The effects of laser light on the biological structures are dependent on the laser energy absorbed by different tissue chromophores. The target chromophores of the CO2 lasers are hydroxyapatite and water. Amongst all CO2 lasers, the Dentaray™ 9.6µm wavelength has the highest absorption in hydroxyapatite which is presented in hard tissues such as enamel, dentin and bone.
The optimal combination of 9.6µm wavelength, high repetition rate, super short pulses and water-cooling results in a fast, precise and minimally invasive hard tissue ablation without carbonization. The treated surfaces appear clean, free of smear layer, retentive and appropriate for adhesive restorations.
For soft tissue treatments Dentaray™ 9.6µm CO2 Laser is designed to cover all the advantages of the conventional CO2 lasers. The soft tissue procedures can be performed quickly, minimal-invasively, with less bleeding, resulting in minimum trauma to the treated tissue and less post-operative complications.
In preventive dentistry, preliminary studies suggest that the 9.6µm wavelength markedly inhibits caries progression in pits and fissures in comparison to fluoride varnish1 and successfully inhibits demineralization of tooth enamel2, turning the Dentaray™ to be the perfect dental seal.
For better control and safety during the treatment, the special Dentaray™ scanner automatically irradiates the target area in a constant motion mode to prevent overheating and damage of the dentin-pulp complex.
