| dc.description | Objetivo: El objetivo de este estudio es Evaluar la microfiltración bacteriana en conductos de dientes unirradiculares obturados con el sistema Cpoint™ en un estudio in vitro. Materiales y Métodos: Se seleccionó un total de 30 raíces de dientes unirradiculares humanos con conducto único, permeables, que presenten curvaturas leves y ápices cerrados. Se les realizó apertura convencional con fresa redonda. Los dientes se prepararon con el sistema ProTaper Universal® de acuerdo a las especificaciones del fabricante. Luego, los dientes se dividieron al azar en 3 grupos. Grupo experimental (n=20), grupo control positivo (n=5), grupo control negativo (n=5). Las muestras en los diferentes grupos se obturaron de la siguiente manera: Grupo experimental, instrumentados y obturados con la técnica de obturación de cono único CPoint™. Grupo control positivo, instrumentados, que no fueron obturados. Grupo control negativo, instrumentados, obturados con la técnica de obturación de cono único CPoint™ y sellados completamente con barniz de uñas. Después de 7 días de la obturación; los dientes son llevados a una cámara de filtración bacteriana con Enterococcus faecalis durante 48 horas con humedad del 100%. Los valores de microfiltración bacteriana del sistema de obturación de cono único CPoint™ se evaluaron utilizando microscopia electrónica de barrido a diferentes magnificaciones (2000X, 3000X, 5000x, 7000X) obteniendo un total de 72 imágenes de los diferentes tercios radiculares y se determinó la ausencia o presencia de E. Faecalis en la interfase cemento-dentina y cemento- CPoint™. Resultados: se encontró que en el tercio coronal y medio se presentó solo 1 caso de filtración del microorganismo, que corresponde al 5.56% y 6.25% de un 100% respectivamente. Esta microfiltración pudo ser identificada en las cuatro magnificaciones utilizadas para este estudio (2000x, 3000x, 5000x, 7000x). Para el tercio apical no se identificó microfiltración en ninguna de las muestras en las diferentes magnificaciones. Conclusión: el sistema CPoint™ genera un selle hermético a lo largo del conducto radicular reduciendo la microfiltración bacteriana considerablemente. | spa |
| dc.description.abstract | Aim: The aim of this study is to evaluate the bacterial microfiltration root canals sealed single-rooted teeth with Point ™ system in an in vitro study. Materials and Methods: A total of 30 roots of human single-rooted teeth with only permeable root canal, showing slight curvature and closed apices were selected. They underwent conventional opening round bur. The teeth were prepared with ProTaper Universal® system according to the manufacturer's specifications. Then the teeth were randomly divided into 3 groups. Experimental group (n = 20), positive control group (n = 5), negative control group (n = 5). The samples in the different groups were filled as follows: Experimental group, instrumented and filled with sealing technique CPoint™ single cone. Positive control group, instrumented, which were unsealed. Negative control group, instrumented, sealed with sealing technique Point ™ single cone fully sealed with nail varnish. After 7 days of the sealed; the teeth are brought into a bacterial filtration chamber of Enterococcus faecalis for 48 hours with 100% humidity. Values bacterial microfiltration of Point ™ system were evaluated using scanning electron microscopy at different magnifications (2000X, 3000X, 5000X, 7000X) obtaining a total of 72 images of different root thirds and determined the absence or presence of E. faecalis in the dentin-cement interface and cement-CPoint™. Results: It was found that in the coronal and middle third showed only 1 case of filtration of the microorganism, which corresponds to 5.56% and 6.25% from 100% respectively. This microfiltration could be identified in the four magnifications used for this study (2000x, 3000x, 5000x, 7000x). For apical microfiltration it not identified in any of the samples at different magnifications. Conclusion: Point ™ system generates a hermetic seal along the root canal significantly reducing bacterial microfiltration. | spa |
