background dentin sensitivity is one of the most important problems in dentistry. enamel loss due to root exposure is serious issue and common exposure is one of the reasons for dentin hypersensitivity. there are different methods for solving this problem. one of the most conservative and least expensive methods is use of casein phosphopeptide-amorphous calcium phosphate (cpp-acp) paste. object...

We investigated room-temperature pulsed lasing in heavily doped Fe:ZnSe single crystals. The active elements were pumped by a Q-switched Cr 3+ :Yb :Ho :YSGG laser operating at 2.87 μm. Our results show that the generation of short pulses has deep high-frequency modulation associated with relaxat...

Introduction: Corticotomy-facilitated orthodontics provides a means for rapidly moving teeth purportedly with little damaging effects to the periodontium and with greatly reduced treatment time. The aim of this study was to enhance the orthodontic tooth movement by reducing the cortical bone layer (resistant to bone re-sorption relative to spongious bone) following Erbium, Chromium doped Yttriu...

Microleakage following root-end resections has a direct influence on the outcome of surgical endodontic procedures. This study compared the microleakage after root-end resections performed by the Er, Cr: YSGG laser or carbide burs with or without the placement of MTA, and evaluated the presence of microcracks and gaps at the interface of GP/MTA and the canal walls. Ninety single-rooted teeth we...

BACKGROUND Several laser technologies exist for improving rhytides, pigmentation, and skin texture. Recent advances in technology introduced a new wavelength, 2,790 nm, erbium:yttrium-scandium-galium-garnet (Er:YSGG) for treatment of photoaging. 2,790 nm Er:YSGG has a water absorption coefficient between CO(2) laser and Er:YAG laser and has both ablative and fractional-ablative capabilities. ...
