This video talks about the different instruments that are required for a proper access cavity preparation in a root canal procedure.
Endodontic treatment can be divided into 3 main steps,
1) Access cavity preparation
2) Shaping and cleaning of the root canal
3) Obturation
However, an ideal access cavity forms the foundation of root canal procedure and it allows a straight line entry into canal orifices. On the other hand, an improperly prepared access cavity can interfere with the instrumentation, disinfection and obturation, therefore affecting prognosis of the endodontic treatment. Watch this video to know about the instruments and burs used for access cavity preparation….at what step to use each of them, how to use them and their advantages in that particular step.
For simplicity, instruments used in access cavity preparation have been divided into 4 categories
Access opening
Pulp extirpation
Orifice location
Orifice enlargement / Coronal Flaring
The instruments discussed according to the sequence are
1) Round Bur
2) Safe End Bur / Endo - Z Bur
3) Endo Access Bur
4) Endodontic spoon excavator
5) Barbed Broach
6) DG-16 explorer
7) Ultrasonic Endotips
8) Round Carbide Burs with Long Shafts. Eg. Munce Discovery Burs, Drux Burs
9) Gates Glidden Drills
10) Orifice Openers.
Eg. Sx rotary files
