13. Delayed tooth replantation: MTA as root canal filling
MTA has been investigated as a root-end filling material. Its mechanism of action has some similarities to that of Ca(OH)2. The purpose of this study was to evaluate the repair process taking place in the delayed replantation of monkey teeth using calcium hydroxide and MTA as root canal filling materials. Five monkeys had their lateral incisors extracted and

14. Apical adaptation, sealing ability and push-out bond strength of five root-end filling materials
This study compared the fluid filtration, adaptation to the root canal walls, and the push-out bond strength of two resin-based sealers and three calcium silicate-based retrograde filling materials. Fifty maxillary canines were shaped using manual instruments and the apical portion was sectioned. Retrograde cavities of 3-mm depth were prepared. The specimens

15. 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

16. Bond strength to root dentin and fluid filtration test of AH Plus/gutta-percha, EndoREZ and RealSeal systems
OBJECTIVES: To investigate the bond strength and seal ability produced by AH Plus/gutta-percha, EndoREZ and RealSeal systems to root canal dentin. MATERIAL AND METHODS: Sixty extracted single-root human teeth, instrumented manually to size 40, were divided into three groups (n=20) according to the sealer used; G1: AH Plus, G2: EndoREZ, and G3: RealSeal

17. Influência de materiais obturadores e agentes de limpeza na resistência da união e interface adesiva de pinos de fibra de vidro à dentina intrarradicular / Influence of filling materials and cleaning agents on bond strength and adhesion interface of glass fiber post to radicular dentin
The aim of this in vitro study was to evaluate the post-cement-dentin adhesive interface quality and the effect of different filling materials and cleaning agents on the bond strength of glass fiber posts to primary root dentin. This study included 156 roots of bovine primary teeth which were endodontically treated and assigned to four groups (39 teeth each

18. Qualitative SEM/EDS analysis of microleakage and apical gap formation of adhesive root-filling materials
OBJECTIVE: The aim of this study was to compare the correspondence between gap formation and apical microleakage in root canals filled with epoxy resin-based (AH Plus) combined or not with resinous primer or with a dimethacrylate-based root canal sealer (Epiphany). MATERIAL AND METHODS: Thirty-nine lower single-rooted human premolars were filled by the later

19. Effect of root canal filling materials on dimensions of cone-beam computed tomography images
OBJECTIVE:To evaluate the discrepancy of root canal filling (RCF) measurements obtained from original root specimens and cone-beam computed tomography (CBCT) images. MATERIAL AND METHODS: Seventy-two human maxillary anterior teeth were prepared up to an ISO #50 K-File 1 mm short of the apical foramen. Thus, the teeth were randomly divided into 8 groups, acco

20. Avaliação da permeabilidade dentária de dentes submetidos à reintervenção endodôntica quando obturados com diferentes cimentos / Evaluation of the permeability of dental teeth underwent reintervention when filled with different endodontic cements
The purpose of this study was to evaluate ex vivo the permeability of root canal dentin walls after the removal of three different combinations of filling materials. To this end, 36 extracted human single-rooted premolars, with similar length and anatomy, had surgery access to the pulp chamber, root canal preparation was performed to F4 ProTaper instruments

21. Subcutaneous connective tissue response to primary root canal filling materials
Neste estudo avaliou-se a resposta do tecido conjuntivo subcutâneo de camundongos BALB/c a materiais obturadores de canal radicular de dentes decíduos: óxido de zinco/eugenol (OZE), pasta Calen® espessada com óxido de zinco (Calen/OZ) e cimento Sealapex®. Os camundongos (n=102) receberam implantes de tubos de polietileno??? e foram divididos em grupos:

22. Avaliação clínica do uso de pinos de fibra de carbono na restauração de dentes tratados endodonticamente : um estudo retrospectivo
Os estudos clínicos de dentes desvitalizados e restaurados com pinos mostram resultados semelhantes no que diz respeito ao percentual de falhas ou insucessos, apesar de tantas variações técnicas, metodológicas e operatórias entre eles. Os insucessos são maiores quando se tratam de elementos dentais coronariamente destruídos ou comprometidos periapica

24. Sealing ability, marginal adaptation and their correlation using three root-end filling materials as apical plugs
OBJECTIVE: This study used dye leakage assay and scanning electron microscopy to evaluate, respectively, the sealing ability and marginal adaptation of three root-end filling materials used as apical plugs, as well as the possible correlation between these properties. MATERIAL AND METHODS: Ninety-eight single-rooted human teeth were prepared to simulate an o
