Tough and re- usable Tango-Endo instruments boast a unique, patented flat along the en- tire length. This flat, according to EDS, allows for faster engagement with less resistance, increased flexibility without sacrificing strength and virtually elimi- nates instrument separation. The Tango-Endo system includes its own reciprocating handpiece. The latch-type handpiece is designed to aid in the prevention of binding, and to assist in the preservation of the ca- nals’ unique anatomy. The kit also in- cludes precision matched gutta-percha points, designed for a perfect fit. “Tango-Endo was simple and easy to use, and I did not find it to have much of a learning curve,” says Dr. Joshua Austin, of Texas. “If you are looking for an endo file system that is simple and safe, Tango-Endo is an excellent choice that is also very cost-effective.” “I was blown away by how efficient and easy it was to clean and shape the three canals in about 10 minutes,” says Dr. Scott Graham, of Michigan. “The fit of the Tango gutta-percha points was excellent, too. No tip trimming required. I’m excited about [this] new system.” For more information, visit EDS at booth No. 3319 at the Chicago Midwinter meeting, or go to www.edsdental.com/ tangoendo.

We seek out ways to produce highly ef- fective predictable results. For us, that means no instrument separation as a cause of concern with the full apprecia- tion that our procedures must primar- ily maintain the original integrity of the remaining tooth structure as much as possible.
