Relação entre a presença da equipe de saúde bucal na estratégia saúde da família com o nível de conhecimento dos agentes comunitários de saúde

Objective: to identify the relation between the level of knowledge of community health workers on oral health and the presence of the Oral Health Team in the Family Health Strategy. Methods: we performed a survey with 173 community health workers allocated in public health services of five municipalities in the northwest of São Paulo, Brazil, through a self-administered and structured instrument. The survey instrument contemplated questions related to the presence of the Oral Health Team in the Family Health Strategy and questions regarding oral health. Results: the majority of community health workers was inserted in strategies with the presence of Oral Health Teams (60.1%). We found that the oral health knowledge of most participants was good (48%). Conclusion: there is relation between the level of knowledge of community health workers and the presence of the Oral Health Team in the Family Health Strategy.

Stress levels and quality of sleep in subjects with temporomandibular joint dysfunction

Purpose: The aim of this study was to test the association between quality of sleep and stress in individuals with temporomandibular disorder (TMD). Methods: The study sample consisted of 354 adult subjects (males and females) from the municipality of Piacatu, São Paulo state, in the Southeast region of Brazil. Data were collected using the Fonseca’s Questionnaire to record the level of TMD, the Pittsburgh Sleep Quality Index (PSQI) to assess quality of sleep and the Social Readjustment Rating Scale (SRRS) to record stress level. The data were analyzed by the software Epi Info 2000 version 3.2 using a chi-square test at the 0.05 level of significance. Results: One hundred and eighty (50.8%) subjects had some level of TMD. The statistical analysis showed a significant relationship between the three stress scores and the presence or absence of sleep disorders, considering an overall PSQI score > 5 as an indicator of a subject with sleep problems (P<0.01). Conclusion: Both quality of sleep and stress levels were associated with TMD in this sample.

Perceptions of educators and students about using fluoridated mouthwashes

Purpose: The objective of this study was to assess the perceptions and opinions of public school teachers and students in the city of Araçatuba, SP, Brazil, on the importance of using fluoridated mouthwashes, the difficulties of the method and the procedure in general. Methods: Students from grades 5 through 8 in schools with and without dental services were asked about their opinion on the use of fluoridated mouthwashes. The educators answered questions about the importance of preventive methods in oral health and the difficulties in performing those methods at school. Data were collected using a faces scale, a categorization method, and a Likert scale with five levels of responses to check the level of agreement with the questions. Results: The sample consisted of 264 (40.3%) teachers and 5,788 (73.6%) students. A total of 254 (96.2%) and 72 (27.3%) teachers responded favorably to the first and second questions, respectively. A total of 1,128 (19.5%) students had negative feelings about the fluoridated mouthwash. Conclusion: The majority of the teachers supported the use of fluoridated mouthwashes; however, a large number of teachers believed that the practice disrupts the class routine. Most of the students had a positive opinion about the use of fluoridated mouthwash, although they highlighted some negative aspects, which were overcome by the benefits that the method provides.

Percepção de pacientes HIV-positivos de um centro de referência em relação a tratamento de saúde

Introduction: health professionals, in many cases, have defensive and exclusionary practices, patterns of prejudice and discrimination in response to HIVpositive patients. Objective: to verify the perception of patients seropositives from a reference center for STD/HIV/aids in relation to health care. Methods: there were interviews with questions related to discriminatory attitudes suffered, access and health care. Results: 130 individuals participated in the survey, from which 30 (23.1%) reported events of discrimination suffered outside the center of reference, predominantly from surgeon-dentists and 112 (86.2%) believed to have the same access and health care as other citizens. 62 (47.7%) treated with the dental center of reference, of which 56 (90.3%) felt good being treated in a dental unit only for HIV positive and six (9.7%) were indifferent, believed to be more exposed, or have a bias to attend dental seropositive individuals. Conclusion: it is concluded that many patients have already been discriminated against outside the reference center. However, most of them have a positive feeling towards the treatment received at a specifi c place for treating HIV-positive patients, due to the feeling of being welcome at that place due to the humanization and access to health care.

