Bacterial Leakage of Mineral Trioxide Aggregates and Portland Cement
INTRODUCTION The purpose of this study was to compare the ability of ProRoot mineral trioxide aggregate (PMTA) and Root mineral trioxide aggregate (RMTA) as root-end filling materials, and Portland cement (PC) to prevent bacterial leakage through filled root end cavities. MATERIALS AND METHODS Fifty-one extracted human single rooted teeth were cleaned and shaped using a step back technique. T...
متن کاملPortland cement with additives in the repair of furcation perforations in dogs.
PURPOSE To evaluate the use of Portland cements with additives as furcation perforation repair materials and assess their biocompatibility. METHODS The four maxillary and mandibular premolars of ten male mongrel dogs (1-1.5 years old, weighing 10-15 kg) received endodontic treatment (n=80 teeth). The furcations were perforated with a round diamond bur (1016 HL). The perforations involved the ...
متن کاملHealing of Root Perforations Treated with Mineral Trioxide Aggregate (mta) and Portland Cement
Fourteen root perforations were performed for microscopic evaluation of the repair of interradicular tissue in dogs' teeth. These perforations were accomplished at low-speed with a STP 58 bur at the cervical third of the mesial root toward the furcation under irrigation with saline solution, followed by immediate sealing with ProRoot MTA, MTA-Angelus and white Portland cement. The dogs were kil...
متن کاملEffect of additives on the compressive strength and setting time of a Portland cement.
Improvements in strength and setting time of Portland cements (PC) are needed to enhance their performance as endodontic and load bearing materials. This study sought to enhance the compressive strength and setting time of a PC by adding one of the following additives: 20% and 30% poly-methylmethacrylate (PMMA), 20% and 30% irregular and spherical amalgam alloys, and 10% CaCl(2). The control co...
