Paper Abstract

In recent years the dental use of the Er:YAG has found increasing interest. Most of the papers published so far concentrate on in vitro studies on cavity preparation, including the determination of ablation rates, measurements of temperature increase, microscopical analysis, and studies on the effect of water spray. The results are qualitatively in agreement and reveal a combination of high ablation efficiency and small side effects superior to other laser systems. Quantitative results, however, e.g., on ablation threshold or crater depths, sometimes differ. Some of these differences now can be explained and related to laser parameters or experimental conditions. Besides increasing the understanding on laser tissue interaction, the actual research enlarges the potential applications of the Er:YAG laser, such as for condition of enamel or dentin surfaces to enhance the bonding of composites. With the use of fibers, additional perspectives are given in periodontics and endodontics, e.g., for concrement removal or root canal preparation or sterilization.
