Purpose: This in vitro study aimed to evaluate the influence of fatigue loading on fracture resistance endodontically treated molars restored with endocrowns using different machinable blocks. Methods: Endodontically mandibular first were prepared a standardized method. Specimens divided into 4 groups (n = 10).Anatomically shaped manufactured VITA ENAMIC (VE) and KATANA Zirconia (KZ). Layered I...

This is a case report of the presentation and the management of an apicomarginal defect which was associated with a root end fracture in an endodontically treated tooth. In spite of a successful Root Canal Treatment (RCT), if the fractured root end is left intact, considering inadverdent ankylosis or resorption, it may progress to the development of a bony dehiscence.

This article describes a clinical case of mandibular second premolar with three separated canals in apical third of the root that are diagnosed and endodontically treated. Sound knowledge of root canal anatomy and morphology, tactile examination of canal walls, critical interpretation of radiographs and high magnification examination are essential elements of success in complicated root canal t...

Endodontically treated teeth with inadequate tooth structure are highly susceptible to fracture and posts have been commonly used to restore such teeth.Custom cast posts and prefabricated posts have been commonly employed for a long time. It has been slowly replaced by the fibre posts which are more esthetic and also reduced the occurrence of root fracture which was common with the metallic posts.

INTRODUCTION This cross-sectional survey determined the dental prevalence of apical periodontitis (AP) in selected Iranian population, and evaluated the influence of the quality of root canal treatment (RCT) and their coronal restorations (CR) on the periapical status. MATERIALS AND METHODS A total of 1064 panoramic radiographies were evaluated by two observers during 2009. The quality of RCT...

Purpose: The purpose of this in vitro study was to compare the effect of endocrowns and glass fiber post-retained crowns on the fracture resistance of endodontically treated premolars prepared with or without ferrule. Materials and Methods: Twenty sound mandibular premolars were endodontically treated. They were randomly assigned into 4 groups (n=5), in which, teeth were prepared to receive all...

This study evaluated the shear strength resistance of endodontically treated roots that were restored by two different techniques. Twenty-seven recently extracted single-rooted teeth with similar anatomic characteristics were sectioned to obtain the same length for all specimens. Group I (GI) consisted of 14 roots restored with cast post-core (nickel-chromium alloy) and cemented using zinc phos...

Autogenous dentin has been reported to be a suitable grafting material for certain indications. The purpose of this study was assess the feasibility using endodontically treated teeth application. In present retrospective study, one-stage augmentation lateral ridge defects with shell and particulate (tooth technique (TST)) either obtained from (ETT, 17 patients 21 implants) or non-endodonticall...

Introduction. Endodontically treated teeth are usually weaker due to the loss of tooth structure. As most crown is destroyed, common retention for restoration application a fiber-reinforced composite posts in root canal. In endodontically teeth, there two main problems restorative procedure: reduced resistance remaining structure and choosing necessary adequate restoration. The aim this work wa...
