Clinical Assessment of Er,Cr:YSGG Laser Application for Cavity Preparation

Journal of Clinical Laser Medicine & Surgery, 2002
In this study, an erbium,chromium:YSGG (Er,Cr:YSGG) laser emitting at a wavelength of 2.78 microm was clinically applied to remove caries and prepare cavities, and the clinical outcome was evaluated. Effective clinical application of Er,Cr:YSGG laser had been expected from previous studies. This study included 44 patients (26 females, 18 males; aged 23-

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

Bonding strength of universal adhesives to Er,Cr:YSGG Laser-Irradiated Dentin

Nigerian Journal of Clinical Practice, 2018
Universal adhesives have been recently introduced for use as self-etch or etch-and-rinse adhesives depending on the dental substrate and clinical condition. However, their bonding effectiveness to laser-irradiated dentin is still not well known. Therefore, the aim of this study was to compare the shear bond strength (SBS) of two universal adhesives ...

Lip Repositioning Surgery Using an Er,Cr:YSGG Laser: A Case Series

The International Journal of Periodontics & Restorative Dentistry, 2020
Excessive gingival display (EGD) is a common esthetic concern. Lip repositioning surgery (LRS) was introduced as one of the treatment options to manage EGD. LRS can be used for skeletally and/or muscularly induced EGD. The present case series applied LRS using an Er,Cr:YSGG laser to treat 24 patients with minor vertical maxillary overgrowth or a ...

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.

Ablation of Selected Dental Materials Using Er,Cr:YSGG Laser

Materials Science Forum, 2017
The effect of Er,Cr:YSGG laser for ablation of commercialized adhesive dental materials were studied using 12 sets of tooth samples. The surface morphology and composition of the tooth samples was observed before and after irradiation using FESEM and EDX. Time dependency of exposure is observed in the tooth sample.

Assessment of root caries removal by Er,Cr:YSGG laser

SPIE Proceedings, 2007
The present study aimed to compare root caries removal by air turbine and Er,Cr:YSGG laser, and examine morphological changes after these caries removal techniques under scanning electron microscopy (SEM). Seventy two extracted human carious-free third molars were used in this study. After the in vitro root caries induction using S.
