pediatric restorations

Question 1

max dosage of local anesthetic

Answer 1

4.4 mg/kg

Question 2

absolute max dosage

Answer 2

300 mg

Question 3

how to determine max allowable carpules

Answer 3

1. determine weight in kg by dividing by 2.2
2. multiply kg by 4.4 mg/kg for max mg dosage
3. multiply % LA x 10 x size (usually 1.8 mL) to get mg/carpule
4. divide max mg dosage by # mg/carpule

Question 4

benefits of rubber dam

Answer 4

improves child management
improved cisibility/acess
control of saliva and moisture
decreased operating time
protection of pt
improves N20 inhalation as pt becomes nasal breather
protects from accidental ingestion or aspiration
aseptic field for pulp therapy

Question 5

benefits of slit dam technique

Answer 5

offers slightly less isolation but easier to place

Question 6

t/f. for pedo pts, you should place the rubber dam and frame as a unit

Answer 6

yes

Question 7

what is the most common mistake in restoring primary teeth

Answer 7

over extension of prep

Question 8

advantages of amalgam

Answer 8

durability, strength
moisture control
less technique sensitive

Question 9

disadvantages of amalgam

Answer 9

extansive removal of tooth structure

isthmus fracture is common with shallow preps

Question 10

advantages of compomer

Answer 10

good aesthetics
some fluoride release
excellent handling
wears similarly to primary teeth

Question 11

disadvantages to compomer

Answer 11

technique sensitive

need for complete moisture control

Question 12

advantages to composite

Answer 12

good aesthetics
more conservative prep
good wear resistance

Question 13

disadvantages for composite

Answer 13

technique sensitive

need for complete moisture control

Question 14

advantages to glass ionomer

Answer 14

good aesthetics
fluoride release
complete moisture control isnt critical
fast and easy to place

Question 15

disadvantages of class ionomer

Answer 15

poor occlusal wear

Question 16

difference bt Fuji IX GP EXTRA and Fuji II

Answer 16

Fuji II can be used in class II restorations and as a liner under amalgam or composite, where Fuji IX EXTRA can be used as intermediate endo sealing and restorations

Question 17

types of GI restorative materials

Answer 17

Fuji IX (class I and II), Fuji IX Extra (like Fuji IX, with better aesthetics, faster set time, 6x more fluoride release), Fuji II LC (class V and abfractions)

Question 18

ideal pulpal depth for class 1 amalgam prep

Answer 18

1 - 1.25mm

Question 19

what type of restoration would you do if the prox caries have broken through the marginal ridge

Answer 19

composite or SSC

Question 20

when proximal caries is visible clinically, what types of material are indicated

Answer 20

compomer, composite, GI, or SSC

Question 21

differences between prep for amalgam or resin

Answer 21

resin is..
more conservative regarding ext to occlusal surfaces
bevel of enamel margin (class V)
isolation and moisture controlessential
matrix and wedge placement critical
condensing and cure of resin critical
more time needed to finish

Question 22

2 guidelines for composite class II preps

Answer 22

external outline form is determined by caries and anatomy of tooth
ideal pulpal depth is 1 - 1.25mm

Question 23

t/f in class V restorations, a bevel is placed around the entire cavosurface margin if composite is used

Answer 23

true.

Question 24

indications for SSC

Answer 24

extensive caries
rampant caries/high caries risk
following pulp therapy
teeth with developmental defects
fractured teeth
temp restoration of young perm teeth
multisurface lesions
age
behavior problems
