摘要: Introduction: Providing adequate coronal seal of temporary filling materials is critical for the success root canal therapy. The aim this in vitro study was to compare ability three restorative over different periods time. Materials and Methods: Ninety-eight molar teeth were selected. Once access cavities prepared, divided randomly into time groups (1 day, 1 week, 4 weeks). Each group then subdivided 10 teeth. subgroup restored using one including Coltosol, Cavizol Zonalin incubated distilled water at 37 o C . samples immersed 2% methylene blue dye. After rinsing drying, sectioned longitudinally examined dye penetration. Kruskal-Wallis Mann Whitney U tests used analyze data. Results: All experimented showed increasing leakage from st day th week. more than Coltosol each interval ( P 0.05), but there no significant difference between Cavizol. Conclusion: are suitable up
