PURPOSE To compare toric implantable collamer lens (T-ICL), femto-LASIK, and ReLEx SMILE for the treatment of low to moderate myopic astigmatism in terms of long-term visual and refractive outcomes and predictability of astigmatic correction. MATERIALS AND METHODS The study included 30 eyes from 30 patients between the age groups of 21 and 40 years, undergoing bilateral surgery with any of th...

In the analysis of characteristics of a pleasant smile, a gummy smile has negative effects. A 25-year-old female patient was referred to the Marmara University, Faculty of Dentistry, Department of Prosthodontics. On the basis of radiographic, cephalometric and oral examinations, the patient was diagnosed with Class II skeletal malocclusion, high angle facial profile and partially edentulous. Th...

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...

OBJECTIVE To test the null hypothesis that there is no clinically significant difference between the post-orthodontic treatment images of smiles of subjects captured by clinical photography and the smiles of the same subjects obtained from digital video clips. MATERIALS AND METHODS Clinical photographs and digital video captures were obtained from 48 orthodontically treated patients. An updat...

INTRODUCTION Esthetics and attractiveness of the smile is one of the major demands in contemporary orthodontic treatment. In order to improve a smile design, it is necessary to record "posed smile" as an intentional, non-pressure, static, natural and reproducible smile. The record then should be analyzed to determine its characteristics. In this study, we intended to design and introduce a soft...

OBJECTIVES This study aimed to find the factors that affect dental esthetics and smile attractiveness in orthodontically treated patients according to laypeople's judgment, and to determine whether there is any relationship between dental and smile esthetics. MATERIALS AND METHODS Using the Q-sort technique, 60 laypersons (30 males, 30 females) rated dental and smile photographs of 48 orthodo...

OBJECTIVE The images of smiling people are omnipresent in marketing. Frequency, smile characteristics, context of the smile and target audience in newspaper advertisements were points of interest of this study. MATERIAL AND METHODS Four examiners analyzed 600 advertisements from 46 European magazines and newspapers by using content and framing analysis. Twenty items of the analysis form the p...

Insulin is the major hormone that regulates hepatic glucose metabolism by repressing gluconeogenic enzyme-encoding genes, and the counteracting glucagon/protein kinase (PKA)–inducible coactivating peroxisome proliferator– activated receptor g coactivator-1a (PGC-1a) signaling pathway is also well characterized in hepatic glucose metabolism (1–3). Until now, however, the regulation of the insuli...

The smile arc is defined as the relationship of the curvature of the incisal edges of the maxillary incisors and canines to the curvature of the lower lip in the posed smile. The ideal smile arc has the maxillary incisal edge curvature parallel to the curvature of the lower lip. Evaluation of anterior smile esthetics must include both static and dynamic evaluations of profile, frontal, and 45 d...

INTRODUCTION The purpose of this investigation was to broaden the understanding of how various skeletal, dental, and soft-tissue relationships are related to the esthetics of the smile in patients with malocclusions before orthodontic treatment. METHODS Images of the posed smile were captured from digital video clips of 60 growing patients (33 girls, 27 boys) seeking orthodontic treatment; th...
