1. How biomechanics can affect the endodontic treated teeth and their restorative procedures?
Abstract: Endodontic treatment is a common dental procedure used for treating teeth which the pulp tissue has become irreversibly inflamed or necrotic as a result of the carious process or dental trauma. This procedure which involves mechanical and chemical preparation of root canal may affect several mechanical and physical properties of the tooth structure

2. Current options concerning the endodontically-treated teeth restoration with the adhesive approach
Abstract: Adhesive procedures have changed the way to restore endodontically treated teeth (ETT). It started with the shift from cast post-and-core to fiber post. The original focus on strength also shifted towards failure modes, revealing that catastrophic failures are still a concern when restoring endodontically-treated teeth even with fiber posts. As an

3. 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

4. Effect of different ferrule designs on the fracture resistance and failure pattern of endodontically treated teeth restored with fiber posts and all-ceramic crowns
OBJECTIVE: This study investigated the effect of different ferrule heights on endodontically treated premolars. MATERIAL AND METHODS: Fifty sound mandibular first premolars were endodontically treated and then restored with 7-mm fiber post (FRC Postec Plus #1 Ivoclar-Vivadent) luted with self-polymerized resin cement (Multilink, Ivoclar Vivadent) while the c

5. Influence of ferrule preparation with or without glass fiber post on fracture resistance of endodontically treated teeth
OBJECTIVE: This study evaluated the effect of ferrule preparation (Fp) on the fracture resistance of endodontically treated teeth, restored with composite resin cores with or without glass fiber posts. MATERIAL AND METHODS: Forty-four bovine teeth were sectioned 19 or 17 mm (2 mm ferrule) from the apex, endodontically treated and assigned to four groups (n =

6. Influence of intraradicular post and crown ferrule on the fracture strength of endodontically treated teeth
O objetivo neste estudo foi avaliar a resistência à fratura de dentes tratados endodonticamente restaurados com diferentes pinos e diferentes alturas de remanescente dentinário da coroa. Sessenta caninos recém-extraídos foram tratados endodonticamente, separados em 6 grupos (n=10) e restaurados com núcleo metálico fundido (CP0 e CP3), pino pré-fabric

7. Efeito da altura do remanescente coronário, do tipo de reconstrução interna e do tipo de coroa restauradora na deformação e resistência à fratura de dentes anteriores tratados endodonticamente
The endodontically treated teeth restoration is important aspect in dental practice and involves many treatment options with varying complexity. The aim of this study was to evaluate the strain, fracture resistance and failure mode of endodontically treated teeth depending of the post and core type, the ferrule presence, restored with metallic or ceramics re

8. Biomechanics analysis of restored teeth with cast intra-radicular retainer, with and without ferrule / Análise biomecânica de dentes restaurados com retentor intra-radicular fundido, com e sem férula
The aim was to evaluate the influence of variations in the radicular ferrule format given by the casing core on stress developed in the root in a three-dimensional model of one upper second premolar submitted to four load conditions: wedge, vestibular lever, proximal lever and torsion. Six models were built according the average dimensions obtained from the

9. Avaliação de diferentes topografias residuais na distribuição de tensões no remanescente dental por meio da análise de elementos finitos / Different residual topographic analysis in the distribution of tensions in the residual teeth by means of the finite element analysis
The presence of dentin projection above the finish line in the preparation of endodonticaly treated tooth to receive post and core is well established in literature, it influences positively in the resistance of the root. However, due to dental destruction, its not always possible to achieve a homogenous projection design, contributing for deficiencies in th

10. Effect of intraradicular post and the presence of ferrule on the resistance of endodontically treated teeth / Efeito do pino intra-radicular e da presença de férula na resistência de dentes tratados endodonticamente
O objetivo deste trabalho foi avaliar a resistência à fratura de dentes tratados endodonticamente restaurados com diferentes pinos intra-radiculares, sem pinos intra-radiculares e diferentes quantidades de remanescente dentário coronal. Para a realização deste trabalho, foram selecionados 60 caninos humanos recentemente extraídos. Todos os dentes foram

11. Reforço intra-radicular de raizes debilitadas
The aim of this study was to evaluate the fracture resistance of seventy inferior bovine incisors, weakened and restored with different intra-root retention systems: cast post and core; cast post and core with composite resin reinforcement; Flexi-Post; Flexi-Post with polyethylene fiber - Ribbond; Luscent Anchors post; and intra-root retention with Ribbond.
