1.	Porcelain veneers are:
	a.		fixed restoratives
	b.		mostly thought of as cosmetic dentistry
	c.		usually patient-driven
	d.		all of the above
2.	No-prep veneers may be indicated for patients:
	a.		with multiple diastema
	b.		with several lingually inclined teeth
	c.		that are borderline dental-phobic (e.g., prefer no shots or drilling)
	d.		all of the above
3.	The no-prep technique varies from the prep technique in the following areas:
	a.		you are not worried about dentin bonding
	b.		you are not worried about post-operative sensitivity
	c.		temporaries are not required
	d.		all of the above
4.	When using the no-prep technique, no-prep veneers:
	a.		may be as little as 0.3 mm thick
	b.		have supra-gingival margins
	c.		require that the enamel be etched for the purpose of bonding
	d.		all of the above
5.	Regarding the results obtainable using the no-prep technique, it is true that:
	a.		the results usually look better than a prepped case
	b.		all of the spaces between a patient’s teeth may be closed in an hour
	c.		the difference in appearance at try-in will not be immediately noticed by most patients
	d.		none of the above
6.	Candidates for the no-prep technique include persons with:
	a.		several lingually inclined teeth
	b.		persons that do not want local anesthetic
	c.		persons with chips or incisal edge wear
	d.		all of the above
7.	For clean-up of the clear resin cement, what is NOT true:
	a.		an explorer can be used to remove gel-state cement
	b.		Brownie® cups assist in cleaning cured clear resin off of the veneers
	c.		orange sticks can be used to check contacts
	d.		a serrated metal strip can be used to remove cured cement between the teeth
8.	Compared to no-prep, prepping allows:
	a.		total control over the dimensions of the veneers
	b.		gingival contouring
	c.		an ideal emergence profile
	d.		all of the above
9.	The proposed edge of the veneer margin to the crest of the bone should be:
	a.		exactly 2.7 mm of space
	b.		about 2.8 mm of space
	c.		not more than 2.9 mm of space
	d.		exactly 3.0 mm of space
10.	Tooth preparation for the conventional prep technique may involve:
	a.		the use of depth cuts (e.g., using a three-barrel diamond) on the facial surfaces of the teeth
	b.		1.5 mm depth cuts on incisal edges
	c.		a 1.5 mm reduction of buccal cusps
	d.		all of the above
11.	After gross preparation:
	a.		a double-zero cord may be used to pack around teeth
	b.		the packing cord just goes from papilla, around the facial, to the opposite papilla
	c.		packing on the lingual is not required because margins stop well above the tissue
	d.		all of the above
12.	About bleaching lower teeth to match upper veneers, patients may consider that:
	a.		you see a person’s upper teeth when they smile
	b.		you see a person’s lower anterior teeth when they talk
	c.		rarely do you see a person’s upper and lower teeth at the same time
	d.		all of the above
13.	When reducing a tooth’s facial aspect:
	a.		the same three planes on the virgin tooth should be maintained
	b.		adequate reduction helps prevent that “buck look”
	c.		facial reduction of 0.5mm for the pressed ceramic (IPS Empress®) veneers was achieved
	d.		all of the above
14.	The use of a No-Prep Veneer technique is NEVER:
	a.		always right
	b.		always wrong
	c.		all of the above
	d.		none of the above
15.	A gingival veneer margin:
	a.		is never supra-gingival for a no-prep case
	b.		is never supra-gingival for a conventionally prepped case
	c.		can always be easily achieved subgingivally without packing cord
	d.		none of the above
16.	When providing a bite registration for the lab, which is NOT correct:
	a.		only the prepared and opposing incisal edges are required
	b.		the other material, e.g., soft tissue part of the prep next to the gingival, should be cut away
	c.		a putty/wash impression technique is often used for bites
	d.		recording more than the incisal edges of the prepared and opposing teeth will be an interference
17.	When making temporaries:
	a.		a highly detailed putty/wash impression of a wax-up can be used to make bis-acryl provisionals
	b.		defining the sulcus area of a diagnostic wax-up helps stop temporary material and reduces finishing
	c.		a bleaching-shade bis-acryl helps show what to expect if patients insist on “really white” teeth
	d.		all of the above
18.	The finishing of the placed veneers may involve the following:
	a.		the use of Brownie® wheels and a disposable scalpel on facial surfaces
	b.		checking alignment with orthodontic archwire and correcting the arch form prior to preparation
	c.		“instant orthodontics” cannot be done unless the laboratory technician is given enough room
	d.		all of the above
19.	Pre-preparation planning may involve consideration of the following:
	a.		correcting alignment problems by removing enamel and adding composite prior to preparation
	b.		1.5 mm depth cuts on incisal edges
	c.		a 1.5 mm reduction of buccal cusps
	d.		all of the above
20.	Use of depth cuts may involve the use of all or some of the following instruments:
	a.		round and barrel-shaped diamond burs
	b.		a safe-sided serrated metal strip or metal saw
	c.		a Brownie® wheel
	d.		none of he above
