13. Comparison of Fusobacterium nucleatum and Porphyromonas gingivalis Lipopolysaccharides Clinically Isolated from Root Canal Infection in the Induction of Pro-Inflammatory Cytokines Secretion
Resumo O objetivo deste estudo foi comparar a atividade biológica de lipopolissacarídeos (LPS) purificados a partir de linhagens de Fusobacterium nucleatum e Porphyromonas gingivalis, ambas isoladas de infecções endodônticas primárias (IEP) nos níveis de IL-1β e TNF-α produzidos por macrófagos. Adicionalmente, LPS foi purificado de F. nucleatum e P

14. Antimicrobial action of calcium hydroxide-based endodontic sealers after setting, against E. faecalis biofilm
Abstract Enterococcus faecalis are gram positive bacteria that can mostly resist endodontic therapy, inducing persistent infection in the root canal system. Endodontic sealers with antimicrobial activity may help eliminate residual microorganisms that survive endodontic treatment. The present study aimed at comparing the antimicrobial activity of Acroseal, S

15. Saliva, supragingival biofilm and root canals can harbor gene associated with resistance to lactamic agents
This study aimed to determine the presence of Prevotella strains and genes associated with resistance to lactamics in different oral niches from patients with/without primary endodontic infections. Saliva (S) and supragingival biofilm (SB) were collected from three patient groups: Group I – no endodontic infection (n = 15); Group II – acute endodontic in

16. Efetividade de diferentes sistemas de preparo do canal radicular na eliminação de Enterococcus faecalis / Effectiveness of diferente root canal preparation systems against Enterococcus faecalis
The aim of this study was to evaluate the effectiveness of different chemo-mechanical systems for root canal preparation Self-adjusting File (SAF), TiLOS Anatomic Endodontic Technology System (TiLOS), and Mtwo against Enterococcus faecalis in the canal. Forty seven human mandibular bicuspids were contaminated with E. faecalis (ATCC 29212) for 21 days and div

17. Conventional dual-cure versus self-adhesive resin cements in dentin bond integrity
During post preparation, the root canal is exposed to the oral cavity, and endodontic treatment may fail because of coronal leakage, bacterial infection and sealing inability of the luting cement. OBJECTIVE: this study quantified the interfacial continuity produced with conventional dual-cure and self-adhesive resin cements in the cervical (C), medium (M) an

18. Estudo do hidrÃxido de cÃlcio associado ou nÃo à clorexidina como medicaÃÃo intracanal de dentes permanentes necrosados / Study of calcium hydroxide associated or not to chlorhexidine as intracanal medication in necrotic teeth
Aware that the main objective of endodontic treatment is the removal of microorganisms and the prevention of re-infection inside the root canal, and that the infections are polymicrobial and difficult to eliminate, the biomechanical preparation is essential for disinfection, though it is unable to eradicate all microorganisms. The intracanal medication is us

19. Avaliação in vitro do controle microbiano e da neutralização de endotoxinas presentes em canais radiculares por nanopartículas de prata / Effectiveness of silver nanoparticles on microorganisms and endotoxins in root canals
The objective of this study was to evaluate the antimicrobial effect and endotoxin detoxified of solution of silver nanoparticles used as irrigating and dressing in root canals. Forty-eigth single-root human teeth were used. All root canals sized 16 mm and were enlarged to a Kerr file number .30. Root canals were infected for 28 days with E. coli and for 21

20. âO uso da clorexidina intracanal em molares decÃduos com necrose pulpar â estudo clÃnico e microbiolÃgicoâ / Intracanal chlorhexidine in primary molars with pulp necrosis- a clinical and microbiological study
The success of endodontic treatment depends on many factors, and the reduction or elimination of bacterial infection is the most important one. Therefore, the use of substances that act against these microorganisms and their products becomes an important stage in treatment. The aim of this in vivo split-mouth study was to compare the efficacy of a 1% chlorhe

21. Identificação microbiologica em dentes com necrose pulpar e abscessos periapicais e a suscetibilidade antimicrobiana de algumas bacterias anaerobias isoladas / Microbial identification in teeth with pulpar necrosis and periapical abscess and the antimicrobial susceptibility of some anaerobic bacteria
The aim of the present study was to analyze the endodontic microbiota of teeth with pulp necrosis and spontaneous pain; detect the presence of enterococci, fungi and enteric bacteria in saliva and root canals; and, to determine, in vitro the antimicrobial sensitivity of anaerobic isolates by E-test and _-lactamasis production. Thirty samples were collected f

22. Identification of microbiological characteristics of root canal of young permanent teeth patients with primary infection / Identificação das características microbiológicas de canais radiculares de dentes permanentes jovens portadores de infecção primária
Em condições de normalidade o cemento e o esmalte atuam como barreira protetora da dentina e do tecido pulpar. Entretanto fatores etiológicos mecânicos, químicos e microbianos podem determinar a perda dessa proteção, conseqüentemente expondo a dentina e, eventualmente, o tecido pulpar ao ambiente bucal, viabilizando sua contaminação. O complexo den

23. In vitro antimicrobial activity of bacteriophages in root canals infected with clinical isolates of Enterococcus faecalis / Estudo in vitro da ação antimicrobiana de bacteriófagos em canais radiculares infectados por isolados clínicos de Enterococcus faecalis
Many studies have investigated different intracanal medications to control infection processes, especially in cases of microbial resistance to disinfection procedures. The purpose of this study was to evaluate the in vitro antimicrobial effect of specific bacteriophages on five isolates of Enterococcus faecalis, as well as the activity of a lysate cocktail i
