1. MicroCT evaluation for CAD/CAM occlusal veneer fit using two materials and three cement space settings
Resumo Este estudo teve como objetivo avaliar o ajuste da restauração de facetas oclusais para dois materiais CAD/CAM com diferentes configurações de espaço de cimento, usando microCT. Foram feitos sessenta moldes de resina e divididos em dois grupos (n=30) de acordo com os materiais, (I): cerâmica pura híbrida, e (II): cerâmica de vidro de silicato

2. Alternative of Lower-Cost Glass-Ionomer Sealant in the Prevention of Caries Lesions in Brazilian Children
Abstract Objective: To compare retention, preventive effectiveness and longevity of two different high-viscosity glass-ionomer sealants Ketac Molar® and Maxxion R® in the sealing of erupting and out-of-occlusion first permanent molar in children aged 5-7 years. Material and Methods: Children with past caries experience with healthy erupting first permane

3. Addition of zirconium oxide to Biodentine increases radiopacity and does not alter its physicochemical and biological properties
Abstract Objectives: To evaluate the radiopacity of Biodentine (BD) and BD associated with 15% calcium tungstate (BDCaWO4) or zirconium oxide (BDZrO2), by using conventional and digital radiography systems, and their physicochemical and biological properties. Materials and Methods: Radiopacity was evaluated by taking radiographs of cement specimens (n=8) u

4. Influence of ceramic material, thickness of restoration and cement layer on stress distribution of occlusal veneers
Abstract The aim of this study was to evaluate stress distribution in an occlusal veneer according to the restorative material, restoration thickness, and cement layer thickness. A tridimensional model of a human maxillary first molar with an occlusal veneer preparation was constructed using a modeling software of finite element analysis. The model was repli

5. Caries progression in non-cavitated fissures after infiltrant application: a 3-year follow-up of a randomized controlled clinical trial
Abstract Objectives To evaluate the efficacy of a conservative treatment to prevent the progression of caries using an infiltrant on non-cavitated pit and fissures. Material and Methods This controlled clinical trial selected 23 volunteers with clinically and radiographically non-cavitated occlusal caries among patients presenting a “rather low” to �

6. Misfit and fracture load of implant-supported monolithic crowns in zirconia-reinforced lithium silicate
Abstract Zirconia-reinforced lithium silicate (ZLS) is a ceramic that promises to have better mechanical properties than other materials with the same indications as well as improved adaptation and fracture strength. Objective In this study, marginal and internal misfit and fracture load with and without thermal-mechanical aging (TMA) of monolithic ZLS and

7. Effect of new innovative restorative carbomised glass cement on intrapulpal temperature rise: an ex-vivo study
Abstract This study aimed to evaluate the temperature changes that occurred in the pulp chamber when using GCP Glass Carbomer Fill (GCP) and two different resin-modified glass-ionomer (RGI) restorative materials at different dentin thicknesses. A standardized Class I occlusal cavity with 1 mm or 2 mm dentin thickness was prepared in the extracted human molar

8. Evaluation of an experimental rat model for comparative studies of bleaching agents
ABSTRACT Dental materials in general are tested in different animal models prior to the clinical use in humans, except for bleaching agents. Objectives To evaluate an experimental rat model for comparative studies of bleaching agents, by investigating the influence of different concentrations and application times of H2O2 gel in the pulp tissue during in-o

10. Management of painful temporomandibular joint clicking with different intraoral devices and counseling: a controlled study
Objective The benefit of the use of some intraoral devices in arthrogenous temporomandibular disorders (TMD) patients is still unknown. This study assessed the effectiveness of the partial use of intraoral devices and counseling in the management of patients with disc displacement with reduction (DDWR) and arthralgia. Materials and Methods A total of 60

11. Effects of coronal substrates and water storage on the microhardness of a resin cement used for luting ceramic crowns
Composite resin and metallic posts are the materials most employed for reconstruction of teeth presenting partial or total destruction of crowns. Resin-based cements have been widely used for cementation of ceramic crowns. The success of cementation depends on the achievement of adequate cement curing. Objectives: To evaluate the microhardness of Variolink

12. Effect of veneering material on the deformation suffered by implant-supported fixed prosthesis framework
Knowing how stresses are dissipated on the fixed implant-supported complex allows adequate treatment planning and better choice of the materials used for prosthesis fabrication. Objectives: The aim of this study was to evaluate the deformation suffered by cantilevered implant-supported fixed prostheses frameworks cast in silver-palladium alloy and coated wi
