eye down droops
paresthesia

 

[aphistis]

to chk bone volume radiograph:
a)bwx
b)pa
c)pan
d)substraction

Bitewing, and the most common oral surgery blade is a #15.

 

[perav]

2)Onion Peel look on the radiograph is characteristic of what?

EWING SARCOMA

could be also garre's osteomylitis

 

[doc toothache]

10)Which of the following is least likely to cause progressive perio problems?
#Soft tissue injury
# Ill- fitting of a restoration
# Rough margins of a restoration
# Within Biologic width

soft tissue injury??? perhaps

Least like to cause progressive perio problems is"
Within biologic width!

18) Patient presents to clinic with a palatal constriction of 3mm. Would the cross bite be:
* a. Shifted to the affected side
* b. Shifted to the unaffected side
* c. Bilateral

its c

A 3mm constriction is not enough for bilateral cross bite. The shift would be to the affected side.

 

[mesh]

how much palatal constriction is req to have a bilateral crossbite???

 

[doc toothache]

how much palatal constriction is req to have a bilateral crossbite???

In the first molar area we may be looking at 6mm.The degree palatal constriction will depend upon the position of cup tips, which may vary from end-to-end contact of the facial cusps to full crossbite where the tooth or teeth are either fully facially or lingually positioned relative to the opposite arch (mand/max).

 

[mesh]

which previous exams are important?? 2000 onwards???

 

[ash23wariya]

yES, IT S SEEN IN ALL PERIOSTEAL reactions, like osteomyletis, osteosarcoma, langerhans etc....

could be also garre's osteomylitis

14) What does the Weight and height stand for in recordings?
* Ordinal
* Nominal
HI ! Dentistgal, I think ans. is Interval.....
Explanation- Interval scale uses a scale graded in equal increments.In the scale of length,we know that one inch is equal tp any other inch. Interval scale allow us to say only that two things are different,but by how much.If a measurement has a mean and a standard deviation,treat it as an interval scale.It is also called a "numerical scale."

Eg- Height
Weight
Blood pressure
Drug dosage..

I hope it helps

thats true .

nominal scale is exclusive and exaustive .like a social security number ;

ordinal scale has rank order . from small to big like cell ,tissue ,organ body

interval scale like body weight , etc , they r additive

Ratio scale has a 0 starting point .eg Kelvin temperature scale .

Calcium hydroxide is useful as a pulp capping agent because it

1. provides a soothing action on the pulp.
2. provides an irritant-type action on the pulp.
3. provides good thermal insulation under the restoration.
4. has a high crushing strength and, thus, protects the exposure site.

 

[mesh]

The time for most finishing and polishing procedures for an indirect cast restoration is

1. only after cementing the casting.
2. before and after cementing the casting.
3. after the casting is tried on the tooth.
4. before the casting is tried on the tooth.

 

[dentistgal]

Thanks for the correction on the scale question . mesh i think the answer to teh question on finishing and polishing of casting is before it is tried on teh tooth . ie D option

1. only after cementing the casting.
2. before and after cementing the casting.
3. after the casting is tried on the tooth.
4. before the casting is tried on the tooth.

I would like to answer it as 2. before and after cementing the cast.
Prior to cementing you need to try-on the inlay, check it if it fit - especially the occlusal margin area, any contact disharmonies with the opposite tooth - using and articulating paper. After cementing - we need to polish it again especially at oclusal margin area giving a casting material better seat on the tooth, ductility property of metal casting alloy can be achieve with burnishing the margin area after cementing before cement set.

CA(OH)2 irritaes the pulp and causes the formation of the dentinal bridge.

 

[LKY]

CaOH is a materials that caused pulpal irritation not to sooth. CaOH have an alkali PH that stimulated the dentin. Eugenol is the material that have a palliative effects on the pulpal.

3)Air/ Water Syringe after endo, what happens from debris into sulcus

The air / water syringe during or after filing will cause the debris push into the apex - debris is trap inside.

4) What has the least root surface area in mm squared?
* Mx Lateral
* Mx Central
* Mnd 1st PM

Max lat Incisor

5) Upright a Mnd 1st Molar with lingual and omega loop? What happens?

tilting of anterior teeth
over tilting
????

The question is vague, but I try to answer it. Uprighting the mandibular molar is not an easy task, because of the tooth size. Every force applied have an equal and opposite reaction. When uprighting a molar, the opposite force reactions will cause intrusion and flaring of the anterior teeth. - Titling of ant teeth. Meanwile on the molar region istself will extrude.

