DClase Soft Tissue Diode Laser

Major Benefits of DCLase:
1. Easy portable device to install and ready to use (plug and play)
2. Procedures are now easier and cleaner (great hemostasis)
3. Safer than other cutting devices (e.g. electrosurge)
4. Reduced healing time and minimal charring of the tissue
5. More than enough power to deal with the most fibrous tissues

DCLase is the most advanced dental diode laser on the market. It is specially designed to perform the soft tissue procedures in a least invasive and less traumatic manner. DCLase helps reduce healing time while providing simultaneous hemostasis; all while achieving minimal charring of the tissue.

With a higher absorption in hemoglobin, oxyhemoglobin and water; studies prove the laser’s ablating efficiency is significantly enhanced. The 980nm wavelength takes advantage of the 70% water content of the tissue which allows the high absorption of its radiant light energy into the tissue.

Why 980nm wavelength?

- 10 times higher absorption in water than 810nm wavelength
- Water can be used for cooling
- Minimal area of necrosis and charred tissue
- Precise tissue ablation
- Use of radiant energy instead of conductive energy (heat)
-Excellent hemostasis with high absorption in hemoglobin and oxy-hemoglobin
-Reduced patient post-operative pain and tissue swelling

Why 7 watts & Super Pulses?

- Fast tissue ablation with the high fluency technique
- Cut through fibrous tissues e.g. frenectomy
- Super Pulses allows tissue to cool down while using high power
- Optimal tissue vaporization
- Laser bleaching/ tooth whitening
- Enhanced patient comfort

The wavelength of a diode laser determines its properties and capabilities; in addition, the wavelengths and absorption levels affect the tissue differently. The right balance between the level of absorption by water, hemoglobin and type of wavelength is important to achieve optimal laser-tissue interaction. 980nm wavelength has the best balance.

The absorption depends on:
- Water (tissue contains around 70% of water): the better the water is absorbed the better the laser cuts. Absorption of light energy in water: 3% for 810nm, 15% for 1064nm, 35% for 980nm*
- Hemoglobin: high absorption by Hemoglobin produces char free coagulation and successful hemostasis
- Wavelengths: 980nm cuts more optically than thermally. The 980nm laser energy is absorbed vs the thermal effect (carbonized tip / heat)) used by other wavelengths

Why is the right balance between the level of absorption by water, hemoglobin and type of wavelength is important?

For example, the 810nm wavelength cuts thermally at it is less absorbed by water and hemoglobin than the 980nm wavelength. 810nm is well absorbed by pigmented structures providing for good hemostasis and effective cutting of tissue however, the fiber tip requires to be initiated (carbonized tip) in order to ablate. The ‘initiation’ traps the heat at the fiber tip and cut tissue via conductive heat (‘hot tip’). The heat generated cuts, vaporizes the tissue on the other hand the heat can also produce collateral tissue damage, swelling, tissue necrosis, charring and patient discomfort (810nm may require more local or topical anesthetic).

The 980nm wavelength cuts and coagulates optically; it doesn’t require an initiated tip (‘hot tip’) because the laser energy is well absorbed by water and hemoglobin. 980nm uses radiant energy to enhance vaporization of the tissue instead of heat. 980nm also maintains a controlled depth penetration and essentially eliminates collateral tissue damage. 980nm minimizes post operative swelling and patient discomfort as well as charring free.
