General Usage and Features
Q: How is the D-Laser Blue different from regular lasers?
A: Compared to typical dental lasers, the D-Laser Blue offers:
- Blue wavelength (450 nm), which provides greater efficiency for soft tissue cutting.
- Capacitive touch screen for easier operation.
- Built-in large-capacity lithium battery for portability and extended use without needing constant recharging.
- Preloaded treatment programs (20+) to simplify setup and reduce user error.
- Sterilizable parts: Autoclavable fiber tips and handpiece sleeves to prevent cross-infection.
- Automatic shutdown feature after 5 minutes of inactivity for safety.
Q: Can the D-Laser Blue be used for different oral surgeries?
A: Yes, it is effective for various procedures such as abscess treatment, frenectomy, pulp disease therapy, and general soft tissue surgeries.
Safety and Contraindications
Q: Are there any patients who shouldn’t use this laser?
A: Yes, the laser should not be used on:
- Patients with hemophilia or pacemakers
- Patients with heart disease, young children, or pregnant women without special precautions
Q: What safety measures are required during use?
A: All personnel (including the doctor, assistants, and patient) must wear laser goggles provided by the manufacturer to protect their eyes. Unauthorized goggles should not be used.
Q: What should be done if the aiming beam is not visible?
A: Check the beam setting and increase it if necessary. If the problem persists, replace the fiber optic tip or contact the dealer.
Handling and Maintenance
Q: How should the fiber tips be prepared before surgery?
A: Before use, the fiber tip must be cut and activated. Gently traverse the fiber with the cutting pen to remove any debris or damaged parts. Activate the tip by running it over articulating paper with the laser set at 976 nm and 3W continuous power.
Q: How should the laser be cleaned and maintained?
A: Ensure the device is clean before and after each use. Handle the handpiece with care to avoid scratches, and avoid pulling or bending the tail wire to prevent damage.
Q: What precautions should be followed for safe storage?
A: Store the D-Laser Blue away from heat sources, magnetic fields, precision instruments, and unstable voltage environments. Avoid using it near flammable anesthetic mixtures.
Charging and Battery Information
Q: How does the D-Laser Blue indicate its battery status?
A:
- Power-off state: The screen displays a charging icon until fully charged.
- Power-on state: A yellow icon appears during charging, turning green when fully charged.
Q: Can the device operate while being charged?A: Yes, the D-Laser Blue can be used while connected to the original power adapter. However, it is primarily designed to function as a battery-powered, portable unit.
Procedural FAQs
Q: How is a frenectomy performed using the D-Laser Blue?
A:
- Apply tension to the frenum with a retractor or hemostat.
- Make a perpendicular incision at the attachment point and extend toward the periosteum without damaging it.
- For lingual frenectomy, be cautious of vascular beds under the tongue.
- Use saline rinses post-procedure, and sutures are generally not required.
Q: How does the D-Laser Blue treat abscesses?
A:
- Create a drainage path by making an incision at the coronal spot of the lesion.
- Probe inside the lesion without activating the laser to explore the area.
- Activate the laser while withdrawing the fiber to help clear exudate and pathogens.
- Repeat until the drainage path is clear and administer oral antibiotics as needed.
Troubleshooting
Q: What should I do if the laser beam is not working properly?
A: Try increasing the power. If the laser beam still doesn't work at 3W or higher, replace the fiber optic tip. If the issue persists, contact the dealer for assistance.
Q: What if the foot switch doesn’t control the laser?
A: Ensure the foot switch is fully charged and properly paired with the device. If the problem continues, seek technical support from the dealer.
