25. Aging and food source effects on mandibular stylets teeth wear of phytophagous stink bug (Heteroptera: Pentatomidae)
Studies were conducted to test the effect of age and food sources on wear of the mandibular teeth of the phytophagous pentatomid, Euschistus heros (F.). The total length (µm) of the area bearing the mandibular teeth, the length of the 1st tooth, and the height of the 2nd tooth for teneral (< 1 day-old) adults were significantly greater than that of adults f

26. Influência da dentina sadia e afetada por cárie na resistência de união de sistemas adesivos e cimentos de ionômero de vidro em dentes decíduos - estudo in vitro / Influence of sound or caries-affected dentin on the bond strength of adhesive systems and glass ionomer cements in primary teeth an in vitro study
The aim of this study was to evaluate the influence of sound and caries-affected dentin of primary teeth restored with different materials, regarding bond strength and nanoleakage. Seventy two primary second molars received standardized occlusal preparations were randomly assigned in two groups. One group was nominated as sound dentin [SD] (n=36), and the ot

27. Reprodutibilidade de um índice para diagnóstico e avaliação da atividade de lesões de cárie dentária na dentição decídua / Reliability of a caries diagnostic and activity assessment criteria in the primary dentition
The aim of the present clinical study was to evaluate the inter-and intra-examiner reliability of a caries diagnostic criteria (Nyvad et al. 1999) in the deciduous dentition and to assess the mean examination time. This criteria is based on a combination of visual and tactile methods and differentiates between active and inactive caries lesions at both cavit

28. Abrasion wear resistance of different artificial teeth opposed to metal and composite antagonists
One of the most important properties of artificial teeth is the abrasion wear resistance, which is determinant in the maintenance of the rehabilitation's occlusal pattern. OBJECTIVES: This in vitro study aims to evaluate the abrasion wear resistance of 7 brands of artificial teeth opposed to two types of antagonists. MATERIAL AND METHODS: Seven groups were p

29. Effect of monomer content in the monomer-polymer proportion on complete denture teeth displacement / Efeito do conteudo de monomero na proporção monomero-polimero no deslocamento dental em protese total superior
The purpose of the study was to verify the linear displacement of the teeth in complete upper denture made with acrylic resin, with monomer content indicated by the manufacturer, with 25% in excess and 25% less, in the conventional and microwaves polymerization techniques. Thirty casts were made with type III stone plaster, based on silicone mould, represent

30. Influence of an experimental solution for complete denture cleaning on the physical properties of acrylic resins, artificial teeth and soft liners / Influência de uma solução experimental para higiene de próteses totais nas propriedades físicas e mecênicas de resinas acrílicas, dentes artificiais e reembasadores resilientes
This study evaluated conventional (RAC) and microwave-polymerized (RAM) acrylic resins, artificial teeth (Vipi, Biolux and Trilux) and soft liners (Elite Soft and Mucopren Soft) after immersion in 3 solutions: water, sodium hypochlorite 1%; experimental solution of Riccinus communis (RC). The Knoop hardness and color alteration of resins, and shore A hardnes

31. A influência da fonte fotoativadora e de diferentes produtos de uso profissional sobre o clareamento de dentes desvitalizados : estudo ex vivo / The influence of light source and different products for professional use on the bleaching of devitalized teeth : ex vivo study
There are controversies about the use of light sources to accelerate the bleaching agents in teeth submitted to endodontic treatment. The objective of this study was to analyse quantitatively the bleaching ability of different products for professional use, photoactivated or not, on bovine teeth stained artificially. Fifty bovine incisor were divided on five

32. Resistencia ao impacto da união dente-resina acrilica sob efeito da desinfecção simulada por energia de microondas / Effect of simulated microwave disinfection on bond strength of acry teeth and denture base resins
The aim of this study was to evaluate the effect of microwave disinfection in bond strength of acrylic teeth and a denture base resin. A hundred sixty rectangular wax patterns (30x15x5mm) were embedded in flasks with type III dental stone. After cristalization, the resulting moulds were filled with laboratorial silicone (Zetalabor), in which a molar acrylic

33. Eruption of deciduous teeth and early childhood caries: a longitudinal study / Erupção de dentes decíduos e cárie precoce da infância: estudo longitudinal
A erupção de dentes decíduos e a cárie precoce da infância (CPI) foram estudadas longitudinalmente, avaliando-se os dados clínicos obtidos a cada quatro meses, de um grupo de 135 bebês, dos 7 aos 35 meses de idade, de baixa condição socioeconômica do Município de Bauru - SP. Não houve diferenças estatisticamente significantes entre os gêneros n

34. Evaluation of bond strength and characterization of hybrid layer produced by an experimental adhesive based on hydrophobic methacrylate or dissolved in 10% and 30% ethanol, applied to ethanol-saturated dentin in a longevity study / Avaliação da resisténcia de união e caracterização da camada híbrida formada por adesivos experimentais a base de metacrilato hidrófobo ou solvatado em 10% e 30% de etanol, aplicados sobre dentina saturada com etanol em um estudo de longevi
The longevity of an adhesive interface is affected by the effects of hydrolytic degradation, which is associated with high water content in the dentin tissue. The hybridization of dentin with hydrophobic monomers in a water-free substrate could make the bond strength of these interfaces remain stable for an extended period of time. The aim of this study was

35. EFEITOS DE AGENTES CLAREADORES EXTERNOS NOS TECIDOS DENTÁRIOS E NA JUNÇÃO AMELOCEMENTÁRIA / Effects of external bleaching agents on dental tissues and the cementoenamel junction
Evaluate with a scanning electron microscope the alterations occurring in enamel, cementum and cementoenamel junction after the use of different external bleaching agents. Fifteen healthy pre-molars were sectioned in the middle with the aid of a cutting machine (Labcut 1010), in the longitudinal direction along the axis of the teeth, obtaining mesial and dis

36. Effect of ridge lap surface treatment and thermocycling on microtensile bond strength of acrylic teeth to denture base resins
Este estudo avaliou o efeito do tipo de resina de base (termo-polimerizada e polimerizada por microondas), tratamento da superfície de união (com e sem aplicação de metil metacrilato) e termociclagem sobre a resistência adesiva à microtração (RAµT) do dente artificial Biotone. A superfície cervical dos dentes foi desgastada para se obter superfíci
