Root filling bond strength using reciprocating file-matched single-cones with different sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of the present study was to evaluate the bond strength (BS) of root canal fillings to root dentin using the reciprocating file-matched single-cone or lateral compaction techniques with resin-based and calcium-silicate-based sealers. Maxillary canine roots were prepared and filled using o...

Drying protocol influence on the bond strength and apical sealing of three different endodontic sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate the influence of drying protocols (DP) on the apical sealing (AS) and on the bond strength (BS) of teeth filled with different sealers. The root canals of one hundred and fifty-six roots of maxillary canines were prepared with Reciproc rotary files (R50). Th...

Cobalt oxide nanoparticles aggravate DNA damage and cell death in eggplant via mitochondrial swelling and NO signaling pathway

Biol. Res; 49 (), 2016
BACKGROUND: Despite manifold benefits of nanoparticles (NPs), less information on the risks of NPs to human health and environment has been studied. Cobalt oxide nanoparticles (Co3O4-NPs) have been reported to cause toxicity in several organisms. In this study, we have investigated the role of Co3O4-NPs ...

Técnica de revascularização para o tratamento de reabsorção inflamatória externa radicular

O protocolo atual para o tratamento das reabsorções inflamatórias externas radiculares utiliza o hidróxido de cálcio como agente de desinfecção, como curativo de demora, em várias trocas sucessivas e por longo período de tempo. Além da necessidade de várias consultas para a substituição do h...

Avaliação da resistência de união de cimentos endodônticos experimentais à base de MTA e butiletilenoglicol dissalicilato

O objetivo deste estudo foi avaliar a resistência de união de dois cimentos endodônticos experimentais à base de MTA e butiletilenoglicol dissalicilato: MTAe e MTAe-HA. Os cimentos endodônticos comerciais MTA Fillapex e AH Plus foram utilizados como materiais de referência para comparação. Vinte ...

Comparative study of physico-chemical properties of MTA-based and portland cements

Acta odontol. latinoam; 23 (3), 2010
The purpose of this investigation was to evaluate the physicochemical properties of gray and white structural and nonstructural Portland cement, gray and white ProRoot MTA and MTA BIO. The water/powder ratio, setting time, solubility and pH (hydrogen-ion potential) changes of the materials were evaluated...

Sealing ability of MTA-Angelus with propyleneglycol in furcal perforations

Acta odontol. latinoam; 23 (2), 2010
This study evaluated the sealing ability of gray MTA-Angelus mixed with propyleneglycol in furcal perforations using a bacterial leakage test. Furcal perforations were created in 30 human mandibular molars using a size 3 round bur. The samples were divided randomly into 2 experimental groups (n=10) accor...

Histological Evaluation of the Bone Repair Using Mineral Trioxide Aggregate Combined to a Material Carrier

Int. j. morphol; 25 (4), 2007
The aim of this study was to present a possible carrier for MTA, monoolein gel, with the objective to maintain this material in the place that was inserted and verify if this procedure is able to optimize its action. The data were evaluated by histomorphometric method and submitted to statistical analysi...
