Table 1 Vertucci’s Canal configuration classification (1984).
Canal configuration | Description |
|---|---|
Type I | A single canal from the pulp chamber to the apex |
Type II | Two separate canals leaving the pulp chamber but joining short of the apex to form one canal |
Type III | One canal leaving the pulp chamber, dividing into two within the body of the root and merging again to exit as one canal |
Type IV | Two separate and distinct canals from the pulp chamber to the apex |
Type V | Single canal leaving the pulp chamber and dividing short of the apex into two separate and distinct canals with separate apical foramen |
Type VI | Two separate canals leaving the pulp chamber, merging in the body of the root and redividing into two distinct canals short of the apex |
Type VII | One canal leaving the pulp chamber, dividing then rejoining within the body of the root, and finally redividing into two separate canals short of the apex |
Type VIII | Three separate and distinct canals from pulp chamber to the root apex |
Additional type 3 − 1 | Three separate canals leaving the pulp chamber but joining short of the apex to form one canal |
