Handbook 4-6

Question 1

What is the length of time of application of APF 1.23% fluoride foam?

Answer 1

There is a benefit of APF foam (1.23 percent fluoride) application twice per year for 4 minutes for caries prevention for 0-6 year olds (no benefit after age 6)

Question 2

How much fluoride is in a pea size amount? Hint: 3-6 yo

Answer 2

0.25 mg (Note: the recommended professionally applied fluoride treatment for children under the age of six with ECC is sodium fluoride varnish NaFV 22,500 F)

Question 3

Best way to reduce radiation?

Answer 3

Faster film speeds have contributed most significantly to the reduction in radiation to the patient

Question 4

Microbial risk markers for ECC?

Answer 4

S. mutans and Lactobacillus

Note: S. sobrinus is also involved in the cariogenic process

Question 5

A decayed, missing, or filled score of greater than or equal to 4 (age 3), greater than or equal to five (age 4), or greater than or equal to six (age 5) surfaces

Answer 5

S-ECC Age 3-5

Question 6

BQ: What % of children have calculus?

Answer 6

60% of teenagers have gingival bleeding on probing

10% have calculus

Question 7

Define ECC

Answer 7

The disease of ECC is the presence of one or more decayed (noncavitated or cavitated), missing (due to caries), or filled tooth surfaces in any primary tooth in a child under the age of 71 months

Question 8

How much fluoride is in a smear layer or rice size amount? (hint: 0-3 yo)

Answer 8

0.1 mg

Question 9

Adolescents before eruption of third molars, frequency of bite wings: low risk

Answer 9

q18-36 months

Question 10

Define severe ECC

Answer 10

Younger than 3: any sign of smooth surface caries

Age 3-5: one + cavitated, missing (due to caries), or filled smooth surfaces in DEFG

Age3-5: a decayed, missing, or filled score of greater than or equal to four (age 3), greater than or equal to give (age 4), or greater than or equal to six (age 5) surfaces

Question 11

T/F: APF 1.23% foam. The trays should be about 1/3 to 1/2 full for gel and full (level with the edge) for foam. Usually both upper and lower trays are inserted at once to complete the topical fluoride treatment in one 4-minute application

Answer 11

True

Question 12

S-ECC: Younger than 3

Answer 12

any sign of smooth -surface caries

Question 13

The recommended professionally applied fluoride treatment for children under the age of six with ECC is sodium fluoride varnish

Answer 13

NaFV 22,500 ppm F

Question 14

What is the length of time of application of fluoride gels?

Answer 14

4 minutes

Question 15

one+cavitated, missing (due to caries), or filled smooth surfaces in DEFG

Answer 15

S-ECC Age 3-5

Question 16

What immunoglobulin is lower in tobacco users?

Answer 16

Lower levels of IgG2

Question 17

What is the location of minimal exposure to the operator during radiographs?

Answer 17

45 degrees from the primary beam as it exits the patient, at least 2m away from the tube head

Question 18

T/F: Rectangular collimation also reduces the radiation to the patient by a factor of 4-5

Answer 18

True

Question 19

BQ: What immunoglobulins are elevated in NUG?

Answer 19

Compared to the gingivitis and healthy groups, the ANUG groups exhibited significantly higher IgG and IgM titers to intermediate-sized spirochetes and higher IgG titers to bacteroides melaninogenicus subsp intermedius (Note: Tobacco users have Lower levels of IgG2)

Question 20

How often do you take radiographs for a low risk child with primary or transitional dentition, bite wing exposure?

Answer 20

q 12-24 months

Question 21

BQ: What percent of teenagers have bleeding on probing?

Answer 21

60% of teenagers have bleeding on probing

Question 22

Adolescents before eruption of third molars, frequency of bite wings: high risk

Answer 22

q6-12 months
