The relevance of clinical and radiographic features of jaw lesions: A prospective study
Brazilian Oral Research, 2016
The study was carried out in a Brazilian population and the aim was to describe the prevalence and the clinic-radiographical features of jaw lesions. In addition, a comparison between the main diagnosis hypothesis and final diagnosis was accessed. A prospective study which evaluated all patients with jaw lesions diagnosed in an Oral Diagnosis Center, between August 2013 and October 2014. A total of 450 patients were observed for the first time, and 130 had some type of jaw lesion. The mean age of the patients was 35.2 years ± 17.86. Among these, 71 were women (54.62%) and 87 were Caucasian (66.92%). The mandible was affected more frequently (71.43%) than the maxilla (28.57%). Swelling and pain were the most frequent clinical signs and symptoms and were observed in 60 (42.85%) and 38 (27.14%) cases, respectively. The panoramic x-ray was the main radiographic exam utilized (88.57%). Radiolucent lesions accounted for 89 cases (63.57%) and the unilocular form was present in 114 cases (81.43%). A total of 93 cases had histopathological analyses and the periapical cyst was the most frequent lesion. In the other 47 lesions, the diagnosis was conducted by clinical and radiographic management. Bone lesions were frequent, being noted on first visit in approximately 30% of patients; in 1/3 of the cases, the diagnoses were completed with a combination of clinical and radiographic exams.
The Agreement Rate between Radiographic Interpretation and Histopathologic Diagnosis of Jaw Lesions
Radiology Research and Practice
Background. To determine the agreement rate between histopathologic diagnosis and radiographic interpretation of jaw lesions. Methods. Cases with jaw pathologies that have diagnostically adequate histopathologic samples and radiographic examinations were reviewed retrospectively. Two board-certified oral and maxillofacial pathologists (OMFP) independently determined the histopathologic diagnosis, while two board-certified oral and maxillofacial radiologists (OMFR) determined the radiographic interpretations independently. Then the histopathologic diagnosis and the radiographic interpretation were compared for agreement. Results. A total of 104 cases (53% females) were included with a mean age of 31 years. The agreement rate between histopathologic diagnosis and radiographic interpretation was 49%. OMFP required OMFR consultations to reach a diagnosis in 16% of cases. The most commonly encountered lesions were by far odontogenic cysts of inflammatory origin and the agreement for this...
RADIOGRAPHIC FEATURES OF INTERNAL STRUCTURE IN JAW LESIONS (Review article)
2019
Background : The internal structure of jaw lesions demonstrates different characteristics and distinctions. They may be varied in features such as the four variations of internal structure presented in ameloblastoma. Each type represents distinctive characteristics which depict the natures of respective lesion. Unquestionably required for lesion identification, internal structure becomes an essential radiographic aspect to differentiate the characteristic of a lesion. Several specific attributes of internal structure are utilized to distinguish each diagnosis. Thus, it is necessary to conduct specific assessment to discover the features of internal structure. Objective : To identify different radiographic features of internal structure in jaw lesions. Discussion : This article scrutinizes the internal structure of jaw lesions such as Pattern of Bones Destruction and Septation in Bone Lesions from several article reviews. A number of variances exist in the features of internal struct...
Application of Computed tomography in jaw lesions: A comprehensive review
2021
Radiology is an essential aid to the diagnosis, treatment planning and monitoring of oral diseases. Advances in imaging technology have revolutionized our ability to study image and understand pathology on a macroscopic level. Digital radiology is the next step in the evolution of radiology, its features like significant reduction in radiation exposure, the ability to digitally manipulate the captured image to produce a more diagnostic image, reduction in time between exposure and image interpretation, and digital documentation of patient’s records make it a valuable diagnostic aid in hands of a clinician. New diagnostic modalities, like computed tomography has revolutionized dental diagnosis by multi planar reconstructions and allowing virtually any view to be selected, making three dimensional imaging possible by a few clicks on the computer. Hence; we aim to summarize some of the important aspects of role of Computed tomography in jaw lesions.
Journal of Oral and Maxillofacial Pathology, 2016
Introduction: The jaw can be affected by several lesions that manifest in the oral cavity, but little is known about their distribution patterns in various populations. Aims and Objectives: This study presents the frequency and distribution of biopsied jaw lesions recorded in Faculty of Dentistry and gathers the information including provisional and final diagnosis of the lesions. Material and Methods: Biopsy of 1938 lesions (2008-2013) was reviewed and 1473 lesions were included in this study. The provisional diagnosis and histopathological validations of lesions were compared. Data on the location of the lesion, as well as patient demographics, were also evaluated. The lesions were divided into three major groups as 1-developmental/reactive and inflammatory lesions of the jaw, 2-cystic lesion and 3-tumor and tumor-like lesions. Statistical Analysis: The variables were recorded and analysed using descriptive statistics. Results and Observations: Three hundred and ninety-six lesions were in Group 1 and periapical granuloma was the most frequent diagnosis. Seven hundred and eighty-nine lesions were in Group 2 and the radicular cyst was the most frequent diagnosis. Two hundred and eighty-eight lesions were in Group 3 and the keratocystic odontogenic tumor was the most frequent. Two hundred and ninety-one biopsied lesions were in disagreement with respect to the diagnoses on clinical and histopathological examination. Conclusion: Consequently, a provisional diagnosis of some of the malignant lesions was reactive, inflammatory, cystic or benign lesions, therefore the importance of evaluation of the specimen is emphasized.
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.
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...
