Taking into account the factors related to lip-tooth relationships in orthodontic diagnosis and treatment planning is of prime importance. Manual quantitative analysis of facial parameters on photographs during smile and speech is a difficult and time-consuming job. Since there is no comprehensive and user-friendly software package, we developed a software program called "Smile Analyzer" in the...

In this paper, we describe the development of two novel approaches to teaching math and science concepts to deaf children using 3D animated interactive software. One approach, Mathsigner, is non-immersive and the other, SMILE, is a virtual reality immersive environment. The content is curriculum-based, and the animated signing characters are constructed with state-ofthe art technology and desig...

A dynamic smile is desirable at all age groups and orthodontists are smile architects. To construct a beautiful smile the various macro esthetic and micro esthetic factors must be kept in mind. Frontal esthetics is very crucial and poor frontal esthetics can be very bothering for the patient. In this article we are presenting a case report on how a simple removable appliance addressed the chief...

The mental state of a person is judged by detecting smiles. The smile detection starts with the facial recognition. The main advantage of the smile detection is it ensures whether smiles are detected by the camera or not. We compare those set of images and determine which image has the best smile. Now, across the mouth region to detect the corners we use Shi-Tomasi corner detection algorithm as...

For decades, dentistry has been evolving into a profession that is extremely multifaceted and varied in its approach to both smile and facial esthetics. The coordination of macro esthetics (the face), mini esthetics (the smile), and micro esthetics (the dental esthetic component) offers a complete approach to esthetic planning. This article presents an expanded vision of esthetic treatment desi...

We investigated the correspondence between perceived meanings of smiles and their morphological and dynamic characteristics. Morphological characteristics included co-activation of Orbicularis oculi (AU 6), smile controls, mouth opening, amplitude, and asymmetry of amplitude. Dynamic characteristics included duration, onset and offset velocity, asymmetry of velocity, and head movements. Smile c...
