background: dental surfaces prepared with different er:yag laser distance may have different characteristics compared with those prepared with conventional instruments. the aim of this study was to investigate the effect of er:yag laser irradiation distance from enamel and dentin surfaces on the shear bond strength of composite with self-etch and etch and rinse bonding systems compared with con...

BACKGROUND This study examined the effect of roughening of the root surface using an erbium-doped yttrium aluminum garnet (Er: YAG) laser on the binding strength of teeth undergoing root canal treatment. MATERIAL AND METHODS Ninety single-rooted teeth were used and assigned randomly to 9 groups (n=10 each). Root canals were prepared using the FlexMaster rotary system. An Er: YAG laser was appli...

OBJECTIVE In this study, we aimed to evaluate and compare the dentinal walls of root-end cavities for the presence of cracks after cavity preparation using US retrotips and Er: YAG laser. MATERIALS AND METHODS Fifty single-rooted teeth were prepared by Protaper NiTi rotary system and obturated by lateral condensation. Three milimeters of root-end was resected. Twenty teeth were prepared with ...

An Er: YAG laser is a near infrared laser with a wavelength of 2.94m. This wavelength is identical to the peak wavelength of the light most readily absorbed by water. When used on living tissue with a sufficient water content, this laser causes a rapid evaporation of the water in just the most superficial layer of tissue, without greatly affecting the tissue in the neighboring area. The present...

BACKGROUND Striae distensae or stretch marks are atrophic linear dermal scars with epidermal atrophy. There are many therapeutic options for management, but no consistently effective modality is available yet. OBJECTIVE We compared the efficacy of 1064 nm long pulse (LP) Nd: YAG laser and 2940 nm variable square pulse (VSP) erbium: YAG laser in the treatment of striae distensae. METHODS Twe...

Lasers represent a real quantum leap forward in the treatment of our patients, including the paediatric patient. The US Food and Drug Administration (FDA) gave approval for the use of the Er: YAG laser in 1997 for both hardand soft-tissue procedures. The erbium doped (erbium particles placed within the YAG crystal) crystal of Yttrium-AluminumGarnet’s (Er:YAG) development and success has made th...

BACKGROUND Treatment of congenital melanocytic nevi (CMN) with intense pulsed light (IPL) has recently produced promising results. OBJECTIVE To evaluate the clinical and histological outcomes of small-to-medium sized CMN treated with IPL alone and in combination with erbium: yttrium-aluminum-garnet (Er: YAG) laser. METHODS We performed a retrospective chart review of 26 small-to-medium size...
