The facial width-to-height ratio (fWHR) is a perceptual cue that affects the perception of psychological traits such as dominance. current research examined whether fWHR would impact dominance and emotional intensity when expressing emotions. In study one, we expressions (EFEs) modify visually perceivable by following specific pattern reflecting associated with basic EFEs. We found EFEs differe...

OBJECTIVE To compare the vertical facial and dental arch dimensional changes occurring with extraction and nonextraction orthodontic treatments. STUDY DESIGN Cross-sectional comparative study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital, Karachi during the period 2003 to 2005. METHODOLOGY Data were collected using records of patients who visited the study setting during t...

BACKGROUND The aim of this study was to determine the association between facial pattern according to Ricketts cephalometric analysis, and prevalence of third molar agenesis, taking subject age and gender as control variables. MATERIAL AND METHODS An epidemiological survey was conducted based on a sample of 224 candidates for orthodontic treatment aged 12 to 24 (n=224). Third molar agenesis w...

Aim of the study was to investigate the change in lower anterior facial height (LAFH) following 1st premolar extraction and incisor retraction in bimaxillary proclination orthodontic cases. 35 patients (M:F ratio 18:17) with bimaxillary protrusion with age ranging from 14-17 years (mean calculated age 15.6 years) were treated with 1st premolar extractions followed by retraction of the upper and...

The maxilary nerve can be block in the pterygopalatine fossa, entering from oral cavity via greater palatine canal. The aim of this study was to analyse the volume of the pterygopalatine fossa and its relationship with upper facial height and cephalic indexes. In 71 human adults skulls, without sex distinction, was determined the volume of the pterygopalatine fossa and cephalic and upper facial...

OBJECTIVE To determine if there is a significantly different effect on vertical changes during phase I palatal expansion treatment using a quad helix and a bonded rapid maxillary expander in growing skeletal Class I and Class II patients. MATERIALS AND METHODS This retrospective study looked at 2 treatment groups, a quad helix group and a bonded rapid maxillary expander group, before treatmen...

The importance of understanding all gender facial differences is critical in providing a successful cosmetic outcome. Men are a growing segment of the cosmetic industry. Understanding of the male face and its appropriate treatment with minimally invasive cosmetic procedures are essential. The aim was to investigate various facial ratios in Indian American men and to compare them with the Indian...

Facial width-to-height ratio is a sexually dimorphic metric that is independent of body size and may have been shaped by sexual selection. We recently showed that this metric is correlated with behavioral aggression in men. In Study 1, observers estimated the propensity for aggression of men photographed displaying neutral facial expressions and for whom a behavioral measure of aggression was o...

Recent studies suggest that judgments of facial masculinity reflect more than sexually dimorphic shape. Here, we investigated whether the perception of masculinity is influenced by facial cues to body height and weight. We used the average differences in three-dimensional face shape of forty men and forty women to compute a morphological masculinity score, and derived analogous measures for fac...

Two groups of children with low (n = 29) and high (n = 29) MP-SN angles were followed longitudinally from 6 to 15 years of age. The purpose was to thoroughly examine associations between vertical craniofacial growth and mandibular growth rotation. Correlations between dimensional and rotational variables occurred in different variable pairs in the two groups and changed with age. Increase in po...
