Root Canal Anatomy Part 1

What is success in endodontics

A healthy, functional tooth in a healthy periapical environnent.

The main purpose of Endodontics

Treat the interior of the tooth, specifically the pulp and root canals, to save the teeth

Endodontic objective involves removing what

infected, inflamed, or damaged pulp tissue

Root Canal types

Abrupt deviation in the long axis of the crown or root

Dilaceration

Dilaceration arises from

trauma during odontogenesis

Narrow ribbon-shaped connection between two canals in the same root containingg pulp

Isthmus

Weine 1

Weine 2

Weine 3

Weine 4

What Weine and Vertucci describe the same anatomy

1. Weine Type III

2. Vertucci Type IV

Narrowest part of the root canal system

Apical constriction

Apical constriction location

Near anatomic apex

Apical constriction serves as a

Natural stop during cleaning and shaping

Burch and Hulen say that 92% of major foramina deviate from the anatomic apex by an average of ______ mm

0.59 mm

Kuttler says that the CDJ is located _____-____ mm from the radiogrpahic apex

0.50-0.65 mm

CDJ location from the radiogrpahic apex increases with

1. age

2. cemental deposition

Rationale for obturating is _____-____ mm short of radiographic apex

0.5-1 mm
