fibrous dysplasia (fd) is an osseous growth dis-order, producing immature bone and characte-rized by the replacement of normal bone with fibro-osseous connective tissue. it is a bone dys-plasia that has the potential to cause significant cosmetic and functional disturbances, particularly in the craniofacial skeleton. cra-niofacial fibrous dysplasia is one of the three types of polyostotic fibro...

One of the most important developments in field radiology is that imaging process has started to take place digital environment. The advantages radiography increase interest dentists radiography, and nowadays systems are replacing conventional systems. reasons for using fast access image, quality easy storage transmission image. Nowadays, clinicians can digitize anything recall it with patient....

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

objective: vertical root fracture (vrf) is among the most common causes of endodontic treatment failures. this study aims to compare charge-coupled devices (ccd) and photostimulable phosphor plates (psp) for detection of vertical root fractures in endodontically treated teeth.   methods: in this diagnostic in vitro study, 40 maxillary anterior teeth were selected and after preparation and root ...

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 ...

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...

introduction: vertical root fracture (vrf) is a complication which is chiefly diagnosed radiographically. recently, film-based radiography has been substituted with digital radiography. at the moment, there is a wide range of monitors available in the market for viewing digital images. the present study aims to compare the diagnostic accuracy, sensitivity and specificity of medical and conventi...

introduction: good radiographs are required for endodontic therapy and because some patient’s are intolerant to intraoral films and/or sensors, this can cause complications in endodontic treatment. extraoral film placement can be used to obtain clinically diagnostic and working radiographs. materials and methods: the no. 2 receptor was placed against the model ’ s cheek and centered in the mola...

introduction: despite being the gold standard as well as a routine technique in endodontics, radiographic working length (wl) determination owns many drawbacks. electronic apex-locators (eals) are recommended to complement radiographies. the aim of this study was to evaluate the perceptions of iranian general dental practitioners (gdps) towards using radiography and eal. methods and materials: ...
