Abstract: Objective: To observe the coronal microleakage of four kinds of temporary restorative materials after endodontic treatment under the stereomicroscope. Methods: Eighty freshly extracted teeth were collected and divided into four experimental groups. Four kinds of temporary restorative materials were used after endodontic treatment, which were glass ionomer cement (GIC), HY-BOND (HB) temporary cement, Cavition, and Clip F. After restored in water bath of 37℃ for 24 hours, the specimens were soaked in 1% Carbon ink for 7 days under room temperature. Then the specimens were cut buccolingually into two pieces with carborundum disc. The degree of microleakage was observed with stereomicroscope. Results: There were significant differences among four temporary materials (P<0.05). The degree of the coronal microleakage was: HY-BOND temporary cement>Cavition>GIC>Clip-F (P<0.05). Conclusion: Clip-F is an effective temporary restorative material.
