ROEKO and HYGENIC paper points are sterile and highly absorbent, and being non-adhesive, allow for reliable and easy drying of the root canal. Fast and safe obturation can be conducted with GuttaFlow bioseal, a bioactive three-in-one obturation material that combines cold free-flow gutta-percha with a sealer and bioceramic in one outstanding filling system and with HYGENIC and ROEKO Guttapercha points. Recent studies have evaluated the in vitro toxic- ity of endodontic sealers such as GuttaFlow bio- seal and GuttaFlow 2, as well as Angelus’s MTA-FILLAPEX and Dentsply Sirona’s AH Plus, on stem cells from the periodontal ligament. It was found that especially GuttaFlow bioseal and also GuttaFlow 2 showed lower toxicity levels and higher cell viabilities than the competing sealers did. In addition, GuttaFlow 2 demonstrated a better result in terms of microleakage and seal- ing ability than the competing sealers did. COLTENE’s HyFlex instrument, probably its best-known product, has set a new benchmark for NiTi rotary files. HyFlex EDM, the latest gen- eration, integrates the controlled memory ef- fect of its predecessor, HyFlex CM. Furthermore, owing to an innovative manufacturing process using electrical discharge machining, HyFlex EDM has a specially hardened surface that makes the files stronger and more fracture-re- sistant. The controlled memory of both HyFlex CM and HyFlex EDM gives the instruments a number of important properties, including ex- treme flexibility, superior canal tracking, regen- eration after repeat autoclaving and strong fa- tigue resistance. To achieve these characteristics, HyFlex CM and HyFlex EDM are manufactured using a special thermomechanical process whereby the crystal- lographic phase transition from austenite to martensite at room temperature results in an ad- vanced controlled memory of the material, mak- ing both files extremely flexible. “We successfully managed to give our NiTi material shape memory properties,” said Müller. “We did this by changing the DNA of the material through a switch from low to room temperature. Our idea became not only an innovation, but a product many of our competitors have tried unsuccessfully to copy.” Introduced at the International Dental Show in Germany two years ago, the new HyFlex EDM re- duces the number of files needed to two to three, particularly in straight and larger canals.
