background diagnosis and accuracy in determining the exact location, extent and configuration of bony defects of the jaw are of utmost importance to determine prognosis, treatment planning and long-term preservation of teeth. if relatively accurate diagnosis can be established by radiography, proper treatment planning prior to treatment procedures will be possible. objectives the aim of the pre...

introduction: knowledge of the anatomic location and dimension of the molar pulp chamber may preserve healthy pulp during operative procedure and reduce risk of perforation of chamber during access preparation. a review of literatures regarding the morphology of pulp chamber however revealed very little information; so the aim of this in vivo study was to measure the dimensions of first molar p...

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...

objectives : optimum viewing conditions facilitate identification of radiographic details and decrease the need for retakes, patients’ costs and radiation dose. this study sought to evaluate the effects of different viewing conditions on radiographic interpretation. materials and methods: this diagnostic study was performed by evaluating radiograph of a 7mm-thick aluminum block, in which 10 hol...

introduction: the image quality as well as film speed is influenced by the film processing conditions. different combinations of films and processing methods affect the diagnostic accu-racy. temperature and developer exhaustion result in different image quality. the purpose of this study was to evaluate the influence of film type and processing conditions on caries detec-tion.  material and met...

Radiographic artifacts may mimic a clinical feature, impair image quality, or obscure abnormalities. With the development of digital radiography (DR), a new set of artifacts is introduced. Regardless of the technology, the classic technical errors that occur with film screen radiography still occur using DR. Artifacts created using computed radiography, DR, and incorrect image processing are di...

OBJECTIVES To survey the current radiographic prescriptions in dental implant assessment amongst dentists in Brazil. METHODS Sixty-nine dentists were interviewed during a dental implant meeting by two calibrated graduate students, using a 19-question questionnaire, considering imaging modality options both for pre-operative implant site assessment and for follow-up, particularly with respect ...

statement of problem: digital measurement of rvg may improve diagnostic interpretation of radiographs in terms of accuracy, although it has been shown that validity of linear measurements of interproximal bone loss could not be improved by basic digital manipulations. purpose: the aim of this study was to evaluate the accuracy of radiovisiography (rvg) in the linear measurement of interproximal...
