Objective: The aim was to identify the distance between the apices of maxillary posterior teeth and maxillary sinus (MS) floor as well as the thickness of the bone between the root and the alveolar cortical plate. METHODS: The cone-beam computed tomography scans of 74 patients were evaluated retrospec- tively. Topographic measurements of the surrounding bone at the apex of all premolar and molar maxillary teeth were performed in 2 different planes (vertical and horizontal). A 1-way analysis of variance was used to determine the differences in linear measurements between each root for all tooth types and genders. Results: The mean vertical distance to the MS floor was significantly high for first premolar roots and the lowest mean vertical distance was measured for mesio-buccal roots of second molars (P < 0.05). In contrast, the lowest buccal bone thickness was found for the first premolar, whereas the highest buccal thickness was measured for the mesiobuccal roots of the second molars (P < .05). When gender groups were evaluated separately, it was found that the vertical distance between the apices of second premolar teeth and the MS floor was significantly higher in females (P < .05). Moreover, the mesiobuccal and palatal horizontal measurements of second molars were higher in females (P < .05). Conclusion: It is important to have knowledge about the linear measurements and morphologi- cal features of the maxillary alveolar bone in order to carry out successfull dental practices The obtained results were expected to be beneficial for clinicians to reduce the complication, espe- cially in dental procedures involving maxillary molar region.
