Newly available materials for retrograde obturation should have their sealing properties evaluated. The goal of this study was to evaluate the sealing ability of Endo CPM sealer, an MTA-based endodontic cement. Single-rooted extracted human teeth were endodontically treated. After apical sectioning, retrograde cavities were prepared. Teeth were divided into five experimental groups (n=12), in w...

Two surgical cases are presented in which retrograde instrumentation of the root canal was accomplished with sonic or ultrasonic instruments. The canals were obturated from a retrograde direction with thermoplasticized gutta-percha and root canal sealer. Success of these treatment approaches is attributed to thorough debridement and satisfactory obturation with equipment only recently available...

PURPOSE The aim of this study was to answer the question: For patients requiring apicoectomy (apicectomy/root-end resection) and retrograde (root-end) obturation (filling), which retrograde obturation (root-end filling) material(s) is/are the most effective, as determined by reduction in periapical radiolucency and elimination of signs and symptoms? MATERIALS AND METHODS A MEDLINE and a Cochr...

there is some concern that root resection may alter the seal of the previously set orthograde material. the aim of this study was to evaluate the apical sealing ability of orthograde mineral trioxide aggregate (mta) and calcium enriched mixture (cem) plugs after resection of the roots.the fluid filtration method was carried out on a total of 51 roots in three experimental (n=15) and two control...

INTRODUCTION A mandatory requirement of root canal therapy is that the obturation and restoration of the tooth must seal the root canals both apically and coronally to prevent leakage and percolation of oral fluids and to prevent recontamination of disinfected canals. Apicoectomy (apicectomy/root-end resection) with retrograde obturation is a widely applied procedure in endodontics, when all ef...

This study was carried out to assess the success rate of apicectomy of anterior and premolar teeth. Out of 336 patients, who had undergone apicectomy in a private practice between 1997–2001, only 256 patients (76.2%) completed the two years recall visits; which was the minimum time recommended in this study to judge whether the operation was successful or not. The age range of the patients was ...

introduction: the aim of this in vitro study was to determine the sealing ability of orthograde proroot mineral trioxide aggregate (mta) and calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: fifty four extracted single-rooted human teeth were used. the samples were randomly divided into 3 experimental groups. in group a and b, 4 mm of wmta and cem cemen...
