Radiological findings in panoramic radiographs of Iranian edentulous patients

Abstract

Objectives. The early diagnosis of probable lesions in edentulous patients is essential, as complications can include irritated tissue and recurrent infectious abscesses. This study determined the prevalence of impacted teeth, retained roots, condensing osteitis, and upper and lower jaw atrophy in panoramic radiographs of edentulous patients. Methods. This descriptive study examined panoramic radiographs from the records of the Oral Maxillofacial Radiology . The sampling method was simple, and 447 samples were included in the study. Each radiograph was studied for impacted teeth, retained roots, condensing osteitis, maxillary sinus migration, and change in position of the mental foramen in relation to the apex of the residual ridge. The data were analyzed using the χ-squared test. Results.Of the 447 radiographs, 305 (68.2%) showed migrated maxillary sinuses, 220 (49%) showed a change in the position of the mental foramen in relation to the apex of the remaining alveolar ridge, 150 (33%) showed condensing osteitis, 145 (32.4%) showed retained roots, and 28 (6.3%) showed impacted teeth. Conclusion. The results of this study suggest that panoramic radiography is critical before making dentures for patients.

Evaluation of dental panoramic radiographic findings in edentulous jaws: A retrospective study of 743 patients "Radiographic features in edentulous jaws"

“…3 4 Abnormalities such as root fragments, impacted teeth, neoplasms, and foreign bodies are often overlooked when they do not cause symptoms or clinical signs. 5 …”

“…2 4 6 7 However, only a few studies have documented the rate of these radiographic findings requiring treatment. 4 5 6 7 Consequently, the aim of this study was to report the frequency of significant radiographic findings, to discuss utility of panoramic radiographs and to obtain the rate of the conditions which treatment is necessary before conventional or implant supported prosthetic rehabilitation in edentulous patients.…”

Intraosseousenign Lesions of the Jaws: A Radiographic Study

“…Given the relatively high incidence of maxillary/mandibular cysts and tumors ( 1 ), dentists may have to conduct full radiographic investigations once a preliminary diagnosis is made, in order to determine the extent and characteristics of the lesion that may sometimes be specific enough to make a fairly accurate early diagnosis of a particular tumor ( 2 ). In addition, radiographs can occasionally lead to the accidental discovery of lesions with no apparent pertinence to the patient's chief complaint, which is of substantial benefit to both the patient and the physician, as early diagnosis often obviates the need for aggressive therapy ( 3 ).…”

“…The latter, for instance, provides an overall view of the jaws and teeth structure that cannot normally be achieved by using other visual diagnostic modes. The former, however, fails to capture dento-alveolar lesions ( 1 ); whereas, it is well-known for high resolution images owing to direct exposure films, making it ideal for detecting fine details ( 2 ). A dentist can be the first health caregiver to come across a variety of lesions; namely cystic, tumoral lesions in the jaws and a deeper insight and better knowledge of radiological clues can contribute enormously to a precise diagnosis.…”

Common Errors on Conventional and Digital Panoramic Radiographs

“…Panoramic radiography is popular diagnostic tool and is used alone or along with other radiographic techniques (2). At present, it is widely used in dentistry as a useful tool for the diagnosis and treatment planning (3). Panoramic radiographs are clinically useful to diagnose conditions that require a wide coverage of the jaws, including traumas, the position of third molars, extensive disease entities, identification of suspected large lesions, tooth development (especially in the mixed dentition period), residual teeth or roots (in edentulous patients), and congenital/developmental anomalies.…”
