Frequency domain Blind Source Separation (BSS) is shown to be equivalent to two sets of frequency domain adaptive microphone arrays, i.e., Adaptive Null Beamformers (ANB). The minimization of the off-diagonal components in the BSS update equation can be viewed as the minimization of the mean square error in the ANB. The unmixing matrix of the BSS and the filter coefficients of the ANB converge ...

AIM Whether or not the dental relationship correlates with skeletal relationship in the sagittal plane is an area of interest for orthodontic diagnosis and treatment planning. Thus, the aim of this study was to investigate the correlation of the dental malocclusion and the skeletal malocclusion in the sagittal plane among Saudi orthodontic patients. MATERIALS AND METHODS Orthodontic dental ca...

The aim of this study was to assess the sagittal skeletal jaw base and dental arch relationships among adult orthodontic patients. 152 (male: 69 and female: 83; 21.4±3.48 years of age) patients’ dental study model casts and pretreatment 2D lateral cephalometric radiographs derived from CBCT 3D images were randomly selected. Paired t-test was performed to assess the difference between the examin...

Introduction: In orthodontic diagnosis and treatment planning an accurate evaluation of sagittal jaw relationship is important. To assess the antero-posterior jaw discrepancy between maxilla and mandible, numerous angular and linear measurements have been in corporate so as to reach correct diagnosis. So the purpose of this study is to compare ANB angle, Wits appraisal, Beta angle and W angle u...

The aim of this study was to evaluate the oropharyngeal (OP) and nasal passage (NP) volumes along with various airway variables of patients with normal nasorespiratory functions having different dentofacial skeletal patterns and to evaluate the correlations between different variables and the airway. One hundred and one patients (57 males and 44 females, aged 14-18 years) having pre-treatment c...

The causal relationships between oral function and craniomandibular morphology are poorly understood. The aim of this study was to determine whether quantifiable features of masticatory jaw movements and associated EMG activity correlated with variation in morphology as defined by the ANB angle. Thirty-six healthy subjects with no previous orthodontic treatment, asymptomatic masticatory muscles...

Objective. To evaluate the difference between chronological and dental age, calculated by Willems and Cameriere methods, in various skeletal patterns according to Steiner's ANB Classification. Methods. This retrospective cross-sectional study comprised the sample of 776 participants aged between 7 and 15 years (368 males and 408 females). For each participant, panoramic images (OPT) and laterol...

The aim of this retrospective, cross-sectional study was to assess whether mild and severe Class II division 1 subjects have craniofacial and upper airway characteristics, which relate to the severity of Class II as judged by overjet or ANB angle. The sample consisted of pre-treatment lateral cephalograms and dental casts of 131 males and 115 females (mean age 10.4 ± 1.6). Inclusion criteria we...

Amaç: Bu çalışmanın amacı yüzün sagittal yön sınıflamasında kullanılan sefalometrik ölçümlerin farklı malokluzyon tiplerinde tanısal güvenilirliklerini ve geçerliliklerini incelemektir.
 Gereç Yöntem: retrospektif çalışmada 65 kız (yaş ortalaması 15,3±1,22) erkek 15,4±1,92) toplam 130 hastanın ortodontik diagnostik kayıtları başlangıç radyografları çalışma materyali olarak belirlenmiştir. ...

ANB-spermine is a photoaffinity analog of the naturally-occurring polyamine, acetylspermine. ANB-spermine was used to determine its binding sites on naked double stranded DNA, at the nucleotide level, using a modification of the primer extension technique. A total of 1,275 nucleotides was examined in 5 sequences of DNA from Saccharomyces cerevisiae. Binding sites were non-random. The primary de...
