Filter by:Introduction: Panoramic radiography quality can be impaired by some errors such as positioning errors. Palatoglossal air space shadow error is one of the most common positioning errors and it's due to the tongue not sticking to the roof of the palate. Techniques used to deal with this error might help prevent unnecessary radiation to patients and save them time and money. The study aimed to investigate to investigate the effects of using celluloid matrix and edible tapes (fruit leather and chewing gum) on reducing the palatoglossal air space shadow error in panoramic imaging Methods: In our study, 270 patients referred to the Department of Radiology were randomised into three groups: a control group, a celluloid matrix group, and an edible tapes group. Before panoramic imaging, all patients were instructed to adhere their tongues to the roof of their mouths, with the distinction that for the celluloid matrix and edible tapes groups, patients were asked to place celluloid tapes, fruit leathers, or chewing gums on their tongues before doing so. The routine imaging process was then performed, and the results were compared across groups to evaluate the incidence of palatoglossal air space shadow error. Results: *** Conclusion: ***
The aim of the study is to evaluate the relationship between submandibular fossa depth and gonial angle measurements in cone beam computed tomography examinations in terms of dental implant applications. Cone-beam computed tomography images of 51 dry human mandibles were included in the study.
Research questions: 1. Will the panoramic images derived from cone beam CT data give better diagnostic ability than conventional panoramic radiographs? 2. Will 3D cephalometric analysis offer the orthodontists and surgeons better information for treatment planning? 3. Will the 3D cephalometric analysis give more accurate treatment plan and better treatment outcome? General hypothesis and special aims Overall aims: - To compare 2D versus 3D cephalometric analysis: treatment planning and therapeutic outcome. - To determine the accuracy and diagnostic ability and usability of the 3D cephalometric analysis. - To evaluate the diagnostic ability and usability of the panoramic image derived from cone beam CT data as compared to 2D panoramic images. - To evaluate the value of the cone beam CT data in cephalometric analysing process for orthodontic and maxillofacial surgery treatment. Hypotheses: 1. The availability of the 3D cephalometric analysis influences the orthodontic and maxillofacial treatment plan and decision, and might change the treatment outcome. 2. Panoramic images derived from cone beam CT data may provide equal information for diagnosis as conventional panoramic images. 3. Cone beam CT will be able to replace "classic orthodontic imaging" being more time and dose efficient and having a beneficial effect on treatment outcome.
