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.

The aim of this study was to evaluate the effects of two endocrown designs and computer aided design/manufacturing (CAD/CAM) materials on stress distribution and failure probability of restorations applied to severely damaged endodontically treated maxillary first premolar tooth (MFP). Two types of designs without and with 3 mm intraradicular extensions, endocrown (E) and modified endocrown (ME...

The aim of this study was to evaluate the influence of different restorative procedures on the fracture resistance of endodontically treated teeth submitted to intracoronal bleaching. Fifty upper central incisors were distributed into 5 groups: GI - healthy teeth; GII - endodontically treated teeth sealed with Coltosol; GIII - endodontically treated teeth bleached and sealed with Coltosol; GIV ...

Introduction: Mandibular premolars are considered an enigma in dentistry because of their variability anatomical and morphological features making it difficult to treat endodontically. This study was conducted determine the root canal morphology mandibular Nepalese population by using cone beam computed tomography imaging. Methods: One hundred thirty-four images were collected convenience sampl...

A tooth that has been properly treated endodontically should have a good prognosis. It can resume full function and if necessary serve satisfactory as an abutment for fixed removable partial denture. However special techniques are needed to restore such tooth. Traditionally, pulpless received dowel or post “reinforce” it crown “protect” it. Until the introduction of ZnPO4 cement in last century...

Pulpal pain does not refer to an endodontically treated tooth. Nevertheless, such a potential may exist based on a learned phenomenon due to previous treatment experiences but is rarely reported. Further, it is seldom reported to occur with atypical features. This case report is on a patient who was presented with pain in endodontically treated lower first molar (36) and recommended to undergo ...

T echniques to reinforce endodontically treated teeth have been available for more than 100 years. However, few dentists have questioned the rationale that dictates automatic dowel reinforcement and coronal coverage of pulpless teeth. The difficulties of in vivo studies have motivated investigators to increase the number of in vitro studies of endodontically treated teeth. Although findings fro...
