Abstract

Objective: The aim on this study was to evaluate the coronal infiltration of restored samples with cast post cores, cemented with different types of cement.
Methods: Forty-eight rooted samples extracted from humans were instrumented with rotatory system and prepared dentist’s drill wide to the confection of the molten core. The samples were divided in three experimental groups and two control groups. Group 1 was cemented with zinc phosphate cement; group 2 with glass ionomer cement, and group 3 with resin cement. The samples were assembled in a double chamber model system, and their leakage detector was the Enterococcus faecalis. The inoculation was renewed every three days during 60 days. The microleakage was daily evaluated through the observation of the culture medium regarding its turbidity.
Results: Microleakage occurred in positive group. There was no microleakage in the negative group. It was detected 66, 66%, 25%, and 41, 66% of microleakage in groups 1, 2 and 3. The statistical analysis carried out by the Wilcoxon-test, revealed a considerable difference between cements, being the zinc phosphate cement the one with the worst results.
Conclusion: The cementation procedure of molten metallic cores can be important to delay the contamination of teeth in need of coronal reconstruction.
