BACKGROUND Long-pulsed Nd : YAG laser has been used in treating larger and deep-seated leg veins. OBJECTIVE This study investigated the effectiveness and safety of long-pulsed Nd : YAG laser to treat alae nasae and nasal tip telangiectasia. METHODS Twelve patients were evaluated in a prospective IRB approved study. They had a history of previous unsatisfactory treatments with pulsed dye las...

BACKGROUND Nepalese population with Fitzpatrick skin types III-V has high prevalence of pigmentary disorders and it is a growing cosmetic concern. Q-Switched Neodymium- Doped Yttrium Aluminum Garnet (QS Nd-YAG) laser is an efficacious tool in the treatment of pigment disorders. OBJECTIVE To highlight the efficacy and safety profile of various pigment disorders. METHODS A prospective study d...

PURPOSE High-energy lasers have been proposed as an alternative to the conventional surgical drill in oral and maxillofacial surgery. The aims of this study were to compare thermal changes of the bone surface, procedure time, and volume of the removed bone after drilling with an erbium (Er):yttrium-aluminum-garnet (YAG) laser versus a low-speed surgical drill. The bone sections were observed un...

conclusions the patient reported that he did not feel pain or discomfort throughout the intervention. follow-up visits performed after one, three, six, twelve, and sixteen months demonstrated vitality of the tooth the absence of complications, as well as good esthetic results. laser technology may be used in the treatment of traumatic anterior teeth injury with advantages in terms of quality of...

Erbium-doped solid-state laser systems have become an established tool in dentistry. The two most commonly used Erbium lasers in dentistry are Er:YAG and Er,Cr:YSGG, with a subtle but important difference in their respective laser wavelengths. There is also an important difference in the type of technology they utilize to energize the flashlamps. The conventional PFN (Pulse Forming Network) pul...

We present our recent advances in the use of pulsed laser deposition (PLD) to fabricate active gain elements for use as amplifiers and laser oscillators. Record output powers exceeding 16 W and slope efficiencies of 70% are reported for optimized epitaxial growth of Yb(7.5%):YAG on to YAG substrates. We show for the first time that the performance of PLD material can meet or even exceed that of...

BACKGROUND Patients with atrophic scars commonly seek treatment for their removal but are often concerned about the prolonged recovery, short-lived results, and/or ineffectiveness of available therapies. A novel treatment using a 1,550-nm erbium-doped fiber laser to induce fractional photothermolysis of treated skin has been used to resurface photodamaged skin but has not been studied previousl...

BACKGROUND Facial reticular blue veins are of esthetic concern. Most often these veins develop on the lower lids. The safest and most effective way of treatment is by vascular lasers. CASE REPORT We report on a successful reticular vein treatment using a long-pulsed 1064 nm Nd: YAG laser. We present a follow-up of 8 years with constant esthetic improvement without unwanted adverse events. C...

Acute and chronic experiments were carried out in 26 beagle dogs to study the safety and efficacy of Neodymium-Yag laser photocoagulation in the treatment of bleeding gastric lesions. Continuous high power (50-60 W) Neodymium-Yag laser photocoagulation applied to the exposed stomach of the dog produced evaporation lesions that reached the muscle layer after six to 10 seconds and caused free per...

BACKGROUND A serum-free in vitro model was used to determine the effect of combined carbon dioxide (CO2) and erbium (Er):YAG laser (Derma K; ESC/Sharplan Medical Systems, Yokneam, Israel) irradiation on keloid-producing fibroblasts (KFs) from 2 distinct facial sites. Transforming growth factor beta1 (TGF-beta1) and basic fibroblast growth factor (bFGF) play an integral part in wound healing and...
