Table 2. Means and standard deviations of MH (GPa), Eit^* (GPa) and surface gloss (GU) of sound and eroded bovine dentin.

Groups	MH	Eit^*	Surface gloss
Bovine dentin with citric acid protocol	0.7±0.04^B	20.5±1.2^B	60.7±2.8^B
Bovine dentin with HCl-pepsin protocol	1.1±0.04^A	28.3±0.9^A	60.3±1.7^B
Sound bovine dentin	1.2±0.05^A	29.2±1.0^A	76.8±2.3^A

Different letters in columns indicate that values are significantly different from each other (p<0.05)
