“…First molars in contact with MS (Table 2) were in the present study considerably more prevalent than in an earlier study that measured the number of 1st molars protruding into the MS (Nino- Barrera et al, 2018). Although, it is important to notice that the way of grouping the measurements differ from current studies.…”

Objectives: To describe the relationship between maxillary sinus (MS) and upper teeth based on cone beam computed tomographic scans (CBCT). Materials and methods:Based on CBCT maxillary imaging data of 147 patients, distance between MS and apices of canines and posterior maxillary teeth were assessed.Distances between tooth roots and sinus were classified into three groups: distant (>2 mm), close (<2 mm) or in contact with MS. Teeth with apical lesions and uncommon root configurations were excluded.Results: In total, 1075 teeth of maxillary canines, upper premolars and upper molars were included in this study. Teeth most often in contact with MS were the second (89%) and first (81%) maxillary molar without any significant difference (p = 0.19).Roots most often in contact with MS were the mesiobuccal and distobuccal root of the second molar (85% and 76%; p = <0.01) followed by the palatal root of the first molar (73%). A fifth of the upper canines are situated less than 2 mm from MS.Conclusions: More than four out of five upper molars (first and second) are in a close relationship to the MS. Knowledge of the anatomical relationship between posterior maxillary teeth and the MS is important for diagnosis and treatment in this area.

“…The present study includes protruding roots and roots that touch the MS in one group, while other studies separate them. The result of previous studies assessing molars roots in contact with MS; 20-63% for second upper molars, 25-84% for first upper molars (Kilic et al, 2010;Nino-Barrera et al, 2018;Shahbazian et al, 2014).…”

“…18,[23][24][25][26][27][28] Other studies reported that the palatal root of the first molar most frequently protruded into the sinus. 19,[29][30][31][32] Our results revealed that the type 3 (root protrusion into the sinus) configuration occurred most frequently in the mesiobuccal root of maxillary second molars (48.4%), while type 2 occurred most frequently in the palatal root of maxillary first molars (43.1%). Previous studies have reported that the palatal roots of second molars exhibited the lowest incidence of protrusion into the sinus.…”

“…Panoramic radiography is the main imaging technique used to evaluate the close relationship between the maxillary posterior roots and maxillary sinus; however, the assessment of the relationship between the upper teeth roots and maxillary sinus has shown that panoramic radiography and CBCT are significantly different techniques. 18,19 Despite image-distortion problems and lack of acutance, panoramic radiography has been reported to be useful in most routine clinical situations and an important tool in determining the need for preoperative CBCT scanning. 20,21…”

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.
