Film and digital periapical radiographs for the measurement of apical root shortening
OBJECTIVES The aim of this study was to compare the accuracy and agreement of scanned film and digital periapical radiographs for the measurement of apical root shortening. STUDY DESIGN Twenty-four film and digital [phosphor plate sensor (PPS)] periapical radiographs were taken using the long-cone paralleling technique for six extracted teeth before and after 1mm of apical root trimming. All ...
متن کاملAssessment of periapical status: a comparative study using film-based periapical radiographs and digital panoramic images.
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...
متن کاملDigital processing of film radiographs.
Initial clinical experience with a system for the digitization, processing, and display of film radiographs is described. Film is digitized using a high-intensity laser scanner; the recorded image data may then be subjected to a wide variety of processing options, with display of processed images on television monitors. The possibilities of clinical applications to processing and display of che...
متن کاملA posteriori registration and subtraction of periapical radiographs for the evaluation of external apical root resorption after orthodontic treatment
PURPOSE This study employed a posteriori registration and subtraction of radiographic images to quantify the apical root resorption in maxillary permanent central incisors after orthodontic treatment, and assessed whether the external apical root resorption (EARR) was related to a range of parameters involved in the treatment. MATERIALS AND METHODS A sample of 79 patients (mean age, 13.5±2.2 ...
متن کاملIn vitro evaluation of a method for obtaining periapical radiographs for diagnosis of external apical root resorption.
This in vitro study was conducted to evaluate a method to obtain reproducible periapical radiographs, using individualized positioning devices, of upper central incisors submitted to simulated orthodontic movement. Linear measurements of tooth length were carried out on 29 extracted human central incisors. The teeth were radiographed in a tissue simulator, at different inclinations in the bucco...
