Abstract

There is little in the literature on retention of Co-Cr (cobalt-chromium) cast metal pins cemented with resin
or conventional alloy and, although many methods have been tested and used, there is no specific technique
or material indicated in all clinical cases. Objective: The aim of this study was to evaluate the retention of
the molten metal pins cemented with zinc phosphate and resin cement after the root impregnation/treatment
with chitosan. Methods: A Pull Out was used with a universal test machine, with a speed of 0.5mm / Minute
and with a 50kgf load cell. Results: The obtained results were submitted to the Kolmogorov-Smirnov test
to verify the homogeneity of the data, and it was verified that the values were normal. Conclusion: It was
concluded that the cementation of the molten metal pins of Co-Cr with resinous cementations agent is more
efficient than the action of the zinc phosphate cement when the chitosan is used as an irrigating agent.
