  • Title: [Ablative effect of an Er:YAG laser on enamel and dentin].
    Author: Keller U, Hibst R.
    Journal: Dtsch Zahnarztl Z; 1989 Aug; 44(8):600-2. PubMed ID: 2639063.
    Abstract:
    The effectiveness of a pulsed infrared Er:YAG laser beam at a wavelength of 2.94 micron in removing hard tooth structure was studied. The defects produced by the laser beam were evaluated quantitatively and morphologically as a function of energy and pulse frequency. The use of this instrument allows the efficient removal of enamel and dentin while sparing the surrounding tissues.
