Forty-five central maxillary incisors extracted from human beings were selected. After having undergone standard chemico-mechanical preparation, these incisors were filled with the calcium hydroxide dressing, together with saline solution, in 5mm apicals. After sectioning of the crowns, temporary restorations with intraradicular retainers were fixed with Dycal, Temp Bond and Lysanda. The entire external surface of the roots and crowns, except for a 2mm area near the cervical adaptation, was made impermeable. After being immersed in a 2% Rodamine B solution for 7 days, the specimens were longitudinally sectioned, and infiltrations were analyzed. All results were submitted to pertinent statistical analysis. None of the cements tested was capable of impeding dye infiltration.
