1. Bond strength values of fiberglass post to flared root canals reinforced with different materials
Abstract The aim of this study was to compare in vitro the bond strength (BS) between fiberglass posts and flared root canals reinforced with different materials. The roots of 48 premolars were endodontically treated. After one week, the root canals were prepared to simulate an oversized root canal, except for the positive control group (PCG), which was ceme

2. Clinical performance and failure modes of pulpless teeth restored with posts: a systematic review
Abstract The aim of this systematic review was to compare the clinical performance and failure modes of teeth restored with intra-radicular retainers. A search was performed on PubMed/Medline, Central and ClinicalTrials databases for randomized clinical trials comparing clinical behavior and failures of at least two types of retainers. From 341 detected pape

3. The Influence of a Translucent Fiberglass Post on the Polymerization of Dual Cure Resin Cement Analyzed by Electron Paramagnetic Resonance
AbstractElectron Paramagnetic Resonance (EPR) was used as an alternative method to study the conversion degree of dual cure resin cement and verify the influence of prefabricated translucent fiberglass post on the dual cure resin cement polymerization at different restoration points. The post cementation of White Post DC (FGM, Joinville, SC, Brasil) was simu

4. A numerical study on seismic response of self-centring precast segmental columns at different post-tensioning forces
Precast bridge columns have shown increasing demand over the past few years due to the advantages of such columns when compared against conventional bridge columns, particularly due to the fact that precast bridge columns can be constructed off site and erected in a short period of time. The present study analytically investigates the behaviour of self-centr

5. Fracture resistance of endodontically treated teeth restored with different intraradicular posts with different lengths
AIM: This study compared the resistance to fracture of endodontically treated teeth restored with different intraradicular posts with different lengths and full coverage metallic crowns. METHODS: Sixty extracted human canine teeth were randomly divided into 6 groups. Groups CP5, CP75 and CP10 were restored using custom cast post and core (CP) and groups PF5,

6. Finite element analysis and fracture resistance testing of a new intraradicular post
OBJECTIVES: The objective of the present study was to evaluate a prefabricated intraradicular threaded pure titanium post, designed and developed at the São José dos Campos School of Dentistry - UNESP, Brazil. This new post was designed to minimize stresses observed with prefabricated post systems and to improve cost-benefits. MATERIAL AND METHODS: Fractur

7. Estudo histológico dos tecidos conjuntivo e osteóide em enxertos ósseos com polímero de mamona : estudo experimental em ratos / Histological study of connective and osteoid tissue in bone grafts with castor oil polymer : experimental study in rats
The reconstruction of great bone loss defects represents a challenge for reconstructive surgery. To reconstruct these defects it is necessary to create conditions to stimulate new bone formation, in order to block the connective healing tissue growth towards the bony defect, which blocks the osteogenesis. The autogenous grafts are inconvenient, because they

8. Effect of cyclic load on vertical misfit of prefabricated and cast implant single abutment
OBJECTIVES: The purpose of this in vitro study was to evaluate misfit alterations at the implant/abutment interface of external and internal connection implant systems when subjected to cyclic loading. MATERIAL AND METHODS: Standard metal crowns were fabricated for 5 groups (n=10) of implant/abutment assemblies: Group 1, external hexagon implant and UCLA cas

9. 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

10. Virtual analysis of stresses in human teeth restored with esthetic posts
The use of intra-radicular posts for rebuilding of damaged teeth is a normal practice in contemporary dentistry. However, dental roots restored with posts are subjected to the risk of failure under occlusal loads, particularly in cases of small dentin thickness. This study adopted the finite element analysis to compare the elastic stress distribution in simu

11. Comparison of the fracture resistance of endodontically treated teeth restored with prefabricated posts and composite resin cores with different post lenghts
OBJECTIVE: This study evaluated the fracture strengths of endodontically treated teeth restored with prefabricated posts with different post lengths. MATERIAL AND METHODS: Thirty freshly extracted canines were endodontically treated. They were randomly divided into groups of 10 teeth and prepared according to 3 experimental protocols, as follows; Group 1/3 P

12. Influência da extensão e tipo de retentor intra-radicular na deformacão e resistência à fratura de dentes tratados endodonticamente
Studies concerning the effects of different post systems insertion depth on the strain and fracture resistance of endodontically treated teeth remain controversial. The purpose of this study was to investigate in vitro the effects of different post systems and depth of post insertion on the strain and fracture resistance of endodontically treated bovine inci
