Question 2

What is defined as finger-like depressions created by the etching solution?

A)Tags
B)Tubules
C)Residue
D)Damaged tooth structure

Answer 2

A
Explanation: A)When the resin sealant flows over the prepared surface,it penetrates the finger-like depressions created by the etching solution.The projections of resins in the etched area are called tags.

Question 3

When is the BEST time to place a sealant?

A)Once all the permanent molars have erupted
B)As the permanent dentition erupts
C)When the child begins consuming sugars
D)If the child begins to develop caries

Answer 3

B
Explanation: B)Resin sealants are retained better on recently erupted teeth than on teeth with a more mature surface.They are also retained better on first molars than on second molars,and are better retained on mandibular than on maxillary teeth.

Question 4

Where do the majority of caries occur in the oral cavity?

A)Occlusal surfaces
B)Interproximally
C)Areas of recession
D)Incisal edges

Question 5

Deep,irregular pits and fissures offer a much more favorable surface contour for sealant retention compared with broad,shallow fossae.The deeper fissures protect the resin sealant from the forces occurring as a result of masticatory movements.

A)Both statements are true.
B)Both statements are false.
C)First statement is true,second statement is false.
D)First statement is false,second statement is true.

Question 6

When is a sealant contraindicated?

A)When there is incipient caries on the occlusal surfaces

Question 7

A)3 months
B)6 months
C)1 year

Question 10
