,Four well designed studies showed articaine to be more successful in achieving adequate anesthesia
than lidocaine in mandibular teeth. One theory is that articaine is more effective due to its higher
concentration.

What is the dominant color of an object?
A. Chroma
B. Hue
C. Value
D. Color - CORRECT ANSWER (B) Hue
,Hue is the dominant color of an object for example red, green, and blue. Value is also known as the
gray scale. Value increases toward the high end (lighter) and decreases toward the lower end (darker).
Chroma is the degree of saturation of a particular hue. For example, red can vary from 'scarlet' to light
pink where scarlet has a high saturation and pink has a low saturation.

B. Tensile strength
C. Shear strength
D. Compressive strength - CORRECT ANSWER Correct Answer: (A) Yield strengthDefinition
of yield strength: the stress which a test specimen exhibits a specific amount of plastic strain.
Under clinical conditions, composite resins can suffer surface wear and degradation by coming in

B. Compressive strength is between 180 and 300 MPa.
C. Flexural strength is between 20 and 40 MPa.

Dentinogenesis imperfecta is characterized radiographically by:
A. enamel hyperplasia.
B. unusually long and pointed roots.
C. a thickened periodontal ligament space.
D. total or partial root canal obliteration. - CORRECT ANSWER (D) total or partial root canal
obliteration.
Dentinogenesis imperfecta has been divided into three types. In type I or syndrome-associated, the
dentin abnormality (opalescent teeth) occurs in patients with concurrent osteogenesis imperfect and
primary teeth are more severely affected than permanent teeth. In type II, patients have only dental
abnormalities (isolated, hereditary opalescent teeth) and no bone disease. In type III, only dental
defects (isolated opalescent teeth and Brandywine isolate) occur.
