Introduction: A variety of laser treatments have been applied in numerous medical fields. In dentistry, are used for caries, root canals, and periodontal disease, as well surgical resection. Numerous reports recently published on the use lasers bone regeneration. If irradiation is found to promote activation metabolism, it might also be effective treatment, peri-implantitis, Therefore, present ...

BACKGROUND Striae distensae or stretch marks are atrophic linear dermal scars with epidermal atrophy. There are many therapeutic options for management, but no consistently effective modality is available yet. OBJECTIVE We compared the efficacy of 1064 nm long pulse (LP) Nd: YAG laser and 2940 nm variable square pulse (VSP) erbium: YAG laser in the treatment of striae distensae. METHODS Twe...

introduction: the aims of the present study were: [1] to evaluate whether erbium-doped: yttrium, aluminum and garnet (er: yag) laser could be a prophylactic methods against transient bacteremia during scaling and root planing (srp) [2] to confirm the efficacies of srp with er: yag laser by clinical and microbiologic evaluations. methods: twenty chronic periodontitis subjects were randomly treat...

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...

introduction: smear layer (sl) is produced as a result of mechanical instrumentation of the canal(s). despite the controversies regarding its removal, the evidence-based trend has shifted towards removing and eliminating the sl. different methods have been used to remove the sl and the aim of this in vitro study was to evaluate the ability of 17% ethylenediaminetetraacetic acid (edta), 18% etid...

Three kinds of apparatus of CO2 laser, that is, Medilaser S, NIIC Lasery 60 and NIIC Lasery Model 60Z, are used in our institute. Two kinds of apparatus of Nd-YAG laser, that is, Molectron Model 8000 and Medilas are utilized also. We have used CO2 lasers for removal of tumors in 75 brain tumor cases and 9 spinal cord tumor cases. CO2 lasers were also used for hemostasis in the muscle layer and ...

introduction: the purpose of the present study was to evaluate the different concentrations of sodium hypochlorite activated with laser in removing of the smear layer in the apical, middle, and coronal segments of root canal walls by scanning electron microscopy analysis. methods: sixty single-rooted human mandibular teeth were decoronated to a standardized length. the samples were prepared by ...

introduction: male urethral stricture is a complicated urologic disease that could be successfully treated using internal urethrotomy. laser internal urethrotomy has been used in many cases with favorable outcome in many studies. holmium: yag laser with its incisional properties on tissue is one of the laser types applied for internal urethrotomy. methods: we present a 19 year-old male with his...

OBJECTIVES The aim of this study was to determine the apical surface characteristics and presence of dental cracks in single-rooted premolars, resected 3.0 mm from the root apex, using the Er: YAG laser, tungsten carbide bur, and diamond-coated tip, by scanning electron microscopy (SEM). EXPERIMENTAL DESIGN Thirty single-rooted premolar teeth were collected. The instrumented and obturated tee...
