Introduction: Nowadays, the use of panoramic radiographs for evaluation of uprighting and root parallelism, after the closure of spaces and before the debanding of fixed appliances, often been accepted, and the use of radiography to evaluate the results at the end of orthodontic treatment is discussed.It is not clear whether panoramic radiography reflects the exact mesiodistal position of the ...
Abstract Panoramic radiography is an extraoral modality that provides two-dimensional information about the teeth and maxillofacial skeleton. It a valuable adjunct for diagnosis treatment planning as it facilitates one-time imaging of all teeth, mandible, parts maxilla including large part maxillary sinus, hard palate temporomandibular joints (TMJs). As tomographic image prone to errors artefac...
OBJECTIVE To report the association of pulp calcification with that of cardiovascular disease (CVD) using digital panoramic dental radiographs. MATERIALS AND METHODS Digital panoramic radiographs of patients referred from the angiography department were included if the patient was under 55 years old and had non-restored or minimally restored molars and canines. An oral and maxillofacial radio...
background: one of the most frequent concerns encountered in dental implant treatments is inadequate pre‑operative planning. panoramic radiographs are readily accessible and cost efficient. the aim of this study is to assess the accuracy of vertical measurements in mandibular molar andpremolar region on panoramic radiography. materials and methods : panoramic radiographs were made of a partiall...
To the Editor: I am writing in response to a recent article published in the June issue of Imaging Science in Dentistry by Demirturk Kocasarac and Celenk titled “Effectiveness of digital subtraction radiography in detecting artificially created osteophytes and erosions in the temporomandibular joint.” The authors compared the diagnostic efficacy of panoramic radiography and panoramic digital su...
BACKGROUND The relationship between impacted mandibular third molar and mandibular canal is important for removal of this tooth. Panoramic radiography is one of the commonly used diagnostic tools for evaluating the relationship of these two structures. OBJECTIVES To evaluate the accuracy of panoramic radiographic findings in predicting direct contact between mandibular canal and impacted thir...
introduction: mandibular fracture is the most common facial bone fracture due to facial trauma. a variety of imagings have been used for diagnosis of mandibular fractures. however, the choice of imaging for diagnosis of mandibular fractures is controversial.present study compares the accuracy of the three most common imaging methods in mandibular fracture diagnosis panoramic radiography, corona...
background and aims: tooth displacement changes the periodontium. the aim of orthodontic treatment was desired tooth movement with minimum side effects on the alveolar bone quality. the aim of the present study was to assess changes of alveolar trabeculation among children, youth and adults and the two genders. materials and methods: in this cross-sectional study, 63 patients who had been treat...
background identification of common technical errors during preparation of panoramic radiographs, how affect the quality and interpretation of the radiographs and the techniques used to deal with such errors, might help prevent unnecessary radiation to patients and save their time and money. objectives the current study aimed to identify common errors in the panoramic radiographs taken by post-...
