Evaluation of the ability of glass-ionomer cement to bond to glass-ionomer cement.

This study investigated the cohesive bond strengths of glass-ionomer cement at three setting and etching intervals and compared these bonds to the shear strength of the material itself. Bonded cylinders were created and then sheared using the Instron Universal Testing Machine. Analysis of bond values of glass ionomer added to glass ionomer indicate bond variability and low cohesive bond strength of the material. Bond values of unbonded glass-ionomer material indicate that the material itself is stronger than bonds established between bonded samples.

The enhancement of memory in the first year.

Eleven infants were seen longitudinally at one month intervals from six through 11 months of age and administered tasks of recognition memory. The results revealed that the ability to retrieve a memory of an initially unfamiliar event that occurred more than five seconds earlier may be fragile until the child is about 10 months of age.
