摘要: Barrier Dentin Sealant, glass ionomer cement, and TERM were evaluated as possible barriers to coronal microleakage. The root canals of 70 extracted teeth accessed, cleaned shaped, then obturated with gutta-percha sealer. divided into four groups, one for each barrier material control group. Subgroups stored in a humidor or immersed artificial saliva 7 days placed methylene blue dye. Sealant groups demonstrated the lowest dye penetration measurements. difference between them was not statistically different. Glass cement greatest different from other two materials.
