The influence of secondary reconstruction slice thickness on NewTom 3G cone beam computed tomography–based radiological interpretation of sheep mandibular condyle fractures

Objective:The aim of this study is to evaluate the effect of slice thickness on the visibility of inferior alveolar canal (IAC) in cone-beam computed tomography (CBCT) images.Materials and Methods:CBCT images of thirty patients (15 male and 15 female) with an age range between 40–50 years old were used. Cross-sectional images were obtained with 0.5, 1, and 2 mm slice thickness and 2 mm interval. Two oral radiologists with at least 5 years' of experience observed all of the 90 images and rated the images based on the visibility of IAC in a 4-score classification (highly visible, visible, nearly visible, nearly invisible). Friedman test was used for the comparison of visibility of IAC in different slice thicknesses. To do the above test, the average of the scores of two examiners was calculated. A P. value below 0.05 was considered significant.Results:Visibility of IAC in different slice thicknesses of both raters showed no significant difference (P = 0.20).Conclusion:Within the limitations of this study the slice thickness has no effect on visibility of IAC in cross-sectional images. Future studies on other multiplanar images are recommended.

“…Several studies have supported the use of CT for the management of trauma to the maxillofacial skeleton . However, application of medical CT in dentistry has certain limitations such as high radiation dose, degradation of the image quality by metallic artifacts, high cost, limited availability of the procedure and large, dedicated space requirements with lower temperature . In addition, the anisotropic image voxels result in lower accuracy of reconstructed images compared with the original scans .…”

“…Currently, several tomographic radiological devices allow the imaging of bone in several plains and circumvent the problems arising from inadequate projections of the skull base on plain radiographs (9, 29). However, thin sections of the examination region must be made with tomography, because otherwise some fractures will not be displayed (30). Indeed, lack of fracture displacement is the single most important factor in missed fractures with all X-ray modalities (9).…”

Aim: The report is about diagnosis, therapy, and follow-up of a 15-year old boy, who experienced facial swelling and impaired mouth opening after a sport accident. Case Report: Diagnosis of mandibular damage was delayed due to inadequate clinical investigation and radiography after trauma and only became clear after a parotid swelling occurred sometime later resulting from the dissolution of the upper part of the articular process. Follow-up control over a period of three years showed a partial restoration of the articular process but some inhibition of mouth opening combined with slight deviation of the mandible to the affected side remained over the years. Conclusion: This report reminds us that parotid swelling can be the result of mandibular trauma without a recent history of physical injury to this region. Therefore, the basic standards of radiologic diagnosis should be maintained and the limited restoring capacity of the condylar process in adolescence should be acknowledged.
