1. Immediate laser-induced hemostasis in anticoagulated rats subjected to oral soft tissue surgery: a double-blind study
Abstract Given the growing trend towards medical indications for continuous use of anticoagulants, the number of patients on these medications continues to rise. The management of patients on oral anticoagulants requiring oral surgical procedures has aroused much controversy. Changes in an anticoagulation regimen are associated with an increased risk of thro

2. Effect of a cordless retraction paste on titanium surface: a topographic, chemical and biocompatibility evaluation
Good exposure of the preparation margins and haemostasis in the sulcular gingiva are necessary for accurate impressions to produce precise restorations. The use of cordless retraction paste material in implant dentistry is a relatively novel application. However, few studies have been conducted on the use of retraction pastes and their possible interaction w

3. Influência do uso do laser na prevenção da cárie radicular / Influence of laser irradiation on root caries prevention
Objetivo: Este estudo avaliou a influência do uso de diferentes lasers, associados ou não à aplicação de fluoreto de sódio, na prevenção da cárie radicular. Materiais e Método: Para este estudo, 128 espécimes de dentina radicular humana (4,25mm X 4,25mm e 3,00mm de espessura) foram divididos aleatoriamente em 8 grupos: (G1=nenhum tratamento, G2=ap

4. Radiographic inspection of porosity in Ti-6Al-4V laser-welded joints
Widely used in dentistry, Ti-6Al-4V alloy is difficult to cast and solder, as it frequently exhibits pores inside the structure. This study was conducted to evaluate the effect of joint openings and diameters of laser-welded joints executed in Ti-6Al-4V structures on the presence of pores as checked by radiographic procedures. Sixty dumbbell rods with centra

5. Avaliação do substrato dentinário irradiado com laser de Er:YAG : resistência de união, padrão de fratura e análise ultramorfológica / Evaluation of dentin irradiated with Er:YAG laser : bond strength, failure pattern and ultramorphology analysis
The Er:YAG laser has been widely used in Dentistry and because its ability to remove mineralized dental tissues, it is indicate to be used in Operative Dentistry. As the Er:YAG laser is recent, little is known about the consequences of dental tissues irradiation and their effects on adhesive restorative procedures. Thus, the objectives of this study were to

6. Espectroscopia de fluorescência para detecção de lesões potencialmente malignas e carcinoma epidermóide da cavidade oral : estudo prospectivo / Fluorescence spectroscopy for detection of premalignant lesions and squamous cell carcinoma of the oral cavity : prospective study
Oral cancer is a public health problem with high incidence in the Brazilian population. The affected patient usually presents for clinical investigation, with advanced stage disease, the consequence of this delay is a reduction in survival rates. Given this, its essential to detect oral cancer in early stages. Fluorescence spectroscopy is a non-invasive di

7. Análise morfológica e da resistência adesiva dos tecidos dentais duros irradiados com lasers de pulsos ultracurtos / Evaluation of dental hard tissues irradiated with ultra-short pulsed lasers. Influence on surface morphology and microtensile bond strength
The development of restorative dentistry has reached the era of esthetic adhesive restorations and minimally invasive approach, for which innovative techniques and advanced materials are constantly introduced. Conservative techniques aim not only to remove carious dental substrate, but also to prepare cavity surfaces for adhesive restoration. The main object

9. Avaliação do uso do laser e processos fotodinâmicos na estimulação e crescimento celular de osteoblastos. Avaliação fotofísica e fotobiológica na presença e ausência de fármacos fotossensíveis / Evaluation of the use of laser and photodynamic processes in cell growth and stimulation of osteoblasts. Evaluation photophysical and photobiology in the presence and absence of drugs designed
The laser is a source of non ionizing radiation highly concentrated and coherent that in contact with different tissues induce thermal, photochemical and non-linear effects according to the type of the laser. Currently, the laser has been used routinely in many areas of science, as well as in medicine and dentistry. The treatments using laser radiation of lo

10. Efeito da irradiação do laser diodo 980 nm na microdureza da dentina radicular tratada previamente com diferentes soluções irrigantes / Effect of irradiation with diode laser (980 nm) on microhardness of root dentin previously treated with different irrigating solutions
The purpose of the present study was to evaluate, in vitro, the effect of 980 nm diode laser irradiation, in potencies of 1.5 and 3.0 W and 100 Hz frequency, on microhardness of radicular dentine in different depths. Seventy two roots of human canines were instrumented and randomly distributed into 3 groups (n=24), according to the irrigating solution used i
