1. Avaliação do efeito de diferentes lasers de alta intensidade no tratamento de superfície da cerâmica Y-TZP pré e pós sinterização / Effect evaluation of different high-intensity lasers on the surface treatment of Y-TZP ceramic before and after sintering
O objetivo deste estudo foi avaliar os efeitos dos lasers de Nd:YAG, CO2 e Er,Cr:YSGG no tratamento de superfície da cerâmica Y-TZP antes e depois da sinterização final, por meio de Microscopia Eletrônica de Varredura (MEV), mensuração da rugosidade de superfície (Ra) e teste de resistência adesiva por microcisalhamento (RAD). Para tanto, barras de

2. CO2, Er: YAG and Nd:YAG lasers in endodontic surgery
OBJECTIVES: CO2, Er:YAG and Nd:YAG lasers have been used in endodontic surgery. This in vitro study evaluated 1% Rhodamine B dye penetration using computer-assisted morphometry (ImageTool Software®) of 108 endodontically treated human permanent canines. MATERIAL AND METHODS: Teeth were divided into 9 groups according to the technique used: A: 90-degree apic

3. Avaliação in vitro e in situ da eficácia de diferentes lasers no aumento da resistência ácida do esmalte em regiões de sulcos e fissuras / In vitro and in situ assessment of lasers to increase enamel acid resistance on the pits and fissures surface.
The aim of this study was to assess in vitro and in situ the lasers Er:YAG, Nd:YAG e CO2 in preventing enamel demineralization on the pits and fissures surface. For the in vitro study 45 occlusal enamel blocks were randomly divided into 3 groups in according with the treatment: G1 - Er:YAG; G2 - Nd:YAG; G3 - CO2. Treatments were made only on a half of the sp

4. Análise in vitro da presença de infiltração apical em dentes apicectomizados com técnica convencional e com o Laser de Er:YAG.
The high number of failure in Endodontic Surgery is mostly correlated to the lack of an adequate marginal sealing after an apicoectomy, compromising the maintenance of an environment not vulnerable to bacterial penetration. The aim of the present investigation was to evaluate (in vitro), by means of Methilene blue 2 %, the apical permeability of teeth after

5. Efeitos nÃo lineares em lÃquidos orgÃnicos e meios nanoestruturados
In this thesis, we report studies of nonlinear transverse effects in organic liquids, carbon disulfide (CS2) and dimetil sulfoxide (DMSO), and of fluorescent emission effects in nanostructured media, more specifically, frequency upconversion in erbium doped barium titanate nanocrystals (BaTiO3:Er3+) and laserlike emission from inverted opal nanostructure of
