The aim of the present in-vitro study was to evaluate and compare the apical microleakage of Retroplast, Ketac-N100 and heat burnished gutta-percha before and after post space preparation using fluid filtration system. A total of 60 freshly extracted human maxillary anterior teeth were decoronated to obtain a uniform length of 15 mm. each. Mean microleakage of all three materials before and aft...

Objectives: Different chelators may be used during root canal treatment, offering various advantages including lubricant effect inside the canal and smear layer removal. However, chelator residues in narrow root canals can lead to apical microleakage. The aim of this in-vitro study was to compare apical microleakage following the use of three root canal chelators via fluid filtration method in ...

introduction: adequate root canal seal following retreatment is essential for a successful outcome. resilon/epiphany (r/e) obturation system has been introduced as a substitute for conventional gutta-percha/sealer method. this in vitro study compared the amount of apical microleakage of r/e with gutta-percha/ah26 (gp/ah26) sealer as secondary root canal filling following retreatment in human te...

Introduction: Apical seal in blood or dry root canal is a problem in endodontic treatment. Failure of apical seal causes inflammatory reaction and failure root canal treatment. Because of the sealer properties, root canal should be dry for obturation. But hydrophilic sealers can adhere to root canal walls nowadays and this problem is still controversial. This study aimed at determining the apic...

BACKGROUND AND AIMS Microleakage has been identified as a significant problem with composite restorations because of interfacial gap formation which can result in tooth discoloration, recurrent caries, possible pulpal involvement and restoration replacement. Aim of this study is to evaluate the microleakage of self-etch adhesive system at the coronal and apical margins of class V resin composit...

INTRODUCTION Endodontic treatment in pulpless immature teeth is challenging due to the lack of an apical stop. Insertion of an apical plug is an alternative to conventional long-term apexification with calcium hydroxide. The aim of this study was to compare the apical microleakage of mineral trioxide aggregate (MTA) and calcium-enriched mixture (CEM) cement as apical plugs with three different ...

objective: root canal obturation is an important step in endodontic therapy aiming at achieving a complete three-dimensional seal of the canal and preventing microleakage, reentry or growth of microorganisms in the root canal system. several techniques and materials are available for root canal filling. achieving an apical seal is among the most important characteristics of filling materials. t...
