    AIM: The study aims to determine the frequency of positioning errors, record the number of diagnostically inappropriate images, and assess the quality of panoramic radiographs.

    MATERIALS AND METHODS: In this study, a total of 2629 patients for whom orthopantomogram were selected out of 3900 new patients between August 2020 and June 2021. The positioning errors of the radiographs were evaluated and categorized into ten groups. The quality of the radiographs is further assessed as "Excellent," "Diagnostically Acceptable," and "Diagnostically Unacceptable."

    RESULTS: Out of the total radiographs, 32.8% had no errors, and 77.2% of the radiographs had one or more positioning errors. The radiographs were analyzed in detail, and the errors found in the panoramic radiographs were recorded. The most common positioning error observed in the radiograph was error 8, failure to place the tongue close to the palate.

    CONCLUSION: The results and evaluation inferred that attention to patient positioning and focusing on reducing diagnostically indecent images could improve the quality of panoramic radiographs. Proper instructions to the patient, patient preparation, appropriate positioning of the patient, and the technician's skill plays a vital role in reducing diagnostic errors in Panoramic Radiography.

    This study evaluated the validity of panoramic radiography and cone beam computed tomography (CBCT) in the assessment of mandibular canal and impacted third molar. In this descriptive-analytical study, 58 mandibular third molars from 42 patients who showed a close relationship between impacted third molar and canal on panoramic radiographs were selected. They were then classified into seven radiographic markers in panoramic radiographs (superimposition, darkening of the root, interruption of the white lines, root narrowing, canal diversion, canal narrowing, and also closed distance in OPG <1mm). The groups of markers were further assessed with CBCT to see presence or absence of contact. The three most common markers seen in panoramic images are superimposition, interruption of white line and root darkening. In CBCT, superimposition marker always presented higher frequency of contact with canal compared to non-contact group. There are 31% of teeth presented with interruption of white lines and there are 29.3% of teeth presented with superimposition. About 55.6% and 35.3% of the impacted mandibular third molars which indicated interruption of white lines and superimposition also indicated contact in the CBCT respectively. Presence or absence of radiological sign in panoramic radiography was not properly predict a close relationship with third molar and it is suggested that in case of tooth-canal overlapping, the patient should be referred for CBCT assessment.
