Abstract Introduction: Maintaining an adequate coronal access seal is an integral part of multiple-visit endodontic therapy or after root canal treatment until crown reconstruction. This is provided by filling the access cavity with temporary restorative materials. The thickness of the temporary restorative materials is one of the important factors in preventing of coronal microleakage. Objective: This research was conducted to determine the effect of the thickness of three temporary restorative materials of Cavizol, Cavtemp and Coltosol on coronal micro leakage of extracted human teeth. Materials and Methods: In this Invitro study, 100 multi rooted posterior human teeth, were randomly divided into nine experimental groups (n=10) and two negative and positive control group (n=5). According to manufacture’s instruction, the access cavities in experimental groups were filled with three temporary materials, Cavizol, Cavtemp, Coltozol in 2, 3, 4 mm thickness each. Linear dye penetration and clearing technique were used to evaluate coronal leakage of temporary filling materials. Data was analyzed with one way ANOVA test. Results:Comparison of experimental groups in different thicknesses (2, 3, 4 mm) showed no statistical difference (p<0.05) of coronal leakage between different groups as regard as to level . Conclusion: There was no preference between the materials were put for preventing coronal micro leakage. There was no limitation for their essential thickness in access cavity. So they may be suited for clinical situations in access cavities which have the depth of 2mm or more.
