Abstract
Laser technology has been extensively used for dental treatment since the 1990s [1]. In particular hard tissue ablation is performed by Er:YAG lasers due to their affinity with water and hydroxipatite, thus avoiding the formation of micro- and macro-cracks, and thermal damaged areas[2 – 5]. On the other hand Er:YAG lasers are affected by cumbersome instrumentation, and operation durations can be higher than the ones of traditional instruments. Records of dental surface treatment with ultra-short pulsed lasers, 150 – 500 fs, are also present, at such pulse duration remarkable results have been obtained, regardless to the laser emission wavelength [6,7].
