1. A microleakage study of gutta-percha/AH Plus and Resilon/Real self-etch systems after different irrigation protocols
The development and maintenance of the sealing of the root canal system is the key to the success of root canal treatment. The resin-based adhesive material has the potential to reduce the microleakage of the root canal because of its adhesive properties and penetration into dentinal walls. Moreover, the irrigation protocols may have an influence on the adhe

2. Bacterial microleakage at the implant-abutment interface in Morse taper implants
AIM: To evaluate the microleakage at the implant-abutment (I-A) interface of Morse tapered implants inoculated with different volumes of bacterial suspension. METHODS: Morse tapered I-A sets were selected and divided in two groups depending on the type of abutment: passing screw (PS) and solid (S), and then subdivided into four subgroups (n=6) accordin

3. Comparison of three obturation techniques with regard to bacterial leakage
AIM: To compare bacterial leakage in root canals obturated with the modified single-cone, lateral condensation, and continuous wave of condensation techniques. METHODS: Distobuccal root canals of maxillary molars were shaped up to ProTaper F2 and obturated with modified singlecone, lateral condensation or continuous wave of condensation technique. Two-chambe

4. Micro-leakage at the implant-abutment interface with different tightening torques in vitro
OBJECTIVES: This study evaluated the microleakage at the implant/abutment interface of external hexagon (eH) implants and abutments with different amounts of bacteria and tightening torques. MATERIAL AND METHODS: A bacterial suspension was prepared to inoculate the implants. The first phase of this study used nine EH implants and abutments that were divided

5. 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

6. Evaluation in vitro of bacterial microleakage in external hexagonal, internal hexagonal and morse-taper dental implants / Avaliação in vitro da microinfiltração bacteriana em implantes do tipo hexágono externo, hexágono interno e cone morse
Três dos principais tipos de implantes disponíveis no mercado são: o hexágono externo, o hexágono interno e o cone morse. Um microespaço, presente entre o implante e o intermediário protético, permite a penetração bacteriana e colonização do interior do implante. Esse microespaço, juntamente com a colonização bacteriana, tem sido associado com

7. Avaliação da microinfiltração bacteriológica na interface pilar/implante em Implantes Hexágono Externo com diferentes torques
O objetivo deste estudo foi avaliar a microinfiltração da interface pilar/implante de implantes hexágono externo (HE) com diferentes torques. Para isso, foram utilizados nove implantes HE torque externo, pilar cônico e seu respectivo parafuso, selecionados aleatoriamente e divididos em três grupos. Utilizados em duas fases do experimento. Uma suspençã

8. High power lasers Influence in bacterial and fungical microleakage in MTA retrofills / Influência da irradiação com lasers de alta potência na microinfiltração bacteriana e fúngica em dentes humanos retrobturados com MTA
Este estudo experimental avaliou, in vitro, a microinfiltração de E. faecalis e C. albicans em raízes cujas superfícies apicais ressectadas e retropreparadas para obturação retrógrada sofreram irradiação dos lasers Nd:YAG, Diodo 810 nm e Er,Cr:YSGG, e posteriormente retrobturadas com MTA. Setenta raízes foram instrumentadas, obturadas endodonticame

9. Avaliação da infiltração microbiana na interface implante-abutment em conexões tipo hexágono interno e cone-morse de implantes osseointegráveis / Evaluation of bacterial leakage at implant abutment interfaces of implants wiht internal hexagonal
The scientific literature has reported that dental implants can be affected by the oral microorganisms through the formation of a bacterial biofilm. The region most affected is the connection between the implant platform and the prosthetic abutment, particularly in implants with an external connection. Therefore, the region of the implant/abutment connection

10. A comparative study of sealing ability of white and gray MTA Angelus and Sealapex added of zinc oxide as root-end filling materials using a bacterial microleakage model. / Avaliação comparativa in vitro da capacidade seladora à infiltração bacteriana dos cimentos MTA branco, cinza e Sealapex consistente em obturações retrógradas
The cements gray MTA Angelus, white MTA Angelus and Sealapex added of zinc oxide (consistent Sealapex) were evaluated accordind to their sealer abilility to the bacterial leakage. Eighty single-rooted extracted human teeth were used, all of them had their crown removed. The roots were divided aleatory in three experimental groups of 20 specimen, one for each
