OBJECTIVE The aim of this study was to compare the apical seal of curved canals obturated with Resilon/Epiphany with gutta-percha/AH Plus. MATERIALS AND METHODS Thirty-four extracted human mandibular molars with 25-40 degree canal curvature of the mesial root were selected for this study. After preparation, the mesiobuccal canals were obturated with gutta-percha and AH- Plus sealer (group G) ...

The oot fillings were removed using chloroform and two ifferent rotary systems (K3 and Liberator files). The mount of residual filling material on the canal walls as imaged and measured using image analyzer...

BACKGROUND AND OBJECTIVE To date, many different materials have been proposed for root canal fillings, but gutta-percha (used with various types of sealers) has remained the material of choice for over a century. A new root canal obturation system, the Epiphany endodontic obturation system, has been developed to replace gutta-percha and traditional sealers for root canal obturation. The purpose...

The season of the Nobel awards and the ensuing ceremonials is upon us. As the current laureates prepare to graciously stand in line before the crowned heads of Sweden and Norway, it’s an appropriate moment to reflect on what the prize has come to mean, and whether it still serves a useful purpose in today’s world. Although the Nobel Prizes are held in high esteem by the general public the world...

INTRODUCTION The purpose of this study was to evaluate the efficacy of three methods in removal of Resilon/new Epiphany self-etch (SE) soft resin endodontic obturation system. MATERIALS AND METHODS Thirty extracted single rooted human teeth were prepared for endodontic treatment and obturated with Resilon/Epiphany SE. The roots were randomly divided into three groups; group 1 roots were retre...

The energy-efficient Adapteva Epiphany architecture exhibits massive many-core scalability in a physically compact 2D array of RISC cores with a fast network-on-chip (NoC). With fully divergent cores capable of MIMD execution, the physical topology and memory-mapped capabilities of the core and network translate well to partitioned global address space (PGAS) parallel programming models. Follow...

Derek Duggan In vivo microleakage evaluation of two root-filling materials in teeth without a coronal seal (Under the direction of Dr. Martin Trope) Two carrier-based materials were compared to assess their resistance to coronal microleakage in a dog model when no coronal seal was present. Histologic evidence of inflammation and infection were the outcome parameters used. Experimental teeth wer...
