Table 3.

Percentage of total MMP inhibition in 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 (−26.0–11.3)^*^b	ns	−0.7 (–13.8–24.1)^c
0.5 M EDC	64.4 (60.0–72.8)^a	ns	58.6 (32.3–71.6)^ab
1 M EDC	48.9 (34.7–67.9)^a	^**	77.6 (65.9–80.6)^a
2 M EDC	64.4 (61.5–70.9)^a	^**	81.9 (73.3–85.3)^a
10% GA	65.3 (59.2–70.6)^a	ns	55.4 (49.1–59.1)^b

Values are expressed as percentage absorbance 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).
