1. Influência da limpeza mecânica com e sem o uso do microscópio operatório na resistência adesiva intrarradicular / Influence of mechanical cleaning with and without the use of the operating microscope in intraradicular adhesive strength
In endodontic treatment, there is an imperative need to restore the tooth, reestablishing its functions, since there is always a risk of recontamination of the root canal system and fractures. These risks are higher when there is loss of dental structure, requiring intraradicular posts to hold the restoration procedures in place. For the definitive and immed

2. Comparison between two tomographic sections in the diagnosis of external root resorption
OBJECTIVES: To assess the accuracy of coronal and sagittal CT sections to detect cavities simulating root resorption. MATERIAL AND METHODS: 60 mandibular incisors were embedded in plaster bases, and cavities with 0.6, 1.2 or 1.8 mm in diameter and 0.3, 0.6 or 0.9 mm in depth (small, medium and large cavities) were drilled on the buccal surfaces with high-spe

3. A influência da técnica do preparo cavitário utilizando laser Er: YAG e dos tipos de materiais restauradores na prevenção de cárie secundária
The influence of the cavity preparation technique and the types of restorative materials containing fluorides in the prevention of the secondary caries lesions was evaluated in this in vitro study. In a logic sequence the subject was approach by four manuscripts. The first study made a bibliographic revision about the laser employment in the prevention of th

4. Avaliação da retenção de pinos de fibra de vidro reembasados (pinos anatomicos) e não reembasados cimentados em diferentes condições / Evaluation of relined (anatomic post) and non relined fiber glass posts retention cemented in different conditions
This study evaluated the effect of the relining (anatomic posts), of type cements and the length of the luting on the retention of fiber glass posts. One hundred and eighty bovine incisors were selected, their coronary portion removed, and the canals endodontically treated. After endodontic treatment, the canals were extended with diamonds burs nº 4138 and

5. Histological evaluation of the human pulp response to different cavity instrumentation and restorative techniques / Avaliação histológica da resposta pulpar humana a diferentes técnicas de instrumentação cavitária e de restauração
Este estudo se propõe a analisar a resposta pulpar de dentes humanos a preparos cavitários de classe V, em função de duas diferentes técnicas de instrumentação e de duas diferentes técnicas de restauração. Para tal, cavidades classe V, nas superfícies vestibulares de 48 pré-molares hígidos de pacientes entre 11 e 25 anos, que estavam em tratamen

6. "Avaliação da desinfecção da dentina radicular em profundidade provocada pela irradiação do laser de diodo de alta potência" / Evaluation of root canal dentin desinfection in depth caused by high power diode laser irradiation.
The main cause for failure in Endodontics is the presence of microorganisms in root canal system. Enterococcus faecalis is a resistant microorganism presents in failure endodontic treatment. Therefore the disinfection plays fundamental rule in endodontic therapy. The laser irradiation presents properties that may improve the treatment success rates, reducing

8. Avaliação de diversos métodos para remoção da resina remanescente após descolagem de bráquetes ortodônticos.
The purpose of this study was to evaluate the alterations on enamel surface after the use of 5 different techniques to remove remnant resin after bracket debonding. The sample was constituted of 50 human premolars, extracted for orthodontic and periodontal purposes, whose vestibular faces were submitted to surface rugosimetric analysis, carried out at 3 dist

9. Analise da influencia da angulação horizontal e da compressão de imagens digitais no diagnostico de cavidades proximais
the main purpose on this work was to evaluate, subjectively, the influence of radiographic image compression on the diagnostic of incipient proximal lesions created artificially. Extracted teeth were submitted to artificial drilling in its proximal surfaces, with diamond burs, so they were submitted to radiographic incidences utilizing the DenOptix radiograp

11. Characteristics of the dentinária surface and Smear Layer formed by diamantados abrasive instruments: rotatory conventional, rotatory CVD and CVD for ultrasound. Study in vitro / Características da superfície dentinária e do esfregaço formado por instrumentos abrasivos diamantados: rotatório convencional, CVD rotatório e CVD por ultra-som. Estudo in vitro
Abrasive diamond instruments are a recent development, obtained through a technique called Chemical Vapor Deposition (CVD), used in ultrasound as a new possibility in dental cavity preparation. Traditionally, cavity preparations are made with conventional abrasive rotary diamond burs (IADR), forming a thick smear layer. Upon the development of new adhesive s

12. Influencia do tratamento de superficie na rugosidade Ra e dureza Vickers de ceramicas para cobertura incisal
The objective of this study was to evaluate the influence of surface treatment on surface roughness and Vickers hardness number of the eight dental enamel ceramics, after abrasive grinding and 4 surface treatments with polishing and/or glaze. Forty enamel ceramic disks with 8 mm in diameter and 2.0 mm thickness were made in bipartite metallic matrix for each
