Study Notes

Isolation in Endodontic Procedures

The primary advantage of using isolation during endodontic procedures is to prevent contamination and ensure asepsis.

Rubber Dam (RD)

The recommended thickness for rubber dam (RD) is 0.06 mm.
When using a non-wing clamp, the rubber dam (RD) should be placed first, followed by the clamp.
If there is not much tooth structure to clamp, a build-up may be needed before placing a rubber dam (RD).

Tooth Anatomy

The pulp is generally located in the center of the tooth, between the enamel and dentin.

Access Openings

It is important to consider the morphology of each individual tooth group when determining access openings for endodontic procedures.
The recommended shape to access preps for a normal tooth with radiographic evidence of pulp chamber and canal space is a triangular or oval shape.

Isolation During Endodontic Procedures

Using a rubber dam (RD) serves as a barrier against saliva, bacteria, and debris during endodontic procedures.
One of the benefits of using rubber dam isolation during endodontic procedures is to improve visibility and control.

Endodontic Procedures

Convenience Form is used to facilitate the development of an aseptic environment prior to entering the pulp chamber or radicular space.
Failure to clean the periphery is a common error during endodontic procedures.
The C-shape canal morphology is common in the Asian population.

Pre-Procedure Preparation

A rubber dam (RD) must be placed before files and broaches are used in endodontic procedures.
A explorer is used to detect canal orifice or dislodge calcifications during endodontic procedures.
Case difficulty should be assessed using pre-op images to determine the complexity of the procedure.

Challenges During Endodontic Procedures

Extensive foundations in crowns can hinder visibility during access in endodontic procedures.
