O tratamento endodôntico é de fundamental importância para abolir a infecção nos dentes com necrose pulpar. O sucesso desse tratamento depende: da eliminação eficiente da infecção no sistema de canais radiculares (SCR) e do correto selamento pela obturação dos canais radiculares. Devido à complexidade anatômica do SCR, certas áreas podem ser inacessíveis ao preparo biomecânico (PBM), portanto, o emprego de uma medicação intracanal potencializa a redução dos microrganismos (MO) e seus produtos tóxicos no SCR. Mesmo com o avanço técnico e científico da Endodontia, há MO que ainda sobrevivem ao PBM, sendo os principais responsáveis pela manutenção infecção endodôntica. Assim, novos tratamentos devem ser pesquisados. Com o advento dos aparelhos de laser e LED, surgiram alternativas de tratamentos na área da saúde, como a terapia fotodinâmica (TFD), que é um conjunto de procedimentos físicos, químicos e biológicos, que ocorrem após a administração de um agente fotossensibilizador (FS) ativado por meio de uma luz visível de comprimento de onda específico (laser ou LED) para destruir a célula-alvo, ou auxiliar no combate das infecções. Na Endodontia, foram demonstrados em estudos in vitro e in vivo que o emprego da TFD atua como um coadjuvante e potencializa a desinfecção do SCR, além de ser de fácil aplicação e não promover resistência microbiana. O objetivo da presente revisão é apresentar o estado atual da terapia fotodinâmica em Endodontia.

Enteric organisms, pseudomonads and other opportunistic microorganisms in the oral microbiota have been linked to serious infections in patients hospitalized in intensive care units (ICU). The present study evaluated the presence of family Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii in the mouth of patients in ICU, correlating it with oral and systemic conditions. Data on health, socioeconomic status, medication use, drug addiction, medical and family histories of patients held for more than 72 hours in the ICU with a diagnosis of severe infection or that developed this condition after entry in said unit were obtained. Fifty patients provided clinical samples of supragingival and subgingival biofilms, saliva and oral mucous membranes were collected, as well as respiratory secretions from patients with pneumonia, blood and urine for sepsis. The presence of target microorganisms was carried out by polymerase chain reaction (PCR) and by culture using selective media. The Chi-square and Mann-Whitney tests were used for statistical analysis, and the significance level was 5%. The intraoral clinical conditions of the patients were poor. The family Enterobacteriaceae was the most prevalent, affecting 39.5% of the supragingival biofilm samples of patients attended in ICU and 18.6% of patients in the control group, besides the rods were the only group found in extraoral samples.

The relationship between the occurrence of enterococci in the oral microbiota and serious infections in patients hospitalized in intensive care units (ICU) has been established. This study evaluated the presence of Enterococcus faecalis and other species of this genus in the mouths of patients on ICU, correlating it with oral and systemic conditions. Data on health and socioeconomic, medication use, medical and family history of patients maintained for 72 hours in the ICU, diagnosed with severe infection or who have developed this condition after the entry to the unit were obtained. Fifty patients provided intraoral and extraoral clinical samples for analysis (above and subgingival biofilm, saliva and buccal mucosa, followed by obtaining samples of respiratory secretions for patients with pneumonia, and blood and urine for sepsis). The presence of target microorganisms was performed by polymerase chain reaction (PCR) and culture using selective media. The chi-square and Mann-Whitney tests were used for statistical analysis, and the significance level was 5%. The intraoral clinical conditions of the patients showed poor. E. faecalis was significantly more frequent microorganism, followed by E. faecium. The use of broadspectrum antimicrobial action was associated with the presence of these opportunistic microorganisms. These bacteria were more frequent in patients with periodontitis or gingivitis. The results showed that enterococci associated with serious infectious processes may originate from resident microbiota of patients and its prevalence is not elevated in healthy individuals.

Devido à constante preocupação do meio ambiente, o uso de fluidos de corte tem se tornado um problema para a indústria mecânica atual por se tratar de substâncias tóxicas. Seu uso e sua dificuldade de descarte devido rígida Legislação Ambiental, faz com que o fluido de corte seja responsável por uma grande parte do custo final do processo, provocando, desse modo, um grande interesse em pesquisas referentes a métodos alternativos de forma e quantidade de fluido de corte utilizado. Ao lado das vantagens tecnológicas associadas com o uso dos fluidos de corte estão os enormes perigos atrelados a estes, e que são nocivos ao meio ambiente e à saúde das pessoas. A contaminação do solo, água e ar podem decorrer de vazamentos e perdas, emissões, água de lavagem e da própria disposição dos fluidos de corte.Os componentes dos fluidos de corte como bactericidas e fungicidas reagem com outros produtos inseridos no processo de corte, tornando os fluidos, materiais que podem vir a causar doenças. Assim, este trabalho tem como objetivo apresentar a utilização do fluido de corte por mínima quantidade de lubrificação como alternativa para se minimizar o impacto ambiental das indústrias mecânicas.

Conjugal problems may damage parents and children relationships favoring the appearance of behavior problems, as well as causing psychological problems. Given the lack of studies which value several interrelated behavioral repertoires, the present paper aims at presenting assessment results employing multiple instruments in regards to the three couples that sought clinical services at a University clinic. Results indicated that participants were presenting communication deficits, problem solving difficulties, and problems in expressing affection confirming literature findings. Problems in other areas were also reported, which influenced the marital relationship. It stands out that the children were presenting indications of behavior problems. The relevance of data collection applying different instruments is discussed, and it is necessary that intervention programs consider individual difficulties, besides setting up singular objectives for each person searching for service.

This study inserts itself in the research line conceptions on the nature of the science (CNC) in the school atmosphere. More specifically, on that teacher of natural sciences who claims not to be interested in philosophy, it is usually noticed a tendency to understand and to teach a vision of a ready/ finished and unalterable science, which directly influences the students conception of science. Discussed here is the application of a didactic rational reconstruction in high school, the results of which are compatible with a more epistemologically acceptable educational concep tion on the nature of science as something provisory, variable and controversial.
