The panoramic radiograph is an excellent extraoral radiograph to reveal abnormalities and pathologic conditions of the jaws and to show calcification of adjacent soft tissue. A single panoramic radiograph provides a significant image of the maxillofacial skeleton and dentition and often is used as a survey or screening film because of the area it covers. The panoramic radiograph does not provid...

Multi-resolution techniques have been used in a wide range of vision applications. Unfortunately, the costly operation of building a proper pyramid strongly reduces its value as a tool for reducing computational cost. A new approach, physical panoramic pyramid, is introduced in this paper. Physical panoramic pyramid measures multiple resolutions simultaneously resulting in multi-resolution pano...

OBJECTIVE: The present study was aimed at comparing indices obtained from dental panoramic radiographs with bone densitometry results in the identification of individuals affected by osteoporosis/osteopenia. MATERIALS AND METHODS: Panoramic mandibular, mental, antegonial, gonial and mandibular cortical indices calculated with basis on dental panoramic radiographs of postmenopausal women were co...

OBJECTIVE To evaluate the detection of mucous retention cyst of maxillary sinus (MRCMS) using panoramic radiography and cone beam computed tomography (CBCT). STUDY DESIGN A digital database with 6,000 panoramic radiographs was reviewed for MRCMS. Suggestive images of MRCMS were detected on 185 radiographs, and patients were located and invited to return for follow-up. Thirty patients returned...

PURPOSE This study was performed to determine the prevalence of maxillary canine impaction on a basis of a single panoramic radiograph in Bangladeshi population. MATERIALS AND METHODS A random sample of seven hundred panoramic radiographs was collected from the patient record of a dental clinic. All the selected panoramic radiographs were taken from January 2009 to August 2010 by a single pan...

This paper proposes an affine motion compensated prediction (AMCP) method to predict the complex changes between the successive frames in panoramic video coding. A panoramic video is an image-based rendering (IBR) technique [1] which provides users with a large field of view (e.g. 360 degree) on surrounding dynamic scenes. It includes not only the translational motions but also the non-translat...

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 and premolar region on panoramic radiography. MATERIALS AND METHODS Panoramic radiographs were made of a partiall...

Recently multiple panoramic images have emerged and received increasingly interest in applications of 3D scene visualization and reconstruction. Examples of such approaches and applications are discussed throughout the paper. Although many panoramic image acquisition models have been proposed in the literature, there is still a lack in studies about what principles are essential in the design/a...

BACKGROUND Carotid artery calcification may be related to cerebrovascular accident, which may result in death or physical and mental disabilities in survivors. OBJECTIVES Our purpose is to study the association of carotid artery calcification (CAC) on dental panoramic radiographs and two risk factors of cerebrovascular accident (CVA) including hypertension and myocardial infarction (MI). PA...

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...
