Comparison of anterior and posterior trabecular bone microstructure of human mandible using cone-beam CT and micro CT

Table 2 Intra-regional comparison of trabecular microstructure parameters using CBCT and µCT. The measurements of trabecular number (Tb.N), trabecular thickness (Tb.Th) and trabecular separation (Tb.Sp) of either anterior (n = 6) or posterior (n = 14) regions were compared using the independent sample t-test
