27. Análise fotoelástica da tensão de contração da polimerização de compósitos resinosos sob influência de técnicas restauradoras / Photoelastic analysis of polymerization shrinkage stress of composites under the influence of restorative techniques
Polymerization shrinkage stress is an undesirable and inevitable characteristic of adhesive restorations. It is important to understand the stress distribution to improve the clinical effectiveness of resin composite restoration. Chapter 1: The aim was to evaluate the polymerization shrinkage stress and degree of conversion of a resin composite material subm

28. Influência da espessura da resina de baixa viscosidade e da técnica restauradora na infiltração marginal em restaurações realizadas com compósito dental / Influence of the thickness of two flowable composite resins and the restorative technique on microleakage of simulated class II composite resin restorations
O objetivo deste estudo in vitro foi avaliar quantitativamente a infiltração marginal ao redor de restaurações dentais, realizadas com compósito resinoso microhíbrido, variando a espessura, a resina de baixa viscosidade e a técnica restauradora. As superfícies proximais de cento e trinta incisivos bovinos foram preparadas e divididas de acordo com a

29. Effects of resin luting agents and 1% NaOCl on the marginal fit of indirect composite restorations in primary teeth
OBJECTIVE: The purpose of this study was to provide information regarding the marginal adaptation of composite resin onlays in primary teeth previously treated with 1% sodium hypochlorite (NaOCl) (pulp irrigant) using two different resin luting agents. MATERIAL AND METHODS: Forty extracted sound primary molars had their crowns prepared in a standardized mach

30. Interproximal space recovery using an orthodontic elastic separator before prosthetic restoration: a case report
A presença dos pontos de contato dentais é essencial para a manutenção da oclusão habitual e da saúde das estruturas periodontais. Ocasionalmente as cáries dentárias podem comprometer o ponto de contato interproximal, induzindo a migração de dentes adjacentes com conseqüente retenção de alimento, inflamação gengival, formação de bolsa period

31. Tratamento de lesões profundas de cárie : um ensaio clínico randomizado comparando tratamento expectante com remoção parcial da dentina
This randomized multicenter clinical trial evaluated the effectiveness of an alternative treatment on deep caries lesion¿s compared to stepwise excavation (SW) after three years follow up. Treatment consisted on partial caries removal (PDR) followed by tooth¿s restoration in one session. Methods: Inclusion criteria were: patients with permanent molars pres

32. Efeito da base de cimento de ionômero de vidro modificado por resina e técnicas de inserção de resina composta na interface dentina/restauração adesiva / Effect of resin-modified-glass-ionomer linning and composite placement on adhesive interface
The aim of this study was to evaluate the effect of resin-modified-glassionomer linning and incremental technique on the bond strength of the composite restoration interface. Methods: Cavities were made (4.5mm X 3mm X 5mm) in 52 extracted human molars, divided into 4 groups: Group 1 (control) no linning + two horizontal increments (C Factor = 5); Group 2: no

33. Análise morfológica e da resistência adesiva dos tecidos dentais duros irradiados com lasers de pulsos ultracurtos / Evaluation of dental hard tissues irradiated with ultra-short pulsed lasers. Influence on surface morphology and microtensile bond strength
The development of restorative dentistry has reached the era of esthetic adhesive restorations and minimally invasive approach, for which innovative techniques and advanced materials are constantly introduced. Conservative techniques aim not only to remove carious dental substrate, but also to prepare cavity surfaces for adhesive restoration. The main object

34. Where and how are Brazilian dental students using Glass lonomer Cement?
Glass Ionomer Cements (GICs) have a wide range of uses in Dentistry, and the manipulation technique used can influence the results obtained. This study aimed at assessing the knowledge held by Dental School students from a city in Southern Brazil regarding the use of GIC, and the clinical technique chosen for its use and its applications. A structured questi

35. Influence of dental metallic artifact from multislice CT in the assessment of simulated mandibular lesions
OBJECTIVE: This study evaluated the influence of metallic dental artifacts on the accuracy of simulated mandibular lesion detection by using multislice technology. MATERIAL AND METHODS: Fifteen macerated mandibles were used. Perforations were done simulating bone lesions and the mandibles were subjected to axial 16 rows multislice CT images using 0.5 mm of s

36. Toxicity of chlorhexidine on odontoblast-like cells
Chlorhexidine gluconate (CHX) is recommended for a number of clinical procedures and it has been pointed out as a potential cavity cleanser to be applied before adhesive restoration of dental cavities. OBJECTIVE: As CHX may diffuse through the dentinal tubules to reach a monolayer of odontoblasts that underlies the dentin substrate, this study evaluated the
