anteriors: canine to canine
or clamp on one premolar
rubber damn with peds? endo?
peds: only necessary teeth
endo: single tooth
absorbents:
cotton rolls- vestibules
dry shield- protect cheek

bite block
anterior lip retractors
ADA caries classification
- sound
- initial
- moderate
- advance
enamel layers E1 and E2=
remineralize
what is the treatment planning consideration when the caries extends only to the first third of dentin
restore surgically or attempt to remineralize
what is the treatment planning when the caries extends to the middle third of dentin or the D2 (dentin second layer)?
restore surgically
what is the treatment planning when the caries extend to the D3 (dentin third layer)?
restore surgically, prepare for possible root canal or pulp capping; close to pulp
why flare buccal >100 and lingual >90 on class II composite prep?
optimal for bonding and enamel rods exposed
once the ideal outline form is achieved for class II prep:
remove caries with spoon excavator and use round bur on slow speed handpiece
in class II prep, if extra retention grooves are needed, where can they be placed
in the buccal-axial line angles
[IT IS ENTIRELY IN DENTIN]
for composite class II restoration, began placing material in____ of prep.
place ____. cure:

incrementally
cure each increment for 20 seconds
where is composite seal most important
at gingiva
[use flowable here]
form final anatomy (before/after) final cure
before
