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 ...

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 ...

Deformable registration of lateral cephalogram and cone‐beam computed tomography image
Medical Physics, 2021AbstractPurpose: This study aimed to design and evaluate a novel method for the registration of 2D lateral cephalograms and 3D craniofacial cone‐beam computed tomography (CBCT) images, providing patient‐specific 3D structures from a 2D lateral cephalogram without additional radiation exposure.Methods: We developed a cross‐modal deformable registration ...

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.

International orthodontics, 2010
This study compared angular cephalometric values from scanned traditional lateral cephalograms versus CBCT generated slices. Traditional lateral cephalograms (using Orthoceph OC100) and volumetric CBCT imaging (using NewTom 3G Volume Scanner) were taken from 36 patients.

A novel contour-based registration of lateral cephalogram and profile photograph
Computerized Medical Imaging and Graphics, 2018A contour-based automatic registration method of lateral cephalograms and profile photographs is proposed to facilitate the accurate measurement of anteroposterior (AP) position of maxillary central incisors relative to the forehead. There are mainly three steps in the proposed method.

Incidental finding of an enlarged sella turcica on a lateral cephalogram
American Journal of Orthodontics and Dentofacial Orthopedics, 1996The lateral cephalogram is a film that is routinely used in orthodontics. Orthodontists should therefore be familiar with the normal radiographic appearance of the skull as seen on the lateral cephalogram. We present a case of an enlarged sella turcica that was discovered during routine orthodontic workup.

Importance of Lateral Cephalogram in Treating Class III Patients
2014Introduction: The need for an early identification and treatment of the skeletal Class III malocclusion is accepted worldwide. The treatment success in class III patients depends on the malocclusion type and the case individualization. The treatment choice is extremely difficult, and increases with involvement of the skeletal and occlusal structures ...
