Needle that can reliably perform the iNP method developed by a specialist
Summary of Product Characteristics
The tapered needle is designed to maintain fine but sufficient suction. Soft processing makes it possible to insert the needle into more complex root canals and bend it freely so that the iNP method can be used effectively.
Feature 1. Designed for effective root canal irrigation

・Fine tip can handle narrower root canals
・Broad base makes for greater irrigation volume

Feature 2. Flexible and can be bent to various shapes
Feature 3. Can be used effectively in the iNP method
What is the iNP method?
・It is a method for cleaning out root canals in which the irrigation solution is delivered at the crown side and aspirated at the root apex side.
・In this method, there is less leakage of irrigation solution and less influence of air bubbles, such as in vapor lock*.

Air bubbles in the solution during irrigation significantly interfere with the cleaning effect.
Effect of iNP method
Provided by Yoshioka Dental Office
With the iNP method, there is less leakage of irrigation solution from the apical foramen, which makes it possible to clean to the apical foramen.
Instructions for Use
Inject the irrigation solution from the crown side and aspirate out
Aspiration is performed while the irrigation solution is being injected.
Insert needle into apical foramen
Connect the needle to a syringe or other device
The needle's fine tip makes it possible to insert it close to the apical foramen.
