To prove the effectiveness of a dental sealer, it must pass through several tests, among them the fluid penetration method. This test shows the hermetic capability of dental cement. This paper presents the construction of a prototype for such test to measure the quantitative evaluation of microleakage based on Pashley test. The system consists of an oxygen cylinder connected to a pressurized system and linked to a conditioning box. Inside the box, there is a USB camera with LED light, one entry of the box holds attachments for a syringe and a tooth with cement, is placed at the box output. A bubble air is introduced to the system by the syringe and the USB camera records the bubble displacement, and the microleakage calculation is made using digital image processing on LabVIEW. The prototype is tested with three different types of dental cement and can be concluded its correct performance for evaluating microleakage.]]></p></abstract>

Para poder probar la efectividad de un sellador dental, este debe de pasar por una serie de pruebas, dentro de las cuales se encuentra el método de penetración de fluidos. Esta prueba demuestra la capacidad de sellado de un cemento dental. El objetivo de este artículo consiste en presentar el trabajo de construcción de un prototipo para esta prueba que midiera cuantitativamente la microfiltración basada en la prueba de Pashley. El prototipo consiste de un tanque de oxígeno conectado a un sistema de presión que va hacia una caja acondicionada. Dentro de la caja, se encuentra una cámara USB con luz LED, una entrada de la caja, tiene adherida una jeringa y en la salida de la caja se ubica un diente obturado con el sellador. Se introduce una burbuja de aire en el sistema mediante la jeringa y la cámara USB monitorea el desplazamiento de la burbuja y el cálculo de la microfiltración es hecho mediante procesamiento digital de imágenes en LabVIEW. El prototipo fue probado con tres selladores dentales diferentes y se puede concluir que funciona correctamente para evaluar la microfiltración.]]></p></abstract>
