Permeability of the 405-nm diode laser light into the dentin

抄録

In this study, we measured the permeability of the 405-nm diode laser light into the dentin for clinical use such as dental hypersensitivity or pulp capping. Forty extracted bovine mandibular anterior teeth were used. Dentin permeability was about 30% at thickness of 0.5mm and 15% at thickness of 1mm and 5% at thickness of 2.0mm.There was a correlation between the permeability and the thickness of the dentin. This result suggested that the 405-nm diode laser may become one of the options of the treatment of dental hypersensitivity or the inflamed pulp.
