Abstract(s)
Introdução: A utilização do dique de borracha permite uma maior segurança durante a sua
utilização numa consulta de medicina dentária, não só ao nível de infeção cruzada, assim
como conferir ao médico dentista um campo operatório assético, limpo, seco e com boa
visibilidade. Aquando do uso de instrumentos rotatórios, estamos inadvertidamente a
formar aerossóis. Com este trabalho pretendeu-se avaliar se o dique de borracha interfere
na distribuição de aerossóis bacterianos gerados durante a execução de cavidades de
dentisteria ao usar instrumentos rotatórios.
Materiais e métodos: Foi realizada uma pesquisa bibliográfica na base de dados
Pubmed/MEDLINE, com os seguintes termos: “rubber dam”, “dental dam” e “aerossol
contamination”. Posteriormente foi realizada uma avaliação da distribuição de aerossóis
produzidos durante a execução de tratamentos de cárie sob a forma de contagens em
placas de Petri com meios específicos para bactérias e fungos. Numa fase final do trabalho
desenvolvido, identificaram-se isolados clínicos através de sequenciação nucleotídica de
modo a analisar-se os microrganismos que podem estar presentes nos aerossóis.
Resultados:
O número de unidades formadoras de colónias foi superior nos grupos sem utilização do
dique de borracha em detrimento de se o utilizar. No operador e no assistente não houve
diferença estatisticamente significativa, no tabuleiro com diferença significativa. Após a
sequenciação nucleotídica das culturas foram encontrados os seguintes microrganismos:
Staphylococcus, Pseudomonas, Micrococcus e Bacillus.
Conclusão:
É benéfico utilizar-se o dique, assim como outros meios-barreira (bochechos com solução
antimicrobiana, luvas, máscara e viseira) de modo a diminuir o risco de contaminação para
a equipa clínica, assim como conferir maior segurança ao paciente no tratamento.
Introduction: The usage of the rubber dam provides a greater safety during its use in a dental appointment, not only in terms of cross-infection, as well as providing the dentist with an aseptic, clean, dry environment and with a good visibility of the operating field. When using rotary instruments, we are inadvertently forming aerosols. The purpose of this study was to evaluate if the rubber dam interferes in the distribution of dental aerosols generated during caries treatment, while using rotary instruments. Materials and methods: A research was carried out in the Pubmed/MEDLINE database with the following terms: “rubber dam”, “dental dam” and “aerosol contamination”. After that, an evaluation of the distribution of bacterial aerosols produced during the execution of caries treatments was carried out in the form of counts in petri plaques with specific environments for bacteria and fungi. In the final phase of the study, clinical isolates were identified through nucleotide sequencing, in order to analyze the microorganisms that may be present during a dental treatment. Results: The number of colony forming units was superior in the groups not using rubber dam in comparison to its use. In the operator and assistant there was no statistically significant difference, while in the tray there was significant difference. After nucleotide sequencing of the cultures was found the following microorganisms: Staphylococcus, Pseudomonas, Micrococcus e Bacillus. Conclusion It is beneficial to use the rubber dam, as well as other barrier-methods associated with it (mouthwashes with an antimicrobial solution, gloves, masks, and visor) in order to reduce the risk of contamination for the clinical team, as well as to provide greater safety for the patient during the treatment.
