Study Notes

Root Canal Anatomy

The chapter covers root canal components and morphology, root canal configuration systems, and root canal anomalies and embryologic malformations.

Learning Objectives

Recognize errors that may cause difficulties or failures in root canal treatment due to lack of knowledge of pulp anatomy.
List techniques that help determine the type of root canal system.
Draw the eight most common canal types (Vertucci’s I to VIII).
Understand the two most commonly used classification systems (Vertucci and Weine) for root canal system and their limitations.

Root Canal Components and Morphology

The root canal system can be divided into two parts: the pulp chamber and the root canal space.
The pulp chamber is a cavity normally situated in the center of the crown and resembles the shape of the crown surface.
The root canal space is found inside the radicular portion of the tooth.

Isthmus

An isthmus is a narrow, ribbon-shaped communication between two root canals that may contain vital tissue, necrotic pulp, biofilms, or residual filling material.
Isthmuses may present with different configurations and their prevalence is dependent on the type of teeth.
Isthmuses can be commonly observed after root-end resection in cases referred for apicoectomy treatment.

Clinical Significance

Unfilled isthmuses can be a limitation in nonsurgical treatment.
Chemical agents that have the ability to dissolve organic tissue at fine levels can be used to surpass these limitations, often associated with ultrasonic activation.
