27. AvaliaÃÃo in vitro da infiltraÃÃo apical em canais reobturados com o sistema resilon-epiphany, sob a aÃÃo prÃvia de duas tÃcnicas de desobturaÃÃo / AN IN VITRO EVALUATION OF THE SEALING ABILITY OF THE RESILON/EPIPHANY SYSTEM AFTER RETREATMENT OF CANALS PREVIOUSLY FILLED WITH DIFFERENT MATERIALS
O propÃsito deste estudo in vitro foi comparar a qualidade do selamento apical de canais radiculares reobturados com o sistema Resilon/Epiphany, quando inicialmente obturados com a guta-percha em associaÃÃo a dois cimentos endodÃnticos (Endofill e AH-Plus), bem como com prÃprio sistema Resilon/Epiphany, apÃs duas tÃcnicas de desobturaÃÃo.

28. InfluÃncia do material e tÃcnica de obturaÃÃo endodÃntica na resistÃncia à fratura de raÃzes dentais humanas / Influence of material and endodontic techinique obturation on fracture resistance of human dental roots
A guta-percha associada a um cimento endodÃntico representa o recurso mais usado para a obturaÃÃo dos canais radiculares. Esta associaÃÃo, porÃm, nÃo possui adesividade Ãs paredes de dentina, fato este que pode ensejar falhas na massa obturadora no interior do canal radicular e induzir a fraturas radiculares. O sistema Resilon/Epiphany, como alternat

29. Effect of eugenol-based endodontic sealer on the adhesion of intraradicular posts cemented after different periods
OBJECTIVE: This study evaluated in vitro the influence of an eugenol-based sealer (EndoFill) on the retention of stainless steel prefabricated posts cemented with zinc phosphate and resin-based (Panavia F) cements after different periods of root canal obturation, using the pull-out test. MATERIAL AND METHODS: Sixty upper canines were decoronated and the root

30. Influence of smear layer removal on the obturation of root canal ramifications
OBJECTIVE: This study evaluated whether smear layer removal has any influence on the filling of the root canal system, by examining the obturation of lateral canals, secondary canals and apical deltas. MATERIAL AND METHODS: Eighty maxillary and mandibular canines were randomly divided into two groups, according to their irrigation regimen. Both groups were i

31. 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,

32. : 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

33. Influence of calcium hydroxide dressing on Epiphany TM sealer depth of dentinal tubules and interface dentine-sealer: a confocal study / Influência do hidróxido de cálcio na penetração do cimento Epiphany TM nos túbulos dentinários e na adaptação às paredes do canal radicular: avaliação pela microscopia confocal de varredura a laser
Avaliou-se a influência do curativo intra-canal com pasta de hidróxido de cálcio na penetração do cimento EpiphanyTM no interior dos túbulos dentinários e na adaptação do cimento às paredes dos canais radiculares utilizando-se a microscopia confocal de varredura a laser (MCVL). Foram utilizados 30 incisivos centrais inferiores humanos, extraídos,

34. Evaluation of the apical infiltration after root canal disruption and obturation
The aim of this study was to evaluate two root canal filling techniques used in teeth that had their apical foramen disrupted and compare the apical infiltration with an ideal clinical situation. Twenty-seven freshly extracted single-rooted teeth were selected and radiographed to confirm the existence of a single and straight root canal. The crowns were remo

35. 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

36. Comparison of radiographic measurements obtained with conventional an indirect digital imaging during endontic treatment
The aims of this study were to evaluate the quality of indirect digitized radiographic images taken during endodontic procedures and to compare the measurements recorded with this technique to those obtained from conventional radiographs. Two-hundred conventional periapical radiographs taken at the undergraduate Endodontics Clinic of the Dental School of Bau
