13. Effect of Dental Restorative Material Type and Shade on Characteristics of Two-Layer Dental Composite Systems
Abstract The purpose of this study was to investigate the effects of shade and material type and shape in dental polymer composites on the hardness and shrinkage stress of bulk and two-layered restoration systems. For this purpose, some bulk and layered specimens from three different shades of dental materials were prepared and light-cured. The experiments w

14. Water interaction and bond strength to dentin of dye-labelled adhesive as a function of the addition of rhodamine B
ABSTRACT Objective This study investigated the effect of the fluorescent dye rhodamine B (RB) for interfacial micromorphology analysis of dental composite restorations on water sorption/solubility (WS/WSL) and microtensile bond strength to dentin (µTBS) of a 3-step total etch and a 2-step self-etch adhesive system. Material and Methods The adhesives Adp

15. Risk factors for dental caries in children with developmental disabilities
Abstract The aim of the present study was to investigate risk factors for dental caries in children with developmental disabilities who were treated at a clinical reference service for patients with special needs in Belo Horizonte, MG, Brazil. This is a retrospective cohort study that evaluated 401 dental charts of individuals without dental caries or restor

17. Recovering Streptococcus mutans over restorations by the tray technique: a randomized clinical study
AIM: To correlate the tray technique for isolation and counting of Streptococcus mutans over dental restoration with the toothpick technique. METHODS: Forty 18-50-year-old patients of both genders with high cariogenic risk were selected. Inclusion criteria were: occlusal restoration evaluated as alpha, according to the Ryge's criteria (examiner' Cohen-Kappa

18. Cost analysis of materials used in Class III, IV and V composite resin restorations
AIM: To assess the total cost of direct and indirect materials used in Class III, IV and V composite resin direct restorations. METHODS: The calculation of costs was based on the method of variable costing system. A list of the materials was obtained by a panel of experts and based on the excellence standards established in the literature for dental team tre

19. Influence of photo-activation source on enamel demineralization around restorative materials
This study evaluated the effects of the photoactivation source and restorative material on the development of caries-like lesions on human enamel after an in vitro pH challenge. Enamel cavities were prepared in 36 blocks, which were assigned to two groups according to the restorative material: resin-modified glass ionomer (RMGI) and composite resin (CR). Sam

20. 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

21. Selamento de lesões de cárie em dentina de dentes decíduos / Sealing dentinal carious lesions in primary teeth
O objetivo do presente estudo in vivo foi verificar o efeito do selante de fossas e fissuras na paralisação de lesões de cárie em metade externa de dentina comparado ao tratamento restaurador com resina composta em dentes decíduos. Quarenta e dois molares decíduos de 36 pacientes foram selecionados. Os critérios de inclusão envolveram clinicamente a

22. Inflammatory root resorption in primary molars: prevalence and associated factors
This study aimed at determining the prevalence of inflammatory root resorption and associated factors in 1068 primary mandibular molars in 453 children 3 to 12 years of age. Age, dental history and medical history were recorded using a questionnaire administered to the children's parents/caregivers. Previously trained and calibrated examiners assessed radiog

23. Clinical strategies for esthetic excellence in anterior tooth restorations: understanding color and composite resin selection
Direct composite resin restorations have become a viable alternative for patients that require anterior restorative procedures to be integrated to the other teeth that compose the smile, especially for presenting satisfactory esthetic results and minimum wear of the dental structure. Technological evolution along with a better understanding of the behavior o

24. Desgaste abrasivo de uma resina composta, através de três diferentes métodos (disco retificado, escovação e nanodurômetro) / Abrasive wear of a composite resin, using three different methods (ground disc, toothbrushing and nanodurometer)
Neste estudo, foi avaliada a resistência ao desgaste abrasivo de uma resina composta, através de três diferentes métodos: do disco retificado, por escovação e do nanodurômetro. Nos dois primeiros métodos, foram utilizados 20 espécimes da resina Filtek Z250 (10 da cor Incisal e 10 da cor C4, ambos fotopolimerizados por 30 segundos cada) e 10 de polim
