can someone try to help answer questions:

Daily cleaning of root surface by the patient has been shown to
a. cause root sensitivity
bcause root resorption
c. stimbulates epi attachment
d. allow remineralization of root surface

i think it is d
 
Heredity is the right answer. Most common habit causing malocclusion is thumbsucking.
For the second one i felt oral cavity has lots of microorg compared to milk. If milk is not accessible then under the tongue is good as it maintains the moisture and has a neutral pH.

Also check this out.
Numerous studies support the use of Modified Eagle's Medium, Hank's Balanced Salt Solution (HBSS), ViaSpan, saline, milk, and saliva as storage media. A recent study has suggested that chicken egg white may also prove to be a suitable storage medium for avulsed teeth. Of these media, only saliva is always present at the scene of an accident, however. Milk can usually be obtained on short notice, but even 10 minutes of desiccation can affect the outcome of replantation. From a practical standpoint, milk packed in ice seems to be the best alternative for the temporary storage of avulsed teeth, due to its wide availability and the minimal detrimental effects it has on PL cells. There is no evidence to support the suggestion that HBSS or any other media will "reconstitute" the PL cells when the extra-alveolar duration of avulsed teeth is greater than 30 minutes.
 
if a tooth need endo tx and perio Tx aned a crown. the tx plan will be :
A) ENDO THEN PERIO THEN CROWN
B) PERIO THEN ENDO THEN CROWN

PLEASE SOME ONE CAN ANS THIS QUESTION.
 
max ridge with bone resorption gets?
a.wider and larger b.wider and smaller c.narrower and smaller ....ANSd.narrower and larger

after doing RCT, the success can be determine by all the following except
a loss of periapical radiolucency on the radiograph ANS
b. formation of apical scar
c. absence of pain......
d. absence of exudate
not sure abt first one
THE ANS IS (A )BECAUSE the lost of the radiolucency can take more than a year to desapear. and the pecense of this does not mean infection. after a rct. so this is the right ans. :laugh:

But usually takes less than a year.. How long does formation of apical scar take?
I guess just about the same..
The question does not specify if it is about long-term success or just after RCT was performed. Additionally,what can we determined just after RCT - only whether the pain stopped or not, but it does not imply success of endo.
"The success can be determined by a loss of pa radiolucency." I think it can be. If the lesion disappeared then definitely we have a success.
In long term observation absence of pain may be tricky as there may be a chronic lesion that increases in size without symptoms..

i think the answer is B. You wud know that the rct was successful if the pt is relieved from pain or if the lesion disappears or if there is no exudate. But if there is formation of scar tissue, u wud not be able to differentiate it from a periapical lesion just by looking at a radiograph. Histology is the only way to differentiate it from a PA granuloma or cyst. so unless u ext or do an apico, u cannot determine that the rct was a success. my 2 cents.👍

exactly 🙂

Nops the ans is absence of pain..I talked to my dentist regarding this and he told me tht there are cases in which pain disappear but the RCT is not a success.THe PA radiolucency does not reduce it remains the same or increase.The apical scar is the healing scar.

I will go withabsence of pain.

Hepatitis B surface antigen (HBsAg) is a protein antigen produced by HBV. This antigen is the earliest indicator of acute hepatitis B and frequently identifies infected people before symptoms appear. HBsAg disappears from the blood during the recovery period. In some people (particularly those infected as children or those with a weak immune system, such as those with AIDS), chronic infection with HBV may occur and HBsAg remains positive.

Which of the following best indicates that a removable partial denture needs to be relined?

  1. There is a loss of retention.
  2. There is soreness on the crest of the ridges.
  3. The indirect retainers are not seated as the extension bases are depressed. ANS
  4. The acrylic resin teeth are abraded and the occlusal vertical dimension is decreased.

this is a relase exam question . this may ans. the question above.

so which is better finally milk or saliva?

milk this is on mosby edo section, as Feelgood said, that only if milk is not accessible then under the tongue is good ........ anyway mosby said that saline is good to even better than saliva, and in other hand just to let you know that the best solution as optimal to storage ar Viaspan and Hank's balanced salt solution (they give the other options because patient will haven't this solution at home, but the dentist should have any of them) you can find that on mosby pag 22 in avulsion

Does anyone understand this question???

