|
spoon excavator.
slow speed round bur at low speed. remove stain at DEJ leave stained but hard dentin on pulpal wall and axial wall (Class II) |
|
|
When should you use a sedative base and why?
|
when depth of prep is .5m or more.
promotes making of secondary dentin, seals dentinal tubules from chemical and bacterial irritants.. minimizes pressure of condensation on pulp tissue. insulation of pulp from thermal irritation. |
|

AKA) CaOH
bacteriacidal=pH of 11 forms repartive dentin |
|
|
What is the process following indirect(with left caries vs with no left caries) pulp capping vs Direct?
|
Direct: stop bleeding, put dycal, then GI.
Indirect with complete caries removal: place GI liner. Indirect leaving some caires: dycal then GI |
|
|
