Lecture 1: Working Length & Access Flashcards
When, why, & how to refer your potential problems describes:
Case selection
Most non-complicated cases follow:
one basic RCT technique
LEO:
lesion of endodontic origin
What are our three objectives with endo cases?
- correctly DIAGNOSE disease as LEO
- PERFORM quality NS endodontic therapy
- RESTORE & DOCUMENT healed outcome
What will cause your endodontic treatment to fracture and fail?
lack of placing mandatory crown
Endo treatment is considered an extreme service to the patient as we:
- relieve acute pain
- retain otherwise lost natural tooth
More points are lost in lab to ____ than anything else.
poor access
Most failures on WREBs & ADEC are due to:
poor access
What is the first step in access procedure?
Outline (draw outline form on tooth)
The shape of the outline form of the tooth is dependent on:
anatomy of the pulp chamber
After drawing the outline form on the tooth, what step is next?
create outline form just through the enamel with number 2 round or 330 bur on high speed
What layer should be drilled through when creating the outline form?
just through the enamel
What burs and what speed may be used when creating the outline form?
2 round bur or #330 on high speed
When creating the outline form, the bur is somewhat ____ to the ____ surface of the tooth
perpendicular; lingual
When creating the outline form, its important to stay ___ at this point, just through the enamel at less than ____mm
shallow; 1mm
after the outline form is created, the next step to the access procedure is:
penetration
During the penetration step of the access procedure, penetrate the pulp chamber roof with ____ approaching ____ in center of outline form.
bur angled; parallel to long axis of root
During the penetration step of access procedure, penetration the ___ with the bur angled approaching parallel to long axis of the root in the ___ of outline form.
pulp chamber roof; center
During the penetration step of the access procedure you should reach the pulp in most cases by:
7mm
(if not ask for help- never go beyond 7mm)
During the penetration step of the access procedure, how should you confirm pulp canal entry?
with endodontic explorer; DG16 (push)
To confirm pulp canal entry, during the penetration step of the access procedure, you should NEVER look for canals with:
a bur
What step of access procedure follows penetration?
un-roofing
Un-roof pulp chamber with:
brushing out-strokes
When un-roofing the pulp chamber with brushing out-strokes, be careful not to:
gouge axial walls
