Thermal damage patterns of diode hair-removal lasers according to various skin types and hair densities and colors: a simulation study.

Background And Objective: It is important to prevent unwanted side effects of diode hair-removal lasers especially in dark skin tones. This study simulates the thermal damage patterns caused by diode hair-removal lasers in different skin types, hair colors, and hair densities.

Materials And Methods: LITCIT software has been used with the tissue modeled as two components, the skin and the hair.

Histological evaluation of drill fragments obtained during osteoid osteoma radiofrequency ablation.

Objective: Osteoid osteoma (OO) is a benign bone tumor diagnosed mainly on the basis of the patient's history and radiological data. Histological evaluation may not be available before treatment. The aim of this study was to assess the diagnostic value of a histological evaluation of the bone fragments obtained during radiofrequency ablation (RFA).

Radiofrequency ablation of osteoid osteoma in atypical locations: a case series.

Background: Osteoid osteoma has a nidus surrounded by sclerotic bone with a size usually less than 20 mm. Its diagnosis is made on typical presentation of nocturnal pain and imaging findings. Excision of the niduses, which are often small and difficult to precisely identify, sometimes may result in resection of surrounding normal bone.

Relieving pain in minor aphthous stomatitis by a single session of non-thermal carbon dioxide laser irradiation.

This randomized controlled clinical trial was designed to evaluate the efficacy of single-session, non-thermal, carbon dioxide (CO(2)) laser irradiation in relieving the pain of minor recurrent aphthous stomatitis (miRAS) as a prototype of painful oral ulcers. Fifteen patients, each with two discrete aphthous ulcers, were included. One of the ulcers was randomly allocated to be treated with CO(2) laser (1 W of power in de-focused continuous mode) and the other one served as a placebo.