Conhecimento sobre saúde bucal e práticas desenvolvidas por professores do ensino fundamental e médio

Introduction: The oral health education is a process that aims to transform attitudes and behaviors and to form habits for the benefit of individual health. For this to occur, it is necessary to strengthen and continuous repetition, as possible in the school environment. Objective: To analyze teachers’ knowledge about oral health, practices developed in the school environment, as well as the participation of dentists in guiding teachers of primary and secondary schools. Subjects and method: We used a semi-structured questionnaire with open and closed questions about teacher training, received guidance on oral health during their training, development of oral health issues in the classroom and knowledge on the subject . Results: Of the total respondents (n = 221), only 77 (34.8%) said they had guidance on oral health in their training to be a teacher. 70 (31.7%) said they did not develop oral health issues in the classroom and 91 (41.2%) stated no interaction between dentist and professor. We observed deficiency in teachers’ knowledge about certain issues related to dental health. There was statistically significant association between the dentist’s guidance to teachers and the development of oral health actions and the teacher’s knowledge about the location of the first permanent molar eruption (p <0.01). Conclusion: This study conclude that although most educators develop educational practices on oral health in the school environment, there is a deficiency in understanding by teachers of certain subjects, making it necessary a greater participation of the dentist in the transmission of technical and scientific knowledge to them.

Epigenetic and genetic approach to the transmissibility of dental characteristics in twins: report of two cases

Transmissibility of dental and jaw characteristics is strongly influenced by environmental factors during the years of extra uterine life when odontogenesis occurs. Through biochemical factors, such as enzymes, proteins, hormones and other mediators, genes are activated or silenced to suit the cell or organism to its environment. These changes are not transmitted to our descendants, because of that, these factors are called epigenetic. Among the most cited epigenetic factors are food, pollution, drugs and exercise. The objective of this study was to assess the transmissibility of dental characteristics in two pairs of twins. In one case, 13-year-old boys had the same basic dental and jaw characteristics with prolonged retention of the second upper deciduous molars and the presence of permanent successors. In the other case, 14-year-old boys had prolonged retention of lower deciduous second molars and absence of permanent successors, but only one of them had the germs of third lower molars. The phenotypic difference in the dentition of twins from clinical case 2 could be due to epigenetic factors, showing the absence of genetic determinism in the transmissibility of dental characteristics.

Absentismo laboral por patología odontológica y médica en una industria de gran porte del sector mecánico y mueblero

Introduction: The current Brazilian legislation states that health services must be performed by the Specialized Service of Safety Engineering and Labor Medicine (SESMT). Objective: To analyze the dental and medical reasons for absenteeism, checking the interference of factors such as age, gender and position of the worker, and most of the reasons that led the employee to miss work. Material and methods: The research appears as a descriptive study with a quantitative approach. The dental and medical certificates and statements of attendance were analyzed, duly approved, lodged in a acrylic industry in the city of Araçatuba-SP, from January to July 2011. Results: Of the total number of certificates (n = 1841), only 103 (5.6%) were for dental reasons. Predominance of the age group of 20-29 years, males and with non-administrative function. The reasons most dental and medical certificates stated that led the workers to miss working days were "inclusive and impacted teeth" and "diarrhea and gastroenteritis of presumed infectious origin", respectively. As to factors related to absenteeism, there was a severity index of 2.83, 1.33 frequency and average duration of absences of 2.12. Conclusions: It is concluded that dental reasons had little weight on total absences due to illness that caused the temporary leave of the worker for a shorter period. The age and function variables influence the occurrence of work absenteeism.

Femoral Biomechanic and microtomography from male rats submitted to dietary restricition supplemented with sucrose

Food restriction reduces body weight and influence bone mass and also is correlated with bone mineral density (BMD). Mechanisms have been proposed for the loss of BMD after body weight reduction, including reduced energy intake. Growing 8 wk-old Wistar male rats were randomly divided into Control and Calorie restriction associated with sucrose 30% (CRS). These animals were subjected to intermittent food restriction during 8 weeks and had free access to tap water and sucrose30% in distilled water. The rats were euthanized at the end of week 8, blood collected from abdominal aorta artery, femurs cleaned of adherent soft tissues, scanned using dual energy X-ray absorptiometry, structural and material properties determined by three-point bending testing in the mid-diaphyseal region, bone surface tested in a microhardness tester and microstructure was assessed in a microcomputer tomography. In CRS animals body weight decreased significantly relative to the Control animals. There was a clear option for high-sucrose beverage in CRS animals. No difference was observed in biochemical, densitometric and biomechanical analyzes. Results from micro CT showed only significant difference in connectivity of trabecular bone. It has been suggested that rats submitted to food restriction consumed sugar not because of its inherent palatability, but in order to alter their macronutrient balance and animals need to meet energy demands in high-sucrose.

