week so maybe not so similar) and had to adjust the occlusion. I'm not sure if that was the right thing to do but it fixed the problem...

Is the answer hyperocclusion? What is the significance of an adjacent amalgam restoration?

well if u keep amalgam in mind..then it should be galvanic repsonse...

a. hyperocclusion
b. chronic pulpitis
c. galvanic response
d. maxillary sinusitis
e. acid irritation from the cement

It might not be galvanic shock.It happens immediately after cementation and subsides in a day or two.Here in the question it says...one week after cementation.So can it be that?

 

[Lucky5]

Hey guys here are more questions, let's discuss them!!! thanks for you help. I do agree with twinklestar johndoe, I think the answer should be hyperoclusion, becuase it is after a week...

a) intrusion
b) tipping
c) bodily movement

2. A light force applied to the periodontal ligament during orthodontic treatment is considered
a. intermittent
b. direct

If they ask caries in children it is Hispanic.
For adults it more AA.When they dont mention anything it is AA.

 

[twinklestar123]

For the previous question for open apex, it is cold test.I read it yesterday.
Something about carbon dust? which is like -78 degree and difluoro some thing for which it is -50 degrees.

It is definitely the silver that causes green discoloration, and that's why they don't use it anymore (Au-Pd now and NOT Au-Pd-Ag). Check Rosentiel if you still have doubts.
