PY - 2017 TI - Experimental Study on the Effect of Nd:YAG Laser on Dental Hard Tissue: Comparison between Multi-pulse and Free-generation Modes JF - Revista Cubana de FĂ­sica; Vol 34 No 2 (2017) KW - N2 - The goal of the present study is to compare the morphological changes in dental hard tissue that are obtained through the use of passively Q-Switched multi-pulse Nd:YAG laser irradiation, with a free-generation mode Nd:YAG laser. The experimental samples consisted of six healthy third molars that were divided equally and randomly for the two irradiation methods. The depth of each perforation was quantified using optical coherence tomography (OCT). The highest fluency and the shortest duration of the pulses obtained by the multi-pulse laser with a Q-switch allowed for more efficient ablation of the dental material than what was obtained via the free-generation mode.   UR - https://revistacubanadefisica.org/index.php/rcf/article/view?path=
