2. Avaliação da eficácia do bochecho com solução de digluconato de clorexidina a 0,12% no controle dos microrganismos no processo de moldagem com hidrocoloide irreversível
Avaliou-se a eficácia do bochecho com solução de digluconato de clorexidina a 0,12% no controle dos microrganismos no processo de moldagem com hidrocoloide irreversível. Foram selecionados 21 pacientes divididos em dois grupos: no G1 controle realizou-se bochecho por 1min. com soro fisiológico e no G2 experimental o bochecho por 1min. foi feito com solu

3. Influence of the casting material on the dimensional accuracy of dental dies
The purpose of this study was to evaluate the dimensional accuracy of different materials used in the confection of dies. Two stainless steel standard models were confected. One of the models, which was 2 mm larger than the other model, was used to provide a uniform relief for the two-step putty-wash impression technique. Thirty impressions were obtained usi

4. Avaliação in vitro de materiais e técnicas de transferência em implantes múltiplos / In vitro evaluation of materials and tranfer techniques in multiple implants
Objectives: The aim of this study is to compare different materials and techniques used in multiple implant transfer impressions, measuring the gap between superstructure and the implants. Method: Four external hexagonal implants (Neodent, Curitiba, Brazil) were fixed in a master cast and over a superstrucure. Afterwards, the impressions were made using poly

5. Radiodensity evaluation of dental impression materials in comparison to tooth structures
In the most recent decades, several developments have been made on impression materials' composition, but there are very few radiodensity studies in the literature. It is expected that an acceptable degree of radiodensity would enable the detection of small fragments left inside gingival sulcus or root canals. OBJECTIVE: The aim of this study was to determin

6. Linear dimensional changes in plaster die models using different elastomeric materials
Dental impression is an important step in the preparation of prostheses since it provides the reproduction of anatomic and surface details of teeth and adjacent structures. The objective of this study was to evaluate the linear dimensional alterations in gypsum dies obtained with different elastomeric materials, using a resin coping impression technique with

7. SYNTHESIS AND CERAMIC PROCESSING OF ALUMINA AND ZIRCONIA BASED COMPOSITES INFILTRATED WITH GLASS PHASE FOR DENTAL APPLICATIONS / Síntese e processamento de compósitos á base de alumina e zircônia com infiltração de fase vítrea para aplicações odontológicas
The interest for the use of ceramic materials for dental applications started due to the good aesthetic appearance promoted by the similarity to natural teeth. However, the fragility of traditional ceramics was a limitation for their use in stress conditions. The development of alumina and zirconia based materials, that associate aesthetic results, biocompat

8. Avaliação dimensional de modelos de gesso em função de diferentes tecnicas e materiais de moldagem elastomericos / Dimensional evaluation of stone models in function of different techniques and elastomeric impression materials
O objetivo neste estudo foi medir e comparar a precisão dimensional de modelos de gesso confeccionados a partir de três técnicas de moldagem com dez diferentes elastômeros. Um modelo em cera, simulando um arco dental mandibular, teve retirados os dentes 44, 45 e 46 a fim de avaliar possíveis diferenças de precisão entre os lados direito e esquerdo, pe

9. Identificação dos microorganismos presentes na saliva, na coroa dental e no canal radicular de dentes indicados ao retratamento endodontico e analise da suscetibilidade antimicrobiana, dos fatores de virulencia e da diversidade genetica dos Enterococcus faecalis isolados / Identification of microorganism present in saliva, crown and root canal of endodontically treated teeth and analysis of antimicrobial susceptibility, virulence factors and diversity of clonal types of Enterococcus faecalis isolated
The aims of this study were: (a) to identify Enterococcus spp., Staphylococcus spp., Candida spp. and enterobacteria in saliva of patients with failure of the endodonticallytreated teeth, (b) to investigate the microbiota in the restorative material and within root canals of the same subjects, (c) to determine the antimicrobial susceptibility of E. faecalis

10. Estabilidade dimensional de modelos obtidos com poliéter e silicone de adição após desinfecção com ácido peracético e hipoclorito de sódio
The disinfection of dental impressions is an important procedure to prevent cross infection on dental office. The aim of this study was compare the dimensional stability of models obtained of three impressions materials after disinfection with 1% sodium hypochlorite and 0,2% peracetic acid (Sterilife, Lifemed). A master model with points at first right molar

11. Accuracy of stone casts obtained by different impression materials
Several impression materials are available in the Brazilian marketplace to be used in oral rehabilitation. The aim of this study was to compare the accuracy of different impression materials used for fixed partial dentures following the manufacturers' instructions. A master model representing a partially edentulous mandibular right hemi-arch segment whose te

12. Determinação das forças geradas por resinas acrílicas ativadas quimicamente durante o processo de transferência da posição de implantes Análise fotoelástica
The great number of laboratorial phases during implant-supported prostheses may contribute to deficient passivity fit. This misalignment could lead to screws relieves and also, the loss of osseointegration. Impression technique is an important step to be observed. Many materials and techniques are involved in this stage and acrylic resin is the most frequent
