Safety as a Prime Consideration in Root Canal Procedures


Dr Shahab Mirjafari, owner of Excel Dental Care, explains why Dentsply Sirona’s WaveOne® Gold and ProTaper® Next are his endodontic systems of choice.

“Are root canal procedures safe?” is the question many patients ask when they face the prospect of having endodontic treatment. I reassure them by saying that safety is paramount in endodontics and that’s made possible by only using the safest endodontic file systems.

Opinion may vary amongst dentists about what constitutes the safest endodontic file system, but I believe reciprocating systems are the safest and simplest option, making them my preferred choice for routine root canal procedures.

WaveOne® Gold from Dentsply Sirona is my go-to reciprocating system. Thanks to its strength and flexibility I know I can push the file safely to the limit. This allows me to treat patients more quickly, they spend less time in the chair and enables me to ultimately provide single-stage, one-visit, treatment.

Along with the strength and reciprocating action of WaveOne Gold there’s the added benefit of how few files are needed to complete root canal procedures. Using just a one or two file clinical sequence is not only more cost-effective, but also allows for faster shaping and more time for cleaning and irrigation to remove bacteria and tissue debris.

For complex cases with very tight or curved canals I need more file flexibility and that’s when I turn to ProTaper® Next. A rotary file, constructed of M-Wire Nickel Titanium (NiTi), ProTaper Next offers flexibility and strength with a greater resistance to cyclic fatigue, reducing the potential risk of file separation.

Easy canal preparation

The glide path is the starting point for all endodontic shaping procedures, reducing the risk of ledges or deviating away from the canal. To ensure a smooth passage to the end of the canal, especially for very narrow canals, I routinely use ProGlider® or the latest reciprocating WaveOne® Gold Glider.

To identify and maintain the biological length of the root canal system I rely on Dentsply Sirona’s Propex Pixi™ Apex Locator. It uses multi-frequency technology to accurately determine the location of the apical foramen, effectively operating in a wide range of conditions, including dry, wet, infected and bloody canals.

Being a dentist who routinely travels to different practices, I need equipment that can travel with me. The Propex Pixi is lightweight and pocket-sized, making it easy to transport and store away.

The X-Smart IQ™ is my endo motor of choice, specifically designed to handle all Dentsply Sirona rotary and reciprocating file systems. It combines a slim, cordless motor with a rechargeable lithium-ion power supply, all easily controlled from an iPad mini via a dedicated iOS® app using Bluetooth® technology.

Support where it’s needed

Moving on from hand files to rotary endodontics for some dentists can be a big step. Dentsply Sirona’s aim is to boost the confidence level of dentists, especially those less experienced in endodontics, offering not just quality materials and equipment but also education and support.

The Dentsply Sirona Academy London, based at Dentsply Sirona’s UK Headquarters, is used to showcase products and equipment in a clinical setting and allows customer training to take place along with an extensive programme of in-house and third party clinical and technical education courses.

Having been mentored by leading endodontists early in my career, I’m passionate about education and use Dentsply Sirona’s facilities to offer general dentists courses on all aspects of safe root canal procedures and direct restorations.
