Paper Abstract
By using the developed by us approaches and instrumentation, we have obtained and presented series of systematized
data, which are important for the use of the laser light in infrared (IR) spectral region. The obtained data include: 1) reflectivity of the human tooth dentin; 2) the spatial intensity distribution in the cross-section of the light beam penetrating the tooth’s dentin; 3) the absorbed and the diffused parts of the laser light that have been determined separately through combination of optical and calorimetric techniques. The last result is the most important because it permits to calculate the dentin absorption and scattering coefficients. The study is performed for the laser light at two
easily generated wavelengths – 1.06 μm and 1.36 μm, emitted by the Nd:YAG laser that is well known, commercially
available, economical and widely used in many laboratories and medical institutions. The study is made on the basis of
fresh in-vitro teeth samples from the persons of Bulgaria, Sofia region.
