بررسی برهمکنش لیزر Er,Cr:YSGG با بافت سخت دندان
Background and Aims: Nowadays lasers are used as alternatives to the tooth preparation because of reducing pain, bloodshed and stress. The aim of this study was to observe the effect of Er,Cr:YSGG laser on the dental hard tissues. Materials and Methods: For this studty, molar teeth with no caries or dental restoration and enamel cracks were used. The laser power were taken from 0.5, 1, 1.5, ...

متن کاملUnderstanding the response of dental enamel to mid-infrared radiation
Human dental enamel has a porous mesostructure at the nanometre to micrometer scales that affects its thermal and mechanical properties relevant to laser treatment. We exploit finite element models to investigate the response of this mesostructured enamel to mid infrared lasers (CO2 at 10.6 μm and Er:YAG at 2.94 μm). Our models might easily be adapted to investigate ablation of other brittle co...
متن کاملThe role of mesoscopic modelling in understanding the response of dental enamel to mid-infrared radiation.
Human dental enamel has a porous mesostructure at the nanometre to micrometre scales that affects its thermal and mechanical properties relevant to laser treatment. We exploit finite-element models to investigate the response of this mesostructured enamel to mid-infrared lasers (CO(2) at 10.6 microm and Er:YAG at 2.94 microm). Our models might easily be adapted to investigate ablation of other ...
متن کاملFemtosecond laser for cavity preparation in enamel and dentin: ablation efficiency related factors
To study the effects of laser fluence (laser energy density), scanning line spacing and ablation depth on the efficiency of a femtosecond laser for three-dimensional ablation of enamel and dentin. A diode-pumped, thin-disk femtosecond laser (wavelength 1025 nm, pulse width 400 fs) was used for the ablation of enamel and dentin. The laser spot was guided in a series of overlapping parallel lines...
