Mean retentive forces (Mean) and standard deviations (SD) of the different storage groups (AS = artificial saliva; Water) expressed in Newtons. The values generated by pooling the material group values and the two storage times.

Storage	Mean ± SD	N	Duncan Grouping
AS	1981.8 ± 886.4	18	A
WATER	1531.3 ± 597.3	18	A
