2. 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

3. Marginal microleakage of class V resin-based composite restorations bonded with six one-step self-etch systems
This study compared the microleakage of class V restorations bonded with various one-step self-etching adhesives. Seventy class V resin-based composite restorations were prepared on the buccal and lingual surfaces of 35 premolars, by using: Clearfil S 3 Bond, G-Bond, iBond, One Coat 7.0, OptiBond All-In-One, or Xeno IV. The Adper Single Bond etch-and-rinse

4. Microleakage in combined amalgam/composite resin restorations in MOD cavities
AIM: To compare marginal seal at tooth-material and material-material interfaces in the proximal box in combined amalgam/composite resin restorations. METHODS: Mesio-occlusal-distal (MOD) cavities were prepared in 35 premolars and permanent molars with carbide bur. The distal proximal box was restored with amalgam (Permite, SDI) until reaching the height of

5. An alternative method for thermal cycling test: effect on the marginal microleakage and bond strength of dental polymer bonded to dentin
This study evaluated an alternative method for thermal cycling test on the microleakage and bond strength of the polymer-dentin bond. For the microleakage test the cavities were restored with a TEGDMA+UDMA+bis-EMA composite polymer light cured for 20 s. Samples were immersed in 2% methylene blue solution for 2 h and sectioned. Microleakage scores were submit

6. 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

7. Influence of marginal fit and cement types on microleakage of all-ceramic crown systems
The purpose of this study was to evaluate the effects of both marginal fit and cementing with different luting agents on the microleakage of all-ceramic crown systems. Thirty-six extracted upper central incisors were prepared for full-coverage crowns and were divided into three groups. Group 1: CAD/CAM-fabricated ZrO2, Group 2: Heat-pressed lithium-disilicat

8. Characterization of aqueous silver nitrate solutions for leakage tests
OBJECTIVE: To determine the pH over a period of 168 h and the ionic silver content in various concentrations and post-preparation times of aqueous silver nitrate solutions. Also, the possible effects of these factors on microleakage test in adhesive/resin restorations in primary and permanent teeth were evaluated. MATERIAL AND METHODS: A digital pHmeter was

9. Apical microleakage and SEM analysis of dentin surface after 980 nm diode laser irradiation
Este estudo avaliou o efeito do laser de diodo 980 nm na microinfiltração apical e na morfologia intrarradicular da dentina. Raízes de 110 incisivos inferiores foram utilizadas no estudo: 92 para o teste de microinfiltração e 18 para microscopia eletrônica de varredura (MEV). As raízes foram divididas em 3 grupos de acordo com a solução irrigante (�
