introduction: the purpose of this study was to evaluate the sealing ability of dentin bonding agents in root canals obturated with gutta-percha and mta. methods: forty-five single rooted human premolar teeth were decoronated so that remaining root portions were 12 mm in length. the samples were divided randomly into three experimental (n=13) and two control groups (n=3). all teeth were instrume...
هدف از این پژوهش بررسی خواص ضدباکتریای جدایه های انتروکوکوس از پنیر سنتی کردی با تکیه بر روش های مبتنی بر کشت بوده است. برای این منظور با استفاده از تکنیک های “lawn on the spot” و “well diffusion” از بین 16 انتروکوکوس جدا شده از پنیر کردی، جدایه های دارای خاصیت بازدارندگی غربال شدند، با توجه به آنالیزهای آماری نوع شاخص اثر معنی داری بر قطر هاله بازدارندگی ناشی از کشت جدایه ها نداشت. در حالی که ...
Background and Aims: To ensure root canal treatment success, endodontic microbiota should be efficiently reduced. Several irrigation devices have been recently introduced with the main objective of improving root canal disinfection.The purpose of this study was to evaluate the rinsing effect of RinsEndo system in reduction of enterococcus faecalis in comparison with conventional hand syringe ...
introduction: the aim of this study was to compare the antimicrobial effects of 2.5% sodium hypochlorite (naocl), 2% chlorhexidine gluconate (chx) and biopure mtad (mtad) on enterococcus (e) faecalis -contaminated root canals of human extracted teeth. materials and methods: seventy human intact extracted single-rooted teeth with straight root canal randomly divided into 5 groups: positive contr...
Resistance to linezolid among Enterococcus faecium and Enterococcus faecalis isolates has been reported in patients who receive a prolonged course of the drug. We report two cases of linezolid-resistant Enterococcus faecalis that occurred in patients who previously received linezolid for infections with vancomycin-resistant Enterococcus faecium. Both isolates had the G2576U mutation in the 23S ...
Enterococcus species were considered as non-pathogenic bacteria until recognized as an important cause of bacterial endocarditis in 1899. During the past decade, there has been a worldwide increase in occurrence of enterococcal infections. Though more than 28 enteroccocal species described, Enterococcus faecalis and Enterococcus faecium are isolated most frequently. This might be explained by t...
Background and Aim: Enterococcus species are opportunistic pathogens and their pathogenicity seems to be related to the presence of a number of pathogenicity genes. Since donkey’s milk is a new non-allergenic source of nutrition, this study was performed to assess the antibiogram and detection of pathogenicity genes in some Enterococcus faecalis isolates from donkey’s milk. Materials and Method...
Background: Enterococcus faecalis is a normal flora of the oral cavity, commonly detected in saliva and persistence in endodontic infections. These bacteria have diverse survival and virulence factors. Hemolysin is one of the factor and still had unclear role as a virulence factor of the Enterococcus faecalis to survive in the root canal. Purpose: The purpose of this research was to analyze the...
Abstract Background and Objective: some of predisposing factors for enterococci colonization are hospitalization in ICU, prolonged use of antibiotics and continued bed rest in hospital. In this study antibiotic resistance of enterococcus in hospitalized patients of four hospitals in Tehran were studied. Material and Methods: the Clinical samples were taken from patients admitted to the ICU, fro...
Background: Nosocomial infections can be a major challenge for medical staff and health care providers when it comes to antibiotic-resistant bacteria. Enterococcus faecalis is one of the bacteria that plays an important role in nosocomial infection. Therefore, it is important to study the prevalence and pattern of resistance of this bacterium in medical centers, especially in hospitals. The aim...
