statement of the problem: tonsilloliths are relatively common clusters of dystrophic calcified material that form in the tonsillar crypts , mostly the palatine tonsils. although they may be asymptomatic, some cause halitosis, cough, dysphagia, and foreign body sensation, as well as otalgia. since tonsilloliths can be detected on panoramic views as radiopaque lesions, and misdiagnosis may lead t...

Background: This study evaluated and determined the proximity of an impacted third mandibular molar (TMM) to the inferior alveolar canal (IAC) by using CBCT and digital panoramic radiography. Materials and Methods: This descriptive-analytic research applied CBCT and panoramic radiographs for 60 subjects (28 men, 32 women). Subjects selected showed a close proximity about the TMM to the inferior...

AIM The purpose of this study was to evaluate the effect of tube current reduction on image quality using medium and regular intensifying screens as well as a digital system for panoramic radiography. METHODS AND MATERIALS A total of 150 panoramic images of 75 patients were obtained in the study. The initial images were taken at standard exposure settings, and secondary images were exposed wi...

OBJECTIVES To compare panoramic radiographs made with the Scanora dental program and bitewing radiographs in the assessment of marginal bone tissue. MATERIALS AND METHODS Panoramic and posterior bitewing radiographs were made for 96 consecutive patients. Six observers assessed marginal bone level, and five observers identified the presence or absence of vertical bone defects and furcation inv...

In this paper, we propose a robust and efficient method to integrate the multi-view panoramic range data using the global features acquired from panorama range data. In our approach, the planes with similar normal vectors are handled as one group, and multiple plane groups are extracted from the multi-view panoramic range data. Next, the transformation ( r e tation and translation) parameters b...

Nowadays, with rapid advancement of technology, people can roam around the virtual world through the aid of the Internet. One of these advances is a photographic technique called panoramic view where images are captured with elongated field of view using specialized software or equipments. However, the computational cost of generating a panoramic view is high. One of the popular software for ge...

Mosaicing and super resolution are two ways to combine information from multiple frames in video sequences. Mosaicing displays the information of multiple frames in a single panoramic image. Super-resolution uses regions which appear in multiple frames to improve resolution and reduce noise. Simple combination of the two methods is problematic since the alignment used for mosaicing may not be a...
