BACKGROUND The purpose of this study was to compare the refractive outcomes of small incision lenticule extraction (SMILE) in high-myopic patients with those of mild- to moderate-myopic patients. METHODS This study included 183 eyes of 92 myopic patients treated with SMILE using a VisuMax 500-kHz femtosecond laser. Treated eyes were divided into two groups, according to the preoperative spher...

Nowadays aligners have become alternative treatment in adult patients who do not want fixed orthodontic appliance due to various reasons such as aesthetic, easier care and clean food also don’t get stuck patient can smile with confidence aligners. Present case report demonstrates effectiveness of Clear used treat an female proclination upper arch having good periodontal condition. Predicted res...

OBJECTIVE To analyze differences in tooth display, lip-line height, and smile width between the posed smiling record, traditionally produced for orthodontic diagnosis, and the spontaneous (Duchenne) smile of joy. MATERIAL AND METHODS The faces of 122 male participants were each filmed during spontaneous and posed smiling. Spontaneous smiles were elicited through the participants watching a co...

BACKGROUND The smile perception of patients is not strictly related to standardized protocols and technical implications which certainly affect clinicians' decisions. The absence of maxillary lateral incisors could affect smile esthetics either with treatment or not. The aim of the present study was to investigate if different perceptions on altered smiles due to missing maxillary lateral incis...

How do people detect trustworthiness in others? Some researchers have shown that research participants trust smiling faces more than non-smiling faces. We examined cultural differences in this “smile effect.” We investigated whether three elements of a smile (smile intensity at the eyes, smile intensity at the mouth, and facial symmetry) would differently influence American and Japanese partici...

Purpose. To evaluate decentration following femtosecond laser small incision lenticule extraction (SMILE) and sub-Bowman keratomileusis (SBK) and its impact on higher-order aberrations (HOAs). Methods. Prospective, nonrandom, and comparison study. There were 96 eyes of 52 patients who received SMILE and 96 eyes of 49 patients who received SBK in this study. Decentration was calculated 6 months ...

BACKGROUND The purpose of this study was to associate smile esthetic judgment with dentofacial attributes of patients with unilateral and bilateral agenesis of maxillary lateral incisors treated with recontouring of canines or implants and patients with no agenesis (control). MATERIAL AND METHODS Forty-six participants were divided into two groups: those treated with recontouring (N = 26) and...

PURPOSE To observe the first 24-hour (h) outcomes of the small incision lenticule extraction procedure (SMILE) for myopia and myopic astigmatism. METHODS Fifty-three eyes (27 patients) scheduled for SMILE were followed immediately (0 h), 2, 4, 6, and 24 h after SMILE. Uncorrected visual acuity (UCVA), conjunctival congestion, pain level, and corneal edema, thickness, and densitometry were rec...

SMILE (Stanford Mobile Inquiry-based Learning Environment) is an inquiry-based mobile learning framework designed to promote student-centered inquiry and reflection leveraging mobile media in the classroom setting. Students can quickly create their own inquiry items based on their own learning and knowledge using SMILE. This paper introduces seven phases of SMILE that are applicable to math cla...

Smile detection is a specialized task in facial expression analysis with applications such as photo selection, user experience analysis, and patient monitoring. As one of the most important and informative expressions, smile conveys the underlying emotion status such as joy, happiness, and satisfaction. In this paper, an efficient smile detection approach is proposed based on Extreme Learning M...