7)Pulpectomy and filling a Mnd Molar, where would you most likely perforate?

Mesial lingual

9)Small white lesion on the tooth the patient’s whole life. What caused it?
* Hypercalcification during the first 6-12 months

no idea

16)Best instrument for SRP of Distal Mandibular tooth?
# Gracey 1/2
# Gracey 9/10
# Universal 13/14
# Gracey 13/14

Gracey 13/14 ; Gracey 1/2 for anterior tooth and 9/10 posterior teeth buccal and lingual; Gracey 11/12 mesial posterior teeth

17) The exact mechanism of Caries dyes (detectors) in effected and affected lesions.

23) What asthma drug causes oral fungal infection?

24) Why do you give Hydralazine with Chloral hydrate patients?

25) Why do you replace faulty amalgam with Cast gold restoration?

q) what tooth is most commonly involved in vertical root fractures???

root canal treated tooth due to the pressure of condensation of gutta percha

 

[perav]

1)what is similar to the lateral periodontal cyst???
Dentrigerous cyst
residual cyst
primordial cyst
traumatic cyst
median mandibular cyst

dentigerous cyst since that is the ony one attached to the tooth .as the tooth erupts the cyst can move laterally .


2)tearing of the flap is MOST commonly

repeated incision in the same place
envelope incision
semilunar incision

semilunar incision due to lack of visibility

Q)what forcerp do u use for a broken mesial root of a mandibular molar?
crayers
cranes

cryers

Q)which of the following is the endocrine involvement that is related to the jaw deformity:
acromegaly
cherubism
albrights
pagets

acromegaly .(pitutary gland produces exces growth hormone )

 

[perav]

11)When dealing with furcation, Guided tissue regeneration best used with Osseointegrated bone graft. Prognosis of tooth with GTR is better in Mx molar than with Mnd molar.
# True or False of each statement

false .it is better with mandibular due to presence of 2 roots Vs threein maxillary . easy access .i guess

which space cause infection of mediastenum .retropharyngeal space [/B
This potential space lies between the alar and prevertebral fasciae. It is patent from the skull base to the diaphragm. Its upper part is the retropharyngeal space, which lies between the prevertebral fascia and the buccopharyngeal fascia on the outer surface of the pharynx. Lymph nodes are present in this space.

Pathological walling-off of infection usually occurs in the retropharyngeal space, but no anatomical barrier exists to the spread of infection downward into the mediastinum. The lower part of this potential space extends behind the esophagus, through the superior mediastinum, and into the posterior mediastinum. ]

15) When do you fill the tooth with CaOH?
* 1st week into splinting
* After 14 days splinting
* Resorption

after 14 days of splinting to allow the PDL to heal . if put before complete healing will cause inflammatory resorption
Q)when you use use ziinc oxide in a primary tooth what kind do you use
with cataylst
without catalyst

without catalyst as catlyst hinders the resorption of the root .

# how do you transfer patient in a wheel chair

# histology of ameloblastoma .

histologically . it represent a island of epithelial cells in a stroma of connective tissue .Cells in the centre of the epihelial islands resemble stellate reticulum but may undergo squamous metaplasia to become Keratinizing squamous epithlium . the cells at the periphery of the epithelial island are tall and collomnar , that rest on basement membrane and seperate the island of cells from the rest of the stroma .the nuclei of these cells is found at the end of the cell . away from the basement membrane a feature referred to as reverse nuclear polarity .

# The exact mechanism of Caries dyes (detectors) in effected and affected lesions.
Carious dentin is made up of two distinct layers. There is an outer layer of infected carious dentin which is soft, discolored, nonvital, nonsensitive and cannot remineralize.There is also an inner layer of uninfected carious dentin (also referred to as "affected" dentin) which is vital and sensitive, not infused with bacteria, and may be somewhat softened and demineralized, but which is capable of remineralizing. Research indicates that the dye in the caries detector bonds to the denatured collagen which is present in the outer infected dentin but which is not present in the inner uninfected dentin and normal DENTIN .

What about when there is loss of alveolar bone ? that is not reversible .

 

[perav]

What about when there is loss of alveolar bone ? that is not reversible .

yeh . but it does not actually measure the depth of the pocket so we have no correlation between height of bone and the crevice of gingiva . here in russell we only asign a number to the tooth that has advanced perio disease ie 8.
whereas with the ramjford index we have reversible as it measures the soft tissue condition and irreversible as we measure the actual pocket depth so we get the depth of the crevice as correlated to height of alveolar bone .
