An evaluation of the errors in cephalometric measurements on scanned cephalometric images and conventional tracings.
The aim of this investigation was to compare the classic method of tracing by hand with a computerized method, where the lateral cephalograms were scanned at 300 dpi and digitized onscreen. The inter- and intra-observer errors were investigated for tracing and digitizing errors. Thirty lateral cephalograms were scanned into digital format at 300 dpi, displayed on a high-resolution monitor, and ...
متن کاملComparison of cephalometric measurements with digital versus conventional cephalometric analysis.
The aim of this study was to evaluate the accuracy and reliability of angular and linear cephalometric measurements using a computerized method of direct digital radiographs. This was then compared with the measurements obtained with a computerized method that uses a digitizing pad and hand tracing of printout radiographs. Pre-treatment digital cephalometric radiographs of 125 patients were tra...
متن کاملAccuracy of Linear Cephalometric Measurements with Scanned Lateral Cephalograms
Digital Cephalometry needs to be as accurate as conventional cephalometry in order to be taken as a standard of care in contemporary orthodontics. Objective of this study was to compare the accuracy of linear cephalometric measurements on scanned cephalograms with manual tracing as the gold standard. Cephalometric analysis of specified linear measurements was performed on cephalometric radiogra...
متن کاملAccuracy of Angular Cephalometric Measurements with Scanned Lateral Cephalograms
Digital Cephalometry is fast becoming the standard of care in contemporary orthodontic diagnosis. Before it can completely take over the traditional methods, it must be demonstrated that it is as accurate as conventional cephalometric radiography. This study was done to compare the accuracy of angular cephalometric measurements on scanned cephalograms with manual tracing as the gold standard. C...
متن کاملComparison of cone-beam computed tomography cephalometric measurements using a midsagittal projection and conventional two-dimensional cephalometric measurements.
OBJECTIVE This study investigated whether it is possible to use a two-dimensional (2D) standard in three-dimensional (3D) analysis, by comparing the angles and lengths measured from a midsagittal projection in 3D cone-beam computed tomography (CBCT) with those measured by 2D lateral cephalometric radiography (LCR). METHODS Fifty patients who underwent both LCR and CBCT were selected as subjec...
