Date: May 2013. Source: Journal of Occupational and Environmental Hygiene, Volume 10, Issue 8, pp 419-424. Abstract: Twenty subjects underwent quantitative respirator fit testing with two styles (flat fold, cup-shaped) of N95 filtering facepiece respirators (N95 FFRs). Passing a fit test was followed by stereophotogrammetry to determine the face seal area and computation of seal…
Date: May 2013 Source: American Journal of Orthodontics and Dentofacial Orthopedics, Volume 143, Issue 5, pp 738-744. Introduction: Although natural head position has proven to be reliable in the sagittal plane, with an increasing interest in 3-dimensional craniofacial analysis, a determination of its reproducibility in the coronal and axial planes is essential. This study was…
Date: April 2013 Source: Facial Plastic Surgery.; 29(2): 106-15. doi: 10.1055/s-0033-1341588. Abstract: Three-dimensional (3D) imaging is a relatively new method of objectively evaluating surgical results, allowing the surgeon to accurately measure postsurgical changes with little inconvenience to the patient. Its accuracy and reliability has been consistently demonstrated in the literature. This article describes updated methods…
Date: April 2013 Source: The Cleft Palate-Craniofacial Journal Purpose: The aim of this study was to characterize three-dimensional (3D) facial morphological variation of children with cleft lip and palate compared to an age- and sex-matched control group. Materials and Methods: Subjects were 103 children aged 8 to 12 years old with cleft lip and palate—40…
Date: April 2013. Source: 2013 Bio-IT World Conference & Expo; Boston, USA. Abstract: With the support of NIH, we have developed the first quantitative normative database to diagnose craniofacial abnormalities. This new informatics resource, combined with novel methods in 3D surface imaging and 3D morphometry, provides the means of defining features of medical genetic conditions.…
Date: March 2013. Source: PLoS ONE.org. Purpose: Objective quantifications of facial asymmetry in patients with Unilateral Condylar Hyperplasia (UCH) have not yet been described in literature. The aim of this study was to objectively quantify soft-tissue asymmetry in patients with UCH and to compare the findings with a control group using a new method. Material…
Date: February 2013. Source: Dentomaxillofacial Radiology, Volume 42, Issue 2. Objectives: In recent years, one of the foci of orthodontics has been on systems for the evaluation of treatment results and the tracking of tissue variations over time. This can be accomplished through analysing three-dimensional (3D) orthodontic images obtained before and after the treatments. Since…

Abstract: The most common live-born human aneuploidy is trisomy 21, which causes Down syndrome (DS). Dosage imbalance of genes on chromosome 21 (Hsa21) affects complex gene-regulatory interactions and alters development to produce a wide range of phenotypes, including characteristic facial dysmorphology. Little is known about how…
Date: January 2013. Source: Human Mutation; 34(1): pp 14-22. Abstract: Three-dimensional (3D) facial analysis is ideal for high-resolution, nonionizing, noninvasive objective, high-throughput phenotypic, and phenomic studies. It is a natural complement to (epi)genetic technologies to facilitate advances in the understanding of rare and common diseases. The face is uniquely reflective of the primordial tissues, and…
