Features: - Shaping files pre-enlarge canals using the familiar outstroke brushing technique. - Flexibility: +24% increased flexibility1 compared to ProTaper Universal. - Durability: x2.6 greater resistance to cyclic fatigue. - Accessibility: Shorter 11 mm handle allows improved accessibility to teeth. - Design: The non-cutting tip design allows each instrument to safely follow the secured portion of the canal while the small flat area on the tip enhances its ability to find its way through soft tissue and debris. - Efficiency: The convex triangular cross-section and progressive taper enhance cutting action while decreasing rotational friction between the blade of the file and dentin. Specifications: - Size: S1. - Length: 25 mm. - Material: NiTi.
