Abstract The aim of this work is to validate the clinical efficacy of the high-power holmium:YAG laser with percutaneous nephrolithotripsy (PCNL) in combination with ultrasound lithotripsy for complicated renal calculi. From November 2006 to December 2007, 60 patients with complicated renal calculi were treated with PCNL, where an F24 standard renal access tract was established by percutaneous renal puncture under the guidance of B-mode ultrasound, and stones were fragmented and cleared by high-power holmium laser in combination with ultrasound under an F20.8 nephroscope. Of the 60 patients with complicated ...

This study aimed to evaluate a laser fluorescence device (the DIAGNOdent) and a visual classification system (ICDAS-II) for occlusal caries diagnosis. It also aimed to determine whether fluorescence measurements taken at the tooth surface correlate with the fluorescence measurements taken within the body of the lesion. The occlusal surfaces of 100 extracted permanent teeth were examined using ICDAS-II and DIAGNOdent (LF-tooth). Serial sections were made and lesion depth was assessed histologically. DIAGNOdent readings were also taken from the sections (LF-section). There were significant positive strong correlations be...

Low-level Er:YAG laser irradiation enhances osteoblast proliferation through activation of MAPK/ERKEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Although the use of high-level Er:YAG laser irradiation has been increasing in periodontal and peri-implant therapy, the effects of low-level Er:YAG laser on surrounding tissues and cells remain unclear. In the present study, the effects of low-level Er:YAG laser irradiation on osteoblast proliferation were investigated. Cells of the osteoblastic cell line MC3T3-E1 were treated with low-level Er:YAG laser irradiation with various combinations of laser settings (fluence 0.7–17.2 J/cm2) and in the absence or presence of culture medium during irradiation. On day 1 and/or day 3, cell proliferation...

Can Surgical Site Infection (SSI) be treated by photodynamic therapy (PDT)?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Surgical Site Infection is defined as an infection of the tissues within or around the surgical wound that develops within 30 days after an operation . Many such infections are initiated by pyogenic organisms which are implanted into the wound at operation. Alternatively the surgical wound can become secondarily contaminated and be invaded by pathogens. In either event the SSI becomes a major cause of protracted recovery, and/or disabling morbidity, which in some cases lead to fatal outcome, after an otherwise successful operation.

Abstract A biopsy is a surgical procedure performed to establish a clear diagnosis of a lesion in order to clarify a clinical diagnostic suspicion. During a biopsy procedure it is fundamental to maintain safe and readable cut margins in order to permit histological visualization of possible marginal infiltrations or malignant transformation of a lesion. The aim of this study was to evaluate the histological peripheral damage caused by application of a KTP (potassium titanium phosphate) laser during oral soft tissue biopsy procedures. A KTP laser (λ 532 nm) at different power settings and fluences was u...

Abstract In vitro studies have provided conflicting evidence of temperature changes in the tooth pulp chamber after low-level laser irradiation of the tooth surface. The present study was an in vitro evaluation of temperature increases in the human tooth pulp chamber after diode laser irradiation (GaAlAs, λ = 808 nm) using different power densities. Twelve human teeth (three incisors, three canines, three premolars and three molars) were sectioned in the cervical third of the root and enlarged for the introduction of a thermocouple into the pulp chamber.

In conclusion, we found strong evidence that all EVLA procedures in blood filled veins deposit a heavily absorbing hot layer of carbonized blood on the fibre tip, with concomitant tip damage. This major EVLA mechanism is unlikely to have much wavelength dependence at similar delivered energies per centimetre of vein. Optical–thermal interaction between the vein wall and the transmitted laser light depends on wavelength.

Vision starts with a camera of sorts, for people this is the human eye. Just like a camera, light enters an optical system and is focused with some optics onto the retina where it is transformed into electrical impulses that are received by a big computer processor we call "the brain." In cameras it is all about the quality of the optics, the shape of the optics, and the size of the optics to get enough light into the camera for the film, or the sensor to be able to transform the light into electrical impulses. Our retina is a much better light sensor than most cameras and certainly more compact...

Comparative effects of wavelengths of low-power laser in regeneration of sciatic nerve in rats following crushing lesionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Peripheral nerves are structures that, when damaged, can result in significant motor and sensory disabilities. Several studies have used therapeutic resources with the aim of promoting early nerve regeneration, such as the use of low-power laser. However, this laser therapy does not represent a consensus regarding the methodology, thus yielding controversial conclusions. The objective of our study was to investigate, by functional evaluation, the comparative effects of low-power laser (660 nm and 830 nm) on sciatic nerve regeneration following crushing injuries.

Although as with any medical procedure their are risks and complications, for the vast majority of patients undergoing this procedure, the vision is restored to normal levels virtually overnight. Despite this fact, many potential LASIK candidates are cautious due to their previous experience with contact lenses. This is the secret question...

Sally Ibbotson and Alexis Sidoroff are to be congratulated on their clear and concise accounts of the place of Photodynamic Therapy (PDT) in the treatment of cutaneous pathology.
