MTA-like cements vs. CH cements | 0.41 [0.23, 0.73] ** | HIGH | 0.59 [0.45, 0.78] *** | HIGH |
MTA-like cements vs. ALL CH-based materials (CH cements + powder) | 0.66 [0.47, 0.92] * | HIGH | 0.80 [0.62, 1.03] | HIGH |
CH cements vs. CH powder | Not available | Not available | 3.23 [2.00, 5.20] *** | MODERATE a |

1 Only one study available for direct comparison between MTA-like cements vs. CH powder [52]. 2 Only 1 study available for direct comparison between calcium-silicate cements vs. CH cements [107]. 3 Only two studies available for direct comparison between Biodentine vs. Pro-Root MTA [104,106]. 4 The direct comparison was strong enough (13 studies). a Level of the evidence downgraded one level due to high risk of bias in all studies. b Level of the evidence downgraded one level due to high risk of bias in all studies and imprecision. * The result is statistically significant (p < 0.05); ** The result is statistically significant ( p <0.01); *** The result is statistically significant (p < 0.001 or lower).
