DH-W100YG root canal file torque tester is specially used for testing the torsional performance of endo files. Measure the torsional strength, maximum torque, maximum torsion angle, bending strength and handle reliability of root canal files. The torque and torsion angle curves are displayed in real time and support exporting the  A4 paper test reports, which is for medical research. 

You might ask how to inspect a niti file by this machine? Here are a few steps for you.

Inspecting the torsion function of an endodontic NiTi (Nickel-Titanium) file using a torsion testing machine involves subjecting the file to controlled torsional stress to evaluate its mechanical properties, particularly its resistance to twisting or deformation. Here’s a general guide on how this can be done:

1.Setup:

Ensure the torsion testing machine is calibrated and set up according to your guidelines.

Securely mount the endodontic NiTi file onto the testing machine, aligning it properly for accurate testing.

2. Gripping the File:

Use specialized grips to securely hold each end of the endodontic file without damaging its structure.

Ensure that the file is clamped in a way that simulates its clinical use conditions.

3. Applying Torsional Stress:

Gradually apply torsional stress to the file using the torsion testing machine. This stress is applied by twisting one end of the file relative to the other.

Measure and control the applied torque, which represents the force needed to twist the file.

4. Torsional Testing Parameters:

Set the testing parameters, such as the rotational speed and the angle of rotation, according to the testing standards or specific requirements.

Monitor the torsional deformation of the file in real-time.

5. Recording Data:

Use sensors or transducers connected to the testing machine to record important data, such as torque applied, angular deformation, and any signs of failure (e.g., fracture or plastic deformation).

Capture the data throughout the entire testing process.

6. Analyzing Results:

Analyze the recorded data to evaluate the torsional performance of the NiTi file.

Assess the maximum torque the file can withstand before failure or significant deformation occurs.

Examine the torsional behavior, looking for characteristics like elastic deformation and any signs of ductile or brittle failure.

7. Interpretation and Reporting:

Interpret the results in the context of industry standards or specific requirements for endodontic files.

Prepare a detailed report outlining the torsional characteristics of the NiTi file, including any observed failures or deformations.

8. Quality Control:

Use the results to ensure the quality and reliability of the NiTi file. Torsional testing is an essential part of quality control to assess the file’s ability to withstand torsional stress during clinical use.

It’s important to note that torsional testing is just one aspect of evaluating the mechanical properties of endodontic NiTi files. Manufacturers often conduct a battery of tests, including torsional, cyclic fatigue, and other mechanical tests, to ensure the overall performance and safety of their products. Always follow industry standards and guidelines for testing procedures and ensure compliance with relevant regulations.
