“…Moreover, Er,Cr:YSGG laser also coincides with the narrow absorption band of OH -in the hydroxyapatite mineral. It is proved that they are the most suitable candidates for cavity preparation and caries removal [4,5] . The primary mechanism reported for IR lasers is the thermo-mechanical: light absorption by water and / or mineral components in thin tissue layer could heat interstitial water and lead to internal pressure reaching the ultimate tensile strength of the tissue, consequently resulting in explosive removal of the outer layers of dental hard tissue.…”

To examine the temperature changes in the pulp chamber during cavity preparation in dentin with the Er:YAG laser (2940 nm), a total 20 intact premolars teeth were divided into 4 groups for dentin ablation with different radiant exposures at 4Hz and 8Hz with and without water spray. A K-type thermocouple was used to monitor the temperature changes in pulp chamber during laser treatment. The total time of irradiation was 70 sec. the water spray rate was 3 mL/min. It showed that maximum temperature rise increases with the increasing of radiant exposure and pulse repetition rate and the additional water cooling during laser ablation can significantly reduce the temperature rise in pulp chamber which will benefit to avoid or reduce thermal damage to tooth structure and dental pulp. The highest rise of temperature in the pulp was achieved with 20 J/cm 2 and 8 Hz (19.83 °C ). For all sample without water spray, the rise of temperature was exceed 5 °C . In contrast, with water spray, the temperature rise in the pulp can be firmly controlled under 1°C. The results also indicated that ablation rate and efficiency can be enhanced by increasing the incident radiant exposure and pulse repetition rate, which simultaneously producing more heat accumulation in dental tissue and causing thermal damage to dental tissue. By applying an additional water spray, thermal damage can be significantly reduced in clinical application.

“…However, erbium lasers are currently still mainly applied for the preparation of dental hard tissues like enamel, dentin, and cementum 11–15. A sole and exclusive use of Er:YAG lasers for the treatment of bony tissue as a matter of routine is merely in fledgling stages and clinical trails demonstrating significant surgical benefits and long-term success are scarce.…”

The erbium-doped yttrium aluminium garnet (Er:YAG) laser has emerged as a possible alternative to conventional methods of bone ablation because of its wavelength of 2.94 μm, which coincides with the absorption peak of water. Over the last decades in several experimental and clinical studies, the widespread initial assumption that light amplification for stimulated emission of radiation (laser) osteotomy inevitably provokes profound tissue damage and delayed wound healing has been refuted. In addition, the supposed disadvantage of prolonged osteotomy times could be overcome by modern short-pulsed Er:YAG laser systems. Currently, the limiting factors for a routine application of lasers for bone ablation are mainly technical drawbacks such as missing depth control and a difficult and safe guidance of the laser beam. This article gives a short overview of the development process and current possibilities of noncontact Er:YAG laser osteotomy in oral and implant surgery.
