The Effect of Calcium Chloride on Push-Out Bond Strength of Calcium-Enriched Mixture Cement and Mineral Trioxide Aggregate
INTRODUCTION: This in vitro study investigated the effect of adding 10% calcium chloride (CaCl(2)) on push out bond strength of calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA) to root canal dentin. METHODS AND MATERIALS: A total of 120 root dentin slices with 2 mm thicknes...

Sumario: | INTRODUCTION: This in vitro study investigated the effect of adding 10% calcium chloride (CaCl(2)) on push out bond strength of calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA) to root canal dentin. METHODS AND MATERIALS: A total of 120 root dentin slices with 2 mm thickness were prepared from sixty single-rooted human teeth. Dentinal discs were enlarged to achieve 1.3 mm diameter. The specimens were randomly allocated into eight groups (n=15). Dentin discs were filled with either CEM cement or MTA with or without CaCl(2) and the push out test was performed after 3 and 21 days. Data were analyzed with two-way ANOVA test. The level of significance was set at 0.05. RESULTS: There was an interaction effect amongst all groups (P=0.028). After 3 days, CEM cement showed a significantly lower bond strength than other groups (P<0.05) while MTA demonstrated significantly higher bond strength than CEM cement with or without CaCl(2) (P=0.001). After 21 days, CEM cement with or without CaCl(2) had no significant difference with other groups (P>0.05). However, the bond strength of MTA decreased when CaCl(2) was added (P=0.011). CONCLUSION: The addition of 10% CaCl(2) increased the push out bond strength of CEM cement and improved it over time; while, this substance aggravated this property for MTA. |
