Woodpecker / DTE Apex Locator - DPEX V

1. What are the main features of the DPEX V Apex Locator?

• It has a bright LCD display with clear images, using different colors to indicate the file’s trajectory.
• Advanced impedance measurement technology ensures accurate readings.
• Components like the File Clip, Lip Hook, and Touch Probe are autoclavable to prevent cross-infection.
• It has a rechargeable battery, eliminating the need for frequent replacements.

2. How do I prepare the DPEX V Apex Locator for measurement?

• Insert the measuring wire into the socket on the right side of the unit.
• Connect the File Clip and Lip Hook to the measuring wire. If using with an Endo Motor, attach the white end to the lip hook.
• Test the wire connection before each use by ensuring the lip hook touches the file clip. The connection icon should be steady on the screen.

3. How do I test the DPEX V Apex Locator with a tester?

• Turn off the device and remove the measuring wire.
• Insert the tester and power on the device. The display should show within ±3 bars of the 0.5 mark. If it does not, contact the manufacturer.

4. How do I determine the working length using the DPEX V Apex Locator?

• When the indicating bar reaches 0.0 and “APEX” is displayed, the file has reached the apical foramen.
• Subtract 0.5-1.0 mm from the measured length to get the working length.
• Ensure you take an X-ray to confirm the results.

5. Can the DPEX V be connected to an Endo Motor?

• Yes, it can be connected via a USB line to compatible Endo Motors.
• The Contra-angle icon should light up to indicate proper communication between the Apex Locator and the Endo Motor.

6. How do I charge the DPEX V?

• Connect the AC adapter to the charging port on the left side of the device.
• A yellow indicator means charging is in progress. When it turns green, charging is complete. Charging usually takes around 120 minutes.
• Do not use the device while it’s charging.

7. What should I do if the length measurement is inaccurate?

• Ensure the measuring wire and file clip are properly connected.
• Make sure there’s no blood, saliva, or debris on the tooth surface or crown.
• Check for broken wires or worn file clips and replace them if necessary.

8. Are there any conditions that may affect the measurement accuracy?

• Yes, conditions like tooth cracks, metal crowns, or bleeding can cause inaccurate measurements.
• Using a too-small file or measuring in extremely dry or wet conditions may also lead to errors.

Cleaning, Disinfection, and Sterilization FAQs:

1. What type of cleaning agents should I avoid to prevent damaging the device?
Avoid using strong detergents and disinfectants with a pH greater than 9 (alkaline) or less than 5 (acidic), as they can reduce the product's lifespan. The manufacturer will not be responsible for damage caused by such chemicals.

2. How many times can I sterilize the lip hook, file clip, and touch probe?

• File clip: up to 200 times
• Lip hook and touch probe: up to 1000 times

3. What are the steps for cleaning after use?

• Remove the measuring wire and rinse the product with pure, distilled, or deionized water.
• Dry the product with a clean, soft cloth and place it in a clean tray. Cleaning must be done no later than 24 hours after the operation.

4. Can I use ultrasonic cleaning?
No, ultrasonic cleaning is not recommended for these products.

5. How do I perform automated cleaning?
Use a washer-disinfector certified according to EN ISO 15883, ensuring it has a flushing connector for internal cavities. Cleaning agents such as pure water, distilled water, deionized water, or multi-enzyme solutions can be used.

6. What is the recommended disinfection procedure?
Automated disinfection is preferred, using a washer-disinfector certified according to EN ISO 15883. The disinfection temperature should not exceed 134°C, and the process should last no more than 20 minutes.

7. How should the device be dried after cleaning?
You can use either compressed air (max 3 bar pressure) or a medical drying cabinet at 80°C to 120°C for 15–40 minutes. Ensure drying is done in a clean environment.

8. What should I do if there are still visible stains after cleaning?
If stains remain, repeat the entire cleaning and disinfection process. Do not proceed with sterilization until the product is visibly clean.

9. What are the recommended sterilization procedures?
Only use steam sterilization via the fractional pre-vacuum procedure. The highest sterilization temperature should be 138°C, with at least 4 minutes at 132°C to 134°C and a pressure of 2.0 to 2.3 bars.

10. Can I store the sterilized device indefinitely?
No, after sterilization, the product should be stored in a medical sterilization bag in a special storage cabinet. The storage time should not exceed 7 days. If exceeded, reprocess before use.

11. What precautions should I take during transportation?
Prevent excessive shock and vibration, avoid exposure to the sun, and ensure it is not mixed with dangerous goods during transportation.
