Table 4.

MTBS of resin–dentin bonds with EGCG, nHAp@MSN, and EGCG@nHAp@MSN preconditioner under simulated pulp pressure. Values are mean ± SD in MPa, n = 10 beams. Different numerical superscripts in one row represent the significant difference (P < 0.05); different letter superscripts in one column represent significant differences (P < 0.05).
