EXACTTAperH DC

This easy-to-use minimally invasive rotary endodontic fi le system combines unsurpassed flexibility with superior strength for predictable root canal treatments 

During root canal treatments, whether you’re a seasoned endodontist or a general dentist who performs occasional root canals, the fear of file separation and fracture looms large, especially with challenging and curved canals. With this in mind, SS White designed their newest line of minimally invasive endodontic files, EXACTTaperH DC, which offers unmatched strength and fl exibility for efficient, separation-free performance in even the most complex root canal anatomies.

Explaining that the “strength and fl exibility of rotary files” are crucial to successful root canals, Dr. Varo Boyer discovered that “EXACTTaperH DC files are so strong that there is no fear of separation in the canals.” In addition, he said, “The flexibility allows me to navigate the more challenging and curved canals with ease and confidence.” Dr. Boyer praised the “simplified sequence and ease of maneuvering around canals” of this tapered file system, which includes files for accessing, shaping, and fi nishing canals, along with matching gutta-percha and paper points.

After only a few uses of the EXACTTaperH DC files, Dr. Boyer was convinced he could “confi dently navigate tight and curved canals without being afraid of separation or breakage, even of the thinner files.” All in all, he said the system has made him “more confi dent and effi cient with challenging endodontic cases,” while preserving more dentin and tooth structure to ensure tooth longevity. “The strength and flexibility of these fi les shine,” Dr. Boyer decided.

Strength, Flexibility, & Cutting Efficiency

According to SS White, EXACTTaperH DC files are stronger, smaller, and more fl exible than other variable taper files, and they allow stress-free navigation of curves up to 90º while resisting cyclic fatigue. Smaller tapering in the mid and upper portion of each fi le enhances flexibility, improves access, and supports conservative restorative options, while the smaller maximum flute diameter fits to the natural size and shape of the canal.

Calling the file system “very easy to implement,” Dr. Todd Sarubin appreciates the flexibility of the files that move easily through tight canals and successfully clean and open canals for disinfection. He said the glide path files are “very good at recapitulating the length of the canal after initial access,” the guttapercha fit perfectly, and the design of the fi les made it easier for him to perform “root canals that are typically hard to complete.”

In Dr. Steven Dater’s hands, the files “cut easily without pressure and navigated curved canals with ease.” Although he suggested adding a few more file sizes, Dr. Alfred dela Cruz called the fi les “wonderful for mesial canals of lower molars, for MB and DB canals of support molars, and for upper and lower first bicuspids.” Normally using separate variable taper systems for the anterior and posterior, Dr. Jason Wet more said, “This system had files that were satisfactory for all canals encountered.”

“I can confidently navigate tight and curved canals without being afraid of separation or breakage."

Minimally Invasive Design

Minimally invasive by design, the multiple tapers of EXACTTaperH DC fi les ensure fl exibility and help preserve pericervical dentin, according to SS White. Dr. Wetmore, who typically does not use a variable taper system for molar root canals, said these fi les are conservative enough to preserve dentin, with “less aggressive taper, good resistance to separation, and suffi cient fl exibility to clean and shape molar canals.” Suggesting “better color coding of the files,” Dr. Donald Roman liked the “very fl exible fi les with a narrow diameter” that helped prevent stripping and loss of internal root structure in narrow canals in maxillary molars near the furcation. Appreciating “the predictability of such quick instrumentation,” Dr. dela Cruz said the fi les reduce time navigating to the apex, allowing for longer disinfection and more time to dissolve apical pulpal and lateral canal tissue, resulting in increased long-term success.

Compatibility with Current Technique

Available in comparable sizes, lengths, and tapers as other rotary file systems, EXACTTaperH DC files allow clinicians to use a familiar technique and protocol with predictable results, which was appreciated by Dr. Roman and many others. Dr. Nilay Nanavati complimented the “simple and effi cient workflow from instrumentation to obturation,” and Dr. Tony Wu said, “Since the fi les bend and stay curved, it is not as easy to access some canals compared to straight rotary fi les.” Calling it a “simplified system that addresses most root canal cases with ease,” Dr. R.J. Sondkar said the “nonaggressive canal shaping makes it easier and simpler to use than other systems.”

Overall Satisfaction

Calling the EXACTTaperH DC system “efficient, economical, and effective,” Dr. dela Cruz said it “made performing RCTs more predictable and successful.” Dr. Sarubin concluded that the system offers “very good treatment for all types of canals. It makes doing RCTs fun again.”
