“…6 The panoramic radiography is the most common diagnostic aid used to assess the proximity between maxillary posterior roots and the maxillary sinus, but assessments of relationship between the upper dental roots and the maxillary sinus showed that panoramic radiography and CT scans differ significantly. 4,10,11,13 To our knowledge, however, the present work is the first to propose panoramic radiographic signs that could alert the surgeon to possible root protrusions into the maxillary sinus. Our understanding is that despite the problems of image distortion and the lack of sharpness, panoramic radiography is nevertheless useful in most routine clinical situations and is an invaluable tool for determining the need for pre-operative CT scan, as suggested for mandibular third molars.…”

“…Likewise, agreement was high when roots were protruding into the maxillary sinus; comparable results were reported elsewhere for first molars, second molars and second premolars (84%, 63% and 31%, respectively). 11 By contrast, Sharan and Madjar 10 found agreement to be low when the roots protruded into the maxillary sinus. Explanations for such difference may reside in the fact that the latter study evaluated each root individually (in multirooted teeth) and used a different scoring system with four components to indicate the protrusion of roots instead of the three used here.…”

“…The relationship between the maxillary posterior teeth and the maxillary sinus floor was evaluated according to the criteria established by Shahbazian et al 11 In brief, CBCT and panoramic radiographic images of each tooth, whether single or multirooted, were attributed a score as follows:…”

“…The most commonly used approach is the panoramic radiography, which allows visualization of several anatomical features at low cost and with a relatively low radiation dose. 10,11 However, the superimposition of anatomical structures, unwanted horizontal and vertical magnification and the absence of cross-sectional information 10 are some of the disadvantages of this technique. 10 In general, panoramic radiography is an unreliable method for determining the relationship between upper posterior teeth and the maxillary sinus.…”

Objectives: Given the limitations of panoramic radiography for assessing topographic relationship of maxillary teeth with sinus floor, the purpose of this study was to assess signs on panoramic radiography that could predict root protrusion into the sinus. Methods: A total of 46 individuals (330 maxillary posterior teeth) who underwent panoramic radiography and CBCT were enrolled. The relationship between the posterior teeth and the maxillary sinus and panoramic radiography signs (projection of the root apices, interruption of the maxillary sinus floor, lamina dura, darkening in the root apices, and superiorly curving sinus floor enveloping the associated tooth root) associated with protrusion of root apices into the sinus were evaluated. Results: There were differences between the imaging modalities about the positioning of the root apices regarding the sinus (p , 0.05). Only the projecting of the root apices and the interruption of the sinus floor on panoramic radiography were predictors for the root protrusion (p , 0.05). No significant association was observed for the other panoramic radiography signs (p . 0.05). Conclusions: The root projection into the sinus and the interruption of the sinus floor are indicative signs of root protrusion into the sinus on CBCT.

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.

Objectives: The present study aims to describe the relationship between upper first molar roots and maxillary sinus, for the first time with a truly three-dimensional approach.Methods: From a retrospective cone-beam computed tomography (CBCT) sample of the upper jaw, a total of 105 upper first molars in contact with maxillary sinus from 74 patients (male 24, female 50, mean age 42) were included in the present study.Segmentation of the upper first molar and maxillary sinus in CBCT was performed utilizing a semiautomatic livewire segmentation tool in MeVisLab v.3.1. The segmentations were analyzed in 3-matic Medical 20.0 for root volume and the contact area between upper first molar roots and maxillary sinus. Analysis of variance test was applied to detect statistically significant differences between the roots. Results:The palatal root had the largest contact area with maxillary sinus 27.8 ± 21.4 mm 2 (20% of the root area) followed by the mesiobuccal 20.5 ± 17.9 mm 2 (17% of the root area) and distobuccal root 13.7 ± 12 mm 2 (14% of the root area). A significant difference in the contact area of the different roots of the upper first molar was seen.Conclusions: This study showed that 70% of the upper first molars were in contact with the maxillary sinus. The palatal root had on average a fifth of its root surface in contact with the sinus, while for mesiobuccal this was a sixth of its root surface and distobuccal roots this was somewhat less. The true 3D relationship could help to better understand maxillary anatomy in relation to occurring pathologies and treatment planning in this area.

Comparative assessment of panoramic radiography and CBCT imaging for radiodiagnostics in the posterior maxilla

Abstract: CBCT imaging can be a valuable adjunct in radioanatomical and radiodiagnostic observations in the posterior maxilla. It may better visualize maxillary sinus involvement for posterior upper teeth than panoramic radiography.
