Apical periodontitis may be associated with odontogenic sinusitis in cases where the apex of the root is close to, or even within, the maxillary sinus. This study investigated the anatomical relationship between the cortical sinus floor and the root apices of maxillary molars in relation to age and gender. Two hundred cone-beam computed tomography exams (FOV 5 × 5 cm or 8 × 8 cm) were evaluated to determine the proximity of the roots of the molars to the maxillary sinus, according to age group and gender. The maxillary second molar is the tooth with the closest contact with the maxillary sinus, mainly the mesial–buccal root. In maxillary first molars, the palatal root is the nearest one and sometimes lies inside the sinus. Considering the age factor, in the elderly group, lower distances were found for all roots for the male group. In the elderly group, the only difference was found in the female distobuccal root of tooth 16, which was found to be shorter than the males (p < 0.05). In conclusion, the distance between the cortical bone of the maxillary sinus and the root apices varies considerably, and smaller distances were found in older females and for the upper second molar, especially the mesial–buccal root.
