ABSTRACT
To evaluate the knowledge of dentists from the health units (HU) of Porto Alegre -Brazil, regarding the management of avulsion of permanent teeth.Material and Methods:All dentists (n = 117) from HU were invited to answer a self-applied questionnaire regarding the treatment and preservation of avulsed permanent teeth in different clinical scenarios, based on the guidelines of the International Association of Dental Trauma (IADT). The professional data were also collected. The correlation between the performance of each professional and professional data was performed, (StudentÆs t test, PearsonÆs and SpearmanÆs correlations), assuming 5% significance.Results:The response rate was 56.41%. The mean performance rate of the dentists regarding the clinical questions was 69.3%, but 37.4% had poor performance (less than 70% correct). The greatest number of hits was where the patient comes with the already replanted teeth (89.2%); 87.3% agreed in situations where the injured child reaches two hours of trauma with the tooth in a liquid medium, however in cases that period of trauma was more than two hours and tooth was dehydrated, the professionals performance was reduced (64.9%). There was a lack of knowledge about the use of intracanal medication (error rate of 56.9%); 41% are mistaken about the period to start endodontics procedures; 32.8% did the wrong about contention of avulsed teeth and clinical and radiographs follow-up. Dentists with postgraduate performed better than those without (p = 0.011)...

Objetivo: Avaliar, por meio de análise microbiológica, a contaminação nas resinas compostas utilizadas em clínicas odontológicas de uma Instituição de Ensino na cidade de Santa Maria, RS, Brasil. Método: Foi realizado um levantamento quanto ao número de acadêmicos que utilizam cada clínica, bem como o semestre à qual pertenciam. Um total de 100 amostras estavam disponíveis para a análise nas 3 diferentes clínicas. Incrementos de 2 mm foram removidos de cada tubete de resina composta disponível de forma asséptica e imersos em 5ml do meio de cultura BHI (Brain Heart Infusion). Após 24 horas de incubação em estufa bacteriológica à 37ºC foi feita a primeira leitura, e após 48 horas, a última. Um grupo controle negativo para o meio de cultura foi realizado. As amostras nas quais ocorreu o turvamento do meio de cultura foram consideradas contaminadas. Resultados: 51% das amostras analisadas encontravam-se contaminadas, apresentando variação do percentual de ocorrência entre as clínicas incluídas. Conclusão: Em algum momento do procedimento restaurador, executado pelos acadêmicos, ocorre uma falha geradora da contaminação. Assim, há risco de infecção cruzada, havendo a necessidade de buscar alternativas para barrar essa contaminação durante o procedimento.
Purpose: The aim of this study was to assess microbiologically the composite resins used in dental clinics of a University in Santa Maria, RS, Brazil. Method: Were analyze a total of 100 samples available in 3 different clinics. Increments of 2 mm were removed from the tubes of resin and cultured in 5 ml of BHI (Brain Heart Infusion). After 24 hours of incubation in a bacteriological incubator at 37°C, was made the first analysis, and after 48 hours, the last one. A negative control group for the method was performed. The samples on which turbidity was found were considered contaminated. Results: The contamination was present in 51% of composite resins analyzed, showing a difference in the incidence between clinics. Conclusion: In the restorative procedure, performed by students, there is a fail wich generates contamination. This failure has potential to cause crossed infection. Thus shows the need of search for alternatives to prevent the contamination during the procedure.
