Aim: The aim of the study was to compare the fracture resistance of endodontically treated teeth obturated with gutta percha using four different root canal sealers (MTA Fillapex, AH plus, Real Seal SE and Tubli Seal). Materials and methods: Sixty freshly extracted single rooted human mandibular premolar teeth were used. After standardizing the root length to 14 mm, the teeth were chemo mechani...

introduction: the resistance to fracture of endodontically treated teeth restored with esthetic post systems has not been extensively researched. this in vitro study compared the fracture patterns of endodontically treated teeth with esthetic post systems with different analysis methods. materials and methods: a total of 26 recently extracted human maxillary central incisors were decoronated an...

This paper aims at evaluating the mechanical performance of endodontically treated teeth. A threedimensional "nite element analysis of teeth is presented. The stress distribution in the teeth restored with a few variants of posts is compared. An improved design of the post is presented. A study on alternative materials for posts has been reported. Conclusions on the ideal shapes and materials o...

It has been the purpose of this article to provide a rationale for the restoration of endodontically treated teeth. Treatment recommendations have been made in the areas of post design, placement technique, cements, core materials, and definitive restorations, based on a review of the clinical and laboratory data.

The clinical success of a restorative procedure of endodontically treated teeth depends on the cementation used to create a link between the restoration and the tooth. The retention of a post is a major factor influencing the survival of the restoration. Most clinical failures involving endodontically treated teeth reconstructed with posts are due to cementation failure of posts, whereas root f...

Procedure Following nonsurgical root canal treatment, a post space is created in the root canal by careful removal of the coronal canal obturating material. A sufficient amount of material must be retained in the apical portion of the canal to maintain an adequate apical seal. A custom or proprietary post is fitted and cemented into the root canal for core retention. The post should be passivel...
