Influence of Air Abrasion and Sonic Technique on Microtensile Bond Strength of One-Step Self-Etch Adhesive on Human Dentin

Table 2

Microtensile bond strength values in MPa obtained for the different experimental groups and number of adhesive and cohesive failures.

Experimental group	Mean/MPa	SD	A^*-failure	C^*-failure
Control	35.3	12.8	43	21
Air abrasion	35.8	13.5	66	18
Sonic	37.7	12.0	66	14

A^*: adhesive; C^*: cohesive.
