Influence of Polishing Methods on the Bonding Effectiveness and Durability of Different Resin Cements to Dentin

Table 3

Failure mode counts of all the specimens after microtensile test.

Resin cement	Polishing method	24-hour water storage			2-year water storage
		(a)	(b)	(c)	(a)	(b)	(c)
Etch-and-rinse	A	17	0	3	15	3	2
	B	19	0	1	16	2	2
Self-etch	A	18	1	1	18	1	1
	B	18	0	2	17	2	1
Self-adhesive	A	20	0	0	19	0	1
	B	18	0	2	18	0	2

Failure modes: (a) adhesive failure (failure within dentin/resin cements interface); (b) cohesive failure (failure solely within resin cements); (c) mixed failure (partially cohesive failure within resin cements with some adhesive failure).
