What is the purpose of a keyed cast?
The root of which perm. tooth has the smallest surface area?

You guys know these?

Dunno about the first one, but I'd expect the second is mandibular lateral incisors.

Moving to Exams & Licensure.

What is the purpose of a keyed cast?
The root of which perm. tooth has the smallest surface area?

You guys know these?

Keyed cast: to allow one to remount a cast on the articulator. Usually after processing an RPD or CD.

Hey guys,

I'm a bit confused about an answer which the ADA has given to the released question below.

Bupivacaine (Marcaine) has all of the following properties relative to lidocaine (Xylocaine) EXCEPT bupivacaine:

1. is more toxic
2. is an ester-type LA
3. has a slower onset of action
4. has a longer duration of action

ASDA's answer is 2. I thought it should be 4, no? Bupivacaine is an amide type of LA and so is lidocaine. So why is the answer 2????? :confused: I don't know, I just find this question to be very weird, especially the way it's worded.

Anybody?

Thanks

dentinal dysplasia do we have periapical granulomas???

least likely place for carcinoma to occur

1 floor of the mouth
2. alveolar ridge;
3.lateral border of tongue

retepeg r lost in which all condition

light orthodontic forces are considered
continuous
indirect
direct
intermittent

what is water based gic and is it better than resin based gic??

light orthodontic forces
direct

I'm sure of my answer. Bupivacaine is definetly an amide and it's mode of action doesn't differ a lot from lidocaine. ANd it's known for it's toxicity (contra-indicated in children)

HI WHAT IS THE INSTRUMENT USED FOR SUPRAGINIGVAL CALCULUS?
SICKLE SCALER:confused:

WHICH INSTRUMENT IS USED FOR ROOT PLANNING?
BESIDES ULTRASONIC SCALER WHAT ELSE??:confused:

WHAT IS THE LAST STEP DONE IN CLEFT PALATE?

WHAT IS THE LAST STEP DONE IN CLEFT PALATE?

For supragingival calculus, you use ultrasonic scaler

For root planning, you use gracey curette from #1-2 till #13-14 (each of them has it's indication)...Consult dental decks

Cleft palate treatment steps : obturator, reparation of the cleft, speech therapy, bone graft, orthodontics, esthetics
