Over the past two decades, orthodontists have performed many studies on facial profiles and the results of these studies have emphasized the use of profile view to detect orthodontic malocclusions. Some studies consider lateral cephalometric radiography (LCR) as the best method to examine the profile view. It is about a century that lateral cephalometry was introduced and then used as a standard instrument for diagnosis and treatment of orthodontic treatment. Today, it is also necessary to use it in the orthodontic treatment. Cephalometric tracing or template method is used as the standard lateral cephalometric assessment method. Tracing is done because it reduces the amount of information on the film to a considerable extent and prepares cephalograms for subsequent analyzes. Despite the fact that LCR is already prescribed prior to orthodontic treatments in many European countries, very few orthodontic treatments are based on data from cephalometric analysis.The purpose of this study was to determine the validity and reliability of visual inspection of the LCR in determining dento- skeletal characteristics.
