Table 2.

Comparison of SBS between the groups according to the three different factors assessed: conditioning methods, bonding agents and composite types.

Groups		N	Mean (Mpa)	Std Dev	p-Value
Conditioning methods	HFA	40	15.82 ^a	4.72	<0.0001 ***
	AA	40	14.91 ^a	5.38
	PhA	40	5.22 ^b	4.03
Bonding agent type	Assure universal bond	60	14.04	6.04	0.001 **
Bonding agent type	Single bond universal	60	9.93	6.80	0.001 **
Composite type	Filtek Z350	60	13.79	7.47	0.003 **
Composite type	Filtek Z350 supreme Ultra flowable	60	10.18	5.38	0.003 **

Significance levels: ** p < 0.01, *** p < 0.001. Values with different superscript letters indicate significant differences between the different conditioning methods (a > b).
