Radiographical approach to jaw lesions (original) (raw)
Application of Tomographic Methods in the Diagnosis of Pathological Changes of the Jaw
2011
The aim of this study was to evaluate the frequency of specific diagnostic methods used for diagnosis of oral pathologies. The sample consisted of 198 patients (98 man and 100 women) with formulated diagnosis, confirmed postoperatively by histopathological verification. In 74.7% of subjects only X-ray diagnostic examination was used. Both X-ray and computed tomography (CT) examinations were used in 18.7% of subjects. Magnetic resonance imaging (MRI) wasn't performed in any subject. In 6.6% of subjects neither X-ray nor CT was performed. The study reported on statistically significant differences in the distribution of specific diagnostic methods according to age groups (p=0.026). Also, there was statistically significant differences in the distribution of diagnostic methods according to diagnostic groups (p=0.053). In the group of 37 subjects, in whom both X-ray and computed tomography were used, the majority had carcinomas, followed by fractures and inflammatory cysts.
Jaw lesions associated with impacted tooth: A radiographic diagnostic guide
Imaging Science in Dentistry, 2016
This review article aimed to introduce a category of jaw lesions associated with impacted tooth. General search engines and specialized databases such as Google Scholar, PubMed, PubMed Central, MedLine Plus, Science Direct, Scopus, and well-recognized textbooks were used to find relevant studies using keywords such as "jaw lesion", "jaw disease", "impacted tooth", and "unerupted tooth". More than 250 articles were found, of which approximately 80 were broadly relevant to the topic. We ultimately included 47 articles that were closely related to the topic of interest. When the relevant data were compiled, the following 10 lesions were identified as having a relationship with impacted tooth: dentigerous cysts, calcifying odontogenic cysts, unicystic (mural) ameloblastomas, ameloblastomas, ameloblastic fibromas, adenomatoid odontogenic tumors, keratocystic odontogenic tumors, calcifying epithelial odontogenic tumors, ameloblastic fibro-odontomas, and odontomas. When clinicians encounter a lesion associated with an impacted tooth, they should first consider these entities in the differential diagnosis. This will help dental practitioners make more accurate diagnoses and develop better treatment plans based on patients' radiographs.
Comparison of the Role of Conventional Radiograph with Dentascan in Evaluation of Jaw Tumours
IP Innovative Publication Pvt. Ltd., 2017
Introduction: High cost, high patient dose and limited availability make CT imaging modality unsuitable for routine dentistry. Owing to the above points the present study was planned with the aim to compare the findings of Radiographs and Dental CT & compare the efficacy of dental CT with dental radiography in studying jaw tumours. Materials and Method: Patients with provisional diagnosis of jaw lesions were included in the study. All the included patients were planned to undergo Conventional radiograph and Dental CT. Once the investigations were done the findings of both the procedures were compared and evaluated with the help of an expert. Total of 40 patients were included in the study. Results: On radiographic evaluation 4 cases showed root resorption that was confirmed by CT evaluation. A kappa value of 50% with p value 0.03 indicates there is fair agreement between conventional radiograph and CT in relation to the adjacent tooth. Discussion and Conclusion: Dental CT at every step has proved to be better than dental radiographs for jaw lesion because it clearly depicts the extent of the lesions. There is no requirement of magnification, superimposition of anatomical structures and geometric distortion. More over dental CT also reduces the artefact from dental fillings.
Radiolucent rim as a possible diagnostic aid for differentiating jaw lesions
Imaging Science in Dentistry, 2015
In this study, we formulate a new proposal that complements previous classifications in order to assist dental practitioners in performing a differential diagnosis based on patients' radiographs. We used general search engines and specialized databases such as Google Scholar, PubMed, PubMed Central, MedLine Plus, Science Direct, Scopus, and wellrecognized textbooks to find relevant studies by using keywords such as "jaw disease," "jaw lesions," "radiolucent rim," "radiolucent border," and "radiolucent halo." More than 200 articles were found, of which 70 were broadly relevant to the topic. We ultimately included 50 articles that were closely related to the topic of interest. When the relevant data were compiled, the following eight lesions were identified as having a radiolucent rim: periapical cemento-osseous dysplasia, focal cemento-osseous dysplasia, florid cemento-osseous dysplasia, cementoossifying fibroma, osteoid osteoma, osteoblastoma, odontoma, and cementoblastoma. We propose a novel subcategory, jaw lesions with a radiolucent rim, which includes eight entities. The implementation of this new category can help improve the diagnoses that dental practitioners make based on patients' radiographs.
