13. Bonding durability of dental sealants to deciduous and permanent teeth
AIM: To evaluate the bonding durability of materials used as sealants on different dentitions. METHODS: Deciduous (D) and permanent (P) molars were divided into four groups (n=5) and sealed with Fluroshield (F) and OptiBond FL (FL). Blocks of composite resin were built, stored in distilled water (24 h/37 °C), sectioned into 0.8 mm2 and tested at tensi

14. Candida albicans biofilms and MMA surface treatment influence the adhesion of soft denture liners to PMMA resin
The effect of Candida albicans biofilms and methyl methacrylate (MMA) pretreatment on the bond strength between soft denture liners and polymethyl methacrylate (PMMA) resin was analyzed. Specimens were prepared and randomly divided with respect to PMMA pretreatment, soft liner type (silicone-based or PMMA-based), and presence or absence of a C. albicans biof

17. COMPARAÇÃO DE DIFERENTES ENSAIOS MECÂNICOS PARA AVALIAR A RESISTÊNCIA ADESIVA A UMA CERÂMICA Y-TZP / COMPARISON OF DIFFERENTS MECHANICAL TESTS TO EVALUATE THE BOND STRENGTH TO A Y-TZP CERAMIC
This study aimed to evaluate the bond strength using different test types for bonding evaluation, between a yttrium tetragonal zirconia polycrystals (Y-TZP) ceramic and composite resin, considering two types of Y-TZP surface treatments. Three hundred and sixty Y-TZP blocks, received one of the two surface treatments (N= 180): UT- control (untreated) and SS-

19. Tensile bond strength of metal posts after the application of Er:YAG laser treatment to the weakened root canal reinforced with composite resin / Avaliação ex vivo da resistência à tração, de pinos metálicos em raízes fragilizadas tratadas com laser Er:YAG e reforçadas com resina composta
O objetivo do estudo foi avaliar ex vivo a influência da aplicação do laser de Er:YAG na parede dentinária de raízes fragilizadas, reforçadas com resina composta. Cinquenta caninos superiores tiveram suas coroas removidas próximo da junção amelo-cementária e incluídas em bloco de resina acrílica. Após tratamento endodôntico foi realizada a frag

20. Effectiveness of immediate bonding of etch-and-rinse adhesives to simplified ethanol-saturated dentin
This study examined the immediate bond strength of etch-and-rinse adhesives to demineralized dentin saturated with either water or absolute ethanol. The research hypothesis was that there would be no difference in bond strength to dentin between water or ethanol wet-bonding techniques. The medium dentin of 20 third molars was exposed (n = 5). The dentin surf

21. Synthesis and characterization of methylcellulose from cellulose extracted from mango seeds for use as a mortar additive
Methylcellulose was produced from the fibers of Mangifera indica L. Ubá mango seeds. MCD and MCI methylcellulose samples were made by heterogeneous methylation, using dimethyl sulfate and iodomethane as alkylating agents, respectively. The materials produced were characterized for their thermal properties (DSC and TGA), crystallinity (XRD) and Degree of Sub

23. Estudo do uso do agregado miÃdo reciclado de concreto na produÃÃo de argamassa para revestimento vertical / Study of the use of recycled aggregate concrete in the production of mortar for coating vertical
The utilization of fine recycled aggregate originated from concrete debris recycling presents economics advantages, once recycled fine aggregate has lower costs than natural fine aggregate. Besides, there is an environmental gain due to the replacement of natural fine aggregate by recycled aggregate resulting in a in a reduction of damage caused by irregular

24. Estudo da distribuição de tensões e da resistência à tração de interfaces adesivas dentina-resina de duas formas de espécimes submetidos a diferentes protocolos de envelhecimento acelerado / Study of stress distribution and tensile bond strength of dentin-resin adhesive interfaces of two types of specimens submitted to different protocols of accelerated aging
The rapid and frequent development of new materials and restorative techniques necessitate rapid assessments to estimate their clinical outcomes. This study sought to evaluate protocols for accelerated aging, in vitro, capable of simulating the performance of adhesive restorations with challenges inherent to the oral environment. The study included 36 molars
