What type of laser is referred to as Er:YAG?

Er:YAG stands for Erbium:Yttrium Aluminum Garnet, and this type of laser is specifically designed to be used for hard tissue applications in dentistry. The Er:YAG laser operates at a wavelength of 2940 nm, which is well absorbed by water and hydroxyapatite, making it particularly effective for cutting and ablation of dental hard tissues such as enamel and dentin.

This laser's ability to precisely remove hard tissues with minimal thermal damage has made it a valuable tool in restorative dentistry and oral surgery. It allows for procedures such as cavity preparation, tooth structure removal, and bone contouring. Its effectiveness and reduced risk of thermal injury distinguish it from other types of lasers that may not achieve the same level of precision or safety when used on hard tissues.

In contrast, while dental soft tissue lasers are used for procedures involving gums and other soft tissues, the Er:YAG laser's primary function and optimal performance are centered around hard tissues, confirming it as a dental hard tissue laser.
