101. drainage of an acute abscess. Also important is
a. antibiotic
b. analgesic
c. relieve the occlusion
d- through debridement of the tooth

Ans: A

we drain the abscess if pos thru acess opening and thoroughly debride the canal and leave it open . also we do prescribe antibiotics and antiinfl +pain killer.
i rechecked the ans in grossman also !

 

[S vashishta]

well i thought median was the centre of the given set of numbers meaning...
centre of 1111223379
thus centre is 2+2=4/2=2

so u mean , median is middle no ...as of position wise ...no matter wat the no is ! okay then the correct ans shd be 2

 

[S vashishta]

toothie

well im confussed now..wuts the answer for wut vashista gave an example..
if it is 3.5 then.. wuts the answer is it 3rd position or 4th position..??? take as median number? wuts the median then??/ 🙄
le

acc to the formula (reference to toothie's ans)
n+1/2 ...ans shd be 3.5 but in that case in the ans options either 3 or 4 shd be mentioned not both... so u can choose acc.ly

 

[S vashishta]

vashishta.. another thing..for the question on shape of acsess preperation for mand first molar.. the answer is trapeziodal.. which u answered right.. but emntioned rectangular along with it..
the answer is actually only trapeziodal.. cause mesailly the MB is placed very bucally and the ML is placed over the lingual root..
thus that side of prep is larger than the distal side where the 2 canals are present close together. morew towards the centre of the tooth.. so evn though usually when we do preps.. it looks rectangular.. theoretically its trapezoidal...
sorry... just mentioning .. so that if ever the option is between rectangular and trapeziodal..the answer is trapezoidal...

yup I agree trapezoidal is correct form we see even on preparation !
I jus mentioned rectangular as an alternative...but correct ans is trapezoidal

 

[hanan]

thanks.. but how does it affect..i mean which part of the lingual border does it affect...

Hi toothie!
Please check this link: http://www.realfalseteeth.com/RCD/chp4.htmfigure.
Hopefully, it will clear your douts about palatoglossus

155. which is the most common intraoral site for a melanoma
a. gingiva
b. buccal mucosa
c. hard palate
d- floor of the mouth

Journal of Cranio-Maxillofacial Surgery (2004) 32, 251–257
Oral mucosal melanoma: a series of case reports
"In this report, the hard palate and the
maxillary gingiva were the preferred location (50%),this being similar to other reports: Pliskin (1979)found that 77% of all OMM occurred in either the palate or the upper alveolus, Takagi et al. (1974) found 34% out of a total of 120 cases to be in the palate and 24% in the maxillary gingiva"

😕
That's about litterature. Now, from my experience, the only case of oral elanoma I've seen (it's a rare tumour) was located in the upper gingiva. I agree that it not reliable 😛 but what's the answer then?

 

[hanan]

102. recurrent lesions on ono-keratinized tissue in 20 year old female are most likely
a. herpes labialis
b. herpetic gingivostomatitis
c. aphthous
d. shingles

1-Well a recurrent lesion in young patient could be:herpes labialis, herpetic gingivostomatitis or aphthous

2-But when located on keratinized tissue :
- lip mucosa is not keratinized: herpes labialis is then excluded
- aphtae doesn't involve keratnized tissue

So the answer is:
herpetic ginigvostomatitis
Please do correct me if I'm wrong

hey..
sorry to bug you..
couldnt even find removable...!!! nothing.. except home page,faq, products.. that kinda thing...

Hi toothie

I clicked the above link posted by wisdum. The webpage Detail Dental Laboratory has 3 contents Dentures, Gurantee amf Removable Complete Denture. You can click on the alst one (hand sign) i.e. Removable...After that follow the link suggested by wisdum. I have quickly scanned few topics including anatomy Maxillary & Mandibular. Quite helpful. Wish I had this before. I am just copy-pasting Maxillary and Mandibular anatomy:

MAXILLARY COMPLETE DENTURE BORDERS
The following is a list of the significance of and movements or manipulations the dentist and/or the patient make to capture the following important denture border landmarks:

1. Labial Frenum
Usually no muscular fibers in the edentulous state. Must be manipulated by the operator in order to get a more defined recording.

