Panoramic and intraoral radiographs are the basic imaging modalities used in dentistry. Often they are the only imaging techniques required for delineation of dental anatomy or pathology. Panoramic radiography produces a single image of the maxilla, mandible, teeth, temporomandibular joints and maxillary sinuses. During the exposure the x-ray source and detector rotate synchronously around the ...

Abstract The aim of this article is to discuss the sequelae a missing tooth from normal series dental arch and importance cone beam computed tomography (CBCT) in diagnosis treatment planning such cases. We also correlate position an impacted maxillary premolar as seen on panoramic radiography with CBCT. Routine imaging modalities like intraoral periapical, occlusal, view often give inadequate i...

OBJECTIVE To assess the diagnostic potential of 2 different cone-beam computerized tomography (CT) units and compare this with intraoral digital and conventional film in the detection of chemically created periapical lesions. STUDY DESIGN Periapical lesions were created chemically in 27 intact roots of 23 teeth (6 incisors, 4 canines, 6 premolars, and 7 molars). Cone-beam CT and digital and f...

o bjectives: early diagnosis of incipient and non cavitated carious lesions is crucial for performing preventive treatments. the aim of this study was to compare the effi- ciency of three diagnostic methods of bite-wing radiography, diagnodent, and visu- al examination in diagnosing the incipient occlusal caries of permanent first molars. materials and methods:  in this diagnostic cross-section...

background: in recent decades many guidelines has been conducted by radiation protection organizations about radiation protection in dentistry. this study aimed to evaluate the observance of these guidelines in educational clinics of all dental schools in iran. material and methods: in this cross-sectional study a self-administered questionnaire, based on national radiation protection board (nr...

This review article provides an overview of cone beam (CB) imaging technology and its role in orofacial imaging, including comparison with two-dimensional (2D) radiography and multislice computed tomography (MCT). The radiation dose levels of CB systems are discussed, with reference to those delivered by MCT and common dental 2D views. The large variation in dose levels delivered by CB systems ...

With our study we wanted to compare the diagnostic accuracy of conventional radiography (orthopanoramic and intraoral radiography) and Cone Beam CT (CBCT) for the diagnosis of periapical lesions on the posterior elements of the upper maxilla endodontically treated.The images were analyzed by a radiologist and an endodontist whose interpretation of radiological examinations is unique. Were exami...

This in vivo study evaluated the dissociation quality of maxillary premolar roots combining variations of vertical and horizontal angulations by using X-ray holders (Rinn -XCP), and made a comparison between two types of intraoral radiography systems - conventional film (Kodak Insight, Rochester, USA) and digital radiography (Kodak RVG 6100, Kodak, Rochester, USA). The study sample was comprise...
