Influence of Er:YAG laser ablation on cavity surface and cavity shape

Ablation Rate and Morphology of Superficial and Deep Dentin Irradiated with Different Er:YAG Laser Energy Levels

“…7,12,13 Since Er:YAG laser energy is well absorbed by water, and the higher content of water in dentin facilitates the action of the laser, as does the predominant organic composition of dentin, as this tissue is less resistant to laser ablation than enamel. 12,[17][18][19][20][21] Dentine is a heterogeneous composite material containing 70% by weight of mineral, 20% by weight of organic substances, and 10% by weight of water. 22 The main mineral content of the inorganic component is a nanocrystalline-carbonated apatite, and variants such as fluorapatite, that reinforce a hydrated type I collagen organic matrix and provides the strength and hardness of the dentin.…”

Shear Bond Strength to Enamel of Primary Teeth Irradiated with Varying Er:YAG Laser Energies and SEM Examination of the Surface Morphology: Anin VitroStudy

“…Later research prompted the development of different laser systems, enlarging the scopes and widening their indications in dental practice. By varying some parameters, dental lasers may be used to date for several potential dental applications, including conservative removal of carious lesions, 4-6 removal of nonmetallic ancient restorations, cavity preparation, [7][8][9] and conditioning of pits and fissures prior to the placement of occlusal sealants. 10,11 The effectiveness of the laser relies on its interaction with the irradiated biological tissue, which results from the coefficient of absorption of the laser wavelength by the target tissue.…”

Effect of Erbium-Doped Yttrium Aluminium Garnet Laser Parameters on Ablation Capacity and Morphology of Primary Dentin

“…[1][2][3][4] Regarding the Er:YAG laser settings advised for cavity preparation, pulse energy and pulse repetition rate are the most important parameters, being directly related to the laser's ability to ablate dental substrates. [5][6][7] Several studies 8-10 using permanent teeth have attempted to settle and standardize basic workable parameters to yield optimal and safe ablation of dental hard tissues, but a consensus has not been reached.…”
