Therefore, knowing that a thorough understanding of the anatomical correlation between maxillary sinus floor (MSF) and maxillary teeth is indispensable for the management of cases; this research was undertaken to evaluate the proximity of root apices of the maxillary posterior (RAMP) teeth to the MSF using cone-beam computed tomography (CBCT) among different age groups of the Indian population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>CBCT scans of 150 patients were obtained from the institute\u2019s database based on strict inclusion and exclusion criteria; such that an equal number of samples were obtained in the following three age groups: Group 1 \u2013 Young group (20\u201344 years), Group 2 \u2013 Middle age (45\u201359 years), Group 3 \u2013 Elderly (60\u201370 years). CBCT images were assessed in multiple cross-sections using Planmeca Romexis software to evaluate the vertical relationship between the RAMP teeth and the MSF.
