  1. Tooth position 16 represents the right first molar, 17 represents the right second molar, 26 represents left first molar, and 27 represents left second molar. CTMBR, cortical thickness of the MSF at the mesiobuccal root apex; CTMDR, cortical thickness of the MSF at the distobuccal root apex; CTPR, cortical thickness of the MSF at the palatal root apex. n teeth number; unit: mm; data are presented as the mean SD