2. Orbicularis Oris
Exaggerated "M" sound.

3. Buccal Frenum Buccinator
"O" or "E" sound or in patients inability to Muscle/Buccinator Insertion manipulate by pulling corner of mouth out and down.

4. Coronoid Process
Lateral border of post malar pocket. Open moderately wide and move mandible side to side.

5. Palatoglossus Posterior border of post malar pocket.
Open wide and place tongue out of the mouth.

6. Hamular Notch
DOES NOT interfere with pterygomandibular raphe (from hamulus to retromolar pad) between tuberosity and hamulus of medial pterygoid plate posterior boundary. Open and close several times.

7. Pterygomandibular Ligament/Raphe
Is pulled forward when mouth is open wide

8. Fovea Palatini
Remnants of nasopharyngeal ducts (coalescence of mucous glands). Always on soft tissues.

9. Post Dam Area
Comprised of tensor palatini; predominantly horizontal fibers Levator veil palatini; predominantly oblique fibers. Uvealis; predominantly vertical fibers.

10. Vibrating Line
Imaginary line - notch to notch, usually about 2mm in front of fovea. Always on soft tissue. Higher vault - more abrupt and forward. Flat vault - more posterior. Denture ends at/or 1-2mm past this line.

MANDIBULAR COMPLETE DENTURE BORDERS
When teeth are lost the mandible gets shorter and narrower bucco-lingually. The crest gets narrow and sharp. The width of bone widens in molar areas as crest resorbs. In the anterior, bone is lost from the lingual and bone appears to move forward. Bone is often at the level of floor of mouth when mandible is viewed from side. Overall, mandibular ridge is high in posterior and low in the anterior.

The following is a list of the significance of, and movements or manipulations the dentist and/or the patient make to capture the following important denture border landmarks:

1. Labial Frenum
No muscular fiber. Should manipulate.

2. Orbicularis Oris
Exaggerated "M" sound.

3. Anterior Masseter
Fibers pass outside buccinator. Muscle pushes in. Clenching or biting closing force while bordermolding will contract muscle.

4. Pterygomandibular Ligament
Open wide. Stretch.

5. Retromylohyoid Posterior Border
Styloglossus, Stylohyoid, Palatalglossus; Place tongue over handle of tray.

6. Mylohyoid
Fibers become shorter or smaller progressing anteriorly. Place tongue into opposite cheek.

7. Genioglossus
Place tongue over handles of tray and wet upper lip.

8. Anterior Portion
Several muscles attached (buccal frenum to buccal frenum). Short flange (mental foramen - often on top of ridge). Labial frenum attached to orbicularis oris sensitive and active.

9. Buccal Vestibule
Extends from buccal frenum to retromolar pad and from crest of ridge to cheek.

10. Buccal Frenum
"OU" or "E" sound if necessary. Connects with band from maxillary thru modiolus. Fibers will pull and must be free to move. Lip must be supported.

11. Buccinator Muscle
"OU" or "E" sound if necessary. Extends from modiolus to pterygomandibular raphe.

12. Buccal Shelf
Bordered: medially by crest of ridge, anteriorly by buccal frenum, laterally by external oblique ridge and distally by retromolar pad.

Buccinator fibers run anterior-posterior and parallel to the bone. Inferior portion attached to buccal shelf. WILL NOT LIFT DENTURE 1 stress bearing area of mandibular denture. Has good cortical bone at right angle to occlusal plane.

13. Buccal flange
Extends from frenum to anterior masseter. Is wide and extends into the cheek to cover buccal shelf.

14. External Oblique Ridge
DOES NOT LIMIT extent of buccal flanges. Flange can extend up to or over ridge - wherever the muccobuccal fold ends. Use the external ridge AS LANDMARK -- TEST FOLDS IN THIS AREA WITH MIRROR.

15. Distobuccal Flange
Masseter region - flange converges medially with action of masseter.

16. Distal Extent
Limited by buccinator and lateral bony process. Denture extends to include retromolar pad which provides a soft tissue seal.

17. Retromolar Pad
Contains some glandular tissue, tendon of temporal muscle, buccinator fibers, fibers of the superior pharyngeal constrictor on the lingual and from the pterygomanidular raphe at the distal.



