OHC Progressive Taper Gold Rotary Hand Files 25mm F2 (Pack of 6)

• Create straight-line access to the canal orifice.
• In the presence of a viscous chelator (such as Glyde® File Prep root canal conditioner) passively scout the coronal 2/3 with 10 and 15 hand files. Gently work these instruments until a smooth, reproducible glide path is confirmed. Alternatively, mechanized glide path files (such as ProGlider® or PathFiles®) may be used after a 10-hand file.
• In the presence of NaOCl, “float” the S1 in the canal and passively “follow” the glide path. Before light resistance is encountered, laterally “brush” and cut dentin on the outstroke to improve straight-line access and apical progression. Always brush away from the furcation.
• Continue shaping with S1 as described until the depth of the 15-hand file is reached.
• Use the S2, exactly as described for the S1, until the depth of the 15-hand file is reached.
• In the presence of a viscous chelator or NaOCl, scout the apical 1/3 with 10 and 15 hand files and gently work them until they are loose at length.
• Establish working length, confirm patency, and verify the presence of a smooth reproducible glide path in the apical 1/3.
• Use the S1, with a brushing action, until the working length is reached.
• Use the S2, with a brushing action, until the working length is reached.
• Reconfirm working length, irrigate, recapitulate, and re-irrigate, especially in more curved canals.
• Use Finishing File F1, in a “non-brushing” action, with each insertion deeper than the previous insertion until working length is reached. Do not leave the file at working length for longer than one second.
• Gauge the foramen with a 20-hand file. If the instrument is snug at length, the canal is shaped and ready to be obturated.
• If the 20-hand file is loose at length, proceed to the F2 and, when necessary the F3, F4, and F5, with the same non-brushing motion to working length, gauging after each Finishing file with 25, 30, 40 or 50 hand files respectively.
• If necessary, use the SX with a brushing motion to move the coronal aspect of the canal away from furcal concavities and/or to create more coronal shape. SX can also be used to shape canals in shorter roots optimally.
• The PREMIUM TAPER GOLD sequence is the same regardless of the length, diameter, or curvature of the canal.
