what is the name given to the branches that connect between main root canals

isthmus
Vertucci’s canal configurations classifies canals.
which classification is given to a tooth with one root canal
type 1

Vertucci’s canal configurations classifies canals.
which classification is given to a tooth where two root canals converge in to one
type 2

Vertucci’s canal configurations classifies canals.
which classification is given to a tooth where one root canal diverges in to two canals and then rejoins to form one canal
type 3

Vertucci’s canal configurations classifies canals.
which classification is given to a tooth where there is two root canals apically
type 4

Vertucci’s canal configurations classifies canals.
which classification is given to a tooth with one root canal, whichdiverges in two roots apically
type 5

Vertucci’s canal configurations classifies canals.
which classification is given to a tooth with two root canals, chich crossover form one root, and then split to form two root canals at the apex.
type 6

Vertucci’s canal configurations classifies canals.
which classification is given to a tooth with one root canal, diverges to form two root canals, then crosses over to form root, then diverges to form two roots at the apex
type 7

Vertucci’s canal configurations classifies canals.
which classification is given to a tooth with three root canals
type 8

whats the difference between an accessory canal and a lateral canal
an accessory canal is defined as a fine branch of the pulp canal that diverged at an oblique angle from the main canal to exit into the periodontal ligament space, whilst a lateral canal was defined as a branch diverging at almost right angles from the main canal

accessory canals occur in three distinct patterns in the mandibular first molars.
where is the accessory canal located in this image

accessory canal in the furcation region
it is thought these furcations occur in 13% of cases
accessory canals occur in three distinct patterns in the mandibular first molars.
where is the accessory canal located in this image

lateral canal extends from the coronal third of a major root canal to the furcation region.
this type occuring in 23% of cases
accessory canals occur in three distinct patterns in the mandibular first molars.
where is the accessory canal located in this image

have lateral and furcation canals
10%
the upper right 6, 7 has the potential to have how many canals each
4

what is the genreal rule when dealing with measurements. what is the measurement from the pulpal floor to furcation

3mm

what is the genreal rule when dealing with measurements. what is the measurement of the pulp chamber height in mandibular and maxillary molars

mandibular molars 1.5mm
maxillary molars 2mm

what is the genreal rule when dealing with measurements. what is the measurement from the buccal cusp to pulp chamber roof height

mandibular and maxillary 6mm

maxillary first molars have 3 roots what are there locations
palatal, mesiobuccal and distobuccal

the first mesiobuccal canal i sunder which landmark
usually under the tip of the mesiobuccal cusp

the three canal orifices, located in the maxillary first molars are located in which portion of the tooth
mesial portion of the tooth

what is the name of the canal that diverges then meets the canal again

2nd MB canal of the upper maxillary first molar
the maxillary second molar, commonly has 3 roots and 3 canals (56.9%)
however, sometimes it has three roots and 4 canals (22.7%) where is the 4th canal located?

4th canal represents a 2nd mesiobuccal canal
the maxillary second molar very rarely has 4 roots with 4 canals (1.4%)
where would the 4th root be located
palatally
how many roots do mandibular first molars have
2 well fomed roots
