Minimum inhibitory concentration among different paste combinations.*
| Variables† | Mean (SD) | Minimum | Maximum |
|---|---|---|---|
| Zinc oxide-Eugenol- ug/μl | 4.5 ± 3a | 1.9 | 7.8 |
| Calcium hydroxide - ug/μl | 4.5 ± 3a | 1.9 | 7.8 |
| Calcium hydroxide-zinc oxide (1-1) - ug/μl | 10.4 ± 4.5a | 7.8 | 15.6 |
| Calcium hydroxide-zinc oxide (3-1) - ug/μl | 5.2 ± 2.2a | 3.9 | 7.8 |
| Calcium hydroxide-zinc oxide (1-3) - ug/μl | 26 ± 9b | 15.6 | 31.2 |
| Calcium hydroxide-zinc oxide mixture (1:2) - ug/μl | 26 ± 9b | 15.6 | 31.2 |
| Calcium hydroxide-zinc oxide mixture (2:1) - ug/μl | 5.2 ± 2.2a | 3.9 | 7.8 |

Each test was repeated three consecutive times.
†
Cross comparison of minimum inhibitory concentration between pastes showed that calcium hydroxide-zinc oxide mixture (1:3) and calcium hydroxide-zinc oxide mixture (1:2) had a significantly higher minimum inhibitory concentration compared to all other pastes (p < 0.001). Superscript alphabets show a significant difference between that of the mentioned pastes.
