PURPOSE To evaluate corneal reinnervation, and the corresponding corneal sensitivity and keratocyte density after small incision lenticule extraction (SMILE) and femtosecond laser in situ keratomileusis (FS-LASIK). METHODS In this prospective, non-randomized observational study, 18 patients (32 eyes) received SMILE surgery, and 22 patients (42 eyes) received FS-LASIK surgery to correct myopia...

Smile is an irrefutable expression that shows the physical state of the mind in both true and deceptive ways. Generally, it shows happy state of the mind, however, ‘smiles’ can be deceptive, for example people can give a smile when they feel happy and sometimes they might also give a smile (in a different way) when they feel pity for others. This work aims to distinguish spontaneous (felt) smil...

background:   materials and methods:   determine possible significances in the relation of smile line to angle occlusion class, overbite and overjet and arch form. a p   results:   conclusion:   and important relation between some occlusal parameters and smile design, which must be considered. within the limitations of such studies, it might be concluded that there is a significant chi-square t...

In the past decade, there has been a remarkable upswing in interdisciplinary collaboration between dentists, orthodontists, and periodontists in smile enhancement, and now an entire field of “cosmetic periodontics” has evolved in collaboration with cosmetic dentistry. Contemporary orthodontic smile analysis is generally defined in terms of (1) vertical placement of the anterior teeth to the upp...

OBJECTIVES The study assessed the impact of facial height on attractiveness of smile, in association with the maxillary gingival display. This research was performed by dental professionals and laypersons. MATERIALS AND METHODS Frontal extraoral photographs were captured for both short and long faces. The photographs were modified using software for image-processing and three rater groups (or...

Objective. The current investigation was proposed to determine the impression of trained dental professionals and laypeople towards the modified smile esthetics. Materials and Methods. Twenty-six images were randomized in a survey and graded according to attractiveness by the orthodontists, general dentists, and laypeople. Photographs of gingival display, midline diastema, central incisor crown...

Facial expression analysis is an important field of research, mostly because of the rich information faces can provide. The majority of works published in the literature have focused on facial expression recognition and so far estimating facial expression intensities have not gathered same attention. The analysis of these intensities could improve face processing applications on distinct areas,...

PURPOSE To compare dry eye after small incision lenticule extraction (SMILE) and femtosecond laser-assisted LASIK (FS-LASIK) for correcting myopia. METHODS CENTRAL, Embase and PubMed were searched in November 2016. All randomized controlled trials (RCTs) and prospective cohorts that compared dry eye after SMILE with FS-LASIK were selected. RESULTS Five cohorts and one RCT were identified fo...

OBJECTIVE Submucosal minimally invasive lingual excision (SMILE) is a novel approach to address hypopharyngeal obstruction. This study compares the efficacy, morbidity, and complications of this technique to radiofrequency reduction of the tongue base (RFBOT), the current standard in minimally invasive tongue base reduction. STUDY DESIGN Retrospective analysis of data extracted from a prospec...

The role of a glucagon/cAMP-dependent protein kinase-inducible coactivator PGC-1α signaling pathway is well characterized in hepatic gluconeogenesis. However, an opposing protein kinase B (PKB)/Akt-inducible corepressor signaling pathway is unknown. A previous report has demonstrated that small heterodimer partner-interacting leucine zipper protein (SMILE) regulates the nuclear receptors and tr...
