EFDA TEST COMPREHENSIVE ANSWERS AND
QUESTIONS SET A+
✔✔specific instruments for composites - ✔✔-smooth condenser
- CVIPC
- 8A
- composite contact former (the one with a double sided point )
- composite gun

✔✔finishing burs - ✔✔*round*= occlusal anatomy
*flame*= interprox
*ET*= for composite

✔✔problems with margins - ✔✔*from filling to tooth* = submarginal (> .2mm is
unacceptable)

*from tooth to filling* = flash/overhang

*catches both ways* = open margin

✔✔*types of occlusion:* maximum intercuspal position
AKA: centric - ✔✔teeth touch uniformly (tap, tap)

✔✔types of occlusion:* lateral excursive - ✔✔slide of jaw left to right

✔✔types of occlusion:* protrusive movement - ✔✔jutting jaw forward

✔✔what is functional occlusion - ✔✔occluding during normal function

✔✔what is parafunctional occlusion - ✔✔occluding while bruxing

✔✔pre-molar anatomy - ✔✔- mesial and distal pit
- central groove
- triangular ridge

, - transverse ridge

for 2nd mandibular pre-molars with *3 cusps*-->
"y shape"

✔✔mandibular 1st molars - ✔✔- 5 functional cusps
- MOST susceptible to decay
- 3 pits (mesial, distal, central)
- *grooves*: 2 bucal & central & lingual
- central groove zig-zags
- NOT SYMMETRICAL

✔✔mandibular 2nd molars - ✔✔- 4 cusps
- SYMMETRICAL
- "+" shape groove
- 3 pits

✔✔Amalgam - ✔✔- Mecanical retension

✔✔steps for restoring class I amalgam - ✔✔Initial: Add copal and blow air

1. condense to *OVERFILL*
(B and then L)

2.Discoid to clean up margins
(from tooth to filling)

3. anatomical burnisher
(form pits and grooves)

4. ceoid or hollen back to define cusps
(the point goes in the groove)

5. check occlusion

✔✔grading for class I amalgam - ✔✔*occlusion:* no high marks
*proximal:* NO
*anatomy:* proper pits and grooves
*margins:* check margins
*smoothness:*smooth look, NOT SHINY

✔✔mercury hygiene - ✔✔- use in well ventilated areas
- use pre-capsulated
-no carpet or absorbant coverings
- use water and HVE
- do not vacuum
