Estudio de la microfiltración coronal utilizando tres materiales de obturación temporal. Revisión sistemática.

Abstract

INTRODUCTION: The first cause of coronal microleakage is the poor adaptation of the temporal obturation materials to the dental structure, making possible the bacterial diffusion. Likewise, the shrinking if the material due to physical and/or chemical changes, disintegration and corrosion of some materials, the elastic deformation of the tooth caused by the chewing forces, can increase the space between the tooth and the restoring material used. OBJECTIVES: Analyze the relation between the endodontic failures and the coronal microleakage using temporal obturation materials. MATERIAL AND METHODS: This is a qualitative, descriptive and no experimental work about the coronal microleakage using three temporal obturation materials: Cavit, Coltosol and IRM.With a transversal-retrospective cut. RESULTS: During the 1st,2nd and 3rd week the Cavit material was the one that presented a 0 to 2 mm microleakage, making it the one with the least microleakage. In the 1st and 2nd week of the tests with IRM it presented a 2.01 to 4 mm of microleakage, wich means it is the one with the most microleakage. Both of Coltosol and IRM presented a 4.01 to 6mm of microleakage during their 3 weeks of tests. CONCLUSION: One of the causes of endodontic failures is due to coronal microleakage. The advised length of time to keep temporal obturation materials in the mouth is at most one week and its advisable to use Cavit since it is the material with the least depth of microleakage.
