Table 4.

Change in elastic modulus (E) of completely demineralized dentin specimens after the application of different concentrations of EDC and 10% glutaraldehyde (GA) for 30 s or 60 s.

Dentin treatment	Application time

	30 s	Statistical comparison	60 s
Water	0 (−16.4–20.7)^*^b	ns	0 (−13.6–48.1)^b
0.5 M EDC	−16.4 (−33.1–0.7)^b	ns	−11.1 (−3.2–21.5)^b
1 M EDC	−10.3 (−31.4–22.1)^b	^**	41.2 (−32.7–52.5)^b
2 M EDC	1.0 (−23–22.1)^b	^**	34.2 (15.7–64.4)^b
10% GA	123.5 (94–200.6)^a	^**	265.8 (181.3–347.5)^a

Values are expressed as percentage change related to the control and represent median (25 percentile–75 percentile), n = 10.

^**

Indicates statistically significant difference between application times.

Within each application time (columns), groups identified by the same letter are not statistically different (Mann–Whitney, p > 0.05).
