Effect of Er,Cr:YSGG laser on human dentin fluid flow

Lasers in Medical Science, 2012
The aim of the current investigation was to assess the rate and magnitude of dentin fluid flow of dentinal surfaces irradiated with Er,Cr:YSGG laser. Twenty extracted third molars were sectioned, mounted, and irradiated with Er,Cr:YSGG laser at 3.5 and 4.5 W power settings.

Reconditioning of ceramic orthodontic brackets with an Er,Cr:YSGG laser

Lasers in Medical Science, 2012
It is now known that erbium lasers are effective in composite removal, but there is minimal information about their efficacy on recycling of ceramic brackets. This study, therefore, aimed to determine the percentage of remaining adhesive on the base and the shear bond strength of debonded ceramic brackets after being reconditioned by an Er,Cr:YSGG ...

Histopathological evaluation of pulpotomy with Er,Cr:YSGG laser vs formocresol

Lasers in Medical Science, 2007
The purpose of this study was to histologically investigate whether pulpotomy with Er,Cr:YSGG laser is an acceptable alternative for formocresol. Pulpotomy of 48 dog's primary canine teeth was performed with formocresol or Er,Cr:YSGG laser. Histological evaluations on hematoxylin and eosin-stained pulp tissues were made by an optical microscope 7 or 60

2.8 μm Er,Cr:YSGG laser beam hollow waveguide transmission

LEOS '95. IEEE Lasers and Electro-Optics Society 1995 Annual Meeting. 8th Annual Meeting. Conference Proceedings, 2002
Er,Cr:YScGG is an important laser material for medical applications in the mid-infrared because of the strong absorption of its 2794 nm line in water. This wavelength has been demonstrated to have reasonably high transmission in hollow glass waveguides, making a practical and convenient delivery system for the beam.
