4. A randomized clinical trial of cavity liners after selective caries removal: one-year follow-up
Abstract Alternatives for the treatment of caries disease, such as minimally invasive approaches, have been developed in recent years. Objective: To carry out clinical and radiographic evaluations of three cavity liners after selective caries removal. Methodology: Thirty-six primary molars with deep occlusal caries lesions without pulp involvement (from ch

5. Efeito do envelhecimento acelerado sobre as propriedades de microconcreto reforçado com fibras longas de sisal
Resumo Neste trabalho dois microconcretos, com e sem metacaulinita, foram dosados para produção de compósitos laminados reforçados com fibras longas de sisal. Para garantir uma matriz livre de hidróxido de cálcio foi determinado o teor ideal de metacaolinita por análise termogravimétrica de pastas com teores de substituição de 20%, 30% e 40 nas ida

7. Microstructure and hardness of cement pastes with mineral admixture
ABSTRACT Portland cement pastes are highly heterogeneous material and exhibits heterogeneous features over a wide range of length scales. Mechanical properties of microstructure can be determined using depth-sensing indentation. Coupled indentation/SEM technique can be used to location the indents and provides a way to determine the mechanical properties of

8. Crown discoloration promoted by materials used in regenerative endodontic procedures and effect of dental bleaching: spectrophotometric analysis
Abstract Regenerative endodontic procedure (REP) has been proposed as a new approach to treat immature permanent teeth. However, materials used in REP for root canal disinfection or cervical sealing may induce tooth discoloration. Objectives To assess tooth crown’s color after intracanal treatment with triple antibiotic paste (TAP) or calcium hydroxide (

9. Doping technique in the interfacial transition zone between paste and lateritic aggregate for the production of structural concretes
This paper discusses the use of doping technique in the interfacial transition zone (ITZ) between Portland cement paste and lateritic aggregates with the objective of promoting the implementation of structural concrete. Doping technique consists of establishing the initial impregnation of the aggregate with a high performance paste in order to improve its bi

10. Estudo da radiopacidade de materiais odontológicos indicados como base e forramento de restaurações. Análise através da radiografia digital / Study of the radiopacity of dental materials used as base and liner of restorations. Analysis by digital radiographic
Radiopacity is an important pre-requisite for base and liner materials, once it allows the professional to identify the presence of the material and makes its differentiation from the adjacent tooth structure possible. The aim of this study was to evaluate the radiopacity of liner and base materials and compare to the radiopacity of enamel, dentin and alumin

12. Subcutaneous tissue reaction to castor oil bean and calcium hydroxide in rats
Castor oil bean cement (COB) is a new material that has been used as an endodontic sealer, and is a candidate material for direct pulp capping. OBJECTIVE: The purpose of this study was to evaluate the biocompatibility of a new formulation of COB compared to calcium hydroxide cement (CH) and a control group without any material, in the subcutaneous tissue of
