Flex-Type files are essential in root canal treatments, offering greater flexibility and control, particularly for curved or narrow canals. Made from nickel-titanium or specially treated stainless steel, these files bend without breaking, adapting smoothly to the canal’s natural shape. Their flexibility reduces the risk of bleeding, transportation, or perforation, ensuring safer and more precise cleaning. They effectively remove debris, infected tissue, and dentin while preserving the canal’s structure. Their smooth, controlled motion prevents excessive pressure, reducing strain on both the tooth and the practitioner’s hand. Used manually or with rotary assistance, they allow for efficient shaping and preparation before obturation. They are available in multiple sizes and tapers, Flex-Type files cater to different anatomical needs, making them a reliable choice for complex endodontic cases.
