BACKGROUND Current technological advances have allowed application of different study designs and techniques for investigation of dental anatomy. Some clinical studies have provided evidence that Cone Beam computed tomography (CBCT) scanning is an important resource in assessment of root canal systems notably to identify MB2 canals in maxillary molars as CBCT scans allow in vivo dental investig...

OBJECTIVE This study investigated the effect of different ferrule heights on endodontically treated premolars. MATERIAL AND METHODS Fifty sound mandibular first premolars were endodontically treated and then restored with 7-mm fiber post (FRC Postec Plus #1 Ivoclar-Vivadent) luted with self-polymerized resin cement (Multilink, Ivoclar Vivadent) while the coronal section was restored with hybr...

The ideal restoration of endodontically treated teeth (ETT) has been widely and controversially discussed in the literature. Prevention of healthy dental structure is essential to help mechanical stabilization of tooth-restoration integrity, increase the amount of suitable surfaces for adhesion and thus positively affect the long-term success. ETT are affected by a higher risk of biomechanical ...

Introduction: The restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. The aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. Methods: E...

The objective of this retrospective practice-based study was to evaluate the survival molar teeth and endodontic success after complex treatment up 89 months. Endodontically (Endodontic Treatment Classification (ETC) scores II III) treated first second molars between January 2011-October 2017 within a referral setting were included. Open apices, combined surgical treatment, ETC score I, patient...

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...
