Of the following, what is the BEST treatment for a Class IV fracture of a lateral incisor with no pulp exposure and otherwise healthy teeth?

65% - 69%
Of the following, which class of composites demonstrates the BEST physical and optical properties for both anterior and posterior composite restorations?
In comparing the use of electrosurgery lasers, and scalpels to achieve the desired gingival modification around implants:
scalpels are safe, provide excellent hemostasis, and the least amount of gingival recession following surgery.
Which of the following can aid in reliably achieving centric relation?
A properly shade matched porcelain veneer will often appear dark immediately after the seat appointment due to which of the following?
Dehydration of the adjacent teeth
The avoidance of open cervical embrasures can BEST be achieved by placing the interproximal contact points relative to the interproximal:
The "white line" which shows up occasionally when finishing a composite restoration between the restoration and tooth structure is caused by what?
Polymerization shrinkage, which tears the composite at the margin with the tooth
Which of the following may adversely affect bond strengths and result in increased microleakage?

Minimal chamfer finish line
When utilizing an acellular dermal matrix as a graft material in covering exposed root surfaces, which of the following is BEST to completely cover the area?
A coronally positioned flap
The optimal preparation for posterior all-ceramic restorations is a:
rounded 90-degree shoulder.
The general guideline for minimal ferrule design is:
1.0 mm -2.0 mm
How can the undesirable effects of polymerization shrinkage be managed?
By reducing the number of increments of composites
When considering ceramics for posterior restorations, one should recognize that ceramics are stronger when?
Under compressive stress, but weaker under tensile and shear stress
During proper articulation of the "S" sound, which of the following BEST describes the relationship of the incisal edges of the maxillary and mandibular incisors for the majority of patients?
Maxillary and mandibular incisors closely approximate each other
What feature of dentin hybridization makes it useful for resin bonding?
It does not affect the dentinal tubules
A white opacity near the incisal one-third of a permanent incisor is MOST likely the result of what?
Trauma or infection of the patient's deciduous incisor

Superior to the final desired gingival zenith
What does platform switching describe?
The bone level of the adjacent teeth
The long axis of a tooth inclines distally in the inciso-apical direction. Which of the following is also true?
Inclination increases from incisors to cuspids
When a connective tissue graft is placed over an anterior implant site, it is BEST to:
bond a temporary tooth to the adjacent teeth to keep pressure off the site.
The process of directing occlusal forces through the long axis of the teeth is known as axial:
