OGSF sequence provides for optimal preparation

The set of four HyFlex EDM files supports dentists in providing safe, reliable and efficient root canal preparation following an easily remembered file sequence which takes the four essential stages of treatment into account. COLTENE recommends this precisely coordinated file sequence suitable for all cases: Opener— Glider— Shaper—Finisher. The HyFlex EDM files can be ordered in a set of four in this OGSF sequence. “In endodontics, the preference for reciprocating or rotary preparation is primarily a matter of taste. However, experts do agree that the introduction of standard procedures and checklists increases the safety and reproducibility of results,” said Dr Barbara Müller, senior head of endodontics at COLTENE. For example, practice procedures can be easily optimised if the chairside assistant does not have to be constantly retrained as to the appropriate instruments on the tray, but knows what sequence is being used.

The orifice opener is like the soup spoon: it starts the sequence by creating the access cavity. The main task of the knife and fork is performed by the glide path file and the shaping file. While the glide path file helps to create the appropriate glide path following the natural course of the canal, the shaping file then quickly and efficiently removes bacteria as well as infected tissue and gives the canal the necessary shape for good obturation. The finishing file serves as the dessert spoon for a successful finish: it ensures that the apical area is sufficiently cleaned and that there is adequate space for irrigating solutions to penetrate to the apex. The use of well-coordinated files makes it particularly convenient to change from one file to the next.
