Lasers in dentistry: clinical application today and tomorrow

Various laser systems are discussed for use in dentistry today. The applicability of the Nd:YAG and the CO2 laser is mainly limited by thermal side effects. No clinical indications are given for the UV-excimer lasers because of the low efficiency and the possible mutagenicity. The Er:YAG laser has an exceptional role. Because of his special thermomechanical process the Er:YAG laser can be used in many indications in dentistry today or in the future.
