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.

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)
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)
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)
INTRODUCTION This study was conducted to determine whether variations in the morphology, size, or shade of maxillary canines would influence perceptions of smile attractiveness in patients with canines substituted for missing maxillary lateral incisors. METHODS A smiling photograph of a hypodontia patient who had had orthodontic space closure with(More)
UNLABELLED Taurodontism is the morpho-anatomical change in the shape of a tooth, which involves enlargement of the body of the tooth and shortening of the roots. It has been reported in permanent and deciduous teeth, in premolars and molars and associated with certain syndromes, particularly in those involving an ectodermal defect. It has clinical(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)
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)
An idealised male image, based on Vitruvian Man, was created. The craniofacial height was altered from a proportion of 1/6 to 1/10 of standing height, creating 10 images shown in random order to 89 observers (74 lay people; 15 clinicians), who ranked the images from the most to the least attractive. The main outcome was the preference ranks of image(More)
