Group	MP1	MP2	MP3	MP4	MP5
Occlusion 30 min	2108 (100)	384 (18.2)	1351 (64.1)	656 (31.1)	495 (23.5)
Occlusion 40 min	841 (100)	0 (0)	0 (0)	0 (0)	74 (8.8)
NaCl (45 min)	2245 (100)	144 (6.4)	318 (14.2)	267 (11.9)	64 (2.9)
Na₂S (45 min)	1148 (100)	23 (2)	25 (2.2)	10 (0.9)	6 (0.5)

All data are mean in microvolt and percentage of residual MEP compared to baseline (in brackets). Sodium chloride (NaCl), n = 4. Sodium sulfide (Na₂S) n = 4. The data of the two groups with 30 min (n = 3) and 40 min (n = 2) occlusion time were obtained in preliminary experiments as described above. MP measuring point
