Objective: The aim of this study was to assess the coronal leakage of three temporary cements in endodontics: Bioplic (Biodinamica, Londrina, Brazil), IRM (Dentsply, Petrópolis, 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, Petrópolis, Brasil), and IV (Coltosol , Vigodent, Bonsucesso, Brasil). The teeth were immersed in 1% Rodamine and kept at 37°C for 24h. They were then thermal cycled for seven days. Temperatures ranged between 5, 37 and 50°C. 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 ± 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.
