OBJECTIVES To objectively quantify facial movement in response to facial expression and spoken word. DESIGN Experimental study. Setting - Department of Dental Health and Biological Sciences, University Dental Hospital, Cardiff, UK. EXPERIMENTAL VARIABLE Facial movement was assessed in response to a standardized smile expression and the utterance 'puppy'. The sequences were recorded using a ...

OBJECTIVES This article reviews an evaluation vector model driven from a participatory action research leveraging a collective inquiry system named SMILE (Stanford Mobile Inquiry-based Learning Environment). METHODS SMILE has been implemented in a diverse set of collective inquiry generation and analysis scenarios including community health care-specific professional development sessions and ...

INTRODUCTION Esthetic analysis of dynamic functions such as spontaneous smiling is feasible by using digital videography and computer measurement for lip line height and tooth display. Because quantitative measurements are time-consuming, digital videography and semiquantitative (visual) estimation according to a standard categorization are more practical for regular diagnostics. Our objective ...

Questioned by Hyub-Soo Lee Private Practice, Daejeon, Korea A1. In the past literature review, the relationship between smile esthetic variables and malocclusion lacked solid and sufficient evidence, therefore it aroused our interest to design a study of analyzing smile characteristics in different malocclusions. In our study, we found that arc ratio, upper teeth number showing, upper lip heigh...

This study aimed at evaluating the effect of intraoperative corneal pocket irrigation in small incision lenticule extraction (SMILE) and compares it to that in femtosecond laser-assisted in situ keratomileusis (FS-LASIK). Sixteen rabbit eyes underwent a SMILE procedure, with 8 eyes having corneal pocket irrigation, while the other 8 eyes were without irrigation. Another 16 eyes underwent a FS-L...

To evaluate the refractive outcomes of balanced salt solution infiltration during small-incision lenticule extraction (SMILE).This randomized prospective study enrolled 52 patients (104 eyes) with myopic astigmatism. Patients underwent SMILE to correct the myopic astigmatism in Daping Hospital of the Third Military Medical University between January and July 2013. One eye of each patient receiv...

The objective of the present study was to assess smile aesthetics after orthodontic treatment in subjects with and without the extraction of four first premolars. Post-treatment coloured frontal photographs (4 × 6 inches) of 60 Pakistani subjects, 21 males and 39 females, aged between 15 and 30 years were assessed by one examiner. For 50 per cent (n = 30) of the patients, treatment included the...

Facial expression recognition is one of the most challenging research area in the image recognition field and has been studied actively for a long time. Especially, we think that smile is important facial expression to communicate well between human beings and also between human and machines. Therefore, if we can detect smile and also estimate its intensity at low calculation cost and high accu...

Purpose: To compare visual outcome between Femtosecond LASIK and ReLEx SMILE in treatment of Myopia. Method: A single center prospectiverandomized clinical study in which patientswith Myopia +/-astigmatism were allocated to FemtoLASIK or SMILE group with 50 patients in each group. Main outcome measures were Visual acuity, safety and efficacy index; Contrast sensitivity; Aberrations; post-operat...

Small Incision Lenticule Extraction (SMILE) is a flap-free intrastromal technique for the correction of myopia and myopic astigmatism. To date, this technique lacks automated centration and cyclotorsion control, so several concerns have been raised regarding its capability to correct moderate or high levels of astigmatism. The objective of this paper is to review the reported SMILE outcomes for...
