Date: April 2016. Source: Theses and Dissertations. Virginia Commonwealth University. Abstract: The purpose of this study was to investigate the social perceptions of subjects with differing lip position and facial convexity in three dimensions. A 3dMD camera (3dMD, Atlanta, GA) was used to capture 3D images of 9 subjects’ faces. The images were altered to…

Objective: The aim of the present study was to assess whether the use of platelet-rich fibrin (PRF) decreased the pain, swelling, and trismus levels of postoperative third molar surgery. Materials and Methods: In a double-blinded, split-mouth randomized study, thirty patients (6 male/24 female, mean age 20.32…

Highlights: • We assessed the reproducibility of the rest position using 3D soft tissue images. • 3D stereophotogrammetry images of a participant were acquired using 3dMD flex. • The reproducibility was assessed on the same day and 6…

Objective: To assess the range of social smile reproducibility using 3-D stereophotogrammetry and reverse engineering technology. Materials and Methods: Social smile images of white adolescents (N = 15, mean age = 15.4 ±1.5 years; range = 14-17 years) were obtained using 3dMDFlex (3dMD, Atlanta, USA). Each…

Highlights: • We present the first genetic associations with how old people look (perceived age) • Variants in MC1R, a pigmentation gene, significantly associated with perceived age • The MC1R association was independent of wrinkling, skin color, and sun exposure…
Date: April 2016. Source: Theses and Dissertations. Virginia Commonwealth University. Background: Past studies evaluating the esthetics of orthodontic treatment have been done using 2-D images. New 3-D imaging offers an improved, real-life representation of a subject. The purpose of this study was to determine how laypeople perceived differences in lip position (flat versus ideal lip…
Date: April 2016 Source: British Journal of Medicine & Medical Research 15(2): 1-11, Article no. BJMMR.25350. Abstract: 3D analysis allows for simulation of orthognathic surgery and prediction of aesthetic and functional outcomes. Our study aims to find common and repeatable parameters on the behaviour of soft tissues following bone movement by pre- and post-treatment by…
Date: April 2016. Source: PhD Thesis. Medical Sciences, Orthodontics, University of Alberta. Objective: To determine the predictive ability of the Alberta Pediatric Obstructive Sleep Apnea (APOSA) Index for orthodontic treatment need in pediatric patients with obstructive sleep apnea symptoms. Methods: Thirty orthodontic records, representing a spectrum of craniofacial and oral features and severity, were evaluated…
Date: April 2016. Source: International Journal of Dermatology. Background: Infantile hemangiomas (IH) are initially warm due to increased proliferation and perfusion then involute with apoptosis and reduced perfusion. Objective quantitative evaluation of IH treatment response is essential for improving outcomes. We applied a functional imaging method, dynamic infrared (IR) thermography, to investigate IH status versus…
Date: April 2016 Source: Biology of Sex Differences. Background: Although craniofacial sex differences have been extensively studied in humans, relatively little is known about when various dimorphic features manifest during postnatal life. Using cross-sectional data derived from the 3D Facial Norms data repository, we tested for sexual dimorphism of craniofacial soft-tissue morphology at different ages.…
