O tratamento clareador se destaca por ser uma técnica conservadora, que pode proporcionar elevação da autoestima e melhorar o convívio social das pessoas. No entanto, pacientes expostos a essa terapia experimentam diferentes níveis de ocorrência e de intensidade de sensibilidade dentária. Essa sintomatologia é preocupante, pois tem sido apontada como o reflexo de uma eventual resposta pulpar frente ao tratamento realizado. Por outro lado, a presença de dor é desestimulante aos pacientes, prejudicando a evolução do tratamento e reduzindo o sentimento de satisfação. Apesar dessa importância, a maior parte dos estudos de sensibilidade dentária ainda emprega métodos subjetivos, dificultando a reprodutibilidade e interpretação dos resultados. Objetivo: nesse sentido, o presente artigo objetiva analisar a resposta neurossensorial proporcionada pela aplicação de estímulos térmicos gerados pelo equipamento TSA II (Medoc TSA II Neurosensory Analyzer, Israel), em um paciente submetido ao tratamento clareador, seguido pelo uso ou não uso de um dessensibilizante. Métodos: as análises foram realizadas antes do clareamento (AC), depois do clareamento (DC) e depois da aplicação ou não do dessensibilizante (DD) em cada hemiarcada estudada. Os dados foram submetidos ao teste t de Student, com nível de significância de 5%. Resultados: observou-se que o clareamento dentário alterou o limiar de sensação ao frio, provocando aumento da sensibilidade dentária, e que o uso do dessensibilizante foi efetivo. Conclusão: o uso de testes sensoriais quantitativos mostrou-se promissor para o estudo da sensibilidade dentária, podendo colaborar no estabelecimento de terapias seguras e confortáveis.

Some remarks on how Cultural History has been used in Mathematics Education are the main focus of this paper. It tries to discuss, basically, three works (In Cold Blood, by Truman Capote; O crime do restaurante chinês, by Boris Fausto; and Os protagonistas anônimos da História, de Ronaldo Vainfas) in order to present some perspectivas about narratives and textual elaboration in the field of Historiography.

Objective: to evaluate the standardization of vaccination rooms in the Municipality of Marília, State of São Paulo, Brazil. Methods: descriptive and exploratory study, realized in 2008-2009; the instrument used was the Supervision in Vaccination Rooms, of the Ministry of Health; variables analyzed were general aspects of the vaccination room, technical procedures, cold chain, information system, post-vaccination adverse events, special immunobiologicals, epidemiological surveillance and health education; the score achieved classifies the room (90.0-100.0% = ideal; 76.0-89.0% = good; 50.0-75.0% = fair; <50.0% = insufficient); overall index for each point was calculated as the average score of all rooms. Results: technical procedures, information system, post-vaccination adverse events and special immunobiologicals were scored as ideal; cold chain, epidemiological surveillance and health education were scored as good; and to general aspects of the vaccination room, the evaluation was fair. Conclusion: general index for vaccination rooms in the municipality was considered ideal.

Usage of pesticies in excessive doses or in an inadequate way to control diseases, pests and weeds, has promoted significant environmental damage, contamination of animals, intoxication of farmers, among others. These factors lead to occur the resistance of weeds, pests and pathogens, the appearance of iatrogenic diseases, biological imbalance and reduction in biodiversity. Seeking less aggressive alternatives, plant extracts have been used successfully. Compared to synthetic products, they offer great advantages as generating new compounds, which pathogens are unable to inactivate, and are less toxic, of rapid degradation in the environment, they have broad modes of action, and are derived from renewable resources. It should be emphasized that there are some limitations on its use. The extracts have potencial as insecticide, fungicide, herbicide and nematicide and are considered of good efficiency. The methodologies for obtaining can be achieved through cold extraction, open and closed hot system. The use of plant extracts reappears as a promising and unique option for integrated management in plant protection, being considered as an alternative to control plant pathogens, demonstrating excellent results without causing harm to the environment and living beings.

In the postharvest management, the fruits can be exposed to injuries that depreciated the quality and the shelf life. Thus, it was evaluated the modified atmosphere effects on guavas var. Paluma subjected to different mechanical damages. Once harvested, the fruits were selected, sanitized and submitted to the treatments T1 (control) - without injuries or packaging in bags of low density polyethylene (LDPE); T2 - without injuries + LDPE bags; T3 - damage by fall of 1 m + LDPE bags; T4 - damage by compression of 9 N + LDPE bags; T5 - damage by fall of 1 m + damage by compression of 9 N + LDPE bags and T6 - damage by fall of 1 m + damage by compression of 9 N without LDPE bags. The treatments were kept in cold storage at 10 ± 1 o C and 94 ± 2% de R.H. The analysis of CO2/ethylene production, enzymatic activity, total and soluble pectins, pulp firmness, titratable acidity (TA), soluble solids (SS), reducing sugars and ascorbic acid were performed every 10 days of refrigeration, and an additional day outside cold storage (22 ± 1o C and 75 ± 3% R.H.) for 30 days. Guavas packed in LDPE bags, not subject to mechanical damage, presented the best quality standards. The fruits suffered only one kind of damage, when packaged, presented satisfactory pattern compared to the fruits without package and not exposed to any mechanical damages. Applying the two kinds of damages, the LDPE packaging was not adequate to decrease the metabolic rate of these fruits, making them unfit for marketing.
