pediatric restorations Flashcards
max dosage of local anesthetic
4.4 mg/kg
absolute max dosage
300 mg
how to determine max allowable carpules
- determine weight in kg by dividing by 2.2
- multiply kg by 4.4 mg/kg for max mg dosage
- multiply % LA x 10 x size (usually 1.8 mL) to get mg/carpule
- divide max mg dosage by # mg/carpule
benefits of rubber dam
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
benefits of slit dam technique
offers slightly less isolation but easier to place
t/f. for pedo pts, you should place the rubber dam and frame as a unit
yes
what is the most common mistake in restoring primary teeth
over extension of prep
advantages of amalgam
durability, strength
moisture control
less technique sensitive
disadvantages of amalgam
extansive removal of tooth structure
isthmus fracture is common with shallow preps
advantages of compomer
good aesthetics
some fluoride release
excellent handling
wears similarly to primary teeth
disadvantages to compomer
technique sensitive
need for complete moisture control
advantages to composite
good aesthetics
more conservative prep
good wear resistance
disadvantages for composite
technique sensitive
need for complete moisture control
advantages to glass ionomer
good aesthetics
fluoride release
complete moisture control isnt critical
fast and easy to place
disadvantages of class ionomer
poor occlusal wear
difference bt Fuji IX GP EXTRA and Fuji II
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
types of GI restorative materials
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)
ideal pulpal depth for class 1 amalgam prep
1 - 1.25mm
what type of restoration would you do if the prox caries have broken through the marginal ridge
composite or SSC
when proximal caries is visible clinically, what types of material are indicated
compomer, composite, GI, or SSC
differences between prep for amalgam or resin
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
2 guidelines for composite class II preps
external outline form is determined by caries and anatomy of tooth
ideal pulpal depth is 1 - 1.25mm
t/f in class V restorations, a bevel is placed around the entire cavosurface margin if composite is used
true.
indications for SSC
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
