The purpose of this in vitro study was to evaluate quantitatively the effectiveness of three different restorative materials used as an intracoronal barrier to prevent microleakage of endodontically treated teeth. Fifty-five extracted human single-canal teeth were used in this study. The teeth were endodontically prepared and obturated. Forty-five teeth were randomly assigned to three experimental groups: group 1: sealed with Ketac-Cem (3M ESPE, St Paul, MN) (n = 15), group 2: sealed with Clearfil Protect Bond/Clearfil AP-X (Kuraray, New York, NY) (n = 15), and group 3: sealed with Maxcem (Kerr, Orange, CA) (n = 15). Ten teeth were also randomly assigned to a negative control group (n = 5) and a positive control group (n = 5). Microleakage was tested by using a sterile two-chamber bacterial method and Enterococcus faecalis was used as a microbial marker. Samples were incubated aerobically at 37 degrees C for 120 days. Bacterial leakage was determined by change in turbidity in the medium. Statistical analysis was performed using a Wald chi-square test. No significant difference (p > 0.05) in bacterial leakage was found between the three experimental groups tested. All positive controls leaked within 60 days and broth of the negative control group remained clear throughout the entire experimental period.
