Abstract: The maxillary sinus (antrum of Highmore) is the first of the paranasal sinuses to develop. These structures are usually fluid-filled at birth. The growth of these sinuses is biphasic with growth during years 0-3 and 7-12. During the later phase pneumatization spreads more inferiorly as the permanent teeth take their place. Pneumatization can be so extensive as to expose tooth roots with only a thin layer of soft tissue covering those. This study aimed to evaluate the relation of maxillary molars roots to maxillary sinus floor. For the right maxillary first molar and second molar and for the left maxillary first molar, the most common type was (type 3), and the least one was (type 1), for the left maxillary second molar, the most common type was (type 2), and the least one was (type1).
