Mean surface dynamic microhardness and elastic modulus of different root repair materials after setting in various environmental conditions. Distinct superscript lower-case letters above each bar graph signify a statistically significant dissimilarity among the subgroups represented by the respective bar graph (P < 0.01), while those with equal letters mean no significant difference (P > 0.05). Abbreviations: ERRM Putty: EndoSequence Root Repair Material Putty; IRM: intermediate restorative material; iRoot FS: iRoot Fast Set Root Repair Material; WMTA: White mineral trioxide aggregate
