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 ...

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.

Role of lateral cephalograms in assessing severity and difficulty of orthodontic cases
American Journal of Orthodontics and Dentofacial Orthopedics, 2001To assess the role of lateral cephalometric films in the evaluation of orthodontic patients, 16 certified orthodontists examined 80 sets of dental casts and lateral cephalograms. The patients included 5 subgroups: Class I with mild crowding, Class II Division 2, Class III, open bites, and bimaxillary protrusion. A 5-point Visual Analogue Scale was used

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.

Relationship of nasal and skeletal landmarks in lateral cephalograms of preschool children
Forensic Science International, 2009The purpose of this study was to investigate the relationship between cephalometric nasal and skeletal landmarks in preschool children. Lateral cephalograms of 80 Japanese preschool children (40 boys, mean age 5.4+/-0.3 years; 40 girls, mean age 5.2+/-0.1 years; total mean age 5.3+/-0.3 years) were traced, and 22 skeletal and 3 soft-tissue nasal points

Reproducibility of airway dimensions and tongue and hyoid positions on lateral cephalograms
American Journal of Orthodontics and Dentofacial Orthopedics, 2005The aim of this study was to evaluate the reproducibility of airway dimensions and tongue and hyoid positions on lateral cephalometric radiographs.Three lateral cephalograms each of 30 patients were obtained in natural head positions at 30-minute intervals. Twelve measurements, including pharyngeal airway dimensions and tongue and hyoid positions, were
