The purpose of this prospective study was to help distinguish the relative contributions of heredity and environment to the external facial features and to assess the relative strength of the genetic influence on anteroposterior and vertical facial parameters, by using 3-dimensional optical surface scanning and the inferential twin method. The subject group(More)
The purpose of this investigation was to undertake an objective and quantitative evaluation of how mandibular prominence influences perceived attractiveness. The mandibular prominence of an idealized profile image was altered in 2 mm increments from -16 to 12 mm, in order to represent retrusion and protrusion of the mandible, respectively. These images were(More)
UNLABELLED Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anterior maxilla. They can cause a variety of complications in the developing dentition. This article reviews the epidemiology, clinical features, diagnosis and options for the management of supernumerary teeth.

AIM To compare part-time and full-time Essix-type retainer wear regimens following fixed appliance treatment, with respect to dental alignment and occlusal changes. METHODS In this prospective study, 60 patients were randomly allocated to either full-time or part-time Essix retainer wear following fixed appliance therapy. Study casts were taken before(More)
INTRODUCTION The purpose of this study was to assess the reliability of the Frankfort horizontal (FH), sella-nasion horizontal, and optic planes in terms of their variabilities in relation to a true horizontal line in orthognathic surgery patients. METHODS Thirty-six consecutive presurgical orthognathic patients (13 male, 23 female; age range, 16-35(More)
The study of the face and the ability to alter its form have fascinated mankind for thousands of years. The clinical ability to alter dentofacial form, whether through orthodontics, facial growth modification, or surgery, requires an understanding of facial beauty, including the evaluation of facial esthetics, proportions, and symmetry. The purposes of this(More)
INTRODUCTION The purpose of this prospective, randomized clinical trial was to compare the use of masticatory bite wafers with the avoidance of mastication in reducing pain and discomfort associated with initial orthodontic tooth movement. METHODS Eighty-four subjects (mean age, 14.1 years), randomly allocated to a bite-wafer group (BWG) or a(More)
PURPOSE The purpose of this investigation was to undertake an objective and quantitative evaluation of how severity of asymmetries affecting the mandible and chin point influence perceived attractiveness. MATERIALS AND METHODS The mandible and chin point of idealized male and female frontal facial images were altered in 5-mm increments from 0 to 25 mm and(More)
The purpose of this investigation was to undertake an objective and quantitative evaluation of how the degree of chin prominence influences perceived attractiveness. The chin prominence of an idealized profile image was altered in 2 mm increments from -24 to 12 mm, in order to represent retrusion and protrusion of the chin, respectively. These images were(More)
