Heritability of nasal characteristics assessed using lateral cephalograms
American Journal of Orthodontics and Dentofacial Orthopedics, 2022The midface and nasal bones have a significant influence on facial esthetics. Being able to predict the ultimate size of a growing patient's nose may influence the orthodontic treatment plan. Our study aimed to determine whether significant heritability exists between parents and children using multiple soft and hard tissue measurements of nasal ...

Comparison of measurements from photographed lateral cephalograms and scanned cephalograms
American Journal of Orthodontics and Dentofacial Orthopedics, 2007In this study, we investigated whether a digital photograph of a lateral cephalometric radiograph can produce measurements as accurate as those from a digital image created with a flatbed scanner.Twenty pretreatment lateral cephalograms were randomly selected from the patient files at Chesterfield Royal Hospital. Each radiograph was photographed with a

A Composite Photographic Image – could it Replace a Lateral Cephalogram?
Journal of Orthodontics, 2017Computer software allows a photograph of patient's face and a photograph of their dental casts to be combined into one image, similar to that seen in a lateral cephalogram. The aim of this study was to assess the agreement between the measurements carried out on this novel composite photographic image and those taken from a lateral cephalogram of the ...

Automatic analysis of lateral cephalograms based on high-resolution net
American Journal of Orthodontics and Dentofacial Orthopedics, 2023Cephalometric analysis is essential in orthodontic treatment, and it is progressing toward automatic cephalometric analysis. This study aimed to establish a cephalometric landmark detection model on the basis of a high-resolution net and improve the accuracy with high resolution.A total of 2000 lateral cephalograms were collected to construct a dataset,

A comparison of scanned lateral cephalograms with corresponding original radiographs
American Journal of Orthodontics and Dentofacial Orthopedics, 2006Digital cephalometric radiography is gaining popularity in orthodontic practices. However, few studies have compared measurements and superimpositions on analog radiographs with those made on scanned digital images. The objectives of this study were to evaluate distortion associated with scanning lateral cephalograms and printing to hard copy, and to ...

Reliability of landmark recording on film and digital lateral cephalograms
The European Journal of Orthodontics, 1993The aims of this study were: (a) to evaluate reliability of landmark location in digital processed images of film cephalograms of varying quality with that obtained in the films, and (b) to evaluate the pattern of error in landmark location with the two techniques.

Quality Assessment of Lateral Cephalograms Amongst Radiologists and Orthodontists
British Journal of Orthodontics, 1994This study investigated technical errors in the production of lateral cephalograms necessitating a retake and the extent to which the retake, as ordered by the radiologist, actually produced a gain in quality as assessed by the orthodontist. All the rejected lateral cephalograms taken at the Department of Oral Radiology over a period of 1 year were ...
