What tooth has the most consistent root morphology/canal morphology:

In ASDA's released packet from 1998-2005 it says as one of the answers that it is the mandibular premolars.

In the lecture outline I have from USC, it indicates that the Maxillary Cuspid has the most consistent morphology of 1 canal.

Am i missing something?!? Please let me know what u guys think..from Dschool, I think i remember them saying the Max cuspid as well..but now im not so sure..🙁..please help..

I think thats a typo on their behalf. They also state that the minimal thickness of cavity liners is 15mm (II-M, #64). So who knows!

coumarin may be used if INR is less than 3 for dental extractions. Must weigh risks and benefits of procedure. Needs to be discontinued for oral surgery. Always check with MD before recommending discontinuation of warfarin

Thanks...but Im not too sure about that answer:

Mosby Page 177 in the 2nd column quote:

"most common congenitally missing tooth is the mandibular 2nd premolar followed by the maxillary laterals, followed by the maxillary 2nd premolar"

Page 166 Part D indicates the same thing.

I also used the Kaplan Qbank which indicated it was the laterals..but Kaplan Qbank had TONS of wrong information..so I am apprehensive about taking their word. I hate how all these books say different things regarding certain topics..anyway..any other sources that supports your Max Lateral as opposed to Mand 2nd Premolar?😕

1. On dental deck it is written HIV is the most infectiouos target of standard [universal ] blood precaution but I remember from part 1 it is HBV. Please any one can clarify about this.

2. Natural recontouring of residual ridge int he early post extraction period occurs primarly by resorption of the-
a Crestal bone
b Lingual cortical bone
c Labial buccal cortical bone
d buccal lingual cortical bone

3. 24 hr after elective orthognathic procedure, a patient develops temperature 102 F without local edema or tenderness. The most likely cause is-
a Sinusitis
b Atelectasis
c Dehydration
d Infected Hematoma
e Infective Endocarditis

4.Which of the following is an indication of successful aloogenic tooth transplant-
a Ankylosis
b tooth survives for 12 months
c PDL is re-established
d Both pulp and PDL survive

Kindly give answers with expalnations🙂

if an inital prematuriy occurs in the retruded contact position in the max 1st premolar , the surface of the tooth involved is usually is
1 mesial of the facial cusp
2 mesial of the lingula cusp
3 distal of the facial cusp
4 distal of the lingual cusp

when both nitrous oxide and oxygen tanks are used to one half of their capacities, what are their gas pressures in psi (starting gas pressures are o2 2000, n2o 750)?

Answer: O2 2000 and N2O 750

Why is it psi 2000 for O2?

I know PSI for nitrous doesnt change bc its a liquid and gas and you need to weigh it to see if its empty or not...

A 9 yr old patient has non- carious primary maxillary first molar in infraocclusion. The radiograph shows lack of PDL and radioluscent area that may be noraml resorption.The first premolar is present. The first molar is best managed by-
1 observation
2 extraction
3 routine extraction and space maintenance
4 surgical removal and space maintenance

effectiveness of tooth brushing is best measured by
1 th amount and location of plaque
2 caries experience
3 tooth brush frequency
4 condition of tooth brush

primary reason for splinting teeth with fixed prosthesis
A stabilize loose theeth in favourable occlusal relation ship
B distribute occlusal forces so periodontally weakened tooth dont loosen
C to prevent natural unopposed tooth from migrating
D prevent max CI from separating after closure of diastema

1 A, B, C
2 A,C,D
3B,C,D
4A,D
5ALL OF THE ABOVE

these qs are from decks , but ans are missing in mine

Drink rum! just kidding!. Do old exams, and don't study the day before. What you didn't learn in your weeks/months of preparation time, you will not learn it the day before.

Rock on!
