Individual and average growth patterns of the facial dimensions Nasion-Gnathion and Sella-Gonion, as related to statural growth were studied. The sample consisted of 134 girls aged 7-14 years. Data were analysed using a multivariate extension of the multilevel model for longitudinal data. The results confirmed that the mean growth curves of Nasion-Gnathion, Sella-Gonion and body height parallel...

The study examines the relationships between different craniometric distances and the nasion-gnathion (N-Gn) distance which represents the lower two thirds of the face in vertical dimension determination. The highest degree of correlation (r = 0.9217; p < 0.05) was observed between the N-Gn and zygion-zygion (Zy-Zy) distances. The N-Gn distance could be determined using the formula N-Gn = Zy-Zy...

background: malocclusion, as a worldwide issue, can cause a lot of problems for patients. panoramic (pr) and lateral cephalometric (lcr) radiographs are both usually indicated for orthodontic treatments. the aim of this study was to analyze vertical and sagittal parameters of both jaws on prs and to compare them on lcrs. materials and methods: in this cross sectional study, 61 samples from all ...

Since from the introduction of cephalometric analysis in diagnosis and orthodontic treatment planninjg, it plays a major role .So many efforts have been made by various studies to standardize the values for different reces , to minimize the distortion and magnification , to create universally accepted analysis, even after this still so many limitations are there in diagnosis of orthodontic trea...

Obstructive sleep apnea and hypopnea syndrome (OSAHS) are characterized by repeated pauses in breathing during sleep, usually associated with sleep interruption and decreased oxyhemoglobin saturation. Cephalometric analysis has become an important method in diagnosis, reporting specific craniofacial characteristics such as posterior air pharyngeal space, tongue length and hyoid position, which ...

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...
