Materials and Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and randomly divided into 3 experimental groups (n=10) and two negative and positive control groups (n=3). Lateral compaction technique was performed using AH26 sealer (group 1 or control), and MTA Fillapex (group 2). The canals in group 3 were filled using vertical compaction of MTA alone. Sea...

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...

INTRODUCTION The purpose of this in vitro study was to assess the apical microleakage of AH26 sealer when three different root canal irrigant regimens were used. MATERIALS AND METHODS Eighty single-rooted human teeth were randomly divided into three experimental (n=20) and two control groups (n=10). NaOCl was used as irrigant during instrumentation, and apical patency was ensured in all teeth...

introduction: the purpose of this in-vitro study was to investigate the influence of the remaining calcium hydroxide (ch) as an intracanal dressing on the apical sealing ability of three endodontic sealers. materials and methods: sixty-six single and straight canals of recently extracted human permanent maxillary central incisors were used. all canals were prepared and sixty of them were random...

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...
