1.Which ,if left untreated,is most likely to result in a periaplical lesion?
a.internal resorbt.
b.reversible pulpitis
c.ac.suppurative pulpitis
d.ch.hyperplastic pulpitis
e.diffuse calcification of the pulp

2.An acperiap. abscess originating from a mand. third molar generally point and drains in the:
a.submandibular space
b.pterygomandibular space
c.bucccal vestibule
d.buccal space

3.Do you know the most undesirable propertie of sodiun chloride?

4.What is the most likely direction to perforate when you prepare the root canal for central maxilar incisives:mesial, distal, labial or lingual?

5.Who are more:the mand.first molar with 3 or with 4 canals?Give percents for sustaining the statement.

6.Where the apical foramen leaves the root: at the anatomical apex or away from it?

1.Which ,if left untreated,is most likely to result in a periaplical lesion?
a.internal resorbt.
b.reversible pulpitis
c.ac.suppurative pulpitis
d.ch.hyperplastic pulpitis
e.diffuse calcification of the pulp

The 2 more consistent answers of this question are:
b.reversible pulpitis = symptomatic reversible pulpitis
c.ac.suppurative pulpitis = asymptomatic reversible pulpitis
In reference to Cohen: Pathways of the pulp 9th edition #36: ''typically, when a sypmptomatic irreveresible pulpitis remains utreated, the tooth eventually succomb to necrosis''

2.An acperiap. abscess originating from a mand. third molar generally point and drains in the:
a.submandibular space
b.pterygomandibular space
c.bucccal vestibule
d.buccal space


3.Do you know the most undesirable propertie of sodiun chloride?Bitter taste?

4.What is the most likely direction to perforate when you prepare the root canal for central maxilar incisives:mesial, distal, labial or lingual?

In reference to Cohen: Pathways of the pulp: '' The lingual shoulder prevents direct access to the root canal and deflects files labially often resulting in a ledge or perforation''

5.Who are more:the mand.first molar with 3 or with 4 canals?Give percents for sustaining the statement.
2 mesial canals (mesiobuccal and mesiolingual) : 59%, one distal canal: 85%

6.Where the apical foramen leaves the root: at the anatomical apex or away from it?I didn't understand the question: are you talking about the vascular bundle
