,SS White continues to revolutionize root canal treatment with file systems for general dentists and endodontists who seek to conserve valuable tooth structure,
, ,It’s been said that the standards of endodontic access remained in the dark ages for far too long. That began to change over a decade ago when leaders in the field began focusing on pericervical dentin, the area roughly 4 mm coronal to crestal bone and 6 mm apical to crestal bone. This “neck” of the tooth is the most common area for significant root fracture and restorative failure. When pericervical dentin is conserved and left strong, the tooth has a greater chance for long-term survival., , ,It is with this concept in mind that the minimally invasive movement was born. SS White—the company that, in 2002, produced Fissurotomy, the first minimally invasive cavity prep burs—has been at the forefront of this endodontic revolution, developing instruments that allow dentin conservation and stronger teeth that can withstand the forces of occlusion and the effects of disease., ,In 2009, SS White introduced EndoGuide Endodontic Access Burs, followed a few years later by the DCTaper NiTi system, which are the files of choice for endodontists who want to create the most minimally invasive but endodontically successful shapes. Mirroring the natural shape of the root, DCTaper files are uniquely designed to allow deep apical and conservative coronal shaping., ,For general dentists who perform endodontic treatment, SS White has unveiled the next generation of minimally invasive NiTi files, EXACTTaperH DC. The variable decreasing taper preserves more pericervical dentin when compared to others on the market. Smaller tapering in the mid and upper portion results in unmatched file flexibility while providing better initial access and conservative restorative options., ,“EXACTTaperH DC files are a modern, minimally invasive version of [a leading NiTi file] and give the clinician the advantages of dentin preservation without having to change preparation or obturation technique,” said Dr. John Khademi., ,With a 33% smaller maximum flute diameter, EXACTTaperH DC files create an ideal anatomical fit to the natural dimensions of the size and shape of the root canal. The files also provide greater resistance to cyclic fatigue. According to SS White, they are 58% stronger than the closest comparable file, significantly reducing the chance of file separation. SS White’s proprietary heat-treating processes create superior controlled memory and flexibility for up to 90° curves that accommodate even the most complex canal anatomies., ,“Very few files are needed to shape the canals. The flexibility on these files is simply unreal,” said Dr. Reza Farshey., ,The EXACTTaperH DC file system has been designed with multiple tapers that ensure flexibility and cut dentin in specific canal zones. The system’s finishing files produce the proper apical fit for the matching gutta-percha. Available in sizes, lengths, and tapers comparable to popular file systems on the market, EXACTTaperH DC requires no change to current protocols or techniques.
