Resumen
El propósito de este trabajo investigativo es analizar cuál de estos cementos de obturación provisional, ionomero de vidrio, oxifosfato de zinc y cavit, utilizados en endodoncia, tienen menor índice de microfiltración coronaria. De acuerdo con los resultados obtenidos el cemento provisional ionomero de vidrio es una buena elección entre los materiales de obturación provisional por su bajo costo, facilidad de manipulación y dureza superior a los otros cementos de obturación provisional como el oxifosfato de zinc y cavit. Es importante saber que cualquier tipo de cemento provisional no debe mantenerse mucho tiempo en boca ya que corre el riesgo de perder la obturación y por ende contaminar nuevamente el conducto radicular. Para este trabajo se utilizaron 15 piezas dentarias (premolares), las piezas dentarias se las dividió en 3 grupos, cada grupo para distinto tipo de cemento provisional. Las piezas dentarias tuvieron su respectiva asepsia, estas fueron instrumentadas y obturadas, después de la preparación las piezas dentarias fueron sumergidas en tinta china durante un periodo de 7 días, después de este periodo las piezas fueron limpiadas para retirar todo el colorante y luego fueron seccionadas para luego ser observadas mediante un microscopio electrónico. Los resultados obtenidos de este estudio fueron que el cemento ionomero de vidrio utilizado como cemento provisional es el más efectivo contra la microfiltración coronaria, en los resultados obtenidos observamos que el cemento ionomero de vidrio tuvo 1,20mm de microfiltración, por otro lado las piezas dentarias obturadas con oxifosfato de zinc tuvieron 2,60mm y el cemento cavit 2,80mm.

The objective of this research is to analyze which of the temporary filling cements, glass ionomer, zinc oxyphosphate cavit used in endodontics, and have lower rates of coronary microfiltration. According to provisional results of the glass ionomer cement it is a good choice with temporary filling material for its low cost, ease of handling and other than temporary filling cements such as zinc and cavit oxyphosphate hardness. It is important to know that any type of temporary cement should not stay long in the mouth as it runs the risk of losing the seal and thus contaminate the canal again. For this work 15 pieces teeth (premolars) were used, the teeth were divided into 3 groups, each group for different types of temporary cement. The teeth had their respective asepsis; these were implemented and sealed, after preparation the teeth were immersed in ink for a period of 7 days, after this period the pieces were cleaned to remove all dye and then were sectioned then be observed through an electron microscope. The results of this study were that the glass ionomer cement used as temporary cement is the most effective against coronary microfiltration Our findings indicate that the glass ionomer cement was 1.20 microfiltration, on the other hand the teeth oxyphosphate sealed with zinc and cement had cavit 2,60mm 2,80mm. Keywords: microfiltration, glass ionomer, oxyphosphate, cavit.
