Abstract
Objectives: The aim of the present study was to assess the relationship between the maxillary sinus floor and the maxillary posterior teeth root tips using dental cone-beam CT. Methods: A total of 170 right and left maxillary sinus regions of 85 patients taken using Planmeca Proface CBCT machine (53 male and 32 female) were examined using cone-beam CT. Images were analyzed by an oral and maxillofacial radiologist. Perpendicular lines were drawn on the cross-sectional images between the deepest point of the maxillary sinus floor and the root tips of the maxillary first and second premolars and first, second and third molars, and the distances were measured using built-in measurement tools. Means, standard deviations and minimum and maximum values were calculated for all right and left premolars and molars. T-tests were used to compare measurements between left and right sides and between female and male patients. Results: The distance between sinus floor and root tip was longest for the first premolar on both the right left side. Shortest for the third molar mesiobucccal root tip for right and distobuccal root for left side. No statistically significant differences were found between the right and left side measurements or between female and male patients (P>.05). Conclusion: Knowledge of the anatomical relationship between the maxillary sinus floor and the maxillary posterior teeth root tips is imperative for the preoperative treatment planning and to avoid complications while treating maxillary posterior teeth.
