direct restoration of severely damaged endodontically treated teeth (ett) using available and conventional and current matrix systems is sometimes impractical and in some clinical cases is impossible. the aim of this paper is to introduce and describe a new matrix system based on rigid tray technique (rtt) for dealing with such difficult clinical cases.

AIMS AND OBJECTIVES The fiber post type used in restoring endodontically treated teeth may affect the dental expert decision in the case of dental malpractice. The aim of this study was to evaluate the low-cost commercial fiber post in comparison with a higher cost or well-known documented fiber post system. MATERIALS AND METHODS A total of 20 premolars were selected for the study; following ...

The extraction of grossly decayed teeth with least remaining tooth structure has now become the history. With advances in the field of dentistry, teeth formerly considered for extraction are now being saved. However, it is clear that significant reconstruction is often required, and evident that a wide variety of ways exist to achieve this. The longevity of endodontically involved teeth has bee...

background and aims. the aim was to evaluate the effect of three methods of fiber insertion on fracture resistance of root-filled maxillary premolars in vitro. materials and methods. sixty extracted human maxillary premolars received endodontic treatment followed by preparation of mesioocclusodistal (mod) cavities, with gingival cavosurface margin 1.5 mm coronal to the cementoenamel junction (c...

The aim of the present study was to investigate the success and survival of restored endodontically treated teeth (ETT) in a general practice environment related to periodontal parameters. Data from 360 restored ETT treated between 2000 and 2011 were collected. Dates of interventions like restorations, repairs, replacements and extractions were recorded. Additionally, general information about ...

introduction: the aim of the present study was to evaluate the effect of three types of luting cements used for post cementation on the fracture resistance of endodontically treated maxillary premolars, restored with resin composite. materials and methods: one hundred intact single-rooted human maxillary premolars were randomly divided into 5 groups of 20 each. in groups 2-5, post spaces were p...

The aims of this systematic review were to investigate the success rates of prosthetic restorations on endodontically treated teeth and their manner of failure. PubMed and hand literature searches were conducted on studies published until June 2012. Only clinical studies on human subjects referring to the success rates of prosthetic restorations on endodontically treated teeth with a follow-up ...

The ideal restoration of endodontically treated teeth (ETT) has been widely and controversially discussed in the literature. Prevention of healthy dental structure is essential to help mechanical stabilization of tooth-restoration integrity, increase the amount of suitable surfaces for adhesion and thus positively affect the long-term success. ETT are affected by a higher risk of biomechanical ...

introduction: the restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. the aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. methods: e...
