Degradation effects of dietary solvents on microhardness and inorganic elements of computer-aided design/computer-aided manufacturing dental composites

Table 4 Comparison of mean KHN values between materials based on individual dietary solvent^a

Dietary solvents	Differences between composite materials
Air (control)	VE > LU > CM,CS,FZ
Distilled water	VE > LU > CS, FZ; VE > CM
0.02 N Citric acid	VE > LU,CM,CS,FZ; LU,CM > FZ; LU > CS
0.02 N Lactic acid	VE > LU,CM,CS > FZ; LU > CS
50% Ethanol-water	VE > LU > CM,CS,FZ

Abbreviations: CM: Shofu Ceramage; CS: Cerasmart; FZ: Filtek Z350 XT; LU: Lava Ultimate; VE: Vita Enamic; KHN: Knoop hardness
^a Results of one-way analysis of variance and post hoc test (p < 0.05);
