This study evaluated the effects of 10% alphatocopherol on the fracture resistance of endodontically treated teeth subjected to tooth bleaching with hydrogen peroxide and immediately restored with composite resin. Fifty bovine incisors were selected, including 10 sound teeth that constituted the control group (G1 (C)). The remaining 40 teeth, which were endodontically treated, were divided into...

BACKGROUND Endodontically treated teeth have significantly different physical and mechanical properties compared to vital teeth and are more prone to fracture. The study aims to compare the fracture resistance of endodontically treated teeth with and without post reinforcement, custom cast post-core and prefabricated post with glass ionomer core and to evaluate the ferrule effect on endodontica...

tooth avulsion is defined as the complete displacement of the tooth out of its alveolar socket. the treatment of choice is immediate replantation or if that is not possible, placement of the tooth in an appropriate storage media. this report presents replantation of an avulsed maxillary central incisor after 12 hours of storage in milk. the tooth was replanted and splinted. one week later, it w...

The outcomes of both dental implants and endodontically treated teeth have been extensively studied. However, there is still a great controversy over when to keep a natural tooth and when to extract it for a dental implant. This article reviews the benefits and disadvantages of both treatment options and discusses success vs. survival outcomes, as well as the impact of technical advances for mo...

BACKGROUND The aim of endodontic and restorative dentistry is the conservation of natural tooth structure. Endodontically treated tooth (ETT) undergoes loss of tooth structure and changes in physical characteristics. Therefore, proper selection of restoration for ETT is mandatory. The clinical approach of restoring ETT needs taking into considerations several issues. However, the best way to re...

BACKGROUND This study investigated the biomechanical interactions in endodontically treated tooth implant-supported prosthesis (TISP) with implant system variations under dynamic cyclic loads monitored using the acoustic emission (AE) technique. METHODS Macrostructure implants using a taper integrated screw-in (TIS; 2-piece implant) and a retaining-screw (RS; 3-piece implant) connected to an ...

Introduction Identifying the canals and negotiating them to be able to instrument and obturate the tooth is necessary to clinical success. But restoration of the endodontically treated tooth is critical to long-term success. It does not matter if we can complete the endodontic portion of treatment if the tooth cannot be restored. With this in mind, we need to look at the restoration phase from ...

known that these teeth are generally weak because of dental structure loss, cavities, filling preparation, and root canal instrumentation. These teeth are thus rendered weak. Moreover, the decrease in the dentin moisture further lowers their strength properties, thus making them more susceptible to fractures. Therefore, it is necessary to take utmost care while selecting the most efficient way ...

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...
