ABSTRACT

Aim: The purpose of this study was to compare the effectiveness of a high-volume evacuation and a conventional intraoral suction system and aspirating tips for capturing aluminum oxide particles during use of an air-abrasion device. Methods: A phantom head was fixed at the dental chair head with secured a metallic device with 5 horizontal shafts, corresponding to operator’s clock related working positions, and one vertical shaft to simulate the operator’s nasal cavity. Petri plates were fixed to the shafts at distances of 20, 40 and 60 cm from the center of the oral cavity of the phantom head to collect the aluminum oxide particles spread over during air abrasion. The dust was aspirated with two types of suction tips used with both suction systems: a conventional saliva ejector and a saliva ejector customized by the adaptation of a 55-mm-diameter funnel. Results: The amount of particles showed that the greatest abrasive particle deposition occurred at a distance of 20 cm from the center of the oral cavity of the phantom head at 9 o’clock operatory position with the conventional saliva ejector attached to high-volume evacuation system. Conclusions: The greatest deposition of aluminum oxide particles occurred at the shortest distance between the operator and the center of the oral cavity, while using the high-volume evacuation system associated to the conventional suction tip.

ABSTRACT

Nesse estudo, avaliou-se a deposição de partículas de óxido de alumínio no campo operatório do cirurgião-dentista durante o emprego de um aparelho de abrasão a ar e sucção odontológica convencional parasucção do pó gerado. Um dispositivo metálico, simulando as posições de trabalho do cirurgião-dentista,possibilitou a captação das partículas durante o abrasionamento de dentes artificiais. Sugadores de salivaconvencional e modificado por funil foram empregados no sistema de sucção convencional da equipe odontológicacom a finalidade de captar o pó de óxido de alumínio. Os resultados foram expressos por meio deanálise estatística gráfica em função da quantidade em massa de partículas de óxido de alumínio obtida emfunção da distância e posição de trabalho do operador ao centro da boca de um manequim. A maior deposiçãode partículas ocorreu a 20 cm de distância do operador em relação ao centro da boca e na posição detrabalho 9h, quando se empregou o sugador de saliva convencional.


In this study the aluminum oxide particle deposition was evaluated in the operatory position of the dentistduring an air abrasion system application with conventional dental suction (CDS) for the aspiration of thedust. A metallic device, simulating the operatory position of the dentist was used to particles deposition duringthe abrasion of an artificial tooth. A conventional saliva ejector and a modified ejector by funnel-shapedattachment were used in conventional dental suction (CDS) to dust suction. The results were expressed inaluminum oxide particles mass in relation to the operatory position and distance from operator to the centerof the mouth. Statistical graphical analysis showed that the greatest particle deposition occurred at 20cm ofdistance from the operator to the center of the mouth, in the 9 o'clock operator position when the conventionalsaliva ejector was used.

ABSTRACT

Registrar e contabilizar procedimentos, materiais e medicamentos em grandes hospitais, é uma tarefa complexa que é composta das diferentes funções e modelos de dados. As informações necessárias às tarefas de gerência de faturamento, envolvem inúmeras unidades administrativas, técnicas e operacionais. Para introduzir uma solução automatizada desta gerência, propôs-se para o Incor, um modelo baseado na utilização de banco de dados relacional com ferramenta de 4GL.
