True
-
NUMBER OF PULP CANALS
Maxillary first premolar
Two Canals
-
NUMBER OF PULP CANALS
Mandibular first premolar
One canal
-
NUMBER OF PULP CANALS
Mandibular third molar
Unpredictable
-
NUMBER OF PULP CANALS

Three Canals
-
Which incisor is most likely to have two pulp canals?
Mandibular lateral
-
Canines usually have how many root canals?
One
-
What does Anoxia mean?
lack of oxygen
-
TRUE OF FALSE
If there is an infection within a tooth, harmful gases can cause the root canal to expand.
- False
- The gases expand but the root canal remains the same size.
-
What does furcation mean?
- The region of division of tooth root.
- It is a bifurcation if there are two roots or a trifurcation if there are three roots.
-
TRUE OR FALSE
Furcations are closer to the CEJ on mandibular molars than on maxillary molars.
TRUE
-
TRUE OR FALSE
All anterior teeth have a ridge-like biting edge.
- FALSE
- Incisors do have an incical ridge, but canines have a cone shaped cusp point.
-
TRUE OR FALSE
A central incisor is better able to resist displacement from forces than a canine.
- False
- Canines have longer roots than central incisors.
-
TRUE OR FALSE
Mandibular incisors show a slight attrition (or wearing down) on the labioincisal surface.
TRUE
-
TRUE OR FALSE
Tertiary anatomy refers to the numerous grooves, pits, and lines that third molars often have.
TRUE
-
TRUE OR FALSE
Because of their longer roots, maxillary lateral incisors have a greater crown-to-root ratio than maxillary centrals.
- FASLE
- They have a lesser crown to root ratio.
-
TRUE OR FALSE
The more posterior a molar is located, the closer together the roots will be.
TRUE
-
TRUE OR FALSE
Maxillary centrals and laterals are wider labiolingually than mesiodistally.
- Fasle
- Mandibular incisors are wider labiolingually.
-
TRUE OR FALSE
The Mandibular Lateral is most likely to have a proximal groove in its root.
TRUE
-
When does the mandibular lateral incisor erupt?
7-8 years
