dental caries is initiated by streptococcus mutans initially which survives in a pH of 5.5 and lower. the question mentioned earlier was not a complete one.

GOW-GATES: "true mandibular nerve block". sensory anesthesia to inferior alveolar, lingual, mylohyoid, mental, incisive, auricolotemporal, and buccal nerves. Used when a regular IANB is not successful. Needle is positioned HIGHER so it is distal to the MAXILLARY second molar at the height of it's mesiolingual cusp, still slowly advance until you hit bone (ideally the neck of the condyle), withdrawl 1mm, and then aspirate. If negative, deposit anesthetic.
2 an unconscious patient suspected of having obstracted airway. Management for patient
a. protrude the tongue, clear the pharynx,extend the neck & protrude the mandible.
b. ext. the neck, clear the pharx,prodrude the tong & m/d
c. ext. the neck, protrude the m/d & tongue, clear the pharynx
d. clear the pharynx, extend the neck, protrude the m/d & tongue
Shouldn't that be option c? I mean , the first step of CPR would be head-chin-tilt = extend the neck . And the next steps seems logical - to visualize pharynx, you would need to open the patients' mouth and quite possibly move the tongue out of the way. Please do correct me if i'm wrong - I would appreciate it .

1.) The Bcl-2 gene has been implicated in a number of cancers, including melanoma, breast, prostate, and lung carcinomas, as well as schizophrenia and autoimmunity.
MMP are responsible for invasiveness of ameloblastoma.
p53 is for hpv infection cervical dysplasia n carcinoma in situ.
2. Mutations in gnas gene result in pseudohypoparathyroidism type 1a, pseudohypoparathyroidism type 1b, Albright hereditary osteodystrophy, pseudopseudohypoparathyroidism, McCune-Albright syndrome, progressive osseus heteroplasia, polyostotic fibrous dysplasia of bone, and some pituitary tumors.
3.i thnk 3rd ans is 2nd premolar coz of a slanting prep not sure though...?
dont know abt rays
for last ques i thnk mesial of tooth applying slob rule
anybdy knows pls confirm...

Honestly i think for very well known ones we should know both ( e.x tylenol, augmentin...)
Hatico , I hope you did well. So, how was your experience of part 2 ? Please share.
I am going to write it in few days. Right now, I'm very tense, nervous and freaked out.
All the best for results.

Hi! I do not want to scare you but... exam was difficult and confusing. Much more difficult than part 1. Review Dental Decks. Do not spend much time for released papers - I have 5-7 questions from the papers.
O! Please, know blood chemicals level( glucose and other) in mmol/l. (questions were given in mmol/l, not in mg/gl).
Hatico, any advice you can give about the ortho section? Are there a lot of ortho questions in general? are there some about appliances? What did you think of the pharm section? Are decks enough to study from? Thanks!

if the mandibular left molar is to be saved which of the following surgical twchniques would not be helpful?
1.curettage
2.gingivectomy
3.osseous grafting
4.extraction of tooth 18
5osseous recontouring
why the answer is 2 not 4, pls help? if anyone has explanation thanks

One more: question
Which of the following is the cause of seizures?
1. Hyponatremia
2. Hypokalemia
3. Mypoglycemia
4. Hypophosphatemia.
A friend of mine told me Hypophosphatemia, but I found that Hyponatremia is the answer...ANY HELP?
One more thing: another ftriend of mine, just took Part 2 again and he said that they change already the question system; we can check it out in the Boards web site... 🙁

Original question - Hypoglycemia causes seizures (diabetes)
hyponatremia = low sodium - increased osmotic force - increased water retention in brain causing cerebral edema - can cause seizures
Hypokalemia - Low potassium causing altered kidney functions - seizures as a result of action of vasopressin ?
Question 2 - I would think - do a MO and a DO, assess the amount of tooth structure remaining, if it is <0.5 mm, join the cavities for an MOD. The extent of a preparation is ALWAYS dependent on the extent of caries.
From the NBDE2 Handbook
Three new item types are being introduced on the National Board Dental Examinations
beginning in 2012. The new item types are multiple correct/multiple response, extended
matching, and ordering.
Since these items are considered pretest items they will not be scored. However, they will be
evaluated for their statistical performance and will not have an impact on candidate's results or
pass/fail status.

Amelogenesis imperfecta affects enamel, dentinogenesis imperfecta affects dentin

c.- muco epidermoid carcinoma
9.- the action of the Hawley appliance is mainly
a.- intrusion
b.- tipping ( would pick this).
c.- bodily movement***
– because tipping is the easiest movement to achieve , and bodily movement the hardest – it makes no sense that a removable
Appliance would cause bodily movement of teeth.

a.- coronoid***
b.- condyle
c.-body of mandible
d.- ramus

Guys,
Is anyone clear on these. When do you prefer these:
Cast circumferential clasp
Distal rest/ Mesial rest
I bar/ T bar
Ring bar
I am getting confused, when you have distal undercut, mesial undercut, facial and lingual undercut, where do you prefer what?
Thanks in advance if anyone can explain.

Your patient exhibits the partially edentulous arch from tooth #21 through 29 remaining. Tooth #29 is tilted mesially. The undercut is on the mesiofacial surface. What would be the best clasp assembly for this situation?
1) Distal rest and cast circumferential clasp.
2) Distal rest and WW circumferential clasp.
3) Mesial rest and I-bar.
4) Distal rest and I-bar.
