28
Total removal of all pulp canal to terminal end:
Pulpectomy
29
T/F: Long needle for Now Gates is required
False
30
T/F: #4 bur on mandibular incisors
False- #2 bur is use on anterior teeth
31
Maxillary premolar access shape:
Oval with MD buccal-palatal
32
All of the following are VRF except: a- J shape b- drop pocket c- elevated temp d- previously treated successful RCT
c- elevated temp
33
% of treatments that are left in RCT:
30%
34
T/F: Use bur to find canal
False
35
NaOCl breaks down and becomes inactive within:
3-5 min
36
Dentist removed nerve and put temporary material in the tooth, what is the diagnosis:
Previously initiated treatment
37
Previous dentist removed nerve and tooth is not responsive to sensitivity tests. No PARL. Periapical diagnosis:
Healthy tissue
38
What is used to ensure a seal is placed in addition to a rubber dam:
Oraseal
39
DST is indicative of:
Chronic apical abscess (CAA)
40
Pimple on gums is indicative of:
Chronical apical abscess (CAA)
41

True
43

There is a J shaped lesion & a single mm perio pocket drop off on previously treated RCT, with this information it is safe to assume it is VRF:
False- you have to surgically expose

DON'T let needle bind
66
