أحبابي عندي بعض الأسئلة من الدورات السابقة حبيت أطرحها في المنتدى وأشوف الإجابات
1- Finishing of the surface in one direction and using light pressure will:

b- Create a rough surface to bond with the porcelain
c- A and b
d- None
2- One of the investment expansions is:
a- Setting expansion
b- Hygroscopic expansion
c- Thermal expansion
d- All
3- the facial over contour usually causes:
a- the accumulation of food debris
b- the accumulation of plaque
c- gingival inflammation
d- all
4- the part of the axial contour that extends from the base of the gingival sulcus past the free margin of the gingiva is:
a- emergence profile
b- buccual profile
c- lingual profile
d- all
5- to insure that the finished restoration will have adequate proximal contact with the teeth adjacent to it:
a- the wax pattern should be slightly oversized mesiodistally
b- the wax pattern should be slightly downsized bucculigually
c- a and b
d- none
6- the proximal contacts of posterior teeth are located in ……. Of the crown, exept the maxillary first and second molar:
a- the occlusal third
b- the gingival third
c- the middle third
d- none
7- the proximal contacts between the maxillary first and second molars are located in:
a- the occlusal third
b- the gingival third
c- the middle third
d- none
8- the proximal contacts that are too narrow facioligully will:
a- allow fibrous foods to wedge between the teeth
b- not adequately deflect food from the gingival tissues
c- a and b
d- none
9- the proximal contact that are wide faciolingually will:
a- allow fibrous foods to wedge between the teeth
b- not adequately deflect food from the gingival tissues
