Komet's H1SML.RASL.006 tungsten carbide instrument, designed for "quick and efficient isthmus preparation during endodontic procedures," is now available in two larger sizes: 008 and 010. Its long, slim neck allows for unimpaired vision of the operative site, according to the company.
H1SML instruments have a sharp, round end, allowing the user to penetrate deeper into the pulp area for easier preparation of an isthmus. In many cases, an isthmus must be created to locate hidden canals between two separate root canals that might contain pulp tissue or, in some cases, infected and necrotic tissue.
The H1SML instrument, identified with a green ring, is durable and easy to sterilize, Komet noted. For optimal results, Komet USA recommends the instrument be used without cooling. There's no need to apply additional pressure, the company said; chips are removed with the air generated from using a multifunctional handpiece.
