ABSTRACT
The aim of this study was to evaluate the effects of different coffee solutions on Streptococcus mutans adherence to human dental enamel and dentine. Seventy-five specimens of human enamel and 75 of dentine were included in the study. Coffee solutions were prepared with two different trade marks of coffee (Mellitari and Pilãori) and two methods of preparation. The specimens were divided into ten experimental groups (n=15) according to the coffee solution tested. Each specimen was transferred to cell culture plates containing offee solution and culture medium and 0.1 ml of Streptococcus mutans standardized suspension was inoculated into each well. After the period of incubation, the number of bacterial cells adhered to each specimen was obtained by plating method. Results were analyzed by ANOVA and TukeyÆs test (5%). Results showed that Streptococcus mutans adherence was statistically lower in the presence of the solution obtained by boiling method and the trade mark PilãoÔ (p=0.00) when compared with the other groups. All the test-groups presented values of cfu/ml significantly lower in relation to the control groups (p=0.00). It could be concluded, within the conditions of the study, that the coffee solutions tested reduced significantly the adherence of Streptococcus to dental enamel and dentine.

The aim of this study was to evaluate the antimicrobial activity of different coffee solutions and their effects on the adherence of Streptococcus mutans to glass surface. Coffee solutions were prepared with three commercial products (Pilão, Mellita and Café do Ponto) by two different methods (simple and boiled) (n=15). A control group was also included in the study. For antimicrobial activity testing, tubes containing coffee solution and culture medium were inoculated with a suspension of S. mutans ATCC 35688 and incubated for 1min, 1h, 2h and 4h. Serial dilutions and plating on BHI agar were performed. S. mutans adherence to glass in presence of the different coffee solutions was also tested. The number of adhered bacteria (CFU/mL) was determined by plating method. The results were statistically analyzed by ANOVA and Tukey's test. The tested coffee solutions did not reduce the number of colony forming units of S. mutans in relation to the control at all evaluation periods. All the solutions reduced significantly the adherence of S. mutans to the glass surface in relation to control. The tested coffee solutions did not present any antimicrobial effect on Streptococcus mutans, however, all the coffee solutions reduced significantly the adherence of S. mutans to the glass surface.

Estudo exploratório-descritivo do tipo transversal com o objetivo de caracterizar as gestantes acompanhadas em uma Unidade Básica de Saúde da Família, identificar as informações adquiridas pelas mesmas durante o acompanhamento multiprofissional do pré-natal em relação aos cuidados com o bebê e conhecer qual a fonte destas informações. A amostra constituiu-se de 15 gestantes. Foi utilizado para coleta dos dados um questionário estruturado. Os resultados permitiram identificar que a maioria das gestantes tem idade entre 25-35 anos, casadas, primigestas, alfabetizadas, católicas e não trabalham; 66,7% relatam não terem participado de grupos de orientações para gestantes; 40,0% referem ter informações sobre o desenvolvimento do bebê e sinais de parto, porém 53,3% delas nunca tinham tido informações sobre os cuidados com a boca do bebê. Das informações obtidas, a maioria foi através de médicos e de enfermeiros. Estes dados mostram que ações educativas devem ser intensificadas para conscientização e mudança de comportamento das mães...
This is a descriptive, exploratory, transversal study. Its objective is to characterize pregnant women who were accompanied in a Basic Unit of Family Health in order to identify information acquired by the same subjects during their multi-professional pre-natal accompaniment in relation to the care given to their babies and to know of the sources of the information acquired. The sample consisted of 15 pregnant women. The data was collected through a structured questionnaire. The results showed that the majority of the pregnant women were aged 25-35 years, married, experiencing their first pregnancy, literate, catholic, and non-workers; while 66,7% reported not to have participated in orientation groups for pregnant women; 40,0% reported to have information on child-development and signals of childbirth, with 53.3% reporting to have never had information on care for the baby's mouth. The majority of the information was received directly from doctors and nurses. The data shows that educational actions must be intensified for awareness and changes in mothers' behavior...
El presente artículo es un estudio descriptivo-exploratorio de tipo transversal, cuyo objetivo es caracterizar las mujeres embarazadas en una Unidad Básica de Salud de la Familia, identificando las informaciones adquiridas por las mismas durante el acompañamiento multiprofesional del prenatal, en relación a los cuidados con el bebé, y también para conocer cuál es la fuente de estas informaciones. La muestra fue constituida por 15 embarazadas. Para la recolección de los datos fue utilizado un cuestionario estructurado. Los resultados obtenidos permitieron identificar que la mayoría de las embarazadas tiene entre 25 a 35 años de edad, son casadas, primerizas, alfabetizadas, católicas y no trabajan. Del total, 66.7% declararon no haber participado de grupos de orientaciones para las embarazadas; 40,0% dicen tener informaciones sobre el desarrollo del bebé y señales del parto; sin embargo, 53,3% de ellas, dicen que nunca obtuvieron informaciones sobre los cuidados con la boca del bebé. De las informaciones obtenidas por ellas, la mayoría fue a través de los doctores y las enfermeras. Estos datos demuestran que las acciones educativas deben ser intensificadas para la concienciación y cambio de comportamiento de las madres...
