An evaluation of three materials as barriers to coronal microleakage in endodontically treated teeth.

Journal Article (Journal Article)

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