BACKGROUND AND AIM Maximal mouth opening (MMO) is used as a marker of masticatory pathology. However, MMO among children varies considerably with their age, height, sex, and race. While accurate percentile of normal mouth opening and relationship with anthropometric measurement are not precisely defined for the Indian population, we designed prospective, observational study to define the percen...

A large biracial sample of children were assessed for open mouth posture and maxillary arch width once a year for 3 years. Analyses revealed that although the youngsters exhibited open-mouth posture at high levels, over time, there was a significant decrease in this behavior. Racial and gender differences, as well as a race-by-time interaction, were also evidenced. The children displayed a sign...

the study area is the rahmat anticline. this is located in fars province (sw fold simple zagros belt). the aims of this study are morphotectonic studies and structural analysis in several parts of area. for this purpose: 1) morphotectonic indices, drainage basin shape index (bs), mountain front sinuosity index (smf) and valley floor width – height ratio (vf) were measured by digital elevation m...

Normal human observers compared either the width, height or area of two simultaneously-presented shapes (the standard and the test), with a cue to indicate which decision had to be made. On 'area' trials, test width was a random variable, ensuring that neither shape (aspect ratio), width nor height by themselves was a reliable signal. Weber fractions for width and height of both ellipses and re...
