1. Applying liquid chromatography-tandem mass spectrometry to assess endodontic sealer microleakage
The objective of this study was to describe a new method for the quantitative analysis of a microleakage of endodontic filling materials. Forty extracted single-rooted teeth were randomly divided into three experimental groups. After root canal shaping, the experimental groups were filled using the lateral condensation technique with the Epiphany system (

2. Ex vivo microbial leakage after using different final irrigation regimens with chlorhexidine
Objective To assess the influence of final irrigation protocols with chlorhexidine in the coronal leakage of Enterococcus faecalis in filled root canals. Material and Methods Seventy single-root canals from extracted teeth were prepared using ProTaper instruments. The irrigation protocol accomplished an alternating irrigation with 5 mL of 2.5% sodium hypoc

3. Influência do alargamento foraminal na anatomia apical e na qualidade de selamento após obturação / Influence of apical foramen widening on apical foramen morphology and apical sealing
Introduction: The aim of this study was to evaluate the influence of the working length and apical foramen widening on the anatomy of the apical foramen and on the sealing ability after root canal filling. Methods: Fifty-five palatal roots of maxillary molars were selected. The samples were randomly divided into three groups (n=15) according to the different

4. Conventional dual-cure versus self-adhesive resin cements in dentin bond integrity
During post preparation, the root canal is exposed to the oral cavity, and endodontic treatment may fail because of coronal leakage, bacterial infection and sealing inability of the luting cement. OBJECTIVE: this study quantified the interfacial continuity produced with conventional dual-cure and self-adhesive resin cements in the cervical (C), medium (M) an

5. Seal capability of interim post and core crown with temporary cements
The purpose of the present study was to evaluate the in vitro seal capability of interim post and core crown restorations. Eighty teeth were selected and divided into 8 groups. Four experimental groups received interim posts and core crowns. Half of each group was decoronated at the cementum-enamel junction, groups PCCH and PCZO. The other half was sectioned

6. Influência do uso de diferentes substâncias químicas auxiliares endodônticas na microinfiltração coronária em dentes obturados com Guta-Percha / Endofill ou Sistema Resilon / Epiphany SE / Influence of the use of different auxiliary chemical substances on the coronal microleakage in teeth filled with Gutta-Percha / Endofill or Resilon / Epiphany SE
Este estudo teve como objetivo avaliar a influência de diferentes substâncias químicas auxiliares usadas durante o preparo químico-mecânico do canal radicular sobre a qualidade de selamento coronário dos materiais obturadores endodônticos. Oitenta raízes de pré-molares inferiores humanos foram seccionadas, instrumentadas e divididas aleatoriamente e

7. : Evaluation of the sealing provided by resin-based endodontic filling materials and analysis of the expression of metalloproteinases in human and bovine dentin matrix / Avaliação do selamento do conduto radicular por materiais obturadores endodonticos resinosos e analise da expressão de metaloproteinases na matriz dentinaria humana e bovina
Restorative strategies involving dentin bonding have been increasingly applied to endodontics. The first study evaluated the immediate and long-term sealing ability of adhesive versus conventional endodontic filling materials and investigated the influence of a coronal seal on leakage rates. After chemo-mechanical preparation/irrigation, human roots were fil

8. Evaluation of periapical inflammation response from coronal leakage in dog´s teeth obturated using different resin-based sealers and different obturation techniques / Avaliação da resposta inflamatória periapical resultante da infiltração coronária em dentes de cães obturados com diferentes cimentos resinosos e técnicas obturadoras
Considering the need for three-dimensional obturations and adequate marginal sealing of the radicular canal system as being decisive factors for successful endodontic therapy, this study had as its objective the evaluation of periapical inflammatory responses resulting from coronary infiltration in dogs teeth obturated using different resin sealers (AH Plus,

9. Coronal and apical leakage analysis of two different root canal obturation systems
This study compared the coronal and apical leakage of AH Plus with gutta-percha to that of Epiphany with Resilon. Twenty-four single rooted teeth were instrumented and divided into 2 groups according to the solutions for smear layer removal and the obturation materials employed: Group A - 17% EDTA-T and AH Plus with gutta-percha; Group B - primer and Epiphan

10. Avaliação da capacidade de selamento de três materiais obturadores em canais radiculares de pré-molares de cães preparados para pino intra-radicular expostos ao meio bucal
O presente estudo teve como objetivo avaliar in vivo a capacidade de selamento de três materiais obturadores constituídos de cimentos endodônticos resinosos, sendo dois (AH Plus e EndoRez) associados a cones de guta-percha, e um (Real Seal) a cones de Resilon, em pré-molares de cães, expostos ao meio bucal, após o preparo para colocação de pino prot�

11. Microbial leakage and apical inflammatory response in dog's teeth after root canal filling with different sealers, post space preparation and exposure to the oral environment
Coronal leakage is an important factor affecting the outcome of endodontic therapy. This study evaluated the microbial leakage (ML) and the apical inflammatory response (AIR) in dog's teeth after root canal filling with three endodontic sealers, post preparation and exposure to the oral environment, testing the hypothesis that there is a positive correlation

12. In vitro fluid filtration evaluation of intracoronal sealing ability of three materials used as secondary barrier / Avaliação in vitro da capacidade de selamento coronário de três materiais usados como barreira adicional, em dentes tratados endodonticamente, obturados com diferentes cimentos endodônticos, utilizando o método de filtração de fluído
Great part of endodontic treatment fails because of failures in provisory or definitive restoration, permiting a coronal microleakage. For these reasons, in last years, there is a preocupation in sealing intra-coronal cavity after the treatment, to have in view a longer longevity. So many materials are being used for this purpose. Recently it has been develo
