What is a type II canal?
Two separate canals join at one apical foramina
What is a type III canal?

How many pulp horns do incisors typically have?
- Correlates with 3 facial lobes
How many pulp horns do canines have?
- One functional cusp
Almost all anterior teeth have one root with one canal. What is the most likely exception?
Mandibular incisor may have one lingual and one facial canal (type II or III)
What is the only anterior tooth that may have two roots?
Mandibular canine
T/F: Pulp cavities shrink with age.
TRUE
How many pulp horns do maxillary premolars have?
- Two functional cusps
T/F: Mandibular first premolar will always have two pulp horns.
FALSE. Small lingual cusp may result in only a buccal pulp horn.
How many canals are often found in mandibular premolars?
One root with one canal
Which premolar often has two roots?
Maxillary first. Often has one canal per root.
Do the majority of maxillary second premolars have two canals?
No. 40%
Which root in maxillary molars often has two canals?
Mesiobuccal root
How many orifices are typically in the chamber floor of a maxillary molar?
4
Which root in mandibular molars typically houses two canals?
Mesial root
How many orifices are typically found in the chamber floor of mandibular molars?
3
T/F: Primary teeth have proportionally smaller pulp chamber than secondary teeth?
FALSE.
Primary teeth have larger pulp
What is the term for pulp death?
Necrosis
Where is the bifurcation located in a maxillary first premolar?
