Investigating the anatomical relationship between the maxillary molars and the sinus floor in a Chinese population using cone-beam computed tomography

摘要

Measurements of maxillary molars using CBCT cross-sectional images. The measurements include 1-the distance between the mesiobuccal root apex and the inferior wall of the MSF (DMBR), 2-the cortical thickness of the MSF closest to the mesiobuccal root apex (CTMBR), 3-the mucosa thickness of the MSF closest to the mesiobuccal root apex (MTMBR), 4-the distance between the distobuccal root apex and the inferior wall of the MSF (DDBR), 5-the cortical thickness of the MSF closest to the distobuccal root apex (CTDBR), 6-the mucosa thickness of the MSF closest to the distobuccal root apex (MTDBR), 7-the distance between the palatal root apex and the inferior wall of the MSF (DPR), 8-the cortical thickness of the MSF closest to the palatal root apex (CTPR), 9-the mucosa thickness of the MSF closest to the palatal root apex (MTPR), and 10-the angle between the buccal and palatal roots
