Rotoflex Gold files are mechanized NiTi endodontic instruments used to prepare root canals.

• Made of high quality NiTi alloy with flexible performance after special heat treatment process.
• Improved the fracture resistance.
• Forward cutting angle with excellent cutting efficiency, easy to discharge debris.
• The round tip can prevent steps or piercing through by the side.
• Adaptive thread makes the files efficient ,flexible and high strength.

Rotoflex Gold Operation process:

🔹Step 1:

• Probe the root canal with a #10 K-file to ensure a glide path exists.

• Use a #16 PA-FILE, advancing slowly with a gentle pecking motion, avoiding excessive pressure.

• Stop and withdraw the file upon feeling resistance.

• Then, use a #10/02 hand K-file to remove debris.

• Flush and lubricate the canal thoroughly.

🔹 Step 2:

• Enlarge the coronal portion of the root canal with the R# file, advancing slowly with a pecking motion.

• Exit upon resistance.

• Use a #15/02 hand file to check if the canal is patent.

• Flush and lubricate.

• After using the open file, the root canal orifice should be noticeably wider.

🔹 Step 3:

• Insert a #20/04 root canal file and prepare the apical area to the working length with a gentle pecking motion.

• Withdraw upon resistance.

• Use a #15/02 hand file to confirm canal patency.

• Flush and lubricate.

🔹 Step 4:

• Insert a #25/04 root canal file and prepare the apical area to the working length, moving forward gently.

• Withdraw upon resistance.

• Check patency with a #15/02 hand file.

• Flush and lubricate.

• Optional: If a larger canal reaches working length here, skip directly to Step 6.

🔹 Step 5:

• Insert a #30/04 root canal file to enlarge the apical portion to the working length.

• Proceed slowly with a pecking motion, exiting upon resistance.

• Confirm patency with a #15/02 hand file.

• Flush and lubricate.

🔹 Step 6:

• Insert a #25/04 root canal file to shape the middle third of the root canal, advancing to the working length.

• Use a gentle pecking motion, exit upon resistance.

• Confirm patency with a #15/02 hand file.

• Flush and lubricate thoroughly.
