OBJECTIVE The purpose of this study was to establish Tweed's cephalometric norms for Indian Bengali population and to compare it with Caucasian norms. MATERIALS AND METHODS The participants were of 50 adults with normal occlusion and pleasant profile. Lateral cephalograms were taken in natural head position, and cephalometric norms were established using Tweeds diagnostic triangle. RESULTS ...

T he introduction of the cephalometer to orthodontics provided the avenue for the creation of cephalometric analyses. Cotton, Takano, and Wong,6 Altemus,’ Chang4 and Drummondg were among those who provided the clinician with guides and standards for specific racial groups which were different from the classic Caucasian norms found in most analyses. The present study was concerned with a single ...

This paper presented 3D cephalometric analysis on DICOM data from I-CAT CT cone-beam machine consisted of averages and standard deviations from 20 Thai males from 19 to 70 year (average 33.53 ± 14.08 year) and 20 Thai females from 16 to 70 year (average 32.60 ± 15.37 year). The angular measurements consisted of 49 lateral angular measurements and 9 frontal angular measurements while linear meas...

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...

In this paper, we propose a new generic landmark detection method for 2D images. Our solution is based on the use of ensembles of Extremely Randomized Trees combined with simple pixel-based multi-resolution features. We apply our method on a novel dataset of microscopic zebrafish images. This method was also tested on datasets of cephalometric images during the Automatic Cephalometric X-Ray Lan...

Objectives: To determine the posteroanterior cephalometric norms in Palestinian adults, and to compare the Palestinian norms with the norms of other ethnic groups. Materials and Methods: PA cephalometric radiographs for 70 Palestinian adults aged between 17-23 years were selected on the basis of Class I molar relationship, good facial symmetry, and no history of previous orthodontic treatment. ...

The use of computers as an auxiliary instrument for case evaluation and procedures in health sciences is not new, and their advantages are well known. A growing number of orthodontists are using computerized systems for cephalometric analysis. Thus, this study evaluated the reliability of both computerized and manual methods used for creating profile cephalograms. Fifty profile radiographs were...

The Turin Shroud (TS) is a linen cloth commonly associated with Jesus Christ, his crucifixion and burial. Several medical specialists have debated the injuries of the TS Man, nevertheless there are no detailed and quantitative data about the anatomy of the TS face. The purpose of this study was to analyse the cephalometric measurements of the face image of the TS. The TS face image was acquired...

PURPOSE Lateral cephalometric films were examined for their validity as a tool for the postoperative evaluation of palatal implant placement. MATERIALS AND METHODS Cephalometric and histometric data of 20 partially edentulous human cadaveric maxillae were compared. Lateral cephalograms of the specimens were made, and the palatal complex was pencil traced. In addition, low-dose dental computer...
