The Relationship

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 87 right and 89 left maxillary sinus regions from 92 patients were examined using dental cone-beam CT. Images were analyzed by a specialist in oral and maxillofacial radiology. 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 root tip and shortest for the second molar buccodistal root tip for both right and left sides. No statistically significant differences were found between the right and left side measurements or between female and male patients (P>.05).Conclusions: Knowledge of the anatomical relationship between the maxillary sinus floor and the maxillary posterior teeth root tips is important for the preoperative treatment planning of maxillary posterior teeth.

The Relationship

ABSTRACT Aim This study was conducted to assess the vertical and horizontal relationship between the maxillary sinus floor and maxillary posterior teeth roots using cone beam computed tomography. Materials and methods In this cross-sectional study, the CBCT images presented in the radiology department of Hamadan dental school was used. From 450 observed CBCT, 340 of them did not have the inclusion criteria of the study and ultimately 110 CBCT were selected. Totally 214 first premolars, 217-second premolars, 220 first molars and 220-second molars were included. For evaluating the relationship between the maxillary sinus floor and the posterior maxillary teeth, the classification implemented in the study of Jung in 2009 was used. The relation was evaluated by two radiologists twice with a 2-week time interval. Results One hundred and ten patients with a mean age of 31.06 ± 9.7 years were assessed. Type 0 relationship (the maxillary sinus floor is located above the root tip) was most frequently observed with the first and second premolars. The most common type observed in the first and second molars was type 3 (apical protrusion is seen over the maxillary sinus floor). The relation between different types and gender was statistically meaningful, while no statistically significant difference was found between the right and left side assessments. Conclusion This study showed that although most of the teeth did not have contact with the sinus floor, but the more posterior the maxillary teeth, the more probability for root protruding into the maxillary sinus. It also confirmed that protrusion of teeth roots into the maxillary sinus is more common in male than female. Clinical significance Knowing the anatomical relation between the posterior teeth and the maxillary sinus, help the clinician in preoperative treatment planning of the posterior maxillary teeth and avoid problems that may occur during dental practice.

The Relationship

Background: Having knowledge about the anatomical and pathological relationship between the maxillary posterior root tip and the maxillary sinus floor is very significant for preoperative treatment planning. Aims and Objectives: The purpose of the present study was to compare the accuracy of original panoramic radiographs and digital panoramic images over cone beam computed tomography (CBCT) images in evaluating the relationship between the maxillary posterior teeth and the maxillary sinus floor, and to verify the accuracy of the signs of the relationship between the roots of the maxillary posterior teeth and maxillary sinus on the panoramic radiographs over CBCT images. Materials and Methods: From 106 subjects (47 males and 59 females; mean age = 39 years; range = 18-67 years) referred to our university, a pair of panoramic and CBCT images was selected for further analysis. The relationship between the maxillary posterior teeth, the maxillary sinus, and panoramic radiography signs (root projection into the sinus, interruption of the maxillary sinus floor cortex, absence of lamina dura, darkening of the root apex, and curvature of the sinus floor on the root apex) associated with the protrusion of root apexes into the sinus was evaluated. Results: The P values of the data obtained from the original and invert enhanced panoramic images were .53 and .52, respectively, and there was no statistically significant difference in the accuracy of the 2 methods ( P > .05). Conclusion: The root projection into the sinus is an indicative sign of root protrusion into the sinus on CBCT.
