Is EndoSequence BC Sealer Expensive? (Friday Questions)

December 20, 2014 6:13 pm Published by

The cost of EndoSequence BC Sealer per syringe is only meaningful if we attempt to find out how many physical root canals can be done using its content. In this video, Dr. Nasseh does a practical bench-top experiement using the Basic Hydraulic Condensation Technique (Injecting outside the mouth on a paper pad and transferring the sealer in the root canal using a file and the master gutta percha cone (the traditional technique). The Advanced Technique, which involves direct injection of the sealer inside the root canal and requires a microscope for adequate sealer placement and control is not used here. The Basic Technique does not require you to change the dispensing tip between patients since the tip does not come in contact with the patient and the material does not set in the tip unless not used for several days. The Advanced Technique is more efficient, requires a microscope, but wastes a very small amount of sealer in the dispensing tip because the tip has to be changed between each patient (comes in contact with the tooth.)

In this video, Dr. Nasseh shows how many applications of the Basic Sealer you can get from a single syringe. To calculate cost of the sealer per canal, divide your purchase cost by the number 57 (The number of applications present in each tube based on this bench top experiment) and you will get the cost per application.…
