ABSTRACT
Aim: The aim of this study was identify contamination on absorbent paper points used by students of Dental Clinic III of the Faculty of Dentistry of Federal University of Rio Grande do Sul in the semester 2015/1, in order to warn students and professionals of the area on the importance to sterilize these materials. Material and Methods: In a clinical environment, 180 absorbent paper points we collected (80 of them from the first series and 80 from the second one), from 40 students. After the collection, each one was singly immersed in a microtube containing 1.5 ml of the BHI (Brain Heart Infusion) culture. Positive control was composed by one paper point contaminated by saliva, and negative control was composed by a closed microtube, only with BHI. The microtubes were incubated at 37ºC in bacteriological incubator during 14 days. The microtubes that presented turbidity were considered positive, and those which did not present turbidity were considered negative. Results: The results were analyzed by the Fisher Exact Test, which demonstrated that paper points from the second series presented higher agreement contamination between the paper points collected from each box, when compared to the analyzed boxes from the first series (p=0.03). All the samples observed presented growth of Bacillus spp in the microorganism identification. Conclusions: It is possible conclude that absorbing paper points, when exposed to clinical environment suffer contamination, and the autoclave sterilization is necessary before the use, regardless the commercial brand, in order to ensure the aseptic chain maintenance.
ABSTRACT
Purpose: The aim of this article was to present the conceptual model and development of an oral health database for storage, organization, and recovery of data from dental clinical records of a university dental school. Method: This is a joint project of the Graduate Programs in Dentistry and in Computational Science of the Pontifical Catholic University of Rio Grande do Sul (PUCRS). During a period of three months in 2008, semi-structured interviews were conducted with the dental faculty of five clinical areas of the PUCRS Dental School (FO-PUCRS). Collected data were used to build the database language and architecture. Results: Conceptual, logical, and physical database models were developed, as well as the generation of a script in SQL (Structured Query Language). After generating the script, the tool Oracle SQL Developer (Oracle Corporation, Redwood Shores, CA, USA) was used to import and create the FO-PUCRS OHDB (Oral Health Database) implemented in the Oracle 10g, a relational database management system (RDBMS). Conclusion: The FO-PUCRS OHDB represents an important advancement towards automating the institutional operational demands and will contribute to organize the clinical and social information of the patient population for administrative, educational, and research purposes.
Objetivo: Este artigo teve como objetivo documentar o trabalho realizado em conjunto pelos Programas de Pós-Graduação em Odontologia (PPGO), e Ciência da Computação (PPGCC) da Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS), visando à construção de um ambiente de armazenamento, organização e recuperação de dados provenientes de prontuários odontológicos. Método: Durante 3 meses em 2008 foram realizadas entrevistas semi-estruturadas com docentes de cinco áreas de atendimento odontológico da Faculdade de Odontologia (FO-PUCRS) para análise e coleta de requisitos. Resultados: Com base nas informações obtidas neste processo, foram desenvolvidas as modelagens conceitual, lógica e física do banco de dados, bem como a geração de um script em SQL (Structured Query Language). Após a geração do script, foi utilizada a ferramenta Oracle SQL Developer (Oracle Corporation, Redwood Shores, CA, USA) para sua importação e criação do BDSB (Banco de Dados em Saúde Bucal) implementado no SGBD (Sistema Gerenciador de Banco de Dados) relacional Oracle 10g. Conclusão: A construção do BDSB junto ao PPGO-PUCRS representa um importante avanço em direção a automatização das demandas operacionais da organização, mas principalmente a exploração de uma fonte valiosa de conhecimento, rica em informações clínicas e sociais.
