1. Influence of remaining coronal thickness and height on biomechanical behavior of endodontically treated teeth: survival rates, load to fracture and finite element analysis
Abstract Objective To evaluate the effect of restorative strategy (fiber post vs cast post and core), coronal height (0 mm vs 2 mm) and thickness (higher than 1 mm vs lower than 1 mm) on survival rate, fracture resistance and stress distribution. Material and Methods Seventy-two bovine teeth were cleaned and allocated in six groups (n = 12). Twenty-four te

2. 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,

3. Avaliação da resistência à fratura de raízes portadoras de pinos metálicos fundidos e de fibra de vidro cilíndricos e cônicos / Evaluation of the resistance to fracture of roots with cast metallic posts and cylindrical and conical fiber-glass posts
This study evaluated in vitro the fracture resistance of roots with metallic and glass-fiber intraradicular retainers, varying the geometric configuration and using the compression test. The sample had 50 central superior incisives: 10 received only the coronary preparation (control) and 40 had their crowns sectioned and radicular canals endodontically treat

4. Evaluation of the resistance to fracture of roots with cast metallic posts and fiber-glass posts at different working lengths, using the compression test / Avaliação da resistência à fratura de raízes portadoras de pinos metálicos fundidos e de fibra-de-vidro com diferentes comprimentos, por meio do teste de compressão
In this study, it was evaluated, in vitro, the resistance of fracture roots with glass-fiber and metallic intraradicular retainers with different lengths, using the compression test. Sixty caries-free superior canines had their crowns sectioned and radicular canals endodontically treated. The roots were embedded in acrylic resin, except for the 4 mm of cervi

5. 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

6. Resistência à fratura de raízes fragilizadas restauradas com resina composta e pinos de fibra de vidro submetidas à ciclagem mecânica / Resistance to fracture of weakened roots restored with composite resin and glass fiber post submitted to cyclic loading
The preservation and restoration of severely weakened pulpless teeth is a difficult and unpredictable procedure. This study evaluated the resistance to fracture and fracture patterns of weakened roots after restoration with glass fiber post, filling core of composite resin and total metallic crown submitted to cyclical and compressive load. Thirty upper cani
