This paper describes a comparative study of residual heat deposition of Er:YAG and Er,Cr:YSGG lasers during ablation of hard dental tissues. Residual heat deposition was obtained from measured irradiated hard tissue temperature decay characteristics immediately following Erbium laser pulses. The measured residual heat was larger in enamel than in dentine for both Er:YAG and Er,Cr:YSGG […]
Dental Laser Drilling: State of the Art with the Latest Generation of variable Square Pulse Erbium Dental laser Systems
The most recent technological breakthroughts incorporated in the latest generation of Variable Square Pulse (VSP) Er:YAGdental lasers involve two additional features: SSP (Super Short Pulse) mode for extremely fine and minimal invasive laser ablation; and MAX mode for maximum optical drilling speeds. The objective of this study was to make a comparision between the two […]
Laser Profilometry for the Characterization of Craters Produced in Hard Dental Tissues by Er:YAG and Er,Cr:YSGG Lasers
A new, highly accurate and repeatable methodology based on the principle of optical triangulation to measure ablation rates in hard dental tissues is introduced. Using this methodology, a comparison is made between the two leading laser wavelengths for hard tissue procedures in dentistry, Er:YAG (Fidelis Plus III, Fotona) and Er,Cr:YSGG (Waterlase MD, Biolase). In-vitro measurements […]
