A clinical evaluation of a high-pulse rate erbium: YAG laser for dental cavity preparation

摘要

A wave length of EnYAG laser is 2940 nm; it has high absorbability in water, and is notable as dental hard tissue cutter. Previous study at 10-Hz irradiation showed good result in vivo. The aim of this study is to evaluate the effect of the higher pulse rate, 30 Hz, EnYAG laser for adhesive resin cavity preparation in vivo. Sixty cavities were prepared by high-pulse EnYAG laser, and clinical symptoms were recorded by operator and donor, respectively. The results showed that high-pulse rate Er:YAG offers less painful, safe and effective cavity preparation without any side effect.
