A variety of revision treatments available for managing different types scars, including laser therapy, chemical peeling, cryotherapy, dermabrasion, soft tissue augmentation, intralesional steroid injection, and surgical excision. Rhytides, dyschromias, specific kinds scars are among the epidermal dermal lesions that successfully treated using erbium YAG lasers. In this study, use Erbium to tre...

The use of lasers has been suggested for orthodontists to fabricate or repair orthodontic appliances by welding metals directly in the mouth. This work aimed to evaluate the temperature changes in the pulp chamber during welding of an orthodontic wire to an orthodontic molar band using Nd : YAG laser in vitro. A freshly extracted human third molar with eliminated pulpal tissues was used. J-type...

Transscleral ruby cyclocoagulation has been successfully used to lower intraocular pressure. The recent commercial availability of Nd-YAG lasers with a thermal mode provides a possible alternative by which to perform this procedure. We treated one eye of seven pigmented rabbits using the thermal mode of the Nd-YAG laser. The intraocular pressures were followed up for three months. The treated e...

Dual-pulse laser-induced breakdown spectroscopy (LIBS) provides improved sensitivity compared to conventional single-pulse LIBS. We used a combination of Nd: yttrium aluminum garnet (YAG) and CO2 lasers to improve the sensitivity of LIBS. Significant emission intensity enhancement is noticed for both excited neutral lines and ionic lines for dual-pulse LIBS compared to single-pulse LIBS. Howeve...

Starting from the optical properties of laser beams, the requirements of optical systems for manipulating laser radiation in industrial applications are derived. The relevant parameters, relations to the diffraction limit and the state-of-the-art design techniques are discussed. The three important types of lasers for use in industrial materials processing operate at wavelengths ranging from th...

Because of their many advantages, lasers have become indispensable in OMS as a modality for soft tissue surgery. Based on manufacturer estimates, approximately 10% to 20% of all oral and maxillofacial surgeons have one or more lasers in their offices, and most surgeons have access to lasers in the hospital. Lasers not only enhance the current surgical options for treatment, but also have expand...
