Background The treatment of root canal infection consists of eradicating microbes from the root canal and preventing re infection by root filling. Though the existing intra canal medicaments fight against multidrug resistant microbes in root canal, still re-infections occurs. The objective of this study is to synthesize new b-lactam compounds and evaluate their antimicrobial activity to treat r...

introduction : to evaluate the efficacy of niti mechanical rotary instrumentation and hedstrom file for gutta-percha/sealer removal computed tomography (ct) was utilized in vitro . materials and methods: thirty extracted human single rooted teeth, each with a single canal were selected. the samples were decoronated with a double faced diamond disk to have 17-mm root; teeth roots were instrument...

Introduction: Mineral trioxide aggregate (MTA) has a variety of possible uses, including root-end filling material due to its excellent sealing ability in the presence of moisture and a high degree of biocompatibility. Aim: This case report demonstrates the use of MTA as an obturating material to promote periapical healing of root canals with large apical rarefactions. Materials and Methods: An...

This case report presents conservative management of unset mineral trioxide aggregate (MTA) after being placed as a root-end filling material following periapical surgery. Periapical surgery was indicated for a maxillary lateral incisor of a 15-year-old male due to persistent exudate and a large periapical lesion. During surgery Angelus MTA was placed as root-end filling. The next session it wa...

OBJECTIVE To evaluate the discrepancy of root canal filling (RCF) measurements obtained from original root specimens and cone-beam computed tomography (CBCT) images. MATERIAL AND METHODS Seventy-two human maxillary anterior teeth were prepared up to an ISO #50 K-File 1 mm short of the apical foramen. Thus, the teeth were randomly divided into 8 groups, according to the root canal filling mate...

The aim of this study was to evaluate in vitro the cytotoxicity on human periodontal ligament fibroblasts of three root-end filling materials: MTA Angelus®, EndoSequence Root Repair Material Putty® and Super EBA®. A primary culture of human periodontal ligament fibroblasts was previously obtained in order to evaluate the cytotoxicity of the three extracts from the root-end filling materials aft...

BACKGROUND AND AIMS Legume nitrogen is derived from two different sources, symbiotically fixed atmospheric N(2) and soil N. The effect of genetic variability of root and nodule establishment on N acquisition and seed protein yield was investigated under field conditions in pea (Pisum sativum). In addition, these parameters were related to the variability in preference for rhizobial genotypes. ...

GIC, microleakage, Miracle Mix, MTA, root-end filling. Abstract The main objective of a root end filling material is to provide an apical seal that prevents the movement of bacteria and the diffusion of bacterial products from the root canal system into periapical tissues. The aim of this study was to compare the microleakage of three root end filling materials Mineral trioxide aggregate (MTA),...
