Three experiments examine multimodal integration of tone pitch (high/low), facial expression stimuli (happy/angry), and responses (happy/angry) in a compatibility paradigm. When the participants' task is to imitate facial expressions (Experiment 1), smiles are facilitated by high tones whereas frowns are facilitated by low tones. Experiments 2 and 3 further analyse this effect and show that the...

A 26-year, 9-month-old woman had chief complaints of mandibular protrusion and facial asymmetry. Extraoral examination indicated mandibular deviation to the left side, severe facial asymmetry, and a concave profile. Because the patient had a vertical maxillary height difference and an occlusal plane cant together with maxillary retrusion, a differential downgraft and advancement surgery with Le...

This paper presents a novel type-2 Fuzzy logic System to define the Shape of a facial component with the crisp output. The Fuzzy model, designed in this paper, takes crisp value of width and height of a facial component and produces the crisp value of Shape for different facial components. The Fuzzy model is designed using Matlab 6.5 and Visual Basic 6.0 and tested with the facial components ex...

PURPOSE This study aimed to assess the three-dimensional (3D) facial changes after orthognathic surgery by evaluating the spherical coordinates of facial lines using 3D computed tomography (CT). MATERIALS AND METHODS A 19-year-old girl was diagnosed with class III malocclusion and facial asymmetry. Orthognathic surgery was performed after orthodontic treatment. Facial CT scans were taken befo...

This study, reporting the results of a 2012 Master’s dissertation, of 131 skulls from 6 Classical to Medieval populations in Macedonia and England examined the relationship between craniometric variables and dental anomalies of shape, number, and position. Standard craniometric landmarks were measured and dental anomalies of shape, number, and position were recorded and tested for associations ...

The aim of this study was to investigate the effects of the headgear-Herbst appliance with mandibular step-by-step advancement followed by retention with the headgear activator. The sample comprised 22 consecutively treated patients (13.2 +/- 1.5 years old) and 31 matched controls (12.6 +/- 1.3 years old). Lateral cephalograms were obtained at the beginning of treatment, after 6 months (at comp...

This study determined the prevalence of signs and symptoms of temporomandibular joint dysfunction (TMD) in children with and without generalized joint hypermobility (GJH). Twenty children with GJH, ages 4-19, and 20 age- and sex-matched control children completed a TMD signs/symptoms history and underwent an examination consisting of palpation of the joints and associated musculature for tender...

This article will discuss and evaluate the potential conditions that can present in patients who require or already have had multiple anterior tooth extractions; the proper considerations for the use of ovate pontics in the treatment plan also will be discussed. While the ultimate treatment decisions must be determined on a case-by-case basis, it is important to recognize in advance the various...

The project aimed at finding the answers to the following two questions: to what extent does a change in size, height or width of the selected facial features influence the assessment of likeness between an original female composite portrait and a modified one? And how does the sex of the person who judges the images have an impact on the perception of likeness of facial features? The first sta...
