1. O que é pericoronarite? É necessária a exodontia?
A pericoronarite é um processo infeccioso agudo caracterizado por inflamação do tecido gengival que recobre parcialmente um dente retido
. Os terceiros molares inferiores são os dentes mais comumente afetados
.
O tratamento inicial se dá com o uso de medicações analgésicas para alívio da dor e bochechos antissépticos com clorex

3. HOTSPOT STABILIZATION OF GOLD NANOPARTICLES FOR APPLICATION OF QUANTITATIVE SERS IN BIOANALYTICAL SYSTEMS
A complete procedure including synthesizing gold nanoparticles and further hotspots stabilization is presented. Colloidal gold synthesis followed a citrate reducing reaction, then, an ideal condition for SERS enhancement with quantitative purposes was reached by searching equilibrium between salt- and analyte-induced aggregation. Under this condition, a mild

6. Head loss in laser-perforated thin-walled polyethylene pipes for irrigation
RESUMO Para reduzir custos fixos e operacionais em sistemas de irrigação pressurizados são produzidos tubos de polietileno com pequena espessura de parede, com orifícios de descarga perfurados a laser, que operam a baixas pressões (até 100 kPa). A caracterização hidráulica desses materiais é essencial para o dimensionamento dos sistemas de irrigaç

7. Effect of low power laser in biomodulation of cultured osteoblastic cells of Wistar rats
Abstract Purpose: To analyze aspects of the biomodulating effect of light in biological tissues, bone cells from surgical explants of the femur of rats were irradiated with low intensity laser. Methods: Bone cells were cultured and irradiated with LASER light (GaAlAs). Growth, cell viability, mineralized matrix formation, total protein dosage, immunostim

8. Analysis of laser therapy effects in Sporothrix schenckii inactivation in vivo
Abstract Introduction Sporotrichosis is a common disease in tropical regions, caused by the fungus Sporothrix schenckii, affecting mainly rural workers and in direct contact with animals. Although treatment by indiscriminate use of oral antifungal drugs gives rise resistant isolates, leading to therapeutic failures and no remission of the disease. To evalu

9. Surface Modification of Ti6Al4V Alloy by Pulsed Lasers: Microstructure and Hydrophobic Behavior
In many aerospace applications, it is important to produce hydro-repellent surfaces because water and ice accumulation could lead to malfunctioning of the part or component with a potential critical failure. In this study, it was investigated the texturing of a titanium alloy (Ti6Al4V) by applying a pulsed Nd:YAG laser, aimed at the surface characterization

10. Low Intensity laser therapy in patients with burning mouth syndrome: a randomized, placebo-controlled study
Abstract The aim of this study was to assess the effectiveness of low intensity laser therapy in patients with Burning Mouth Syndrome (BMS). Thirty BMS subjects were randomized into two groups – Laser (LG) and Placebo (CG). Seven patients dropped out, leaving 13 patients in LG and 10 patients in CG. Each patient received 4 irradiations (laser or placebo) t

12. Development of an ex vivo model of endovenous laser ablation of the great saphenous vein in a pilot study
ABSTRACT PURPOSE: To develop an ex vivo model for the analysis of macroscopic, histological and immunohistochemical changes after experimental endovenous laser ablation (EVLA) of the great saphenous vein (GSV). METHODS: We describe a model produced with glass tubes and introducer sheaths to mimic the physiological conditions of EVLA procedures, such as t
