Statement of problem: A dowel is essential to retain the core in case of severe tooth destruction. However, the placement of a dowel and core may actually weaken teeth and affect their failure pattern depending on their material properties and stress transfer. Purpose: The present study compared the fracture resistance and failure pattern of endodontically treated premolars with different amoun...

The aim of this in vitro study was performed to evaluate the effect of dentin bonding agents and glass ionomer cement beneath composite restorations and its resistance to fracture of endodontically treated teeth. Fifty sound extracted maxillary teeth were selected; ten of them for controls and the remainder were modified with root canal treatment and a mesial occlusal distal (MOD) cavity prepar...

The prosthetic treatment of seriously damaged, endodonticallytreated teeth often require an endodontic post as an additional retention element for core build-up prior to crown restoration. In addition to metal-based posts and zirconia-based ceramic posts, fiber-reinforced composite posts have recently become a center of interest for dentists and science. In the past it was commonly accepted tha...

One of the most important consideration for patients in dental treatment is esthetics. It presents a great challenge when teeth (particularly anterior teeth) have to be immediately replaced following removal structure. Immediate denture answer restore esthetics and functional (mastication, speech deglutition) purpose. A 48-year-old male patient came Department Prosthodontic Clinic, Universitas ...

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...

For this survey, 92 vertically fractured endodontically treated teeth were evaluated clinically and radiographically before and after extraction. The maxillary second premolars (27.2%) and mesial roots of the mandibular molars (24%) were the most fractured teeth. In 67.4% of the teeth, a solitary buccal pocket was present; in 34.8%, a fistula frequently appeared closer to the gingival margin th...

STATEMENT OF PROBLEM Studies concerning the effects of post-core design and ferrule on the fracture resistance of endodontically treated teeth remain controversial. PURPOSE The purpose of this study was to investigate in vitro the effects of post-core design and ferrule on the fracture resistance of root canal treated human maxillary central incisors restored with metal ceramic crowns.
