6 criteria to consider when choosing new or old endodontic file systems 

A. Material used 

The industry standard when it comes to rotary endo files is either stainless steel or  NiTI (nickel titanium). These are strong, offer degrees of flexibility and can be cost-effective depending on the vendor you choose. 

Different vendors have also developed additional technologies to enhance the strength and flexibility of the NiTi files they develop. Understanding the efficacy of “heat-treated”, “gold”, and other material types will also help determine the best option for your practice

B. Resistance to cyclic fatigue that indicates strength and durability

With rotary files, you want something that has the strength and durability to withstand different situations. Resistance to cyclic fatigue can give you a precise measure of how reliable the files can be relative to other brands. The greater the resistance, the better the quality of files it is.

C. Vendor advertised strengths give you an idea of what the files can do well

All endo file systems will be developed and marketed with a different angle in mind. Understand whether files are being marketed on the competitive pricing they offer, superior quality, or ability to interact with other systems (i.e is it a closed or open system?)

D. Technique required & compatibility helps you determine how steep of a learning curve there is

It’s one thing to switch or start using a brand new system. It’s quite another to learn a whole new technique. The costs for this can easily start piling up with multiple CE courses, and other expenses you would not have initially accounted for. A sign of a good endo file system is its compatibility with techniques that are mainstream and currently popular. This can ensure the easiest transition for you without having to worry about picking up a new technique.

E. Price has to be reasonable and must justify itself in relation to ROI

Quality, technique, and effectiveness are important considerations. Yet, if you can get all those at a price that works for your practice, then you have hit the jackpot. It’s no secret that dentists are now much more in tune with their financial positions and will be looking for any opportunity to save and cut costs without risking or compromising on quality. Endodontic file systems can be a great source of savings if you look in the right places

F. Service when it comes to technical and logistical issues is important for your peace of mind and confidence in the files you use

All vendors offer some kind of client support. Whether it is through your dealer or directly from the manufacturer, understand any warranties, training, and in person/over-the-phone/online support that is offered. A company that invests in you through client support mechanisms is a sign that they are willing to do what is in your and the patients’ best interests.

Conclusion

So there you have it. These 6 criteria, when taken into account, will help you make the best decision about the endo files you want to start (or continue) using into the long term. It’s not just about the brand and what everyone around you uses. What should be clear to you by now is that each file system has its benefits….but also drawbacks. Read between the lines and you will know exactly which file system will truly fit your style best. At the end of the day, it’s about your professional and financial growth.
