%X Objective: The aim of this study was to assess the coronal leakage of three temporary cements in endodontics: Bioplic  (Biodinamica, Londrina, Brazil), IRM  (Dentsply, Petr¨®polis, Brazil) and Coltosol  (Vigodent, Bonsucesso, Brazil). Methods: Forty human pre-molars were divided into four groups: I (Bioplic  + adhesive system), II (Bioplic , Biodinamica, Londrina, Brasil), III (IRM , Dentsply, Petr¨®polis, Brasil), and IV (Coltosol , Vigodent, Bonsucesso, Brasil). The teeth were immersed in 1% Rodamine and kept at 37ˇăC for 24h. They were then thermal cycled for seven days. Temperatures ranged between 5, 37 and 50ˇăC. After longitudinal sectioning the leakage was measured in mm and statistical analysis was performed using the ANOVA and Tukey tests with a level of significance of 5%.Results: In the group in which Bioplic  was used with adhesive, a lower level of leakage was detected (0.37 ˇŔ 0.24). There was significant difference (p<0.05) between groups I and III, I and IV, II and III. Conclusion: It was concluded that all the tested material showed coronal leakage and that the use of the (Bioplic  Biodinamica, Londrina, Brasil)plus adhesive system showed the lowest level of leakage.
