Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to ...

Laser therapy has become one of the gold standards treatment in routine dentistry. In 1970s, CO2 lasers were first to be used oral surgery on soft tissues. Subsequently, other (Diode, Nd YAG, Er: Argon and Erbium) have also been periodontics, implantology, orthodontics restorative dentistry, as well for hard tissues, such bone, enamel dentin. The purpose this systematic review is analyze both t...

High-quality micro-lasers are key ingredients in non-linear optics, communication, sensing and low-threshold solar-pumped lasers. However, such micro-lasers exhibit negligible absorption of free-space broadband pump light. Recently, this limitation was lifted by cascade energy transfer, in which the absorption and quality factor are modulated with wavelength, enabling non-resonant pumping of hi...

introdouction: dentinal hypersensitivity (dh) is one of the most painful chronic problems reported in dental offices. various methods have been applied for the treatment of dh. however, majority of them are either ineffective or last for a short period of time. it has been reported that lasers, particularly neodymium- doped: yttrium aluminum garnet laser (nd: yag), can be helpful in the treatme...

All-solid-state passively Q-switched lasers have advantages that include simple structure, high peak power, and short sub-nanosecond pulse width. Potentially, these can be applied in multiple settings, such as miniature light sources, laser medical treatment, remote sensing, precision processing. Cr4+:YAG crystal is an ideal Q-switch material for all-solid-state owing to its thermal conductivit...

Objective: To evaluate therapy effects and capability to preserve adjacent tissues of bilateral focal prostate ablation using Nd: YAG laser a canine model. Methods: 24 male Beagle dogs aged 3.9-7.4 years and weighting 9.4-12.1 kg were used in this study. The dogs underwent single focal Nd: YAG ablation. Applied the reasonable prostatic ablation parameters screened in the study and set different...

introduction:  the aim of this in-vitro study was the evaluation of mperature changes due to irradiation of two different lasers used for the reduction of dentinal hypersensitivity and their effect on the pulp damage. the study was done for two dentin thicknesses.  methods:  twenty intact extracted third molars were prepared by longitudinal ground sectioning for 1 and 2 mm dentin thicknesses wh...

Background: Acne scar is the most common complication in acne that occurs about 49% of individuals. Fractional resurfacing lasers such as CO2 laser and erbium-doped yttrium aluminum garnet (Er: YAG) have been widely used for treatment give satisfying results complications pain, hyperpigmentation, infection, prolonged erythema, scarring. erbium: scandium gallium YSGG) solves previous techniques'...