I am sure you will be able to get into the link.

Good luck

As u said aphthous occurs in the non kerartinized
and Q mention female, and female are subjected to stress more often
so i would say apthous
correct me if i'm wrong

Hi Wisdum!
I apologize! I thought it was keratinized mucosa

the answer would be hard palate.
even though the one clinical case u saw was on the gingiva.. theoretically.. statistics show max on ahrd palate..plus its not that its not found on gingiva.. just that more common on palate...one case is not a statistic....🙂
even shaefer says the same thing..🙂
ans would be ahrd palate

Hi toothie!
I'm talking about statistics.The paper I've mentioned (Journal of Cranio-Maxillofacial Surgery (2004) 32, 251–257) report a series of case of oral mucosal melanoma. And as you could read in my previous post, the results are not clear about the site most often involved by melanoma. That was my point toothie 🙂

hey hanan..
thanks..
i tried opening the link.. but it isnt opening.. tried getting into the home page.. but couldnt find the materaiol..
if u could post it again.. it would be really nice..
thansk..🙂

I'm sorry for having been late to answer. Wisdum did the job for me. Thanks a billion
By the way, I've tried to upload the image instead of giving the link but I wasn't abble to do as well as wisdum 😉

263 to expose a mandibular lingual torus of a patient who has a full complement of teeth, the incision should to
a. semilunar
b. paragingival
c. in the gingival sulcus and embrasure area
d. directly over the most prominent part of the torus
e. inferior to the lesion, reflecting the tissue superior

Answer c.
To raise an envelope flap the incision should be in g. sulcus and then scalpel turned into embrasure areas on mesial and distal aspect to release the gingiva. A Paragingival incision will run along Marginal gingiva, so can not be correct.

when it is over extended it will affect the stability most often so the denture wont be stable.. and when we will check the occlusion and patient close the extended border will push against the resilient tissue,if for example lower dentures so buccal flange will push in the mucoginigival and will displace it, so u wont find out any occulsion disharmny the complain will be either pain or unstable denture that's why when u need to check over extented denture u pull the checks, the lips....
the Question asking about occlusion ,, most often improper jaw relation is the cause

I agree with the logic given by wisdum ...if ur Centric relation and centric occlusion record is not right that will affect the occlusion ...ur occlusion might be perfect even with overextended denture ..with alwayz affests the stablility.

 

[S vashishta]

i checked it out,, according to carl misch dental implants
it is D
It helps diminish pressure on healing bone and soft tissue,
giving implant fixtures additional time to fully osseointegrate

well progressive laoding is advisable and I confirmed it too.

 

[S vashishta]

which of the following MOST accurately explains how biofeedback works
a. it reduced cognitive dissonance
b. it stimulates the sympathetic nervous system
c. it relaz and to some extent hypnotizes the patient
d. it distracts and engages the patient in an active coping task.
e. it enables the patient to gain control of certain physiological function

hi,
i think the answer is E.
remember reading earlier about it on the net...
any idea where to read this topic from.. another ting.. again a multiple of answers present..
which one is right

There are some biofeed back devices available in the market for TMJ disorders inwhich electrodes are placed on muscles which warn the patient of excessive activity and tell the patient to relax and be less stressful..so ans I belv is c coz we cannot really change whats not under our control by jus autosuggestions but whatwe can do is alter the pattern of our behavior ...these devices are useful in cae of bruxism specially.

 

[S vashishta]

i agree that recording jaw relations is imporatant..etc.. i agree with everythign wisdum had mentioned..
but for discussion sake .. im asking why not .... over extended borders..
ure occlusion may be perfect with an overextended denture ,but the patient will percieve prolems in occlusion because everytime they try eating.. it will dislodge the denture....

ya stability is in jeopardy withover extension and becoz of that pat might have trouble ...leave alone eating he wudnt be able to speak even or everytime he'll openhis mouth denture with bother him...but ya as far this ques is concerned ans wud def.ly be jaw relations ...besides think otherway round...jaw relations are not right but margin is perfect...wat do u think then the ans wud be ?
