ABCSimilar superscript capital letters in the same column denote a significant difference among different materials within the same level on the same side (demineralized/remineralized; p < 0.05).
abcSimilar superscript lowercase letters in the same row denote a significant difference among different levels within the same material on the same side (demineralized/remineralized; p < 0.05).
$Non-significant difference between the demineralized and remineralized specimens for the same level in the same material.
