SD – standard deviation; SCT – single cone technique; CLCT – cold lateral compaction technique; CWT – continuous wave technique; F – variation between samples; P – probability. Level of significance: NS (non-significant)=P≥0.05; * Significant=P All differences made at the probability (p) value of ≤0.05. |
