Thank you very much for your interesting presentation.

Q1 The adhesive force after 35 days was larger than that after 24 hours in D and E. What do you think about this reason?

Thank you for your question.

Generally, it is thought that mean adhesive force after 35days tends to be smaller than that after 24 hours because of resin expansion in the water. However, mean adhesive force after 35days is larger than that after 24 hours in D, E groups and the reverse result in A, B, C groups. This may be because the difficulties to measure the maximum attractive force. Standard Deviation is a little bit large copared to mean value as shown in Fig.6.
At any rate, there are no statistical differences (p<0.05) between 24h. group and 35d. group.
