Treatment Effects of Incisor Positioning on Anterior Tooth Display
… to determine the effect of changes in maxillary incisor position on anterior tooth display (ATD) in adult (n = 21) and adolescent (n = 38) orthodontic patients. The effects of anterior-posterior, vertical, and angular changes of the maxillary central incisor position during orthodontic treatment …

The role of CD133 in mouse incisor tooth epithelium
… in these cells. The continuously growing mouse incisor contains a large population of epithelial stem cells that drive the constant need for enamel generation. Using this model, this project aims to elucidate the role of CD133 in epithelial stem cell renewal and activation. After validating the …

Panoramic Radiographic Diagnosis of Molar-Incisor Hypomineralization in Permanent Dentition
… of panoramic radiographs for identifying Molar–Incisor Hypomineralization (MIH) in the permanent dentition of children and to compare the diagnostic performance of pediatric dental specialists with that of other dental professionals. Methods: This cross-sectional observer-based study was …

A Radiographic Analysis of Variance in Lower Incisor Enamel Thickness
… help predict the enamel thickness of mandibular incisors. At least two direct digital periapical radiographs were made for each of the 80 subjects. Radiographs were scaled to control for magnification errors using dental study models and computer software. Mesiodistal incisor width and mesial and …

Maxillary Incisor Crown Form and Crowding in Adolescent Orthodontic Patients
… <em>anatomical</em> crown form of the maxillary incisors, as measured from the cementoenamel junction (CEJ), in relation to crowding. The aim of this study was to evaluate the statistical association between maxillary incisor crown form and the extent of crowding in adolescent boys and girls who …

The Effect of Orthodontic Treatment on Sagittal Root Position of the Maxillary Central Incisor
… Sagittal root position (SRP) of maxillary incisors is an important factor in implant treatment planning. Kan et al defined four classes of SRP in an effort to aid implant placement treatment planning and these SRP classifications represent a novel approach to describing bone changes around …

Three-Dimensional Evaluation of the Effect of Maxillary Incisor Retraction on the Palatal Bone and Root Resorption
… effect of orthodontically retracting maxillary incisors on the height and labiolingual thickness of labial and palatal alveolar bone and incisor apical root resorption. <strong>Methods:</strong> Maxillary central incisor apical root resorption, labial and palatal alveolar bone height, and …

In vivo Measurement of Color Relationships between the Maxillary Central Incisor and Canine as a Function of Age
… between <em>in vivo</em> maxillary central incisors and canines to examine: (1) whether they share the same hue, but have different chromas (as commonly taught); and, (2) whether color differences (∆E values) change as a function of age.</p> <p><strong><em>Materials and …

Fractal Analysis to Detect Surface Roughness Changes After Fatique Loading in the Canine Mandibular Incisor - A Pilot Study
… structure from fatigue loaded mandibular central incisors of canine (hound) specimens. After fatigue loading experimental teeth, microcomputed tomography, was used to obtain 3-dimensional data of both the experimental and control teeth. Computer software was used to develop 3-dimensional models of …

Overbite Correction and Smile Esthetics
… used to reduce deep overbite: maxillary incisor intrusion using an intrusion arch and posterior tooth eruption using an anterior bite plate. Pre-treatment, post-overbite correction and post-treatment records were gathered from 32 patients who presented with deep overbite malocclusions to …

Overbite Correction and Smile Esthetics
… used to reduce deep overbite: maxillary incisor intrusion using an intrusion arch and posterior tooth eruption using an anterior bite plate and to assess their influence on smile esthetics. Pre-treatment and post-overbite correction records were gathered from 40 patients with deep …

Overbite Correction and Smile Esthetics
… that overbite correction, specifically maxillary incisor intrusion, will lead to flattening of the smile arc and consequently reduce smile attractiveness. The purpose of this prospective clinical study was to investigate differences in outcomes from two common treatment modalities used to reduce …

Molecular Control of Tooth Mesenchymal Stem Cell Activation
Background The continuously growing mouse incisor provides a robust model for studying molecular mechanisms of stem cell (SC) fate determination. While the epithelial SCs are well studied within this model, the identification and characterisation of a mesenchymal SC (MSC) population has yet to be …

COMPUTER-BASED IDENTIFICATION OF LANDMARKS IN CEPHALOGRAMS
… They were the sella, nasion, pogonion, menton, incisor superious, apicale superious, incisor inferious and apicale inferious. The original image was divided into smaller sub-images that contained the landmarks of interest, which were then analyzed accordingly. A windows-based application …

Long-Term Changes in the Dental Occlusion of Subjects Treated Orthodontically
… with age, accompanied by a 1.1 mm “relapse” in Incisor Irregularity during the posttreatment period. Arch depth decreased 1.3 mm during the posttreatment interval. Intercanine width was increased (2.2 mm) during treatment, but decreased (1.2 mm) towards the initial dimension after treatment. …
