Obturation Techniques for Pulpectomy
Pulpectomy is the removal of the inner contents of the pulp along with the roof so that to gain access to root canals that are enlarged, debrided and disinfected. This can be done using various techniques. The obturation techniques for pulpectomy are discussed below in this article. Let us examine them.
Obturation techniques for PulpectomySeveral techniques have been used for the filling of materials into the deciduous teeth canals.
- 1. The primary teeth with their larger canals may be filled with a thin mix coating on the walls of the root canal with the help of a reamer in a anti-clock wise direction while taking it out slowly followed by the placement of the thicker mix which is then pushed manually.
- 2. Pastes can also be filled by means of a Lentulo spiral mounted on the micro motor hand piece. The direction of rotation needs to be checked for the material to properly flow into the canal.
- 3. The endodotic pressure syringe is also effective for placing the ZEO into the canals. The Vitapex system also uses a syringe with the material in it. The syringe is introduced up to 1/5th the distance from the apex of the canal and the material is slowly injected as the syringe is withdrawn from the canal.
