1. 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 �

2. Clinical evaluation of two materials in the restoration of abfraction lesions
Abstract Aim: To evaluate the clinical performance of a composite resin (CR) and a resin-modified glass-ionomer cement (RMGIC) for the treatment of abfraction lesions. Methods: Thirty patients with abfraction lesions in at least two premolar teeth were selected and invited to participate in this study. All restorations were made within the same clinical

3. Marginal integrity of restorations produced with a model composite based on polyhedral oligomeric silsesquioxane (POSS)
Marginal integrity is one of the most crucial aspects involved in the clinical longevity of resin composite restorations. Objective To analyze the marginal integrity of restorations produced with a model composite based on polyhedral oligomeric silsesquioxane (POSS). Material and Methods A base composite (B) was produced with an organic matrix with UDMA/

4. Influence of polymeric matrix on the physical and chemical properties of experimental composites
Nowadays, the main reasons for replacement of resin-based composite restorations are fracture or problems with the integrity of their interface, such as marginal staining, microleakage, or secondary caries. The aim of the present study was to evaluate the influence of the organic matrix on polymerization stress (PS), degree of conversion (DC), elastic modulu

5. Impact of adhesive and photoactivation method on sealant integrity and polymer network formation
We evaluated the influence of photoactivation method and hydrophobic resin (HR) application on the marginal and internal adaptation, hardness (KHN), and crosslink density (CLD) of a resin-based fissure sealant. Model fissures were created in bovine enamel fragments (n = 10) and sealed using one of the following protocols: no adhesive system + photoactivation

6. A 3-year follow-up study of all-ceramic single and multiple crowns performed in a private practice: a prospective case series
OBJECTIVES: Zirconia-based prostheses are commonly used for aesthetic crown and fixed restorations, although follow-up data are limited, especially for implant-supported crowns. The aim of this study was to evaluate the threeyear clinical results of the installation of 463 zirconia core crowns by a general dental private practice. METHODS: This study followe

8. The influence of habitat integrity and physical-chemical water variables on the structure of aquatic and semi-aquatic Heteroptera
This work aimed to assess the effect of certain physical-chemical variables and the Habitat Integrity Index (HII) have on an aquatic and semi-aquatic heteropteran community. We collected in five streams (from 1st to 4th order) that differed in habitat integrity, in order to test 1) whether heteropteran richness decreases with the Habitat Integrity Index; and

9. Biocombustíveis, controvérsia agrícola na economia do petróleo: o caso do etanol no Cerrado / .
In the controversial debate about the impacts of biofuels, Brazil has been trying to sustain a supposed immunity. The argument rests on the extraordinary abundance of degraded grazing land, sufficiently capable of accommodating the expansion of sugarcane without threatening food security or compromising the integrity of ecosystems. Although the enormous adva

10. CAD/CAM Zirconia vs. slip-cast glass-infiltrated Alumina/Zirconia all-ceramic crowns: 2-year results of a randomized controlled clinical trial
The aim of this randomized controlled clinical trial was to compare the early clinical outcome of slip-cast glass-infiltrated Alumina/Zirconia and CAD/CAM Zirconia all-ceramic crowns. A total of 30 InCeram® Zirconia and Cercon® Zirconia crowns were fabricated and cemented with a glass ionomer cement in 20 patients. At baseline, 6-month, 1-year, and 2-year

11. Efeito do tempo e tipo de fotoativação e da ciclagem mecanica e termica na infiltração marginal de restaurações adesivas / Effect of light polimerization mode, time and mechanical and thermal load cycling on microleakage in adhesive restorations
The maintenance of the bond integrity between tooth and resin systems is important for the clinical success of composite resin restorations. Thus, the aim of this "in vitro" study composed of two manuscripts, was to evaluate the microleakage of Class II dental restorations: 1) made with an adhesive system and a dental composite, varying light curing time and

12. Influence of thermal stress on marginal integrity of restorative materials
The aim of this study was to evaluate the influence of thermal stress on the marginal integrity of restorative materials with different adhesive and thermal properties. Three hundred and sixty Class V cavities were prepared in buccal and lingual surfaces of 180 bovine incisors. Cervical and incisal walls were located in dentin and enamel, respectively. Speci