La Práctica de Recapsular Agujas por Profesionales de la Salud y Condiciones de los Depósitos de Material Corto-Punzante

El objetivo de este trabajo fue verificar la adhesión a la sugerencia de no recapsular agujas, basado en el comportamiento revelado por los cirujanos dentistas de la red municipal de salud bucal de la ciudad de Araçatuba en el estado de Sao Paulo, así como también observar la presencia de depósitos de material corto-punzante, las condiciones de llenado (por sobre el nivel recomendado o no) y su ubicación (cerca o lejos del profesional). Se recolectaron los contenedores de todas las unidades odontológicas de la red municipal. Después de la separación de otros elementos corto-punzante y materiales, además de la selección según como se recapsuló, se procedió al conteo de las agujas con la ayuda de una pinza larga y colocadas sobre una mesa revestida. Del total de 48 unidades odontológicas, se recolectaron 38 contenedores de elementos cortopunzantes con 5591 agujas desechadas. De estas, 2384 (42.7%) estaban recapsuladas por los dos lados, 2.177 (38.9%) en un lado y 1.030 (18.4%) sin recubrimiento. Se concluye que el índice de apego de estos profesionales a la recomendación de no recapsular las agujas es bajo. Los contenedores eran en la mayoría del tipo “Descarpak” y no estaban rellenados encima del nivel indicado; y a la vez se encontraban alejados del responsable de los desechos.

Prevalência de acidentes com material biológico em um município do noroeste de São Paulo, Brasil, no período de 2007 a 2011

The objective of this study is to determine the prevalence of reports of accidents involving biological material which affected health professionals, especially dental health ones, in a city in the north­western region of São Paulo State, Brazil. Data collection was con­ducted through the notification of accidents with biological material from 2007 to 2011. There were 377 notifications, in which 353 (93.6%) had female professionals involved. The most reported type of exposure was the percutaneous in 359 cases (95.2%) followed by blood in 334 cases (88.6%) which is the most mentioned biological material in the reports. Only 21 (5.6%) notifications were from den­tal staff and occurred mostly with the dentist, 14 times (66.7%) and 16 times (76.2%) during clinical procedures. The prevalence of bio­logical accidents among dental teams was little in this time, which suggests the possibility of underreporting, in addition to being sub­ject to the partial fulfillment of the same.

Aplicação de modelos hidrológicos para avaliação de reservatórios de retenção e detenção combinados à obra de recuperação do canal de macrodrenagem no controle de cheias em uma bacia hidrográfica urbanizada

The aim of this paper was to evaluate the effect of retention and detention reservoirs along with the regulation in channel flow upgrade on flood for an urban watershed located at Rio Claro, SP. For this purpose, modeling and simulation techniques were applied for runoff determination and its propagation in channel. The Soil Conservation Service – SCS hydrologic model as well as Pulz and non-linear Muskingum-Cunge model were used. The software IPHS1 was applied on simulations. The results pointed out that the combination of retention increasing and detention reservoir implementation (120,000 m3, corresponding to 1.5% of the watershed area) with the streamflow upgrade (n decreasing from 0,04 to 0,02) can minimize the flood on the investigated Servidão watershed. Further, after the proposed intervention, the flood was eliminated for the investigated times of recurrence: 5, 20, 50 and 100 years. The prognostic indicated that the available area occupation had a minor effect on flow increasing due to the observed high urbanization.

O papel das emissoras educativas no Brasil em tempo de eleições

The concept of educational radio is present in the Brazilian Code of Broadcasting in 1963, valued by an Interministerial 1999.According to the Ministry of Communications, only 176 stations are considered educational universe of 3,000 existing radios in Brazil. In this context, the study proposes to establish a discussion on the educational experiences obtained from the radio, considering the Brazilian radio culture that favors concessions to trade groups and religious politicians. The challenge will be to move toward a program that combines educational content, entertainment, and thus ensures a common universe of communication skills enabling the adult radio listeners their actual interaction with the world around him. The methodology will work in the literature from texts on the subject, and the result of practical observations collected during visits to the broadcasters, programming and analysis.
