Answer: 2
What is the typical average particle size of powered gold used in dental restorations?
1) 15 ?ms
2) 10 ?ms
3) 5 ?ms
4) 20 ?ms
The average particle size of powered gold used in dental restorations is 15 ?ms. This size allows for the gold to be manipulated and condensed properly within the cavity preparation to achieve the desired restorative outcome.
The tooth is tender on vertical percussion. It may be due to
1) Osteomyelitis
2) Periapical inflammation
3) Necrotic pulp
4) Angular bone loss

3. 3.6 mm
4. 0.9mm
Pedodontics
Answer: 1
The average leeway space in the maxilla (both right and left sides) is 1.8
mm.
Leeway space is the amount of space available for the movement of teeth in the
maxilla and mandible during orthodontic treatment. It is calculated by
subtracting the combined mesiodistal width of the mandibular incisors from that
of the maxillary incisors. This space is crucial in determining the potential
for tooth movement, particularly in cases where there is crowding. The answer of
1.8 mm is a commonly accepted average value in the field of orthodontics.
