i think the ans is c... by good oral hygiene practice, the pocket depth tends to decrease... tats juz a guess

yes, its D!! bec daily clean the root surface will enhanced hygiene and promote remineralization.

 

[smileyface1]

the answer is that it causes root sensitivity. when the pt brushes over the cementum, it is going to expose the tubules, causing sensitivity.

Yes, i think your answer may correct, ^^ bec I was thinking daily clean root surface is to remove the plaque deposit on surface tooth, and there are acid that under the plaque, which time when remove it, it will allow the remineralization of the root surface..>< thats what i know..

I would go with D too. how do you stimulate Epi attachment !! there is no way to stimulate it unless you keep it plaque free plus doing graft.
allow reminalization would be logical because when you brush or use flouride treatment, remineralization would occur. and that would block the dentinal tubules. I would go with D. cuz stimulation of epi attachment wont happen

If there can be no epithelial attachment then why do we do SRP's and see decreased pockets. The purpose of an SRP is to clean the cementum and disrupt the sulcular epithelium so that you can gain attachment through long junctional EPITHELIUM. So therefor no grafting would be necessary for new epithelial attachment. However that is not the answer to this question because the patient can only clean .9mm into their pocket and wont disrupt the epithelium. So the answer to this question is for remineralization. Daily brushing wont cause sensitivity or else every geriatrics patient that has good hygiene would be in pain. Now if the question stated using an extra hard toothbrush i would be inclined to say sensitivity.

When I said plaque free, I meant by SRP and proper brushing !! I know that epi attachment wont happen if there is still defect in the cementum. I said D is the answer as well 🙂

Does anyone know why Calcium Hydroxide is contraindicated when performing a pulpotomy on a pediatric patient?

 

[drpuri18]

Does anyone know why Calcium Hydroxide is contraindicated when performing a pulpotomy on a pediatric patient?

because it causes irritation that causes resorption in primary where as in permanent it causes irritation that leads to reparative dentin bridge formation. So we do formacresol pulpotomy in children.

I would say peripheral seal is accomplished on the maxillary denture, not on the mandibular thus peripheral seal would be a good answer for the maxillary denture. As for the mandibular, extension to buccal shelf would provide the most support for the denture.

Hey I just read in decks that peripheral seal is the most important retention factor in dentures.

In terms of denture SUPPORT: mandibular = buccal shelf and max= ridge.
secondary support for mandibular is the anterior lingual aspect
secondary support for maxillary is the ruggae.

Hope this helps clarify! 👍

If there can be no epithelial attachment then why do we do SRP's and see decreased pockets. The purpose of an SRP is to clean the cementum and disrupt the sulcular epithelium so that you can gain attachment through long junctional EPITHELIUM. So therefor no grafting would be necessary for new epithelial attachment. However that is not the answer to this question because the patient can only clean .9mm into their pocket and wont disrupt the epithelium. So the answer to this question is for remineralization. Daily brushing wont cause sensitivity or else every geriatrics patient that has good hygiene would be in pain. Now if the question stated using an extra hard toothbrush i would be inclined to say sensitivity.

Under normal circumstances, this loss of calcium (demineralization) is compensated for by the uptake of calcium (remineralization) from the tooth's microenvironment. This dynamic process of demineralization and remineralization takes place more or less continually and equally in a favorable oral environment. In an unfavorable environment, the remineralization rate does not sufficiently neutralize the rate of demineralization, and caries occurs.
Depending on the depth and extension of the lesion, management may include remineralization, There is no doubt that remineralization of a carious root surface lesion is practicable. The remineralised surface is dark brown or black with a leathery texture initially and eventually hardens to a give a polished highly mineralized surface.
So acc. to me ans should be D.

1.A lateral cephalometric radiograph for a patient
with a 3mm anterior functional shift should be
taken with the patient in
A. maximum intercuspation.
B. initial contact.
C. normal rest position.
D. maximum opening.
E. protrusive position.

Acc. to me it should be A.
Cephalograms should always be taken in maximum intercuspation position.
Functional shift is when mandible moves excessively from initial contact position to maximum intercuspation usually resulting in an anterior [ forward shift ] or posterior [ lateral shift ] cross bite.

Anybody else has different point view??????

1)A recently-introduced local anesthetic agent is claimed by the manufacturer to be several times as potent as procaine. The product is available in 0.05% buffered aqueous solution in 1.8 ml. cartridge. The maximum amount recommended for dental anesthesia over a 4-hour period is 30 mg. This amount is contained in approximately how many cartridges?

1. 1-9
2. 10-18
3. 19-27
4. 28-36
5. Greater than 36

2) difference between bur no. 240 and 330?

 

[drpuri18]

Which pulp test can be performed on a tooth with an open apex? ( I do know that EPT is not an option, its a definite no!)

Why do you not use composite restorations on primary molars?

Please help...Thx

we cannot use composite restorations on primary molars because the enamel is prismless and it is difficult to etch.

Pulp test tht can be performed on tooth with open apex ...either thermal tests or percussion..(not sure)

its not recommended to do pulp tests in an open apex tooyh as you would get a false positive response due to large number of blood vessels present at the apex,, correct me if im wrong

cowhorn are used for mandibular - you place the "horns" between the furcation and voila!!!

Concerning last question with least likely allergy.

I think it's epinephrine. No such thing as epinephrine allergy.
You treat anaphylactic reactions with epinephrine.

I think it's epinephrine. No such thing as epinephrine allergy.
You treat anaphylactic reactions with epinephrine.

Allergy to Preservatives

If an allergy test shows that you are allergic to the preservative, a local anesthetic without epinephrine can be used. Because the usual local (lidocaine) doesn't numb for very long without epi, mepivacaine (also known as carbocaine) or prilocaine without epi can be used.

People who are allergic to bisulfites often know about it, because bisulfites are commonly sprayed onto fruit and vegetables to keep them looking fresh. If you have an allergy to bisulfites, let your dentist know about it!

which drug is LEAST likely to result in an allergy reaction
a. epine
b. procaine
c. bisulfite
d. lidocaine

Epinephrine is added to the local anaesthetic for a good reason: it makes it work longer and more efficiently. For example, the most commonly used local anesthetic (lidocaine 2% with 1:100,000 epi) numbs the tooth for one hour, but without the epi, it only numbs the tooth for 5-10 minutes. Epinephrine also acts as a "vasoconstrictor": it stops soft tissues from bleeding.

All standard local anaesthetics contain the preservative sodium bisulfite or metabisulfite. The preservative is necessary to keep the epinephrine fresh (epi quickly deteriorates and becomes useless otherwise). The standard local anesthetic cartridges (called lidocaine in the U.S. and lignocaine in the U.K.) have epi added.
