Abstract

In the last decade, lasers found a number of indications in dentistry. However, there is still one problem: the narrow spectrum of usefulness for individual radiation wavelengths. The aim of our study is to demonstrate the use of a compact three-frequency pulsed Nd-YAG laser for more than one treatment, namely disinfection, coagulation, selective ablation, and soft tissue removal. The laser wavelengths and the maximal energies achieved were the following: 1.06 um, 1.32 um, 1.44 um and 830 mJ, 425 mJ, and 200 mJ, respectively. It has been found that all of the investigated wavelengths exhibit disinfection properties. Moreover, radiation of 1.06 um wavelength removes soft tissue and exhibits also coagulation properties. Radiation of 1.44 um is most useful for selective ablation of initial caries and disinfection, and 1.32 um radiation can be used for precise ablation when higher energy is applied.
