Mean retention forces (Mean) and standard deviations (SD) for the different material groups (DECBL = Denzir sandblasted; DECUNBL= un-sandblasted; PROCERA) and storage groups (AS = artificial saliva; Water) expressed in Newtons. The results are based on pooling the values for the two storage times.

Material	Storage	N	Mean ± SD
DECBL	AS	6	2184.2 ± 1313.8
DECBL	WATER	6	1283.3 ± 433.7
DECUNBL	AS	6	1716.3 ± 728.1
DECUNBL	WATER	6	2024.5 ± 663.3
PROCERA	AS	6	2045.0 ± 526.0
PROCERA	WATER	6	1286.0 ±383.6
