Nowadays, radiography is a necessary procedure in diagnosis and treatment of patients with dental problems. According to the ALARA (as low as reasonably achievable) principle, dentists must take radiographs of sufficient quality at the lowest possible radiation dose to the patients. The assessment of patient dose on panoramic radiography is difficult because of dynamic nature of the imaging pro...

In this paper we present a panoramic depth imaging system. The system is mosaic-based which means that we use a single rotating camera and assemble the captured images in a mosaic. Due to a setoff of the camera’s optical center from the rotational center of the system we are able to capture the motion parallax effect which enables the stereo reconstruction. The camera is rotating on a circular ...

This study aimed at evaluating the validity of cone-beam computed tomography (CBCT) for assessing mandibular bone quality using the Klemetti classification. The morphology of the endosteal mandibular cortex of 30 (60 hemi-mandibles) postmenopausal women between the ages of 45 and 80 years was evaluated based on the Klemetti classification in panoramic radiographs used as reference images. After...

A mirror pyramid consists of a set of planar mirror faces arranged around an axis of symmetry and inclined to form a pyramid. By strategically positioning a number of conventional cameras around a mirror pyramid, the viewpoints of the cameras’ mirror images can be located at a single point within the pyramid and their optical axes pointed in different directions to effectively form a virtual ca...

OBJECTIVES To report radiographic findings of examinations with computed tomography (CT) of impacted lower third molars with an intimate relation to the mandibular canal and to investigate how findings of a dark band across the roots of the lower third molar on panoramic views correspond to the CT findings. METHODS CT images of 90 lower third molars (64 patients, mean age 34.6 years) in which...

AIM To compare the use of film-based periapical radiographs and digital panoramic images displayed on monitor and glossy paper in the assessment of the periapical status of the teeth. METHODOLOGY A total of 86 subjects were examined. All participants underwent a full-mouth radiographic survey (14 periapical radiographs) and a digital panoramic radiography. The periapical status of all apprais...

The purpose of this study was to compare the efficiency of conventional and digital panoramic images for localization of mental and mandibular foramens. Six dry edentulous human mandibles were used in the study. Conventional and digital panoramic images were obtained and the vertical and horizontal measurements were performed for localization of mental and mandibular foramens on the images. The...

Panoramic video provides immersive and interactive experience by enabling humans to control the field of view (FoV) through head movement (HM). Thus, HM plays a key role in modeling human attention on panoramic video. This paper establishes a database collecting subjects’ HM positions on panoramic video sequences. From this database, we find that the HM data are highly consistent across subject...

BACKGROUND/OBJECTIVE Panoramic radiography has a great place among imaging techniques because of its enormous advantages. One of the characteristics of an ideal imaging technique is to supply precise measurement. The purpose of the current study was to evaluate the accuracy of linear measurements of the jaws on panoramic radiographs. PATIENTS AND METHODS In this study, the vertical distances ...

The purpose of this study was to evaluate the feasibility of dental panoramic radiography for dental arch evaluation in small animals. The dental arches of four Beagles, one Shih Tzu dog, and three Korean shorthaired cats were radiographed using human panoramic X-rays. All animals were under general anaesthesia during the examination. The animals’ heads were placed horizontal to the panoramic d...
