Factors Associated with Orthodontically Induced Apical Root Resorption of Maxillary Incisors
… Switzerland) for measuring RR of right and left maxillary central incisors. Using </p> <p>fiduciary markers at the anterior nasal spine (ANS), posterior nasal spine (PNS), and nasion (Na), movement of the incisors were assessed at three dental landmarks, the incisal edge (I), the center of …

Survival rate and fracture strength of maxillary incisors, restored with different kinds of full veneers : an in-vitro study
… artificial mouth. <br>Eighty, caries-free human maxillary central molars were used as abutments for the full veneers. The teeth were randomly divided into one control group and four test-groups of 16 samples each. In control group A, unprepared teeth served as a control. In the test groups, four …

Survival rate and fracture strength of endodontically treated crowned maxillary incisors with severe defects, restored with different post and core systems after exposure to the artificial mouth.
Sixty-four caries-free maxillary incisors were randomly selected for similar size and quality prospectives, were endodontically treated and received a 1.2 mm circular shoulder preparation with a subjective convergence angle of 6°. The crown was cut off 2 mm above the cemento-enamel junction. The …

Putting teeth into the developmental origins hypothesis: A longitudinal study of early childhood malnutrition, enamel hypoplasia and adolescent health in Amazonian Bolivia
… 2015. In 2015, we examined EH in the permanent maxillary incisors and mandibular canines using digital photography from which the following measures of EH were abstracted: occurrence (any, none), extent of occurrence (<1/3, 1/3-2/3, >2/3 of the tooth surface) and estimated age at occurrence (1, …

The Effect of Orthodontic Treatment on Sagittal Root Position of the Maxillary Central Incisor
<p>Introduction: 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 …

Early Childhood Caries in children 12-24 months old in Mitchell's Plain, South Africa
… unerupted), and visible dental plaque on maxillary incisors (Spitz et al, 2006) were recorded.The prevalence of ECC for the sample was 23.3% (dmft =0.88). The maxillary incisors had the highest prevalence of decay (14%) followed by the maxillary molars (4%). There was a significant …

Maxillary Incisor Crown Form and Crowding in Adolescent Orthodontic Patients
… to study <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 …

Three-Dimensional Evaluation of the Effect of Maxillary Incisor Retraction on the Palatal Bone and Root Resorption
… the 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, …

Cephalometric Evaluation of Bionator Therapy in the Early Treatment of Class II Malocclusions
… coming from mandibular growth rather than maxillary restriction. None of the dental variables differed statistically except the position of the maxillary incisors which were slightly more proclined in the two-phase group, and this was due to operator preference. The two-phase subjects had a …

Changes in Lip Position Coincident with the Movement of Artificial Teeth
… much change a given amount of movement of the maxillary central incisors will produce in the lips. Not only was the anterior-posterior position of the lips measured but also the amount of the interlabial gap was noted. Acrylic bite blocks were constructed. The maxillary one had wire pins …