If teeth #29,30,31 all need DO amalgams, which one would you do first???


you have to start from #31 because the matrix band will not be causing damage in the new filling when you are placing the matrix band to build the class 2
 
hi, someone have the II L exam I want to know because they have couple question wrong in this exam
 
Questions:

1 relationship of sugar and cavity except one, which one
a. type
b. time
c. amount
d. consistency​
e. concentration

2. dental management of hearing impairment patient ? any ideas ?
3. dental management of patient needs wheelchair to transport ?

4. Studer-Weber syndrome
a. mandibular retro
b. midface ecto​
c. maxillary prog

5. Implant distance from adjacent tooth and interimplant distance?

6. How much submergence is need to provide an emergence profile?
 
hope this helps!

External resorption occurs due to trauma to
PDL
Cementum👍
Pulp
Periosteum

No pulp because is not part of the periodontium, but no PDL nor periosteum, the thing is that the trauma is to the periodontium, even PLD and periosteum are part of the periodontium the principal factor who will cause the ER is cementum, which is part of the periodontium too. in other hand you can have this too on mosby in the table 1-3 pag 24, but where they make you clear that this is the one "cementum" you can find that on mosby pag 23 point A-1 External resorption is due mechanical damage to the cementum surface. endo text book too pathway through the pulp talk about it and said that is because cementoblast make the replacement of the root, and here is the differential diagnosis between external rebsorption and replacement resorption, because with the ER you will see on Xray the PDL between the resorption and the bone but in RR you will not, because on RR is the bone the one that is replacement the root and will be replacement of PDL too and the cementum, overall full tooth will be replacemeted by bone. I hope this help

Thanks Mirell...PDL causes replacement resorption...
Can someone post Pharm questions if u have them....thanks...
 
i think for the 2nd last question, the answer is microabrasion with HCL for treatment of mottled enamel....


yes Chato you were right as in II L Released exam the answer here is microabrasion with HCL as you said , why?, who nows, anyway only to make clear this correction that I did answer wrong

@pepelmas isnt it amount???????/ because if we have dilute sugar in say sucrose in water the effect will be less,..
and if we take barely sugar it will be more

i suppose its amount!!!
correct me if wrong!!
 
hi, my ans are below.
Questions:​


1 relationship of sugar and cavity except one, which one
a. type
b. time -- more the time sugar is in contact with tooth more cavity formation, i wonder why nobody selected this choice.

c. amount
d. consistency
e. concentration

2. dental management of hearing impairment patient ? any ideas ?


3. dental management of patient needs wheelchair to transport ?

4. Studer-Weber syndrome
a. mandibular retro -------------ans
b. midface ecto
c. maxillary prog

5. Implant distance from adjacent tooth and interimplant distance? ------3-4 mm (pl correct if wrong)

let go one by one .
type . very inportant and yes there is a relation. sucrosa and sacarina.
Time. important to know that the frecuency that you ingest sugar.more frecuency more suceptible to decay.
consistency you know stiky consistency more decay.
some one can talk more about amount and concentration the ans. is here.
i think is concentration but it can be amount to.

I think that should be amount, .... and please corret me if I am wrong

The important here is what part will remain with the tooth, I think that pure sugar is more dangerous than dissolved..... then what is more important 20 g of sugar in a small candy eating slowly or 20 g of sugar in a big cake eating fast????? I mean is the same amount but here are diferent concentration and the time, even if you eat the candy fast will cause the same degree of cavity because the concentration that will remain in the tooth is higher than eating the cake..... because the concentration is more pawerful in the candy... what do you think?

i agree with u!!!:luck: even in papesr we have this ques!!!!!!its amount which doent matter coz in the end it will depend on hw much was retained!!!