Tumors and tumor-like lesions of the jaw: radiolucent lesions
JBR-BTR : organe de la Société royale belge de radiologie (SRBR) = orgaan van de Koninklijke Belgische Vereniging voor Radiologie (KBVR)
Radiolucent lesions within the jaws represent a whole variety of lesions. Generally, they can be classified into two categories. The first category comprises well circumscribed lesions, either unilocular, multilobular or multilocular. They may be further subdivided into odontogenic or nonodontogenic lesions. The key feature that distinguishes these two subgroups is the relationship with the underlying dentition. Poorly circumscribed radiolucent lesions are the second category and consist of acute infectious disease and primary or metastatic malignancies. Although many of these lesions may present with non-specific imaging characteristics, careful analysis of a combination of imaging parameters may suggest a presumptive diagnosis. This article discusses the imaging features on different imaging techniques that may be useful in the characterization of these lesions.
A Clinicopathological Study of Jaw Lesions at a Tertiary Care Centre
Journal of Evidence Based Medicine and Healthcare, 2016
BACKGROUND Jaw bones are exceptional developmentally in having embryonal neuroectodermal cells on one hand and tooth germs on other. They cause destruction of the jaw bones and pose diagnostic challenge. MATERIAL AND METHODS Patients attending Oral and Maxillofacial Surgery Department at Osmania General Hospital during the period January 2013-May 2016 presenting with complaints of gradually progressive of jaw swelling, toothache and with radiological evaluation showing osteolytic, sclerotic, and cystic change were subjected to surgical excision. Representative tissue samples were processed routinely and stained by haematoxylin and eosin. RESULTS A total of 55 cases of lesions involving jaw bones were studied out of which 21 cases occurred in females and 34 cases in males. 47 lesions were encountered in mandible and 7 lesions in maxilla. A single case of firm-to-hard submandibular swelling was also included in the study. The lesions were categorised into cysts, odontogenic tumours, reactive bone lesions, giant cell lesions, and primary bone tumours. Ameloblastoma was the most common odontogenic tumour type, 15/55; one ameloblastoma case was recurrent followed by radicular cyst 7/55 and dentigerous cyst accounting for six cases and variety of other lesions. CONCLUSION A whole gamut of lesions occurred in the jaws presented with a considerable overlap in clinical, histological, and radiological features. The present study revealed mostly cystic and benign neoplastic lesions.
Evaluation of Radiopaque Jaw Lesions in a Turkish Population: A Retrospective Study
Hamidiye Medical Journal, 2022
Background: Radiopaque lesions are frequently found in the periapical region. The diagnosis and treatment of these lesions can be challenging to the dentist. The present study presents the similar radiographic features of the lesions to help the clinician narrow the differential diagnosis and to aid in treatment planning. This study aims to evaluate the frequency and distribution of radiopaque lesions in a Turkish population.
Clinical oral investigations, 2017
We assessed whether ultrasonography (US) can be used in combination with cone beam computed tomography (CBCT) to image intraosseous jaw lesions. Using CBCT and US, we evaluated 123 lytic intraosseous jaw lesions diagnosed in 121 patients with guidance from the CBCT findings. The lesions were classified into two groups based on histopathological evaluation: (1) cysts and (2) tumors and tumor-like lesions. US and histopathological findings on the lesions of the two groups and their relationships with each other were also assessed. Results are reported as means ± standard errors, and p < 0.001 was accepted as indicating statistical significance. In total, 123 lesions were evaluated; 74 (60.2%) were cysts and 49 (39.8%) were tumors or tumor-like lesions. The CBCT and US findings were compatible as far as dimensional measurements of the lesions in the three planes (p < 0.001). The US and histopathological findings on the content of the lesions correlated (p < 0.001). CBCT provid...
Application of CT for the Study of Pathology of the Jaws
Computed Tomography - Special Applications, 2011
Computed tomography (CT) scanning is very useful in identifying and evaluating the location, size, and suspected pathological diagnosis of lesions such as cysts, tumors, and infections. At the same time, it aids in the elucidation of bone and surrounding soft tissue invasion of lesions with high resolution. 1, 2 In the maxilla and mandible, teeth are included and the CT capacity there can distinguished a foreign body of only 30 µm. Precise size and location are needed in the evaluation of lesions in the maxilla and mandible based on a high resolution in addition to the suspected pathological diagnosis based on CT findings. Therefore, multi-detector CT (MDCT) scanning is commonly applied for various kinds of lesions in the maxilla and mandible because of its precision and diagnostic accuracy. Multidetector CT scanning provides rapid acquisition of numerous thin axial images and more accurate reconstruction images. Multi-detector CT scanning provides accurate information about the height, width, and three-dimensional (3D) evaluation of the maxilla and mandible, as well as detailed information about the location of normal anatomical structures, such as the mandibular canal, mental foramen, mandibular foramen, incisive foramen, and maxillary sinus. In addition, the relationship between lesions and anatomical landmarks, including cortical margins and roots of teeth, can be established. These images are also excellent because MDCT eliminates streak artifacts from dental restorations that degrade direct coronal CT scans. With MDCT, axial images are used to reformat the cross-sectional images, projecting the artifact along the crowns of the teeth rather than over the bone that is the region of interest. 3 At the same time, CT readings of lesions in the maxilla and mandible measured by MDCT can reflect the nature and inclusion within lesions, from which
