Chloroform Dip Technique Is One Of The Methods To Increase Adaptation Of Gutta-percha Master Cone At The End Of Root Canal

The dipping technique is based on gutta-percha’s property of becoming soft when dipped in chloroform.

When softened and forced into the root canal, a guttapercha point may be given the exact three-dimensional form of the root canal space

Introduction

Chloroform dip techniqueThe terminal 3 mm of gutta-percha

master cone is placed in chloroform for 1 second and then compressed in to the

canal

Then after 25 seconds it is emitted, covered with sealer and replaced into the root canal.

Finally, the root canal is obturated using lateral condensation technique

Quality of seal of apical irregularities

Dipping

Apical impression

The Dipping Technique Has Been Advocated By Some For Use Without A Sealer

due to the fact that the surface of a gutta-percha point has a certain stickiness in the softened condition. However, as stressed above, gutta-percha alone cannot seal the root canal. When the solvent has evaporated, the point loses its

stickiness and gaps will develop between the point and the root canal wall. Thus, the use of a sealer is mandatory with all gutta-percha techniques

Unfortunately!

Misconception

Why

To ensure better adaptation of the gutta percha cone, chloroform is used in dip technique .

1 -The cone is dipped in a small amount of chloroform and then fit into the canal .

2-The cone is inserted and removed a few times in order to take an "impression" of the apical portion of the canal.

3 -It is important to remove the excess chloroform by rinsing the cone in alcohol and drying it with an air syringe for a full 30 seconds.

4 -Excessive chloroform present in the gutta percha cone can result in shrinkage of the filling material and loss of gutta percha integrity . And may ba occure irritation to periapical tissue . Finally these problems can affect apical seal
