Bacteriological profile in conjunctival, lacrimal sac, and nasal specimens and conjunctival normalization time following external, endoscopic, and transcanalicular multidiode laser dacryocystorhinostomy

Arq. bras. oftalmol; 79 (3), 2016
ABSTRACT Purpose: To compare the conjunctival, lacrimal sac, and nasal flora cultures and conjunctival normalization time following external (EX-), endoscopic (EN-), and transcanalicular multidiode laser (TC-) dacryocystorhinostomy (DCR) and to evaluate the relationship between culture positivity and su...

Activation of C-fiber nociceptors by low-power diode laser

Arq. neuropsiquiatr; 74 (3), 2016
ABSTRACT Objective The evaluation of selective activation of C-fibers to record evoked potentials using the association of low-power diode laser (810 nm), tiny-area stimulation and skin-blackening. Method Laser-evoked potentials (LEPs) were obtained from 20 healthy young subjects. An aluminum plate w...

Development of an ex vivo model of endovenous laser ablation of the great saphenous vein in a pilot study

Acta cir. bras; 31 (3), 2016
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...

Effect of irradiation with different laser wavelengths on oxidative stress of non-hepatectomized rats

Acta cir. bras; 31 (supl.1), 2016
PURPOSE: To assess the effect of two laser wavelengths, either separate or combined, on intact rat livers. METHOD: Nineteen male Wistar rats (200-300 g) were submitted to laser irradiation at 5 different sites on the liver surface.Wavelengths 660 and 780 nm were used, with a dose of irradiation of 60 J/...

Low Intensity laser therapy in patients with burning mouth syndrome: a randomized, placebo-controlled study

Braz. oral res. (Online); 30 (1), 2016
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...

Clinical effect of photodynamic therapy on primary carious dentin after partial caries removal

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was conducted to assess the clinical effect of photodynamic therapy (PDT) in the decontamination of the deep dentin of deciduous molars submitted to partial removal of carious tissue. After cavity preparation, dentin samples were taken from the pulp wall of nineteen deciduous molars b...

Effects of different desensitizing treatments on root dentin permeability

Braz. oral res. (Online); 30 (1), 2016
Abstract The objective of this study was to evaluate the effects of diode laser and a desensitizing dentifrice on dentin permeability. Fifty-two root dentin fragments were obtained (5 × 5mm) and treated with 24% EDTA gel. The samples were divided into 4 groups (n = 13): G1, control (no treatment); G2, d...

Low-level laser therapy effects on pain perception related to the use of orthodontic elastomeric separators

INTRODUCTION: Some patients refer to pre-banding orthodontic separation as a painful orthodontic procedure. Low-level laser therapy (LLLT) has been reported to have local analgesic effect. OBJECTIVE: The aim of this single-blind study was to investigate the perception of pain caused by orthodontic elasto...
