A study on the reproducibility of cephalometric landmarks when undertaking a three-dimensional (3D) cephalometric analysis
OBJECTIVES Cone Beam Computerized Tomography (CBCT) allows the possibility of modifying some of the diagnostic tools used in orthodontics, such as cephalometry. The first step must be to study the characteristics of these devices in terms of accuracy and reliability of the most commonly used landmarks. The aims were 1- To assess intra and inter-observer reliability in the location of anatomical...
متن کاملAutomatic computerized radiographic identification of cephalometric landmarks.
Computerized cephalometric analysis currently requires manual identification of landmark locations. This process is time-consuming and limited in accuracy. The purpose of this study was to develop and test a novel method for automatic computer identification of cephalometric landmarks. Spatial spectroscopy (SS) is a computerized method that identifies image structure on the basis of a convoluti...
متن کاملAn Evaluation of Cellular Neural Networks for the Automatic Identification of Cephalometric Landmarks on Digital Images
Several efforts have been made to completely automate cephalometric analysis by automatic landmark search. However, accuracy obtained was worse than manual identification in every study. The analogue-to-digital conversion of X-ray has been claimed to be the main problem. Therefore the aim of this investigation was to evaluate the accuracy of the Cellular Neural Networks approach for automatic l...
متن کاملHomology and heterology of cephalometric landmarks: methodological consequences.
Sir, With interest I read the study ‘Effects of maxillary protraction for early correction of class III malocclusion’ by Celikoglu and Oktay (1). The authors should be complimented for careful work. Apparently, much effort was taken to avoid traditional pitfalls in the (prospective) collection of study subjects and controls, in reporting measurement technique and in statistical procedures. But ...
متن کاملCephalometric landmarks identification and reproducibility: a meta analysis.
To assess the magnitude of cephalometric landmarks identification error, we performed a Meta analysis on six pertinent studies. We outline the procedures used to compare and integrate the findings of these-studies. The results are a measure of systematic and random errors involved when locating landmarks on lateral head films. They are presented as standard mean errors and 95% confidence interv...
