AIM The purpose of this study was to predict the skeletal maturation status based on the assessment of cervical vertebrae from lateral cephalometric radiographs and to compare these findings with the skeletal maturity of the same individuals judged from the hand-wrist radiographs. MATERIALS AND METHODS Lateral cephalometric and left hand-wrist radiographs of 393 Caucasian children from 8 to 1...

OBJECTIVE This study compared lateral radiographs of the nasopharynx (LN) and lateral cephalometric radiographs (LC) used to assess nasopharyngeal airway space in children. MATERIAL AND METHODS One examiner measured the nasopharyngeal space of 15 oral breathing patients aged between 5 and 11 years old by using LN and LC. Both assessments were made twice with a 15-day interval in between. Inte...

Digital Cephalometry is fast becoming the standard of care in contemporary orthodontic diagnosis. Before it can completely take over the traditional methods, it must be demonstrated that it is as accurate as conventional cephalometric radiography. This study was done to compare the accuracy of angular cephalometric measurements on scanned cephalograms with manual tracing as the gold standard. C...

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...

OBJECTIVE To determine whether mouth breathing children present the same cephalometric patterns as patients with obstructive sleep apnea syndrome (OSAS). METHOD Cephalometric variables were traced and measured on vertical lateral cephalometric radiographs. The cephalometric measurements of 52 mouth and 90 nose breathing children were compared with apneic patients. The children had not undergo...

OBJECTIVES Numbers of dental panoramic tomographs (DPTs) and lateral cephalometric radiographs (LCRs) outweigh other radiographic examinations in 7- to 12-year-old Finns. Orthodontists and general practitioners (GPs) involved in orthodontics hold therefore the highest responsibility of the exposure of children to ionising radiation with its risks. Against this background, lack of reports on the...

cephalometric norms of mcnamara analysis have been studied in various populations due to their optimal efficiency. dolphin cephalometric software greatly enhances the conduction of this analysis for orthodontic measurements. however, dolphin is very expensive and cannot be afforded by many clinicians in developing countries. a suitable alternative software program in farsi/english will greatly ...

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...

BACKGROUND The patient's head can be slightly rotated sagitally vertically or transversely within the head holding device. Because of such improper positions due to the head rotation, an error can occur in cephalometric measurements. The purpose of this study was to identify the potential projection errors of lateral cephalometric radiograph due to head rotation toward X-ray film in the vertica...
