Mock MSA

Question 1

4 emergency drugs for a dental pracitce

Answer 1

Adrenaline
GTN spray
Glucagon
Aspirin
Salbutamol inhaler

Question 2

4 emergency equipment for dental pracitce

Answer 2

AED
Oxygen mask
Pulse oximeter
Blood glucose measurment device

Question 3

What is dental phobia

Answer 3

Servere dental anxiety - marked and persistent anxiety in relation to situations or objects and interferes on daily life

Question 4

What are the consitituents of PMMA

Answer 4

Powder - benxoyl peroxide - acts as the initiator

Liquid - methacrylate monomer - dissolves PMMA particles

Question 5

Why is the material present as powder and liquid?

Answer 5

It ensures polymerisation shrinkage is minimised
The heat of the reaction is reduced
Processing is possible due to the dough technique

Question 6

2 faults if incorrect ratio of power to liquid for PMMA material

Answer 6

Too much powder - inadequate filling by the monomer of the free space between the powder particles resulting in weak material
Too much monomer - produce excessive polymerisation shrinkage and a loss of quality of fit to the denture bearing surface.

Question 7

Fault if raising the temperature too quickly in PMMA material

Answer 7

If temp is exceeded before the polymerisation process is completed gaseous monomer will be formed, which is the result of gasous porosity.
