Notes:
Δt, temperature change in pulp chamber; SD, Standard deviation; CCs, coloured compomers.
p ≤ 0.05 means statistically significant difference. The values indicated by different superscript small letters show statistical significant difference. The values indicated by * and ** are statistical significantly different from each other.
