- The second tooth in an equal percentage can have one or two channels (56% to 44%).
- On the lower jaw, the third incisor requires special attention. Almost always it has a single channel, but only in 6% of cases there are two.

In 40% of cases, this tooth, which is similar in length to the first premolar, has one root with a single canal. Two canals may be found in about 58% of cases. 4 The configuration of the two canals may vary with two separate canals and two exits, two canals and one common exit, one canal dividing and having two exits. In one study, 5 it was found that 59% of maxillary second premolars had accessory canals. As with the first maxillary premolar, the apical third of the root may curve quite considerably, mainly to the distal, sometimes buccally. The access cavity is similar to the first premolar.
What is a root canal?
Sadly their work, and many similar publications, have largely been overlooked and dentists still remain obsessed with the concept of a 'root canal', a hollow tube down a root which has to be cleaned and shaped, eventually appearing as a nice white line on the post-operative radiograph. Undergraduate students learn the number of canals in each tooth by rote. However, many teeth have more than one canal, as described in this part. Where two canals exist within the same root, for example the mesial root of a lower molar, lateral communication (anastomosis) in the form of fins or accessory canals, occurs between them. Even roots with a single canal will have lateral and accessory canals leaving the main canal. Unless this concept of an entire root canal system is clearly understood, and a method of cleaning and shaping this system employed to address these anastomoses as well as the main canals, infection will remain in the root canal system, and the treatment may fail.
How many canals does Vertucci 7 have?
The canal configuration of this tooth can be quite complex. Vertucci 7 has shown that the single canal normally found may divide into two canals and two apical foramina in 25% of cases. It is the way in which the second canal branches that can cause difficulty with instrumentation. Occasionally, the canal terminates with an extensive delta, making obturation of the accessory canals even more challenging. As in the upper premolars, the access cavity is oval between the cusp tips.
How many roots does a mesiobuccal have?
This tooth has three roots. The palatal root is the longest, with an average length of 22 mm; the mesiobuccal and distobuccal roots are slightly shorter, at 21 mm average length. The percentage of mesiobuccal roots having two canals reported in the literature has increased steadily as research techniques have developed. In vitro studies have usually reported a higher incidence than in vivo studies. Stropko, reporting an extensive in vivo study, 6 found second canals in 73% of cases before the use of an operating microscope, but 93% following its use. The canals of the mesiobuccal root are often very fine and difficult to negotiate; consequently, more errors in instrumentation occur in this tooth than in almost any other. Anastomosis between these two canals may take the form of narrow canals or wide fins, both almost impossible to instrument. The curvature of the roots can be difficult to visualize from radiographs, and the second mesiobuccal canal is nearly always superimposed on the primary mesiobuccal canal. The palatal root has a tendency to curve towards the buccal and the apparent length on a radiograph will be shorter than its actual length. The access cavity represents the shape of the pulp chamber, enlarged slightly, and flared up on to the mesiobuccal aspect of the occlusal surface to accommodate the angle of instrument approach when working at the back of the mouth.
What is the term for the form of fins or accessory canals?
Where two canals exist within the same root, for example the mesial root of a lower molar, lateral communication (anastomosis) in the form of fins or accessory canals, occurs between them. Even roots with a single canal will have lateral and accessory canals leaving the main canal.
Which canal has the greatest degree of curvature?
The mesiobuccal canal tends to exhibit the greatest degree of curvature. The access cavity once again represents the shape of the pulp chamber, enlarged slightly, and flared up on to the mesiobuccal aspect of the occlusal surface to accommodate the angle of instrument approach when working at the back of the mouth.
What is accessory canal?
The term 'accessory' is usually reserved for the small canals found in the apical few millimetres and forming the apical delta ( Fig. 2 ). Both lateral and accessory canals develop due to a break in 'Hertwig's epithelial root sheath' or, during development, the sheath grows around existing blood vessels.
How many roots does a maxillary premolar have?

Which is bulkier, the lateral or the maxillary incisor?

They themselves are much larger than other teeth, they have more roots and canals. However, this indicator is not constant. It does not mean that the upper and lower incisors have only one channel. In this issue, everything depends on the individual characteristics of the jaw system of man.

Therefore, it is easy to understand how many channels in the tooth with a high potential of chewing load. Their number is much larger than that of representatives of the "biting" group.

Inside each tooth there is a cavity. It contains pulp - a collection of nerves and blood vessels. They are responsible for the continuous feeding of bone formations. If it is removed, the tooth will become dead. Towards the roots, the cavity narrows slightly. This is the tooth channel. It stretches from the top of the root to its very base.
