25. Avaliação em estudos longitudinais da eficácia do Hipoclorito de sódio e da Clorexidina sobre o Enterococcus faecalis presente em infecções endodônticas - revisão sistemática
The efficacy of the sodium hypochlorite and chlorhexidine over the Enterococcus faecalis present in endodontic infections was evaluated in longitudinal studies through a systematic review. Bibliographic catalogue sources, electronically identified as MEDLINE (http://www.ncbi.nlm.nih.gov/PubMed), from 1966 until January 1st, and Cochrane Library on the same p

27. Estudos longitudinais da influência do veículo na eficácia da pasta de hidróxido de cálcio em infecções endodônticas - revisão sistemática
Longitudinal studies about the influence of the vehicle on the efficacy of calcium hydroxide pastes in endodontic infections were studied through a systematic review. Bibliographic tabulation sources identified electronically by MEDLINE, since 1966 until January 2nd of 2007 and Cochrane Library, on the same period, were used. As searching strategy the follow

29. Avaliação in vitro da viabilidade de Enterococcus faecalis e Candida albicans nos túbulos dentinários após a aplicação de hidróxido de cálcio e clorexidina gel 2% / In vitro evauluation of the viability of Enterococcus faecalis and Candida albicans in dentinal tubules after placement of calcium hydroxide and chlorhexidine gel 2%
Uma infecção pulpar pode resultar na colonização microbiana de todo sistema de canais radiculares incluindo os túbulos dentinários. Estes microorganismos e seus produtos tóxicos são responsáveis pelo desenvolvimento e persistência da periodontite apical de origem endodôntica. O presente estudo objetivou avaliar a viabilidade de E. faecalis e C. al

30. EFETIVIDADE DO GLUCONATO DE CLOREXIDINA A 1% ASSOCIADO À PASTA DE HIDRÓXIDO DE CÁLCIO (CALEN), COMO MEDICAÇÃO INTRACANAL, NO COMBATE AO Enterococcus faecalis
This study investigated the occurrence of Enterococcus faecalis in clinical specimens obtained from 25 cases in which endodontic treatment failed and 10 cases of primary endodontic infection, both of which are associated with asymptomatic apical periodontitis. As well, in cases in which it was possible to recover this bacterium, the antibacterial actions of

31. Estudo in vitro da atividade antimicrobiana imediata e mediata da clorexidina gel 2% usada como irrigante endodontico contra Enterococcus faecalis
The initiation and perpetuation of pulpal and periapical disease occur due to the presence of bacteria and their degradatory by products in the root canal. The host defense cells are unable to reach bacteria harbored in the root canal system thus, the root canal therapy must be performed combining mechanical procedures and chemical substances. For that reaso

32. Atividade antibacteriana in vitro da clorexidina gel, hidroxido de calcio e associação de ambos utilizados como medicação intracanal em dentina bovina contaminada com Enterococcus faecalis
Recent improvements in endodontic microbiology haves howedt he close relationship between micoorganism and failure of endodontic therapy.The control of endodontic infection is attempted by the observation of the aseptic techniques through out the endodontic therapy, by cleaning and shaping the root canal,by intracanal medication by hermetic filling of the oo

33. Bacteroides buccae and related taxa in necrotic root canal infections.
Fifty-seven adults with apical periodontitis were examined for the presence of nonpigmented Bacteroides species in 62 infected root canals. Nonpigmented Bacteroides species were found in 35 canals. In four cases two nonpigmented Bacteroides species and in one case three nonpigmented Bacteroides species were found. Species belonging to the B. fragilis group w

34. Increased susceptibility of RAG-2 SCID mice to dissemination of endodontic infections.
Specific immunity has been implicated in the pathogenesis of periapical lesions, although the extent to which these mechanisms are actually involved in either protection or destruction of the pulp-periapex complex is yet to be established. To investigate this question we compared periapical-lesion pathogenesis in RAG-2 severe combined immunodeficient (SCID)

35. B-Cell Deficiency Predisposes Mice to Disseminating Anaerobic Infections: Protection by Passive Antibody Transfer
We have previously demonstrated that a high proportion of RAG-2 SCID knockout mice, which lack T and B cells, develop orofacial abscesses and disseminated infections following pulpal infection, whereas immunocompetent control mice do not. In the present study, we sought to identify the components of the adaptive immune response which contribute to protection
