Week 2: Pro Taper Gold and Apex Locators

Question 1

What the basics of ProTaper gold

Answer 1

1. Always ensure the file is rotating before introducing it into the canal
2. Shaping files should be used in a brushing motion
3. Do not force the files into the canal
4. Do not use for more than 3 passes without cleaning debris from the files and irrigating the canal
5. Always create a glide path first using hand files

Question 2

On what stroke do ProTaper gold cut?

Answer 2

They cut on the out stroke

Question 3

When do you need to engage the canal walls when using ProTaper gold?

Answer 3

When light resistance is felt then engage the canal wall and brush out

Question 4

What do we need to do after 3 passes of the ProTaper gold

Answer 4

Need to clean debris from the file and irrigating the canal

Question 5

Before using the ProTaper golds what must we create?

Answer 5

A glide path using hand files

Question 6

List the instrumentation protocol with ProTaper gold

Answer 6

1. Access into the pulp chamber, remove all chamber roof
2. Scout coronal part of canal with size 10 hand file
3. Create a glide path in straight part of the canal to size 15 hand file
4. Create a coronal flare with SX file
5. Scout apical part of canal with size 10 handfile
6. Determine working length
7. Create glide paths up to 15 to fill work length
8. Use S1 and S2 in a brushing motion to length
9. Take F1 into canal with single pass, light apical pressure, multiple passes until WL reached

Question 7

What must you do between each pass

Answer 7

IRRIGATE

Question 8

Which files do we use when scouting the canal and creating a coronal guide path

Answer 8

10 K files
15 K files
Use in a watch winding motion

Question 9

What are we working to when creating coronal glide path

Answer 9

Until light resistance

Question 10

Which files do we use to create a coronal flare?

Answer 10

SX in a brushing motion

Question 11

What are we working to when creating a coronal flare

Answer 11

Distance reached by size 15 k file

Question 12

Which files do we use when we are establishing the working length

Answer 12

10 K files in a watch winding function

Question 13

When creating the apical glide path which files do we use?

Answer 13

15 K files

Question 14

What do we work to when creating an apical glide path

Answer 14

Full working length

Question 15

Which files do we need to use when coronal shape

Answer 15

S1
S2
In a watch brushing motion

Question 16

What do we work to when apical finishing

Answer 16

F1

F3
in multiple passes until WL reached

Question 17

What do we work to when creating an coronal shape

Answer 17

Full working length

Question 18

What do we work to when creating apical finishing

Answer 18

Full working length
