What do you do after you the apex locator finds the apex
Either take a radiograph or irrigate – fuck if we know
Where does the orifice opener go to?
Mid 1/3 and coronal 1/3 (guess you were able to click 2, but it didn’t say select all so watch out for that)

0.04
What is the taper for CLC?
0.02
Which phase of gutta percha is used for CLC?
Beta phase
below 42 C
What do you use for scouting?
10 file
What is considered a reciprocal file?
Wave one gold
What are the shaping principles, all of these except?
a. Constantly tapering funnel
b. Adequate deep space
c. Retention of apical constriction
d. all canals need to be widened greater than a 40 file
d. all canals need to be widened greater than a 40 file
Colors of the file
10 – purple, #15 – white, #30 – blue, #35 – green
Minimal curvature of the mesial root of mandibular molar, what size do you use?
30-35
Matching of pure endo, etc… with their definitions
easy
What file do you use for a glide path?
15 hand file
CLC where is the gutta percha placed using finger spreader?
2mm (I guess)
“Finger spreader placed ideally 6-2mm of the prepared length”
Increase in file size = _______ flexibility and ______ stiffness
Decrease
increase
What do you place on a premolar after RCT?
Cast crown
What technique do you use for the master cone for hydraulic?
Double coat
What anatomical structure is generally mis-identified as a LEO?
Mental foramen
Case base question
Refer to endo
Case base question
Refer to endo
What is the sensibility test that differentiates endo and perio?
Cold/ept
Case question regarding patient would had negative results for testing and had swelling
AAA
Same case questions as above and asked about the pulp
Necrotic
T/F: Ricucci says that’s you can remove extraradicular biolfim by disinfecting the canal
False
Which of the following is not a type of communication pathway
Internal root resorption
T/F: During surgical intervention you must do apical curettage followed by apical resection and retrofill
True
What canal would you miss if you didn’t extend it correctly in an incisor? (must extend incisal and cervically)
Lingual canal
What would you do for tooth #5 if a straight angle shot was taken and there is a PA lesion on radiograph, but all testing was WNL
a. Take another radiograph from a different angle
b. Call in pathology
c. Complete the RCT

What is a reason for retreatment?
a. Missed canal
b. No symptoms present
a. Missed canal
True/false
BC Sealer should be easy to remove after it is set
according to Dr. Google- false
T/F: if pt is having continued symptoms, obturate canal to finish treatment so symptoms will subside
False
