Facial expression of emotion is a foundational aspect of social interaction and nonverbal communication. In this study, we use a computer-animated 3D facial tool to investigate how dynamic properties of a smile are perceived. We created smile animations where we systematically manipulated the smile's angle, extent, dental show, and dynamic symmetry. Then we asked a diverse sample of 802 partici...

The principles of decision-analytic decision support, implemented in GeNIe (Graphical Network Interface) and SMILE (Structural Modeling, Inference, and Learning Engine) can be applied in practical decision support systems (DSSs). GeNIe plays the role of a developer's environment and SMILE plays the role of the reasoning engine. A decision support system based on SMILE can be equipped with a ded...

Objective. To evaluate characteristics of smile related to visibility in individuals with cleft lip, alveolus, and palate. Design. Cross-sectional. Setting. HRAC/USP, Brazil. Patients. Individuals with repaired complete unilateral cleft lip and palate (n = 45), aged 15-30 years. Interventions. Frontal facial photographs were obtained in natural and forced smiles (n = 135). Six specialists in pe...

OBJECTIVES The aim of this study was to develop an effective single intraoral, minimally invasive technique to reduce the enlarged tongue base in children with obstructive macroglossia. METHODS We present the anatomic dissection of fresh cadavers and a representative case series of children who underwent submucosal minimally invasive lingual excision (SMILE) with a plasma-mediated radiofreque...

PURPOSE To investigate corneal spherical aberration and corneal asphericity after small incision lenticule extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). METHODS This study enrolled 70 patients having SMILE and 64 subjects receiving FS-LASIK. The preoperative spherical equivalent (SE) was -5.83 ± 1.23 diopters (D) and -6.20 ± 1.52 D, respectively. T...

The objective of this study was to determine if increased overjet (greater than 6 mm) influences the magnitude and reproducibility of natural smile and maximal smile in Caucasian adult females. Twenty adult females with an increased overjet (6-10 mm) and 20 control adult females (overjet 2-4 mm) with no history of orthodontic treatment volunteered to participate. The mean age in the control gro...

Smile is a person’s greatest beauty asset. A defective smile might be considered as a physical handicap as the mouth act as a focal point where a large share of attention is directed toward mouth and teeth, it would be nice to have some sort of tools to assess beauty, which currently does not exist. Standards for beauty are actually a compilation and comparison of everything we have seen or exp...

We study imaging systems designed to assess the smile of laser diode bars (LDBs). The magnification matrix is derived from the required sampling period and the geometries of the LDBs and the charge-coupled device (CCD) array. These image-forming systems present in-plane pure translation invariance, but in the case of anamorphic ones, lack in-plane rotation invariance. It is shown that the smile...

A smile is a form of one's facial expression that widely used and easy to see. Having an aesthetic attractive can make person more confident when interacting socially in their environment. There are eight main components assessed smile, two which the arc gingiva display. Both have received lot attention because they known major influence on smile.The harmony gingival display will produce smile....

PURPOSE To characterize the early ocular-surface changes or tear inflammatory-mediators levels following small-incision lenticule extraction (ReLEx smile) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). METHODS Forty-seven myopic subjects were recruited for this prospective study. Fifteen underwent ReLEx smile and thirty-two underwent FS-LASIK. Corneal fluorescein (FL)...
