Lasers have become a popular tool in veterinary practice, particularly the carbon dioxide (CO2) laser. In humans, the CO2 laser is used most commonly in oral and maxillofacial soft tissue surgery due to its favorable interactions with oral soft tissues. Other types of lasers are better suited for use on hard tissues such as enamel and dentin. This article reviews the history of laser use, physi...

BACKGROUND Upper eyelid dermatochalasis is typically treated with excisional blepharoplasty. The role of the CO2 laser previously had been confined to that of a vaporizing, incisional, or hemostatic tool. Over the past several years, however, ablative CO2 laser skin resurfacing has been popularized as an adjunctive treatment to blepharoplasty to minimize periorbital rhytides through its vaporiz...

BACKGROUND AND OBJECTIVE A previous study [Moritz et al., Z Stomatol 1996; 93:451-454] had shown that favourable results in direct pulp capping could be achieved using a continuous wave CO2 laser in addition to the conventional calcium hydroxide dressing technique. In this study, these results are compared to those achieved using a CO2 laser working in superpulsed mode. STUDY DESIGN/MATERIALS...

Background and aims: Skin rejuvenation is one of high demand cosmetic interventions in Iran. Fractional CO2 Laser is a high power ablative laser which has variety of utilization in medicine including treatment of acne scars and rejuvenation. The aim of this study was to evaluate the safety, efficacy, and cost-effectiveness of Fractional CO2 Laser in comparison with other methods of rejuvenation...

Background & Aims: Lupoid (LL) and chronic leishmaniais (CCL) are variants of cutaneous leishmaniasis (CL) which are resistant to various treatments. The diseases are endemic in some developing countries such as Iran. A Variety of drugs with different effects have been suggested in recent decades. Carbon deoxide laser has been recently applied in the treatment of different dermatological diseas...

We investigated the angular dependence of atomic and ionic debris from CO2 and YAG laser-produced tin plasmas. Several diagnostic techniques were employed for this study including a Faraday cup, witness plates and subsequent x-ray photoelectron spectroscopic analysis, optical emission spectroscopy etc. It was found that the debris emission from the Nd:YAG laser-produced plasmas fell sharply fro...

The purpose of this study was to evaluate potential technical advantages of the CO2 laser technology in mini-open transforaminal lumbar interbody fusion (TLIF) surgeries and report our preliminary clinical data on the safety and clinical outcomes. There is currently no literature discussing the recently redeveloped CO2 laser technology application for lumbar fusion. Safety and clinical outcomes...

In the present investigation, H13 tool steel has been deposited on copper alloy substrate using both CO2 and diode laser. A detailed parametric analysis has been carried out in order to find out optimum processing zone for coating defect free H13 tool steel on copper alloy substrate. Followed by parametric optimization, the microstructure and microhardness of the deposited clads have been evalu...

BACKGROUND Ablative laser skin resurfacing with carbon dioxide (CO2) and erbium:yttrium-aluminum-garnet (Er:YAG) lasers has been popularized in recent years and their side effects individually reported. No prior study, however, has directly compared the relative healing times and complications rates between the two different systems. OBJECTIVE To evaluate and compare postoperative wound heali...

PURPOSE Dentin hypersensitivity is a potential threat to oral health. Laser irradiation may provide reliable and reproducible treatment but remains controversial. The present study aimed to evaluate the effects of CO2 or erbium-doped yttrium aluminium garnet (Er:YAG) laser therapy, and to assess mineral content. METHODS Eighteen human single-rooted teeth affected with advanced periodontitis w...
